Yes.
Originally posted by Asahiflex I use old MF lenses on almost a daily basis, and CA issues are few and far between... My S-M-C Takumar 135mm f/2.5 is definitely not a CA machine, I really like it. Of course, there IS some CA present but only if you pixel peep. It's never very prominent though. The worst lenses in that regard that I owned were the Komura 85/1.4 and SMC Pentax-M 85mm f/2.
It might depend on what you shoot. Even your small samples show some CA - for example, in #5, green LoCA is clearly visible on the top of the tree against the sky.
For people, flowers, and low light, I find that old lenses work pretty well. But for insects, birds, or other things with complex surfaces or sharp edges, I run into issues very easily. And at closeup distances, CAs can ruin shots. 50mm lenses are probably the most reliable, although even they lose some contrast outdoors compared to their results indoors. Many of these issues may not be noticeable at the size at which you shared your images, but I expect my shots to hold up to closer scrutiny. How close?
As close as possible - I had to provide you with this sample if you mentioned peeping
.
I like my old lenses too, but I learned their limitations.

You may get the best out of these lenses on full-frame, but APS-C cameras are really blowing out a piece of their image circle and can expose CA much more clearly than on FF - you can actually think of APS-C sensors as doing the pixel peeping automatically for you.
