The HV20's rear-mounted joystick is great for one-handed operation
The HV20 allows independent control over just about everything except for gain, in its Recording Program modes. Pressing the function button, and selecting the icon at the top left corner of the screen allows you to choose from Program AE, Shutter Priority, Aperture Priority, or Cine modes. In all these modes, it is possible to fine tune exposure by pressing the joystick once, to bring up the Set display in the lower right corner of the LCD. Manual exposure (in EV steps) is the first option in the Set display, while tapping down moves through the Set menu pages (Mic levels, and End Search). The HV20 adds two modes found on the company’s prosumer camcorders, like the XL 2S and XH A1 (Specs, Recent News, $3279.99): In Tv, or Shutter Priority. In Av, or Aperture Priority mode, you can set the aperture manually while the camcorder adjusts shutter speed. In Av mode, the shutter speed will not drop below 1/60 unless Color Slow Shutter is enabled.

The HC7's Cam Control dial in all its miniscule splendor
Unfortunately, the camcorder has what many experienced shooters will consider a fatal flaw: a Cam Control dial that is so undersized that actually making adjustments quickly is difficult at best. The dial on the HDR-UX7, Sony’s top AVCHD camcorder is bigger, and easier to use, while the Cam Control ring on the HDR-SR1 (Review, Specs, Recent News, $1119.99), Sony’s HDD-based AVCHD model, is best of all.

The SD1's back end is where the manual control action happens
The joystick-centric manual control suite of the HDC-SD1 carries over from Panasonic’s standard definition consumer line, and using a joystick to focus standard definition video is doable. The joystick on the HDC-SD1 is also a bit more difficult to operate than the ones on its standard definition predecessors. The new controller feels like a higher-end implementation, but we found that we couldn’t navigate up, down, left, and right with the facility we’ve grown to appreciate on consumer Panasonics.

The HD7's rear controls and LCD joystick
Despite this omission and some other quirks and minor annoyances, the HD7 has an excellent suite of manual controls that rivals or surpasses the Canon HV20 and Panasonic HDC-SD1 in terms of interface quality and efficiency. The Sony HDR-HC7 tops the field in terms of number of controls and control settings and includes a LANC jack for remote operation, but its Cam Control multifunction dial is so small that manually focusing with accuracy and speed is nearly impossible. Add in the HD7’s large, comfortable hand strap, a large removable lens hood, very good OIS, great balance, and an excellent eyecup, and the HD7 punches above its class in a way that only the Sony HDR-HC1 (Specs, $2295) matched in recent memory.

The HV20's pint-sized, underdeveloped zoom lever
Sony HDR-HC7 – The Sony HDR-HC7 features a primary zoom control with a rocking lever design, a set of secondary zoom buttons on the outside of the LCD frame, a remote control with zoom buttons, and is the only camcorder among this group to include a LANC jack for remote wired operation. The zoom lever is excellent, and offers slightly more leverage and fine control than the others because it's larger and taller. The difference may seem insignificant (and the levers on the JVC and Panasonic are nearly as good) but zoom is an important enough control for us to praise Sony for making consistently excellent zoom controls. The LANC jack is another nice inclusion, and makes this the camcorder of choice if you need a camera B for boom shots.

The HC7 sports a stellar zoom control
Panasonic HDC-SD1 – The Panasonic HDC-SD1 comes up short in the zoom department, with only one on-camera zoom control, the rocking lever on top of the body. The control itself is very good, but the option of a secondary control would have been a welcome addition for those high- and low-angle shots that render the primary zoom toggle difficult to use. Like the other camcorders in this article, the SD1 includes a remote control with fixed-speed zoom buttons.

The SD1's zoom toggle
JVC GZ-HD7 – Like the other camcorders in this piece, the JVC GZ-HD7 features a zoom control with a rocking lever design. It’s positioned well for use during hand-held shooting, and allows for good control throughout the range at variable speeds. The JVC lacks a secondary LCD-frame zoom control like the Panasonic, but does include a remote with fixed-speed zoom buttons. On a camcorder that aspires to bridge the consumer-prosumer divide, we would have liked to see a LANC terminal or at the very least a secondary zoom control.

The HV20's focus dial

The HC7's Cam Control dial
Panasonic HDC-SD1 – The Panasonic SD1 includes a Focus Assist feature, but it’s not as good as the one found on either the HV20 or HD7. In addition, this Panny is the only camcorder in this article that does not include some form of rotary focus control. Instead, manual focus is controlled using the joystick on the back of the camcorder body. Unlike a rotary control that can be nudged ever so slightly to fine-tune focus, the joystick is an electronic control that pulls focus at a fixed speed. The motors that move the lens elements are either moving (when you nudge the stick) or not, so fine-tuning is a matter of making very quick taps as you approach – and attempt – to get a sharp picture. Yes, it works, but the JVC and Canon do manual focus a whole lot better.

