As from my previous post, i have a question. Why buy the new stuff? We all hear the advertising blurb about this lens is better than the old one etc, but in the real world......is it? Whilst we study the various charts on this site and others, zoom in to %100 look for this bit of sharpness over others we can see that technology moves on. But does it? We miss one massive variable. Who zooms in to %100. No one. The issue is, will you notice any differance on what you print. The answer is....no. Unless you print big.

I therefore make a challenge.

I will donate £100 to charity to anyone who can make a shot with Canons latest lens, 200, 300 500 do the same shot with the old lens, on the same camera,paper etc print at A3 on the same printer and can notice any differance.
