Lighter, cheaper, good enough EF S and DX crop sensor lensesThere are downsides to crop sensor cameras, especially if you also have a full frame camera. The widest full frame zoom lenses, typically a 16mm 35mm zoom that covers 98 degrees horizontal at 16mm to 54 degrees horizontal at 35mm, aren all that wide angle on a crop sensor DSRLR. Lenses for full frame cameras fit on crop sensor cameras but not the other way around. The recessed lens rear elements of crop sensor only lens may get in the path of the larger mirror and if it doesn the image won fill the whole frame. APS C lenses are typically built to less costly standards and aren as bright (maximum lens aperture).

The Canon EF S 10 22mm lens for crop sensor cameras sells for about $725, and its maximum aperture floats from f/3.5 at 10 mm to f/4.5 at 22 mm. The Canon EF 16 35mm for full frame cameras costs twice as much ($1,500 street), weighs almost twice as much, is built like a tank, and Nike Torrey Smith Jersey has a constant f/2.8 aperture across the entire zoom range. So if you want to shoot low light wide angle photos, Canon has a lesser solution in its crop sensor cameras. Put the 16 35mm on the Canon EOS 7D and it covers a little over 60 degrees horizontally: about six turns of the camera to cover a full circle vs. four for the 10 22mm that covers 97 degrees horizontally (photo below).

Shooting a large group in a small room, or separating foreground and background outdoors while still maintaining the semblance of a normal photo without fisheye lens distortion, calls for a lens that covers at least 90 degrees horizontal. Nobody complains about the crop factor making telephoto lenses reach farther, except that the lenses are bulkier than need be if they were crop sensor only.

Of its nine EF S (crop sensor) lenses, Canon makes only one constant aperture f/2.8 zoom lens, the 17 55mm EF S IS f/2.8, priced at $1,050. No Canon crop Jimmy Smith Jersey sensor lens bears the L marking and red ring on the barrel that denotes Canon highest quality lenses.

For Nikon with DX (cropped format) lenses, it the same deal: the Nikon 10 24mm DX lens is $800 but the maximum aperture floats from f/3.5 to f/4.5. The Nikkor 17 35mm lens for full frame cameras costs $1,750 and it f/2.8. At maximum aperture, it admits about twice as much light.

Some pros and advanced amateurs find that no matter how many lenses they have, they can do most of their work with an ultra wide angle zoom and 70 200mm f/2.8 zoom (about $2,000). The lack of first class wide and wide to short telephoto zoom lenses for crop sensor cameras drives some photographers back to full frame. PR people for both companies say there nothing wrong with optical quality of their EF S (Canon) and DX (Nikon) lenses. Still, for twice the money, you might suspect there more to the f/2.8 wide angle zoom lenses than the improved light gathering. Many of the most serious full frame Canon lenses have gotten upgrades in the past couple years to make them sharper and lighter; they indicated by a II, as inCanon EF 70 200mm f/2.8L IS II USM. The one EF S lens that can be duplicated by using a full frame EF lens, the 10 22mm, dates to 2004.

Canon product deluge in 2012: All new except the 7DHere what Canon did in the last year to make 7D owners feel like orphans on shore watching the the party boat leave the dock. At the high end, Canon EOS 1D X, $6,800, delivers an 18 megapixel image, 12 frames per second for action shooters, and a shutter life of 400,000 frames (a lot). Canon refreshed the portrait shooter/wedding photographer favorite, the full frame Canon 5D Mark III, $3,000, with a 22 megapixel sensor and a 6 fps motor drive. Then it brought in an entirely new full frame camera, the Canon EOS 6D, a 20 megapixel model with a bargain (relatively speaking) price of $2,100. It has built in WiFi and GPS, SD not CF cards, good video, and ISO up to 25,600. This is the camera that had Canonistas wondering if the 7D was a goner. Not exactly: The 6D shutter is rated at 100,000 frames not the 7D 150,000, the auto focus isn on par with the 5D Mark III, and action shooting is 5.3 frames per second.

At the prosumer level, the Canon Rebel T4i (also called the EOS 650D and Kiss X6i outside the US) arrived at $800 with an 18 megapixel sensor, higher ISO rating (25,600 vs. 12,800), smarter processor (Digic 5), and better movie focusing (which is still so so). Canon also brought out its first mirrorless interchangeable lens camera, the Canon EOS M, $800. Effectively, Canon boxed out the 7D with new models offering more features. So what features does a high end crop sensor DSLR need to have to justify its existence?

