Originally posted by nocturnal I have two M 75-150/4 lenses but never used one in anger on DSLR. I have used them for film mostly but haven't enlarged the negatives yet so don't know! Surely the Tamron is much superior or not?
The 75-150 is a very good performer, and despite owning the Tamy, i will keep it and use it.
The 75-150 has a very subtle softness wide open while having a lot of micro-contrast, making it perfect for portraits : sharp eyes, skin is a little softened, hair and such are quite well rendered.
Stop it a stop and it's very sharp, has good micro-contrast, good contrast but not too much, making it a very good lens if you plan on editing all the picture or footage because you have a lot of latitude when it come to saturation / desaturation, sharp /soft, etc.
Colors rendering is very constitent with the more modern high end lens, like the DA*, DA ltd, FA ltd, which makes the editing easier.
Only complain : it's not a A lens
It's light and small which is great to make a smaller kit.
The Tamron is like the M75-150 : a little soft wide open, sharpen a lot at f3.2, is plenty sharp at 3.5.
Besides that, i can't tell much, i havent used it really since i received the lens.
You should try the 75-150 on DSLR, is quite nice to use !
