Apple MacBook Pro 2009-.

The Canopy Kapok (shown here in white,Samsung Series 9 NP900X3A, but currently available only in black) adds a tripod-mount case and shutter-release buttons to your iPhone 4.

The case sports two shutter-control buttons, the functions of which aren't immediately clear. Nor are they explained anywhere--not in the app, not in the included instruction manual,Dell Latitude E6520, and not on Canopy's Web site (which does have some instructional videos,Sony HDR-TD10, just none of them focusing on the buttons).
Also,Thinkpad w510, the moment you plug your iPhone into the case,Sony HVR-Z7E, you're directed to the App Store page to download the free Canopy Camera Tools app--a nice little time-saver. More on that app in a moment.
You can use the case with the included base, which sports a mini-ball tripod, or any standard tripod. I like the base, though it's not terribly versatile: it's designed solely to sit on a flat surface and affords a limited range of movement.
Fortunately,ASUS G73, Camera Tools is quite capable,Sony HVR-Z7U, offering such advanced features as separate focus and exposure points,Sony HDR-CX500V, time-delay shooting, and interval recording. What's missing is any kind of HDR option,Canon XH A1, which I've found can really help in light-challenged settings. (Tip: You can use the app even if you don't buy the Kapok.)
The case is your typical matte-black two-piece,hp 2540P, with about 5/8 of an inch extra at the bottom to accommodate the dock connector. Other than that,Apple MacBook Pro 2009, it's very slim and light--good all-around protection if you decide to leave your iPhone in it full time.
At $69.95,Panasonic AG-HVX200A, the Canopy Kapok isn't cheap,Sony PMW-EX3, but it seems reasonable for what you get. Indeed,JVC GY HM100U, if you really want to maximize your iPhone's value as a camera and/or camcorder, this gives you the key ingredient: tripod support. (That said, there are much more affordable options available,Apple MacBook Air Summer 2009, like the $20 Glif and $39.95 Joby Gorillapod. And once iOS 5 arrives, you'll get a "free" shutter-release button to boot.)
The Canopy Kapok is an iPhone 4 case with a built-in tripod mount. It also comes with a pair of shutter-control buttons and a stand. It's not a perfect product, and the impending release of iOS 5 (which will turn the iPhone's volume-down button into a shutter release) limits its overall value. But you may find it worthwhile,HP EliteBook 8540W XT904UT, if only for mounting your iPhone on your favorite tripod.
The Kapok comes in a clear-plastic shell that's maddeningly difficult to open--until you realize that the thick black bottom of the shell is actually the included stand. Also, there's a finger-hole near the top where you can reach in to push the Kapok down and out.

When used with the Canopy Camera Tools app,Panasonic AG HMC70, the left button locks the exposure and white-balance settings (or snaps a still photo during video recording), while the right one focuses and fires the shutter. These latter actions require a half-press and full-press, just like on many real cameras.
Canopy has released Kapok APIs to developers so that other camera apps can be made to work with it. For the moment, however,HP EliteBook 8540p XT923UT, it's Camera Tools or nothing; the case doesn't work with Apple's stock Camera app.
With its 5-megapixel camera and 720p video recorder,HP Envy 17 3D, the
iPhone 4 can capture some pretty impressive-looking images--as long as you hold it perfectly still. Indeed,Panasonic HDC-HS900, as any savvy photographer or videographer knows,Panasonic AG HVX205A, if you want the best results,Sony HDR-AX2000, you need a tripod.
