Always looking for great wide-angle options for my Hasselblad X1D, I decided to examine the Canon 16-35mm f/2.8 III vs Canon 16-35mm f/4 IS. While I tested them on the Hasselblad X1D, the results will of course apply to FujiFilm GFX users as well, and have been surprisingly interesting.

Both lenses are useable on the 44 x 33mm sensor, with limitations of course, but the Canon 16-35mm f/2.8 III is definitely the most interesting of the two.

I hope you'll find it useful, and I am looking forward to your thoughts. Best regards,

UPDATE - Tested both lens with baffle removed

Upon various forum members' request, I went and tested both lenses removing the internal baffle present in both lenses. I then updated the review adding "no baffle" corner series at all tested focal lengths to check both zoom's behaviour without the baffle on.

In short, removing the baffle makes the f/4 lens usable on the X1D with no vignetting at the long end, and helps with the f/2.8 lens as well. At the short end, there is no difference in hard vignetting coming from removing the baffle; soft vignette becomes softer, but not dramatically so.

The problem, however, is that unfortunately removing the baffle also removes sharpness (from both lenses), limiting their usability to f/8 - f/11 (and sometimes even stopping down doesn't bring enough sharpness back).

For details and images, the link is still https://www.vieribottazzini.com/202...-vs-f-4-on-medium-format-in-depth-review.html

Hope this helps! Best regards
