I currently own the 85mm F1.4D, and everyone seems to hold this lens in high regard in terms of quality, but I'm slightly baffled by this. I honestly don't believe the quality is actually that good, and the amount of purple fringing I've noticed on photos since I've owned it, really deters me from using it at all. The AF isn't particularly great on it I've found, even on a body such as the D3. The 1.4D was used for indoor sports, which it wasn't really designed for, but the light in some of the indoor arenas that I've taken photo's in has been really bad. I was usually shooting at F1.8 on my D3 at 6400 ISO with 1/250 sec shutter speed!
All of this has got me thinking. In an ideal world, I'd buy the 85mm F1.4G probably, since it's apparently fixed most of the issues I have with the D version.
But the G version is pretty expensive, so I was thinking, would it be worth selling my 85mm F1.4D and buying the 85mm F1.8G. Is the G version going to be better quality than the 1.4D?
The bokeh on the D version was actually very good, so I can imagine the 1.4G being even better, but I feel my money is best placed in other lenses at the moment.
The lens would be used in conjunction with a Nikon D4s.
Any advice would be greatly appreciated.
