The difference with 600gm is just outside the center, some little AC that causes loss of contrast (but is also recoverable), and we are talking about 100%crop.....which is not about photography but about the passion for microscopes.
If "some little" CA doesn't bother you, I rather don't understand why you plonk 6 grand on a lens. But hey, I do see value in microscopes, so maybe that is my problem. Not the fact that I like printing big from cropped images. /sarcasm
I have a hard time seeing a worthwhile improvement in the IQ of the 300GM&TC2 vs the 200-600 in those TDP crops. The aberrations of the TCs on the short prime seem *very* similar to what happens on the longer primes. While per pixel it is a tad better when using the same TC on both primes, the TC2 on the short prime seems worse everywhere compared to the 600GM with the TC1.4, which is of course quite a step down from either prime without TC.
Anyway, that is what I see in these crops. TCs still do what they do. That said, I have use for a "shorter" prime and am quite tempted by this little gem.
