    Old 85mm OM versus 85mm Samyang

    Both cost about the same on Ebay. Samyang (Opteka branded) 85mm f1.4 versus Olympus OM 85mm f2.0.

    Very interesting results. To start with, I thought the Samyang looked much sharper, but when looking more closely, it seems to be more contrasty rather than sharper. Apart from a slight yellowish cast, which can mostly be corrected during pp anyway, I think I would prefer the Olympus.

    which something I think most people get confused about and say something is more contrasty when they mean its sharper ... :-) I've been really happy adding a wee bit more contrast to lenses which need it in photoshop with large radius unsharp masks, but there is no fix to absolute sharpness.

    somehow I seem to have lost the significance of what I intended to say

    oh well

    I'm just

    Yes, under the haze, the Olympus seems as sharp or sharper. Not surprising, most slower-designed lenses (50mm f1.8 versus 50mm f1.4, for example) tend to be sharper.

    The Sun was stronger when the Opteka shots were taken!

    I was more concerned with the sharpness. Had the sun been stronger with the Olympus, colour error would have been worse than it is. The overall haze on the image in this case isn't spherical aberration, it's chromatic aberration.
