Continuous autofocus in video operates quietly but tends to pulse, which isn't unusual. Manual focus for video has its own drawback, unfortunately, detailed below.
If you use manual focus most of the time, the sluggish autofocus doesn't matter. However, it takes at least five partial rotations of the lens ring -- my hand at least can't rotate the ring 360 degrees in one movement -- to go from one focus extreme to the other, and in practice always took more rotations than I felt comfortable with. This is a tradeoff for the fully mechanical lens operation rather than the full or partial servo-mechanical that's found on other cameras. So, not a criticism as much as a warning.
The battery life is rated as pretty short, and seems even shorter with the optional EVF attached. I operated predominantly with the back display set to standard quality instead of high in order to conserve charge, and didn't notice an appreciable difference in the display. (It uses the same display as the RX100.) The RX1 uses USB battery charging, about which I have mixed feelings. It doesn't work with every USB charger -- for instance, it doesn't work with my LG phone charger but it does with a Samsung charger -- so it doesn't always save you from carrying an extra piece of equipment. Plus, since the battery life is short, USB charging makes it difficult to use the camera while charging a spare. You can buy an optional external charger, though.
Design and features
Though reasonably compact, especially for a full-frame camera, the RX1 is no lightweight; at over a pound, it weighs almost as much as some consumer dSLRs. Of course, that's because it's tanklike, made of magnesium alloy. Some weatherproofing would have been nice for the money, though. There's a rubberized layer on the front and back to improve grippability, but a real outset grip would make it a little more comfortable to hold. Sony offers an optional -- and at $250, pretty expensive -- thumb grip (which I didn't get to try), but it looks like the grip covers both the playback button and adjustment dial.
The top of the camera has large exposure-compensation and mode dials, the latter with the usual, including a dedicated movie mode and three custom settings slots. The shutter button has an old-fashioned threaded remote release, and there's a small programmable button nearby. The hot shoe uses Sony's updated multi-interface connection; the pop-up flash doesn't tilt, unfortunately.
On the back, there's an adjustment dial at the top as well as a physically NEX-like programmable thumb dial, plus an AE-lock button and Fn button to pull up all the most frequently needed shooting settings; including some that don't really belong on a camera of this class, like soft Skin Effect, Smile/Face detection, and auto portrait framing. (I suppose you could operate the camera in full automatic if you really want to, but if that's your plan buy an RX100 instead and save the money.) Embedded on the right side is a tiny recessed record button that is difficult to operate under normal conditions and even harder with cold hands or gloves.
The lens has three rings on it: a manual aperture ring with one-third stop demarcations from f2 through f22; a ring with the choice between two focus distances, 0.2m - 0.35m and 0.3m through infinity; and a focus ring. I love the feel of the aperture ring -- it has just the right tensioning and produces the perfect click feel as you rotate through the stops. (It'd be really cool if Sony could figure out a way to make it feel just a little different as you passed through the full stops compared with the third stops.) I wish the lens could focus closer than 7.9 inches, though, and found myself cursing a bit because I was just outside one focus range or the other.
A small, moderately difficult-to-control switch on the front selects between auto, manual, and Sony's DMF (manual focus with automatic prefocus on partial shutter press) focus modes. The camera has tracking autofocus as well, which works out to the edges of the scene.
Despite the aperture ring, from an operational perspective, Sony definitely takes a modern approach compared with the X100S' or X2's completely retro ideal. (The latter two cameras have a shutter-speed dial as well as an aperture dial instead of a mode dial.) So if you're looking for an old-fashioned shooting experience, this isn't your camera; functionally, it has the same interface as Sony's SLT dSLR-type models.

I also tested the expensive EVF -- the optional optical viewfinder is even more costly, if you can believe it -- and have to admit that it's great, if huge. It's especially nice for shooting video. Speaking of video, you can shoot using full or partially manual controls or program. But there's no manual-focus peaking (edge highlighting) in movie mode, which is nuts. I don't mean that there's no peaking while you're shooting. If you're in the movie mode, which you must be in to adjust aperture or shutter speed, there's no peaking.
While there's a full set of manual shooting features, there's nothing above and beyond that, such as wireless connectivity or geotagging. Factoring in the lack of any type of built-in viewfinder, and I find the feature set a bit lackluster for the price; in fact, it would be kind of lackluster at $1,000 less.
If you're looking for the best photo quality you can get in a unibody digital camera, this is it. The Sony Cyber-shot DSC-RX1 delivers a more natural-looking sharpness than even the OLPF-free X-Trans sensor of the and based on my preliminary testing, better color. Plus, the Zeiss lens blows away the Fujifilm's (I haven't seen the Leica's or Nikon's yet). While I'm not crazy about the slowish performance, it's pretty typical for these types of cameras, regardless of price segment.
That said, if you want a great "compact" and still want money for food, unless you're really picky the APS-C models are still an excellent choice.
(Shorter bars indicate better performance)
