Re: 17 mm shows 19mm in EXIF on 17-40mm f4

I don't have one to compare, but I've seen countless images with the correct 17mm value in the EXIF, and I've never seen this issue reported so I don't think it can be a common problem.

So something is out of alignment. If it's an old lens bought used, maybe it has been repaired and reassembled incorrectly. I once bought a used lens (not a 17-40) from a reputable source, which had clearly been wrongly assembled.
