Ziess 35mm f2 for Mac

I am rather impressed with is lens for close up shot, being cropped this mu ch and still having the detail and being as sharp as it is

Hard to tell, not just because of the low resolution of on-screen displays, but also because it shows signs of oversharpening--strong halos along some edges, particularly toward the top--which will create an impression of sharpness. Most true macro lenses are very sharp, but to get a clear view of how this one stacks up, I would want to see a link to the full-sized image, with no sharpening applied.

 

I do a lot of macro, and in my experience, the amount of cropping can overwhelm lens quality. Even if one had a perfect lens, severe cropping degrades sharpness, depending on pixel density.
