All things considered it feels comfortable shooting with the XH A1; though it weighs almost five pounds, it's still considerably lighter than most. All the buttons and controls sit in logical locations, grouped roughly by function and generally in the same locations as they appear on competing models. They're good sizes, and various bumps and divots in the buttons provide enough tactile feedback to operate without looking. A large chunk of the camcorder's architecture lets you determine the speed and subtlety with which shifts occur during shooting, including focus, zoom and exposure changes, and white-balance adjustments. (For a complete discussion of the controls, click through the slide show.)
On the lens barrel, rings of different sizes and textures operate focus, zoom, and iris. In response to complaints about the mushiness of servo-controlled focus, Canon offers a Slow speed option; that option, plus a distance readout help to maintain a finer control over focus response, but you'll probably still want to try it and compare to others if you're picky about the feel. I think it feels about the same as the Panasonic AG-HVX200's.
The same three 1/3-inch CCDs with 1080i (1,440x1,080) native resolution that drive the XL H1 sit at the center of the XH series' imaging system, and like the H1, both models can record in 1080i at 30F or 24F frame rates. The latter comes in two versions, one which records to tape at 24 frames per second, and one which downconverts from 24fps to 30fps/60i using 2:3:3:2 pull-down before recording for greater editing compatibility. Their feature sets share many of the H1's technologies, including a Digic DV II processor, Super-Range Optical Image Stabilization, and the H1's customization architecture. The XH cameras have fixed 20x zoom lenses rather than the interchangeable lenses on the XL, but they offer a wider-angle view: 32.5mm-to-650mm equivalent.
The lens and focusing system perform very well. The lens displays very good edge-to-edge sharpness, albeit with a tendency to display a bit of magenta chromatic aberration on the sides, and the center focus looks great, especially when zoomed in tight. As usual, Canon's optical stabilizer works exceptionally well, even all the way out to 20x.
With Instant AF enabled, the autofocus works quickly, and the Push AF, which activates an Instant AF override in manual-focus mode, speeds manual focus considerably. As noted in the XH series' documentation, there's a bit of an autofocus lag in 24F and 30F modes; it's perceptible, but if you shoot a lot in those modes and use AF, your shooting rhythm should adapt after a while. Canon moved the Peaking and Magnify focusing aids out to the body of the camera--they were in the menu system in the XL H1--and you'll rely on them pretty heavily; the tiny, low-resolution LCD is pretty difficult to work with.
