un autre test qui , de memoire , confirme globalement sauf un chouia ac pour le fixe
http://www.dyxum.com/dforum/24mm-cz-vs- ... 68630.html'-the coma is better corrected at f/2.8 on the zoom (surprising but true) (coma is gone at f/4)
-the prime has a small amount of longitudinal chromatic aberration
-at f/2.8, the prime extreme corners are slightly more blurred than the zoom corners (coma again)
-at f/2.8, the zoom is slightly less sharp than the prime in zone B (around the corners of the APS-C frame)
-at f/4-f/5.6 the corners of the prime clean up nicely
-at f/8-f/11 the corners of the zoom clean up nicely
-the prime has less distortion
Does it make the prime a "must buy" lens? Now, that is an entirely different question. The competition (Nikon and Canon) has f/1.4 24mm primes, f/2.0 is not a big gain over f/2.8. Compared to the CZ24-70, the prime will probably make exactly the same pictures in 99% of the cases (if you correct distortion)
Le top semble etre le 24 + le 50 au lieu du 24/70 - sauf si on prefere/pas le choix , un zoom
Pour ma part j'en cherche 1 a un prix + waf
