Ah, what a painful paradox! Fujifilm x100t is a small, beautiful camera that can take great photos but is incredibly frustrating to use. Its user interface is inscrutable and opaque. I feel old and crummy using this camera. The camera fees like an adorable petulant child and I already have one of those and cannot deal with another in my life.

Having heard raving reviews of the predecessor X100S - I pre-ordered the T. I really really wanted to like it, I know the Internet generally loves this camera. However, after using it for almost a year and having taken some decent shots with it (samples below), it is still far from being a "go-to" camera for me. I'd still pick the old reliable 5dm3 over it any day even though its heft has lately been killing me.

Here are some quick notes on what I like and what I don't.

What's to like?

It is really small and looks really great in a cool retro way that will definitely make people notice and take you for a hipster film-shooter
Image quality is often excellent, if you can actually get it to do what you want. Sample photos are posted below.
Physical dials (instead of on-screen menu options) make it easy to change key settings like aperture, shutter speed, ISO, etc.
A nice option to delete multiple shots together.
Ability to control dynamic range selectively via a menu option is nice
Decent support for auto-ISO with minimum shutter-speed range

What's not to like?

The physical dials are easy to change by mistake leading to ridiculous settings and ruining photos. The dials have a tendency to change when in your bag or around your neck if you bump into things
Every time you pick the camera to shoot - you have to check to make sure settings look ok
The viewfinder is tiny, dark and seems to have a mind of its own. It is easy to go into weird modes where only a part of the scene is shown in focus, or the on-screen menu starts to show up in the viewfinder or you get a little box overlapping your original image. It is just baffling - more so because switching from one mode to another is often accidental and unintentional
Switching to fulltime EVF (electronic view finder) kills the battery and the shots look weird. Guess I am just not comfortable with an LCD in the viewfinder.
Takes time to recycle between shots. There doesn't seem to be a way to shoot continuously. Except a very strange mode where the camera seems to take multiple pictures but stores only one blurred copy. I am sure there is a good reason to have this mode but I could not figure it out. Getting out of this mode took me weeks. I think I had to reset the camera to factory settings.
Battery life is terrible. You barely get a few hours and that is if you don't much use the electronic viewfinder or the screen at the back.
The battery charger doesn't have a built-in plug - requiring a huge, thick additional cable to carry. The cable is truly ginormous.
The battery goes in either side but only one side actually works :-(
The option to connect with an iPhone app for geotagging and photo view is laughably bad.
Low-light performance is decent but not great - partly defeating the purpose of a small camera that you want to carry everywhere with you
Raw files are pretty large for 16mp. They are in RAF format and Lightroom takes much longer to process these than processing 22mp files from the Canon 5dMiii. Not sure why.
It can presumably take videos - though I haven't been able to easily figure out how to get it to do that.
At $1,300 it is hard to justify as a part-time toy

(the photo above, was taken with the x100t is from Week #280 of the 300-week photo project)

Some sample photos are below

Featured

Portraits in bright light are crisp and clear - as good as any DSLR

Focus is generally pretty sharp

Indoor shots can be pretty sharp and clear

Shots can have decent dynamic range even in high-contrast shots

Simple indoor shots are warm and nice

the f/2 lens offers pretty good depth-of-field and clarity

The small camera is well-suited for street photography, as long you are careful about confirming the settings don't change in accidentally.

X100T can capture colors quite nicely I think specially in bright lights. I find it a little bit partial to blues though.

X100T can capture decent details in harsh sunlight exhibiting decent dynamic range.

Planned action shot. Notice the decent details in the mountains and clouds in the background.

Relatively tough scene to shoot but the camera did a surprisingly good job with DOF

The wide lens (23mm/35mm equivalent) allows for decent landscape shots. Notice the detail all the way in the background across the Meteora region in Greece.
