In the FA31 pic I could read the film box, but the Sigma pic blurred it (extreme edge of the frame).
I think you're right with your observation here. The FA31 is probably the superior lens, but the difference between it and other, more affordable lenses like the Sigma, is a bunch of small improvements rather than one big improvement. If you can take a photo with the Sigma, it won't automatically be a better photo with the FA31. You'll just get more consistent results over time.
I would add that in addition to noticing the difference in printing environments, the extra detail can come in handy when you're editing your photos, in situations like cropping, etc.
It was interesting that you mentioned the Canon 35 1.4L in your first post, because the images from the FA31 really remind me of images I've seen from that lens and the Canon 24 1.4L. It's hard to compare directly, since most of the images you see from those two lenses are on full frame cameras, but the point is, there's probably a reason these lenses are all above $1,000. Too bad the FA31 doesn't have that nice silent ring motor
I suggest if you decide to get a FA31, you wait to buy one used. If you can get one for say, $800-900, then sell your Sigma for say $300, that's just $500 you're spending. Much better than $1,400