Next page: The 7D Mk II in 2013: What can we expect?

Previous 2 of 3Tagged InOne reason I never bought EF S lenses is they couldn be mounted on APS H sensored cameras like the older EOS 1D II and EOS 1D III. I also had a full frame EOS 5D mark II since 2008, and couldn mount them there. I used to use a 15mm fisheye for ultra wide stuff on 10D, 20D and EOS 1D, and 16mm was enough on the 1D cameras. I now using a 7D for wildlife and sports with 70 200mm, 400mm and 500mm www.nflshopauthenticonline.com/nike-joe-flacco-jersey-c-1_53_57.html lenses.

However, I bought most of my lenses over 7 years ago, when everything was lots cheaper. Sure, a 400mm f/4 DO IS only costs a little more now, but the 16 35mm f/2.8L II and 70 200mm f/2.8L IS II are about twice as expensive. If I had to do it over again, I buy used gear. That what I did for years with Leica lenses.

People at Canon said the version II lenses, eg the 70 200, 300, 400, 24 70, 1.4x extender, etcetera lenses are significantly better image quality. They said that to me not to promote the Canon brand, I thought, but as a point of information. A couple of photographers speaking at Photo Plus, who were sponsored by Canon (for what it worth), said the quality of the VII zoom lenses have them seldom using fixed length lenses. There is that. There also is this: a used 300mm f/2.8, the must have lens when the 70 200 is not long enough for sports, wildlife, the family dog, is $4000 used and the 300 f/2.8 USM II is $7000. Actually, unless you a pro or cashed in on your Apple options, the $500 1.4x VII extender on the 70 200 is more sensible.

I wonder if clients could really tell the difference. Pro shooter Kirk Tuck once told me you could shoot salable stuff with a $99 (at that time) Yashica MAT 124 TLR.

He was right. I sold a book cover captured with an old F1n and the FD 35 105mm f/3.5, an inferior lens by most standards that lens spent almost as much time in the shop as on my camera. I also sold wildlife pictures shot with EF 500mm f/4 L IS and old EOS 1D mk II and EOS 20D cameras.

I use a cosmetically beat up EF 1.4X II for extra reach on some shots. My usual sports rig is EOS 7D with 70 200mm nflshopauthenticonline.com/nike-terrell-suggs-jersey-c-1_53_61.html f/2.8L IS and EOS 5D mark II with 24 70mm f/2.8L, 550EX or 430EX flashes on both for fill. That worked great at pro mountain bike races. For slightly more reach, I carry a 400mm f/4 DO IS. That also useful for handheld flight shots of wild birds.

I realize I probably not your mainstream amateur photographer, but I think the need for constant equipment upgrades is oversold by manufacturers. I saw that need to upgrade all the time first hand in the semiconductor industry for many years.

The pros who say you don need more than a simple camera for most photos of course they have way more than a Canon PowerShot in the equipment case. Many photos can be taken that way. Not football, auto racing, theater, dogs at play, shy children, or people with bulbous noses.

Lots of good soccer etcetera photos can be taken with older equipment with a long lens. Indoors, I once shot HS basketball long ago with a Rollei twin lens camera and a single on camera strobe and I always came back with a couple good photos (but I did not come back with a good photo of the key play of the game). But a newer camera with the most recent (not just cosmetically dinged) lens extender and most current lens will focus faster. I never be satisfied until all my sports photos are in focus, and going from 90% to 95% would also be a worthwhile improvement.

Denis Reggie, the Florida wedding photographer who commands $30,000 for the weekend, says the Canon version II lenses are so good he stopped carrying fixed focal length lenses. He gets by, so to speak, with a zoom fisheye (used for just a few shots), a 24 70 f/2.8 and a 70 200 Nike Jimmy Smith Jersey f/2.8 and one flash, with external battery pack, bounced off a side wall. In other words, a minimalist kit that costs $10,000, plus backup bodies and maybe a 16 35. He said this at PhotoPlus in NY at a seminar sponsored (paid) by Canon.

The Canon 400 DO (a long telephoto lens made very short by its special optics) you mention is is great except if you really must have f/2.8 for low light conditions.

