About Olympus 75mm F1.8 lens



1:1 crop

If I posted the picture above without comments some might probably consider it a decent potrait. It's 0.8 megapixel resolution, many people post pictures of that size, resized for web.
What makes this picture outstanding is that it's actually a crop of larger image (which itself is a crop due to my suboptimal framing):

And I can't resist from posting this crop to illustrate the amount of detail this lens resolves:



1:1 crop, 75mm



full frame

According to Roger Cicala from RensRental Oly 75mm resolves 880 Line Pairs/Image Height in center at F1.8, and at F2.8 it resolves 1020 lp/ih.
By the same measurement Panasonic 35-100mm at 100mm and F2.8 resolves only about 630 lp/ih.

Even if we consider Oly's resolution to be 900 lp/ih at F2.0 (it's probably better), cropping and magnifying Oly 75mm image gives resolution better than Pana zoom would have cropped to 107mm FL FOV. And I would have to raise ISO one stop more for F2.8 aperture. IMO, for low light telephoto reach Oly 75mm is a clear winner, a great lens to capture shows from far away.





From behind the crowd, camera handheld as high up as I could
