I wasn't sure whether to post this but given the thred is slow I decided to go ahead.
I bring bad news - my 24/2.8 NC doesn't appear to work well on a full frame IR camera.
Over the years the lens has been one of my go-to optics on my DX IR cameras.
The recent softness in the edges and corners of that shot of Winchester Cathedral spurned me into running off a few brick-wall comparison shots.
Left = vintage 24mm, f/2.8 NC manual focus
Right = 18-35 ED G at 24mm
Bottom = an original view to show where the crop comes from.
Just after getting my Z6 last June I did some color image comparisons between the 24/2.8 NC, the 18-35G and 24-120G. In those, the old MF lens held up quite decently.
IR is a different matter so now I am wondering if the CRC element could be out of whack.
Anyone have any experience or knowledge if a decentered CRC could cause smeary edges?
Another round of experimentation with the Z6 is required but I am sad that the 24/2.8 might get relegated to the bench given the difference in IR image quality.