I also have vacation photos from the late nineties shot with a miserable 3 megapixel camera and even those images are good enough to capture the magic of the vacation and I even made a 22 x 30 poster that looks pretty good if you stand back far enough.

Well it makes sense the final product is all that matters. Glass is very important to image quality but all other aspects are sort of on a level playing field as far as potential quality goes; expensive photo gear doesn take better photos, it makes good photos easier to take. A studio is a prime example where the flagship cameras totally fall flat, because most of the features that make them expensive are oriented towards field use any camera with a decent sensor that can pick up fine detail will produce professional results in a studio where you control the lighting and don necessarily need fast auto focus.

Bill, I actually see it moving in the reverse direction. I think we will see more full frame cameras getting cheaper and cheaper. I think we will see full frame mirrorless and even medium format mirrorless. For the latter, you could see a medium format camera in the same size as a todays full frame DSLRs.

My thinking is for this is even though there have been great advancements with smaller sensors, bigger sensors capture more light and can allow Game Torrey Smith Jersey for larger pixel sizes. Also going mirrorless and adding a larger sensor will be easier than increasing the advances with the same or smaller sensors. Additionally, Sony is pushing the old boys kicking and screaming to the mirrorless prosumer market.

You hit on the right reasons for the uptick in full frame DSLR announcements. All things equal, 18 megapixel full frame sensors will be higher quality than 18 megapixel crop sensor sensors. Against that, there history: Tech devices get smaller. Sometimes the next smaller device takes a while to match the quality of the older, bigger device. And it could very well be that the even smaller MILCs will win out. But in the meantime I think, hope there a couple more generations of APS C sensor DSLRs.

the world around them, in a single glance, it works with the brain to tell them size, conformation, color and also the texture of an object. Their eyes tell them how far or how close an object is, whether it is moving or still. Eyes, also work with the nerves and brain muscles to produce complicated messages and visual images. All parts of an eye are extremely delicate making it necessary to protect them at all times. Eyes are also protected by tears, they moisten and cleanse and protect them from irritants.

James had some kind words for Stern, who will be involved in his final ring ceremony. Stern will retire on Feb. 1, turning over the business of running Joe Flacco Jersey the NBA to his deputy commissioner Adam Silver.

"What he's done is unprecedented in his 30 years," James said. "The vision he had to make this game global and to broadcast these players and to broadcast these teams and this game of basketball world wide is something, I don't know, maybe someone else thought of but they couldn't bring together and make it happen like he did.

"He had a dream and he had Elite Terrell Suggs Jersey a vision and he went for it."

The Heat have had mixed results on ring night, being embarrassed by the Bulls by 42 points after raising their first banner in 2006 and defeating Boston 120 107 last year.

"It's a challenge," James said. "Once Nike Joe Flacco Jersey the competition gets going that definitely helps but it's definitely a challenge."

Coach Erik Spoelstra said its www.nflshopauthenticonline.com/nike-torrey-smith-jersey-c-1_53_63.html about compartmentalizing.

"We've had to learn how to do that for three straight years in so many different circumstances," Spoelstra said. "You hope that helps you in a circumstance like this tonight. We've always had to deal with something outside of the game. That's something we can't control but we do want to respect the night especially nflshopauthenticonline.com/nike-jimmy-smith-jersey-c-1_53_62.html for our fans and everybody in the organization.

"Most of us have been around for 18 years and we've had some lean years together. We've Game Terrell Suggs Jersey also had some years that have ended very poorly and that is the part I enjoy, not only for our players or guys that didn't have a ring from the year before, but seeing guys that you have been in the trenches with for years and have been through those lean years and we survived together."

After crushing us December through February, winter has gone away with barely a whimper this March. So far this month, we've reached 50 or better every day except March 2, 3 and 4 that's 13 out of 16 days. Recall we hit 50 just once the entire month of February. Last March was much fiercer by comparison, when we only made it to 50 or higher on 6 out of the first 16 days, with a streak of 5 consecutive days in the 40s March 12 16.

Keep reading for more on the rapid switch http://www.packersnflofficial.com/Nike-Micah-Hyde-Jersey.html to above average temperatures this March.

