Some Teasing: Fujinon XF 16-80mm f/4
#1
Well, I am terribly sorry, but I'm afraid I need a few more days to publish the review. Because:

  • I'm really out of practice Wink
  • for several days in a row now I haven't seen much else other than the test chart, Capture One, Imatest and Excel and I really need a break
  • Since my last review, basically everything is new: new cameras, new charts, new software. All or most of the work to set up everything is done, but one thing I completely underestimated is: none of the templates I used in the past can be reused. So, for the first few reviews, I'm basically starting from scratch for most charts and images.

However, a few facts in advance at least:

I guess no one really expects a consumer zoom (and that's what the XF 16-80 in my opinion is, even with its high price point) to be stellar. Still, the lens has some surprising negative sides.

Vignetting, for example. At 16mm wide open, it exceeds the scale of our chart by a full stop, reaching 2.5 EV.

And then there is distortion. You could see it in some sample images already: pronounced pincushion distortion for most of the upper zoom range and hefty barrel distortion at 16mm.

'Hefty' in numbers means: 5.36 %

Of course there is software correction, and if you shoot JPG or use a 'Fuji friendly' raw converter, the actual distortion will be hidden (as the camera hides it by default in the viewfinder and on the rear display).

But software correction takes its toll, in this case it's a whopping 20% resolution in the image corners.

Just the corners, though, the effect of the auto correction is a lot less pronounced at the image borders and of course basically zero at the image center.

As mentioned already in a different thread, I will provide MTF charts for both native lens performance and autocorrected (with correction in Capture One).
