>>2891793If you're looking for the self timer, that's not what T is for. Self timer should be in the drive mode settings, if I'm remembering right. (I sold my X100 a while back, when I bought my X-Pro2.)
T is for setting shutter speeds that aren't on the dial, mostly stuff over 1 second. You put the camera in T and then flick the little thumb wheel back and forth. If that's actually what you're trying to do, and it's not working, I don't know why that would be the case though.
>>2890706As an X-Pro2 owner, I wouldn't really suggest it to somebody who wants something like an X100. The body alone is much taller and wider than the X100 and almost as thick, and putting a lens on it makes it way too big to stick in a coat pocket or whatever. It's a great camera, but it's a DSLR replacement and intended for more "serious" use, not a "take it everywhere" camera like the X100.