For the last 12 days temperatures have been above average. Even our recent cloudy and cool stretch (Friday through Monday) ended up above average (each day) because of relatively mild nighttime lows. Amazingly, the temperature has not dropped to freezing at National Airport (DCA) the entire month. The last time it hit freezing was Feb. 27 (when it dipped to 31 http://www.packersnflofficial.com/Nike-Andrew-Quarless-Jersey.html degrees). Last year on the other hand, we had three straight nights in the teens in early March (March 2 4).

Might we not experience Elite Haloti Ngata Jersey a freeze the entire month of March at DCA? It's possible, as mild weather is expected for the next five days. On the other hand, there is some indication of a shot of cold air next week.

For those who consider winter over according to the meteorological definition of March 1, this year's weather certainly supports that notion based on the observed weather of March 1 16 and the forecast weather of March 17 20. Of course, by saying that, we'll probably get a blast of cold and/or snow to end the month (as in 1891 and Nike Haloti Ngata Jersey 1942: March is fickle).

For practical purposes the threat of snow is probably gone until Dec. 5, 2010. We could still Jamari Lattimore Jersey get some conversational flurries during the next month, however.

The primary threat this spring will involve hail. Hail is more likely before June 15 because the air at higher altitudes is still cold from the past winter. In fact, the combination of rapid surface warming, moisture advection and leftover cold air aloft during April is what's responsible for the frequent "April showers". Instability precipitation reaches its height next month, and may continue off and on through July since ground heating is strongest under the direct sun at the summer solstice. So far tonight, I am recording the highest temperature at 52(F), while most others are between 44 46(F). At Jamari Lattimore Womens Jersey the same time, my RH reading is around 35%, whereas the other locations with lower temperatures have RH readings of between 60% 80%. I have always noticed that it becomes more humid at night, as opposed to the daytime, especially when temps. are warm, but I've never pondered the relation between Temperature/RH variations such as I am witnessing firsthand now. Could someone please explain what I am witnessing here? I know that the RH generally decreases with daytime sunlight/heating, and vice versa, but I'm simply wondering why my readings are managing to stay drier and warmer than many of the other surrounding spots.

Btw, my low temperature readings often reach roughly the same temps. as the other stations nearby right around sunrise, but it simply takes mine longer to achieve such. I live in a slight gully, with a creek out back, and my station is situated about 15 20 ft. above the ground (5 7 ft. above the surface of the wooden deck (Which is away from any artificial heat sources)). It also has a Passive (Gill) Radiation Shield.

Colorado's Spencer Dinwiddie drives past Georgia's Charles Mann on Dec. 28 in Boulder. The Buffs open Pac 12 play on Thursday when they host Oregon State"I think (the Pac Micah Hyde Jersey 12) is in a much better position than it was at this time last year," said Ernie Kent, the former head coach at Oregon and currently an analyst for the Pac 12 Network.

Three Pac 12 teams (No. 1 Arizona, No. 10 Oregon, No. 20 Colorado) are ranked among the Associated Press Top 25 this week, and UCLA has been receiving votes most of the years. Eight of the 12 teams were among the top http://www.nflshopauthenticonline.com/nike-haloti-ngata-jersey-c-1_53_56.html 65 in the Sagarin power ratings this week.

Kent said that having the No. 1 team in the country is a big deal for the Pac 12 because "you've got the focus back out on the West." It certainly helped Andrew Quarless Womens Jersey the Pac 12's reputation when Stanford went on the road to beat then No. 10 Connecticut.

A year ago, the Pac 12 made a big leap forward by Andrew Quarless Green Jersey sending five teams to the NCAA Tournament. The conference might be strong enough to top that number this year.

"As long as the right schools beat each other up, Micah Hyde Kids Jersey they come out of conference play in good shape, with potentially five teams, I think," Kent said, "and maybe depending on who that team is . there could be a sixth or seventh team sitting there."

Conference play gets underway on Thursday night, with 10 of the 12 teams in action. Like Kent, Colorado head coach Tad Boyle believes the conference has been every bit as good as advertised, which suggests a fun couple of months ahead.

Oregon's Joseph Young, left, drives past Morgan State's Blake Bozeman in Eugene, Ore., on Dec. 29."You look at the standings and you see Stanford in the middle of the pack; they're as talented a team as anybody in the league," Boyle said. "The way you judge packersnflofficial.com/Nike-Jamari-Lattimore-Jersey.html a league is not necessarily at the top of it. Every league's got good teams and good players at the top of it. It's the middle of the pack and the lower end."

