Fujifilm has just announced the new X-E1 mirrorless camera, which is a smaller sibling to the successful X Pro-1. It features the same 16.3 mp CMOS sensor as the X-Pro1, but has a smaller and lighter body.
It features a 2.8-inch LCD, a pop-up flash, ISO of 200-6400 (expandable to 100-25600), and RAW and built-in RAW conversion, but doesn't have the hybrid viewfinder found on the X Pro-1. It only has a EVF. It's much lighter than its larger sibling, and in terms of size, it's 30% smaller.
I haven't used my X Pro-1's video mode (relying on the Canon 5D Mark 2 when I needed to) but the X-E1 can shoot 1920×1080 video at 24fps, and Fuji's Film Simulation option can be enabled during video recording...nice!
I leave it to you to decide if the X-E1 will be as successful as the X Pro-1. My initial reaction is that it might be too small...even for a second body. However, it's supposed to have a retail price of $1000...$700 cheaper than the X Pro-1.