Canon HV20 - In Tv (Shutter Priority) mode, the HV20 includes a range of settings that vary depending on which standard you're recording in. For 1080i, the shutter speeds available are 1/8, 1/15, 1/30 1/60, 1/100, 1/250/1/500, 1/1000, 1/2000, and in 24P they change slightly to 1/6, 1/12, 1/24, 1/48, 1/100, 1/250/1/500, 1/1000, 1/2000. Canon also lists shutter speed settings for memory mode (an option for recording low-resolution video to Mini SD): 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/100, 1/250, 1/500. The ability to drop the shutter speed to 1/24 in 24p mode gives this camcorder very good low light capabilities - and that made a big difference in our tests where the Canon's 1080i low light performance equaled the HDR-HC7's, while 24p bought the Canon 4 lux.
Sony HDR-HC7 - The Sony HDR-HC7 features the widest shutter speed range of this group, in the following values: 1/4, 1/8, 1/15, 1/30, 1/60, 1/90, 1/100, 1/125, 1/180, 1/250, 1/350, 1/500, 1/725, 1/1000, 1500, 1/2000, 1/3000, 1/4000, 1/6000, 1/10000. The extra range over the other camcorders gives the HC7 the ability to stretch the camcorder's image gathering ability in both very low light and very bright light. The Cam Control dial is good for making shutter speed adjustments, but you'll face the same delays in toggling from one parameter to another as you make multiple adjustments to your image. The HC7 includes a two auto shutter options as well. Auto Slow Shutter can be turned on or off, and when it's engaged, it places the floor of auto shutter speed at 1/30 allowing for some additional light gathering without a major cadence change. Color Slow Shutter drops out the floor entirely.
Panasonic HDC-SD1 - The shutter speed settings available on the HDC-SD1 are 1/60, 1/100, 1/120, 1/180, 1/250, 1/350, 1/500, 1/750, 1/1000, 1/1500, 1/2000, 1/3000, 1/4000, and 1/8000 - there are no manual settings below 1/60. To drop your shutter speed below 1/60, your only choice is MagicPix mode, which works like Sony's Color Slow Shutter, and drops the floor from the auto shutter speed control. This is useful to be sure, but in the absence of manual sub-1/60 shutter speed control, we'd prefer to see at least a quality control option like Auto Slow Shutter that set the floor at 1/30. It also continues to surprise us that Panasonic, king of the manual control hill, does not offer slower shutter speeds.
JVC GZ-HD7 - The big difference that JVC brings to the table is the image control cluster on the back of the HD7 body, including shutter speed. Like Aperture and brightness, shutter speed is engaged by pressing the S button. The set dial below is used to cycle through settings which include 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/80, 1/100, 1/250, 1/500, 1/1000, 1/2000, and 1/4000. We like the dedicated buttons for shutter speed and aperture, and the set dial, because they allow for instant access and very fast adjustment to these parameters. The arrangement makes toggling between these two adjustments faster than on the other three HD cams - though we wish JVC hadn't stopped there. White balance in particular would have benefited from a dedicated button.

Gain
Canon HV20 - The Canon HV20 offers no independent manual control over gain.
Sony HDR-HC7 - The Sony HDR-HC7 offers no independent manual control over gain.
Panasonic HDC-SD1 - There's actually something to comment on here, unlike the three camcorders above. As mentioned in the Exposure section, the Panasonic HDC-SD1 places iris and gain on a continuous scale so that there's no boundary between the two. Purists might scoff at this treatment - but we have to say it makes intuitive sense. Both controls govern brightness, and keeping the two linked makes it impossible to make the mistake of shooting with gain levels at +6dB when you don't mean to. Panasonic has included gain control on its consumer camcorders for years, and deserves kudos for giving users the option.
Gain setting for the HDC-SD1 include 0dB, 3dB, 6dB, 9dB, 12dB, 15 dB, and 18dB, with an incremental step between each whole step, for a total of 12 settings.
JVC GZ-HD7 - JVC GZ-HD7 offers no manual gain adjustment over gain, but you can disable automatic gain, an option that is common on JVCs. To enable or disable auto gain, you'll need to navigate to the Gain Up option in the Video sub-menu of the Administrative menu.
