I am in the process of filling a "gear gap" and the current short list (still in flux) has come down to two cameras. I have the dSLR and film (35mm / medium format) covered and looking for a small digital to carry to dinner / social events including photos of food, wine labels, etc.
The LX100 is about 1/2 the price, but both are reasonably positioned. The LX100 seems a little small in my fingers, and I can live very nicely with the fixed 35mm equivalent lens of the X100T. My intended usage would be in-camera jpgs more so than RAW. Of course in black ; ).
Face recognition with the X100T would be an advantage for quick restaurant shots in darkened rooms with friends. Both are listed as 50cm close focus and macro at 3cm - LX100 / 10cm - X100T, about equal for my needs. For 'serious' macro (do I shoot serious macro) I would use the 5DII.
X100T: ergonomics (small but not too small), low light ability, hybrid finder system with the choice of optical, ND filter build-in (useful on bright / snow days), flash, quality of in-camera jpg.
LX100: a bit faster f/1.7-2.8 (vs. f/2 for the X100T), better macro ability (with closer working distance), price, zoom (24-75 35mm equivalent) vs. fixed lens, excellent sharpness.
I would like to hear your thoughts on the two cameras and/or other options based on my requirements.
