Minolta 28-70mm G vs 28-75mm D on Sony A900

Same test as previous gallery : https://pbase.com/nadeauf/2870g_vs_2875d

Except this time with Full Frame Sony A900 but reduced to 12mpix and compressed at 75% from RAW files in lightroom.

Even, some modification in the exposure of the G lens to link to the D lens. At same aperture and focal, the brightness the exposure is not exactly the same.

Je ne pense pas que ca vaut la peine lorsque vous avez une bonne copy de la Minolta 28-75D 2.8 (pour le prix premierement, et ensuite la taille et le poid).

Moi de mon cote j'ai opte pour switcher dans le monde des Primes ... , j'ai vendu mes dernier Zoom il y a une semaine.

La 28-75D en bonne condition et de bonne qualitee optique va rester un classique.

La 28-70G est tres bonne, sauf que elle peut rendre les gens nerveux par le fait qu'elle focus pas tres tres vite et aussi son close focus distance qui peut devenir tres derangeant si on veut faire certaine composition. Je dirais que son gros point negatif est vraiment sa distance de focus.

Voila,

Frank

Merci pour ce test.
J'ai également le 28-75D avec l'A850 mais il semble que le votre possède un problème de flou du coté droit.
Est ce que ça vaut le coup de le changer pour le 28-70G voir même le CZ 24-70 vu la différence de prix ?