Bolland, who scored the Stanley Cup clincher for the Chicago Blackhawks last season, got the game winner in overtime as the Toronto Maple Leafs beat the Edmonton Oilers 6 5 in a back and forth game Saturday night at Air Canada Centre.

Bolland finished off a 3 on 1 rush with Cody Franson and Mason Raymond just over two minutes into the extra period. He now has three goals on the season, two of them game winning goals.

"We have confidence, we just don't give up," Bolland said. "In Chicago, when I was there, we'd be down 5 4 or 5 1 against teams and we knew we could come back. We have that feeling in Sam Shields Green Jersey the room. If we're down, we can come back."

Bolland's goal came after Joffrey Lupul had tied the game in the final minute of regulation with goalie Jonathan Bernier pulled for an extra attacker.

"We got a lot of experience in here, a lot of character players," said James van Riemsdyk. "We don't ever quit and that's a huge attribute to have . We never seem to stop playing and that's key."

The win improved the Leafs' record to 5 1 0, while the Oilers, who began a six game road trip, dropped to 1 3 1.

The lead changed hands six times and neither team was up by more than a goal at any point of the game. Mason Crosby Youth Jersey

"It was back and forth, and we kept coming," said Leafs captain Dion Phaneuf. "That's probably one of the most momentum swings back and forth, back and forth that you're going to see. We'd like to come out on the winning end and we did."

Lupul and Van Riemsdyk each had two goals for Toronto, and Nazem Kadri had the other. Bernier, making his third straight start, stopped 26 shots for the win.

Ryan Smyth replied with a pair of goals for Edmonton. Ryan Nugent http://www.packersnflofficial.com/Nike-Julius-Peppers-Jersey.html Hopkins, Boyd Gordon and Jordan Eberle had the others, while Devan Dubnyk made 20 saves and Mark Arcobello added three assists.

"Our guys were battling hard and we couldn't keep the surge from coming," said head coach Dallas Eakins. "I thought we were doing a lot of great, great things and it just seemed like that puck kept coming in our net."

The opening period was an omen for things to come as the teams each scored a pair of goals.

Edmonton opened the scoring just over five minutes into the first on a controversial goal. Bernier went behind the net to play the puck around the boards and Eberle clipped his right foot as he tried to squeeze between Bernier and the post. Bernier tripped, Eberle got the puck out front and it deflected off Smyth's skate over Bernier as he scrambled back into the net.

"I thought I made the right play," Bernier said. "He kinda caught me from behind, so that's why I was late on that play. But that's part of the game and that's the referee's call."

Toronto tied the game at 9:47 on a weak goal. Kadri took a pass from Raymond at the left faceoff dot and roofed a wrist shot over Dubnyk just a few feet from the goal line.

The Leafs took the lead on a power play goal at 15:26 of the period. Van Riemsdyk tipped a wrist shot from the point by Cody Mason Crosby Kids Jersey Franson past Dubnyk for his fourth goal of the season.

The Oilers got that goal back with less than two minutes left in the period on a 5 on 3 power play. With Colton Orr and Van Riemsdyk in the penalty box, Nugent Hopkins snapped a shot from the slot that snuck between Bernier's right arm and his body into the net.

The teams split a pair of goals in the second period, and the back and forth hockey continued in the third.

After Eberle and Van Riemsdyk exchanged goals, the Oilers reclaimed the lead at 11:27 to make it 5 4 when Smyth got his second of the game, finishing off a passing play from Eberle.

That lead stood until the final minute of the third when Lupul tied it with a shot from the bottom of the left circle, allowing Bolland to complete the comeback for Toronto.

"My teeth are going to be ground down by the 20 game mark if we keep playing the way we did tonight, as far as exchanging chances and mistakes," Carlyle said. "But hey, that's hockey and it's early in the season. I'm sure we're going to see a few more like this along the way. We're just fortunate we're on http://www.packersnflofficial.com/Nike-Morgan-Burnett-Jersey.html the extra point side of it."

NOTES: David Broll, a Leafs sixth round pick in 2011, got an assisted on the Leafs' third goal Sam Shields Womens Jersey for his first point in the NHL. Edmonton's Nail Yakupov, who has no points in four games, was a healthy scratch for the first time in his career. . The Oilers have given up at least four goals in every game this season. . Announced attendance was 19,379.
