Great RedCrown 2010-04-26 4:25

Stunning image, impossible to fault Usually, I would argue such an image works better in B&W but the use of colour here even accentuates the contrast. Excellent sharpness too (something I never managed from my copy of the Canon 17-55/2.8).

Indeed, but it was maddening to have to stop down a rather expensive f/2.8 lens to achieve a decent sharpness. When I switched to FF, I sold it and bought the 24-70/2.8 which is not much better in all honesty!

Actually we ought to discuss not about sharpnes but about deep of fields. When you take photo of the face from rather short distance if you want to have all the face sharp you must apply f>5,6...

Of course you are right, my friend. DoF is more important here. But nevertheless, I found the 17-55 disappointing at f/2.8.

When I spend a fair sum of money on an f/2.8 lens, I want to be able to use it at f/2.8 without appearing that I used a Coca Cola bottle instead!

Do we talk about the same lenses? Canon FS 17-55 IS 2.8? I'm very glad of using it even with f.2.8...

Regards.
