I wanted to ask this here as most of you are fans of the X100 series. I have an X100T and I like it, but I'd like it more if it had the updated AF of the X-E2 and had a 35mm lens. As I don't shoot with flash, does the leaf shutter really matter? Any other advantages of the X100T? I have an X-Pro2 on preorder and a 35mm f/2. I'm thinking of selling my X100T and using the X-Pro2 with the 35mm. As far as focal lengths, I have them all covered already with my X-T1. Basically I just don't know if it makes sense to hold on to the X100T.
One of the advantages of the x100 series is the leaf shutter. Because there is an "all open" state for any aperture (to a point) you can expect to shoot with a shutter much faster than the typical sync speed of a focal plane shutter. My experiment has the x100s in manual exposure and the flash set to manual power. I understand that success with fast shutter speeds may require a direct wire connection between flash and camera, radio transmission having internal transmitter/receiver delays that cause the flash to fire after the shutter is open for fast shutter speeds. I verified this with a Cactus v4 system and the Nissin i40. I had success at shutter speeds up to 1/500 s, but by 1/1000 s the flash pulse mostly occurred after the shutter closed. The flash part of the exposure dropped significantly at the faster shutter. I duplicated behavior if I used a Canon compatible ttl cable connecting the two. Somewhere faster than 1/500 shutter the flash exposure drops significantly for apertures f/2 and f/4. Having failed with Nissin i40 I substituted a Nikon SB 700, another smallest flash that would fit in my bag easily. It worked at shutter speeds up to 1/4000 s for both f/2 and f/4 apertures. My guess is that the Nissen flash has a slight internal delay that causes it the fire after the faster shutter. I attach two files, the i40 flash at 1/1000 shutter showing the flash did not illuminate the subject, and the Nikon SB 700 at 1/2000 shutter showing the illuminated subject against a dark background (outdoors).
