they tested lenses with body and display the result. as you can imagine the same lens used on a 10D can be good and terrible on a 1DS...the result are almost what i expected.....except when i looked at the nikon part....the contrast of the nikon lenses are less than impressive compare to the canon's one....or even sigma one for some.
if you can buy a copy of the mag do so it is a must have.
this month issu was on wide angle zoom...next month tele zoom and after that primes....
vigneting : good from 5.6 before that can be notice.
chromatic aberation : some but discreet
distortion heavy from 15 to 20 but nothing inusual for a wide angle.
quality very sharp from 5.6 to 11 but diffraction kicks in after F11
Seems interesting... Actually I usually prefer Réponse Photo for quality, but I have seen their announcement for the lens test and I was curious... I'll certainly buy it later today...
I wonder if they prefer the 17-35 to the 15-30 from Sigma... It seems that French magazines prefer the 17-35 while the whole world stated since long that the 17-35 is crappy and the 15-30 was a fortunate error :-)
