| p.1 #1 · Anyone's Sigma 50 1.4 sharp but soft at the same time? |
i'm on my second sigma 50 1.4. had the old one with old finish and on my d700 it just was back focusing and also very soft so I sold it and picked up a new one with the new finish from BHphoto.
Lens focuses properly and doesn't back or front focus's so far however @ 1.4 wide open it still seems soft especially compared to my sigma 35 1.4
What I mean is @ 1.4... the images are perfectly in focus but they seem soft as in not contrasty??
does that make any sense?
I AF fine tuned against a chart and +10 was the best out of the bunch from -20 to +20
I have made a +10 adjustment using AF Fine tune and it seems to help but it still seems soft.
here are some examples.
i see so many people say they have a "super"razor""sharp as a tack" copy
it makes me think either it really is that sharp wide open OR everyone has different levels of acceptable sharpness wide open and they all have different versions of "razor" and sharp as a tack" definitions.
These are all SOOC and converted from Raw to Jpeg and that's it. no exposure/clarity/contrast/sharpness added just SOOC.
Part of me understands that the reason we have AF fine tuning is because every lens camera combo is different.. I just hate being that guy that had the odd combo mean while so many others have no issues and like to say they needed 0 AF fine tuning on their setups.
Here is a test chart with camera/lens from about 2 ft away and with +10 AF fine tuning.
