Five Reasons Fujifilm Won’t Make a Full Frame Fujifilm X100

DPReview published a list of 5 reason, why Fujifilm won’t make a full frame X100 camera.

  1. A larger sensor would add size and weight, mitigating a major X100 selling point
  2. Such a product would cost a lot to develop and manufacture
  3. The result would be a very expensive camera – reducing its potential audience
  4. A move to full-frame would annoy and worry existing loyal Fujifilm APS-C customers. Also, if Fujifilm announces any full frame camera, could look like a massive vote of no confidence in APS-C
  5. The risk of cannibalization within existing lineups is too great

And what about a medium format X100 then? DPR writes:

So might Fujifilm build a medium-format X100? There’s an argument to be made that it makes sense in a way that full-frame just doesn’t. Medium format would offer an increase in potential image quality over full-frame (albeit relatively modest – about 2/3EV), a significant leap in image quality over APS-C, it’s a major part of Fujifilm’s brand identity, and the larger format is a key differentiator for Fujifilm compared to competitive manufacturers.

Well, I won’t enter the argument about the “relatively modest” advantage of the Fujifilm GFX over full frame. This is a thesis DPR started pushing back in 2017, and FujiRumors comprehensively answered it in the article “DPReview Recommends 3 Full Frame Cameras Combined over 1 Fujifilm GFX“. Also, in the meantime something called Fujifilm GFX100 hit the market, with the newest sensor technology.

For the rest, the whole 5 reason list makes sense. Check out the full in-depth article at dpreview.

And one could also add one more ;)

  • full frame offers a “relatively modest” advantage over APS-C, and also has a couple of disadvantages over APS-C, that you can read here

Popular photography industry insiders, claimed that APS-C is the actual sensor size sweet spot. Keep in mind, they said “sweet spot“, not “automatically the best tool for everybody“.

Laowa 15mm f/4.5 Shift Full Frame Lens on Fujifilm GFX – First Sample Images

Venus Optics will soon launch the Laowa 15mm f/4.5 W-Dreamer shift lens for full frame cameras.

Now we have some sample images and we can give a few more details about how this full frame lens works on the Fujifilm GFX medium format system.

According to a beta tester, the Laowa 15mm f/4.5 W-Dreamer shift lens can be used on Fujifilm GFX, but the ability to shift is limited to ± 7.

Here is his the feedback the Chinese beta tester gave so far:

Although the image field of the shift lens is much larger than the ordinary 135 format lens, if the offset is too large (± 7 or more) on the 44×33 format, it will still have a dark angle

@ 老 frog lens 15-axis image field perfectly covers the 4433 sensor, visually there is 5mm up and down, and 3mm left and right shift amount

@ 老 frog lens 15-axis transfer to Fuji GFX 50R, the picture quality looks pretty good, even if it is an ordinary ultra-wide-angle lens, the perspective is very strong. Blessed 4433 users
