Numerous times I've thought about selling my Sigma 85mm 1.4 art because it's too big on the FTZ for my liking and so seeing this thread come up has inspired me to look further....especially as the sharpness vs character conversations have shown more balanced appreciation towards character lately. If anyone is in a similar boat to me, I thought I'd share this comparison I found online (I had to translate to English of course):
These types of reviews / comparisons are the best in my opinion.....better than charts. Also love the variation of compositions rather than just tight shots to compare bokeh (which is fairly unhelpful most of the time).
