Having had some more time with my X-M1 I thought I would write a bit about my experience switching from an SLR, Canon 30D in my case, as others may be considering the same.
One of the biggest differences is the physical size. I've been using the 35mm f/1.4 exclusively and whilst it's a chunky combo it's so much more portable than an SLR and importantly less obvious. It will fit in a jacket pocket which means I don't mind carrying it around.
The image quality is really superb, the 35mm is a cracking lens, sharp across the frame wide open and the high ISO performance is still impressing me but then I'm coming from a very old body. Compared to the Canon files I'm used to the Fuji just produces a really nice tonal quality and you don't get the horrible colour noise and banding in shadows.
Other things I'm finding really useful are Auto ISO, setting max ISO and minimum shutter speed and away you go in aperture priority. The manual aperture ring I'm also loving. The flip out screen allows you to do really inconspicuous street photography and take shots I wouldn't have normally thought of.
I do miss having a view finder, I would like to have a go with an X-E1/2 or X-T1 and may add one of these to the lineup in the future. Whilst the auto focus is good and certainly fast enough for day to day shooting it's not as intuitive as my 30D was but it is accurate. It also absolutely sucks at focussing on stuff within 50cm unless you specifically put it in macro mode which annoys me.
Something that has surprised me how much I've used it is the ability to quickly send photos to my phone over wifi, it's brilliant for messing with photos on the fly for emailing and instagramming. Overall I'm really pleased I made the switch. I haven't spent any time with the kit lens or shot any landscapes so look forward to see how it performs.
