I'm certainly not going to argue that the Jupiter 8 I used in the photo referenced earlier this thread would hold up. At the same time, my shot was taken at f/2, hand held at 1/5th or so. It isn't a great reference image for sharpness. As a sonnar lens, it shouldn't be in the same ballpark when it comes to corner sharpness as your lens. Certainly a great lens and an incredible bargain.
I am flattered that my photo was referenced in comparison though.
Oddly enough, I almost picked up a 101st kit last week. I came across a very nice one for $600 - thought about selling the body and keeping the lens and finder. Just couldn't justify it though as I picked up a very nice Elmar f3.5 a week earlier.
