Having owned both, I can tell you the 85L and 85/1.8 have about the same CA at the same apertures. The 85L has no CA advantage over the 85/1.8.

That sucks, maybe my copy was worse than normal. I also did not go out of my way to avoid situations that make it worse. Nobody ever talks about it on the 85L I still would like to have one and see for myself.

I'll play: I think B is 85L. A shows some vignetting (and a tad underexposure), B has slightly better bokeh, and is sharper.

Kind regards, Wim

I'd also like to see the same shots with the subject closer to the edge of the frame. This is where the 85/1.8 should clearly win. Who shoots with the subject dead centered in the frame, usually.

If shoot at the same @ f/1.8, 1/20s, and the same ISO, the same spot with tripod; how come Test A is darker and crop bit tighter?

If A and B is set to the same exposure, and lens B gives me a brighter exposure, I'll take lens B. :)
If lens B is in fact the 1.8, I'll switch.
If B is L, I'm happy with my decision and withdraw my mind about getting rid of it.

Because A shows some vignetting, possibly because it is closer to wide open, and because the FLs are not exactly 85 mm :D.

Kind regards, Wim ;)

Well, how do they measure camera to subject distance?
The lens tip of the 85L is sure longer than the 1.8.
So the 1.2 will be nearer to the subject.

LLFL,
Mind doing both at f8?
Thanks in advance!
But don't tell which is which. :)
I get biased when I know which is which.

Not to be a pain but this would have been more interesting if shot with a FF where the differences might be more apparent. Personally I think a lens like the 85L is, somewhat, wasted on a crop sensor. I say that, because people generally buy the L for it's thin DOF. To handicap it on a crop seems to be money not well spent.

Is it distance to sensor? not the front of the lens element? Then lens size doesn't matter

So the 1.2 will be nearer to the subject.

Camera/subject distance is exactly that: from sensor to subject.

If the FL of the 85L is a little less than 85 mm, it may well show more in the frame (or vice versa).

FLs generally are nominal values only, unless specifically indicated, like Leica did on some on their lenses (individually, up to 0.1 mm accuracy), and Pentax did with their special edition lenses (still nominal though, although more restricted, see below). It is considered acceptable to round the FL within 5%, up or down. IOW, 85 mm may be anything between approximately 80.5 and 89.5 mm, which is more than 10 % of a difference, potentially, between two lenses which are nominally 85 mm.

BTW, not even two lenses from the same production line, same model, have exactly the same FL - even those may vary within a few mm (as those individually marked Leica lenses did show, f.e.).

HTH, kind regards, Wim

There really is nothing in those samples to decide one way or the other. One reason I hate these type of comparisons. I would prefer, and I know it requires a lot more effort, shots more typical of how the lens would be used, or shots where the differences can be clearly shown.

Yes, that is how it is measured. The point from which it is measured is marked on the camera, that's the little o (or circle) with a line through it. Approximately anyway.

Kind regards, Wim
