Hi,

Most of us don't own both 23mm lenses, but side by side pix posted online have allowed us to observe that the XF23/2 is slightly but noticeably wider than the XF23/1.4. I've never seen a lab test or post which has actually measured its FL to confirm. (It may be that the 23/1.4 is slightly longer than 23mm.) There's also little point in comparing the FOV with an FF 35mm because their FLs often vary a bit each way too.

Personally, I wouldn't worry too much about it. The difference is small and it's 'in the ball park'. Choose the lens that best meets your preferences on all the other information.

Cheers, Rod

People did the same test with a 23mm f2 vs 18-55mm and they came to the conclusion that the 23mm f2 is somehow 21.5mm.

Which is a good slight advantage for landscape shooters like me, sometimes this slight 1.5mm can embody an additional subject like a tree

Edit: Found the original comparison photos of 23 f2 vs 18-55 at 22.8mm
