Edit [30/6/13]: Rico added several SOOC JPEG portrait samples taken with the X-M1 and the two new lenses to his Flickr set. Check out his in depth first look of the X-M1 here (added his experiences using an USB adapter to get RR-80 remote controls to work with the X-M1).
Matti Sulanto just posted his first impressions of the X-M1 (pre-production), 16-50mm and 27mm at his website here. Among the other he says that:
“[X-M1] The Fuji X-M1 is very small and probably one of the smallest APS-C size system cameras. […] I saw the first pictures of the X-M1 some weeks ago and I was not impressed by the rear control dial. But, as they say, never judge a book by its cover. Now that I have used the X-M1 a bit, I’m rather happy with the control lay out. […] Shooting with the new Fuji X-M1 is a good experience. The autofocus is fast with the new 16 – 50 mm and the 55 – 200 mm zooms. Not E-P5 fast, but fast. […] The competition is tough in the middle class of compact system cameras, but I think the new Fuji X-M1 stands a fair chance. […]
[XC 16-50] Even in its pre-production form this lens looks as good as the rest of the Fujinons. […] The zoom ring rotates smoothly and the lens extends to almost double length when zoomed from wide to tele. […] The optical performance looks promising, but I’ll wait until I have a real production lens, until I draw my final conclusion. The autofocus is fast and the OIS seems effective. I managed to get sharp pictures at 1/2 s. shutter speed at 50 mm setting, when I concentrated a bit.
[XF 27mm] It is quite small and light, but seems well constructed. […] The autofocus is fast, but makes more pronounced back and forth movement and little more noise compared to the 16 – 50.”
