My beloved X100 classic began having worsening troubles with its power switch over the months since last October when it fell over on a tripod. When I could no longer reliably power it on or off, I got the X100F.
Fujifilm is no longer repairing the X100 classic or X100S models. They no longer have parts. I got this info directly from the east coast US Fujifilm repair phone number.
I had been shooting a lot of infrared with the X100 classic through a Hoya R72 filter.
I could shoot handheld with ISO 1600, f/4.0 or 5.6 with shutter speed of 1/15 or even 1/4 second.
I found that the X100F doesn't have the same capability. I was having to bump the ISO to 3200 or higher.
At 1/15 or 1/4 second sharpness was hit or miss.
While I really like the X100F image quality other than through the IR filter, I missed the ability of the X100 classic to shoot that IR so much that I purchased a used one from
B&H.
The image quality of the X100 classic still compares well to the image quality of the X100F. I have not noticed a decrease in the X100F quality by choosing to shoot compressed raw rather than uncompressed. The file sizes are more manageable in Photoshop.
So therefore, my advice would be to stick with your X100T until it no longer operates.
