Thought I would write a 'mini review' which may help others decide about buying the XPro.
A bit of background, I have been with Nikon throughout my DSLR life, and have a D700, D300 as well as a couple of primes and the 'pro' 24-70 and 70-200, so used to good quality IQ and glass. I also dabble a bit with film cameras. The XPro was bought for 2 reasons... I wanted something more compact and didn't like compacts, and I loved the look (this was to replace my Leica M2). Initially, while I liked it, I had some doubts, as IQ on the 18mm was not as good as hoped, and the AF was poor (compared to the D700).
I have not done too much photography since I got this, so the short bursts I had with it was me still getting used to it. I took it down to London the other day for a few shots in and around work, and then a day at Duxford. Just imported them in and i know know that this is a keeper (until the XPro 2 comes out!!!). I took the D700 with me to Duxford too and really did notice the size and weight difference, its perfect. It looks great and is great to hold. It does take some getting used to when coming from a DSLR though. It is slightly slower, and the AF is not as good. However this is not a huge issue, once you get to know the focusing it becomes second nature. It is quick enough in most situations, but my DSLR will always be 1st choice for action stuff!
The 18mm is not the sharpest wide open, yet stopped down a tad it is very good (not used the 35mm as much but that is a belter!). This image is SOOC at f4 (800ISO).
While I shoot RAW 100% of time on Nikon, its JPG all the way on the XPro. Most JPGs need minimal tweaking and the IQ on my screen is no different to the D700. Ok, if I pixel peep maybe the D700 and prime may edge slightly, but the difference is VERY fine. The ISO performance is very good too - 1600 is fine and better at 1600 than the D300 at 800ISO!! In fact, at 3200 I have a feeling (could be the Fuji JPG processing) that 3200 is slightly better than the D700.
Good Points - Looks, size & weight, how it feels to hold, ISO performance, controls, IQ, JPG processing, general speed (menus, start up etc...)
Not so Good Points - Battery life (compared to D700), having to press AF button to change AF point, no general AF auto detect like on D700, for fast moving kids it is not as good as the D700.
Overall... even if you are coming from pro type bodies and glass, I don't think it will disappoint. There are some things I think the XPro beats the D700, and vice versa - it does take a little practise to get used to it but after that its a great camera. If you are in a studio, or shoot fast moving kids all the time, then a DSLR does have some advantage but for general family/kid shots and anything else (landscapes, general stuff) its lovely. If you are thinking of getting one, do so!!
There are a few tweaks I would like to see in a new body or firmware/hardware:
- Auto AF Detect (and/or face detect) - Better small tilt flash - ability to move AF points without pressing AF button (like on a dslr) - better battery life.
