Excerpt: I use X-M1 with 27 mm lenses more than one month. Prefer film mode natural+sharp=+2, frame size 1x1, auto ISO, S priority. Forgot about flash. Almost perfect, first class camera. Nikon and Cannon lost market. X-M1 is not so perfect like Sony Rx1R, but better than any other competitors. If you have no money for Rx1R, buy X-M1 + 27mm, no choice. Do not buy zoom lenses. Closest competitors: Leica X-Vario and Olympus D-5 - have nice picture but noisy on low ISO (sensor).
Excerpt: I have been playing with the X-M1 for two days, and so far I love it. The colors are superb (tank you Fuji), and the noise is not a problem up to ISO 6400. My only issue so far is the fact that the included RAW converter (Silkypix) can't duplicated the camera JPEGs (colors and contrasts don't match), but the in-camera's RAW converter can, although it's an hassle to have to proceed that way.
Summary: I have used Canon DSLRs for years but got tired of waiting for them to produce a decent compact system camera. But having spent a while looking for a small lighter camera with a large sensor I decided to get the M1. I had reservation about buying a Fuji as I have not used their equipment before, and the M1 in particular as it does not have a viewfinder.
Summary: Great sensor, kit lens is good outdoors but not great inside as its a bit slow. Flash is useful as it can be bounced up/ backwards. Fantastic sensor. Autofocus is fine for subjects that are not moving. This camera is transformed with any of my 14mm, 18mm, 23mm, 27mm or 35mm lenses. I'd recommend the 27 or 35 with this camera especially the 35 for the combination of cost, sharpness, low light ability (f1.4), size, and being able to change aperture with the aperture ring.
Summary: So far I have had only limited use of the camera but the image quality from the 16-50mm. kit lens looks very good. 4 stars only as of course there is no viewfinder but the articulated screen helps make up for that. I was driven to purchase this as my son has X-Pro and X 100 and I already have X 10 - all excellent cameras. I have a DSLR but for travel/walkabout photography I think I will get more use out of this.
