Fuji X-T3 File Resolution larger than sensor size
Hi guys,
I've noticed an interesting phenomenon when using Capture One for Fuji with my Fuji X-T3 and my Fujinon 10-24 f4 lens and Fujinon 18-55 f2.8-4 lenses. The RAF file resolution when displaying is the standard 6240 x 4160 px. However, when I click the Crop function, it appears as though the file has been automatically cropped. When I expand out the crop to include the extra region, Capture One enables me to get a file resolution of varying sizes (Most common size says 6533 x 4233 (with my 10-24), but sometimes up to 6599 x 4284 (with my 18-55.)) Has anyone else encountered this situation. I believe this is a software error with C1 as I seriously doubt that Fuji will have given us a sensor that is actually bigger than what's been publicised. But maybe there is a more nuanced answer that I don't understand.
Thanks guys,
Jonathon.

It is not a software error. What it will result from is automatic lens correction applied by Capture One. If you go to the lens tab, and the Lens Correction tool, you could pull the distortion slider down to zero and see the cropped off area magically disappear. It will vary from image to image with a zoom lens because the distortion, and the correction needed, is greater at wider focal lengths. If you don't want this to happen, you can click the ... in the lens correction tool and and select Disable Default Lens Correction.* But most of the time it is probably a good thing to have the correction. I usually leave it alone, except very occasionally when I could do with a few more pixels at the edges because my wide angle was not quite wide enough.
Why worry? You are being delivered 6240 x 4160 pixels, which is what you bargained for. (I am not 100% sure how it works, but I wonder whether in fact cameras do collect slightly more pixels than the nominal amount, but only deliver an image of the nominal dimensions. After all, if you got the camera to record a JPG instead of or as well as a raw file, it would probably apply some lens corrections and it would have to have some spare pixels to play with to do that.)
* Checking that option will only affect new imports, not existing ones.

Hey Ian,
Ah, that makes a lot of sense. Thanks so much for your informative response. I hadn't given lens correction a thought. I wasn't complaining that there are more pixels than expected, but I was really curious as to if/how that could be the case. Thanks for solving the mystery. Merry Christmas
