Standard lenses vs. Canon L-series

[lacla]

Thanks a lot for the excellent replies! I'm a lot wiser now. Thanks especially to cfusionpm - that was exactly, what I was looking for! That difference is quite remarkable, I must say! I'm quite stunned actually...

bazooka, I took a shot in the dark and did some googling which gave me this:

Canon EF 35mm f/2.0 Lens - Canon EF 35mm f/1.4 L USM Lens Comparison - ISO 12233 Resolution Chart Results

Is that the site you remember? It's a pretty good comparator, but the cameras differ for different lenses which is sort of like comparing apples and oranges, I suppose.

Hint: they look good too.

It's preferable turning up at a shoot with a, say 70-200mm f/2.8 IS, than a 55-250mm kit lens.

They do attract a lot of attention; wanted or not
