DPReview published a list of 5 reason, why Fujifilm won’t make a full frame X100 camera.
A larger sensor would add size and weight, mitigating a major X100 selling point
Such a product would cost a lot to develop and manufacture
The result would be a very expensive camera – reducing its potential audience
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
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.
Some Fujifilm X100V users over at our 30,000+ members strong Fujifilm X100V facebook group are experiening overheating issues on their Fujifilm X100V camera. The affected area is the entire lower back of the camera, as you can see from the image above. You can read the post about this issue here.
Other members do not have this issue, so maybe it affects only a limited number of cameras that might require an extra step at the Fujifilm service for a fix.
In the video below, Andrew tested the X100V overheating. Here are his findings:
camera set at 3 seconds interval time shooting
after 600 shots the camera reached 108 Fahrenheit (42 Celsius)
temperature remains steady also after 750 shots (on same battery)
Heated Room Temperature (ambient temperature at 100/105 Fahrenheit = 37/40 Celsius)
camera quickly arrives at 100 Fahrenheit around thumb rest area
after 100 shots he reached 114 Fahrenheit (45 Celsius)
only after 600 shots he got the yellow overheating warning icon (129 F/ 53 C)
after that things remain steady and the camera didn’t get much hotter
yellow overheating icon you can still shoot, but you risk more red hot spots
once the overheating icon turns red, the camera is about ti shut down
CONCLUSION for STILLS
In real world photographing there is nothing to be concerned about
In video, after 12 minutes he got overheating warning and temperature climbs quickly
if you swap the batteries, you can record also over 1 hour
you will indeed get overheating issues if you shoot longer 4K videos
Also, in the video below Andrew reports about flaws with the focusing ring, which some report gets an unpleasant grinding when you turn it. Andrew has in general experienced this kind of sound also with other Fujinon prime lenses. He said he heard Fujifilm is quick in fixing this. The X100V he has, has not this issue.
