Using printer paper is not the best idea. A lot  of papers contain chemicals to brighten it, which make the paper not neutral grey, but blue (ish). So if you use "bright white" paper for WB, your...

Yes!!! It is totally worth it. The IS works like a charm, you get 3-4 stops of stabilization. Think about what 3 more stops mean. It is the difference between full sunshine and heavy clouds. Or...

Yes IS is a great thing, it helps getting sharper pictures all the time, not just in low light, or at small apertures. My tests showed me, that sometimes even at 1/500s, IS can give you better...

Since I got my 24-70 I, it has been my most used lens. It does everything (except wildlife/ bird) and it is very good. One problem is heavy use might wear out the lens faster than expected. My copy...

Like today, Canon had 3 grades of lenses. The kit lenses were the lowest tier. They are all plastic, rotating front element, small filtersize, f/5.6 at the long end, loud AF sound. best thing, they...

I would go for one of the old analog Rebel kit lenses like this one http://www.canon.com/camera-museum/camera/lens/ef/data/standard_zoom/ef_35~80_4~56ii.htmlThey should be pretty terrible in terms...

I don't think so. The only lenses that work with larger formats are the TS-E lenses. The "strange" lenses like 24 and 28 IS were long overdue upgrades of midrange primes. They added IS for video...

I missed that you said that in your first post. Well, after rereading I thing you need two cameras. One for low-light and one for sports.Is your 60D working for your sports shoots? AF tracking,...

One thing to consider is reach. If you shoot sports, do you have the focal length you need now. On FF 300mm is about the same as 200mm on APS-C. If you need your extender to get the shoots you want...

One thing to check first. Is your lens the 28-105 f/3.5-4.5 USM? This is "the good" one. There were other 28-105mm lenses from Canon that had very bad image quality. I own and have used the USM...

As a rule of thumb, 1 stop doubles the price of a lens, IF you keep everything else nearly the same. EF 17-40 f/4 vs. 16-35 f/2.8 or 70-200 f/4 vs f/2.8 (I) were lens pairs with similar...

The 50mm 1.4 is great on FF, fast, light, not to expensive. I fear there is no ideal lens from Canon for this purpose. The L's are huge and expensive, 28mm and 85mm f/1.8 are soft wide open, so for...

Looks good. One thing. 50mm on a 7D is way different compared to 50mm on FF. If you use your 50mm lens for portraits, get the 85mm 1.8, 100mm 2.0 or 135mmL or 100L. 50mm is not great for tight...

This lens is pretty solid, except for the extreme corners at 17mm the images should be sharp. One thing worth checking on all wide lenses is the centering. Is the image sharp and in focus on both...

I used a 28mm on both FF and APS-C cameras. It is not the greatest lens out there, but a good sample should have good image quality, at least in the center. Here is a test i made at f/2. For...

The EF-S 55-250 is great, especially for its modest price. Very sharp at f/8 - f/11. With the 70-200L lenses you pay a lot more for brilliant IQ at wider apertures. My 70-200 f/4 L IS at f/4 is...

You are very brave. I would not dare to disassemble such an expensive and complex lens. Good for you that all worked out well and that your lens is fine. Happy shooting.

The best wide lens around is the TS-E 17mm. (I only read reviews and looked at images made with this lens). IQ is great. TS-E lenses are great.I use a 45mm TS-E if I have the time to carefully set...

Deep shadows look the same as before to me.

LR4 works fine after the FW update. It reads the ratings (I love this), otherwise nothing new.The in camera lens correction is worse than LR4s. At least with a 28mm 1.8, the distortion...
