They're cheaper, modular, and easier to maintain. If they were standard, profit margins would take a hit.

Handling task loading has muc more to do with dive skill than knowing how to operate an SLR. Besides, I think my point and shoot has far more functions than either of my DSLRs. It certainly has more than my film SLRs.

Agreed, I was perplexed by that comment. My first camera was an SLR (albeit not digital). Also agree regarding the histogram. It's perhaps the single greatest learning tool available in digital cameras. ... Once you learn how to read it. Too bad so many google results will turn up Expose To...

I've always wondered if the worries about stopped-down diffraction effects are overblown. Ansel Adams, Edward Weston, Imogen Cunningham, etc all shot narrow apertures (in fact they and some others formed a club called Group f.64), and I've never seen criticism about aperture diffraction...

f/3 (odd number, I'll call it 2.8) to f/10 is a *huge* range. That's like saying "I'm going to Vegas, should I bring something between 1000 and 60000 dollars?" Photography is equal parts technique and creativity. Selecting aperture and shutter speeds have both creative and technical...

I also use Smugmug. It's expensive, but for me it's worth the cost for the service and ability to personalize. I don't sell (use a Power level account). With Pro, you can set your own prices and access a better print lab (bay photo). And when you think about it, it's not really THAT...

I'm willing to bet most rebel owners never move beyond the kit lens either - I rarely see anything else. It just seems weird to me to offer a camera with interchangeable lenses, but not offer any dramatic weight savings versus the EF-S series. IMO a micro 4/3 or G1x sized sensor would have...

If the controls are indeed usable in a housing, this could be a cool underwater cam. Topside it makes zero sense to me. Once you add glass, it's not a pocket cam. If you're wearing a strap, why not bring a SLR? Only weight savings is in the body for equivalent crop glass (lighter than full...

Credentials don't necessarily equate to credibility. For example, the author of this article is a scientist, an Instructor Trainer, an officer with CMAS, and yet he believes (and perhaps teaches) that air creates gravity, and that astronauts "float" because they've left the atmosphere and are...

Funny, I adore topside photography but have little interest in shooing underwater. I prefer to take video.

Good subject, good light, good exposure, good composition. If you have those things, you'll have a good picture whether you're shooting a phase one iq180, a nikon d7000, a canon 7d, a point and shoot or a Polaroid. For the most part, when comparing modern digital cameras, the IQ differences...

Awesome. I wish I'd had a better camera when I was there. Any top side photos?

The biggest mistake I personally make with AF is underestimating the size of the sensors. It's easy to think of the representative dot in the viewfinder as the sensor. In reality, the sensors are quite a bit bigger. They aren't dots; they're lines much longer than the diameter of the dot. Cross...

Great photo Scott. Yah. The camera is just a tool and isn't the most important one. But I have to assume that the extra two stops of shadow detail the D7000 has over the 7D may have come in handy for that capture :P

I think control layout and menu navigation has a lot more to do with what you're used to than overall shape and size (i.e. feel). After a short disappointing stint with Olympus (in their CCD days) I used to shoot a "rebel" series canon (350D). My main impetus to upgrade it was feel. It's...

Maybe on some models canon beats out Nikon's video, but not with the 7D vs d7000. And the d7000 obliterates the 7d for stills (especially due to the DR afforded by the Sony sensor tech). That said, I think canon has the more compelling lens lineup (the TSE is maybe the best landscape lens...

Not necessarily. http://photsy.com/blog/?p=457

I don't think I had *anything* mastered after OW. That's the problem.

That is buoyancy control. Limiting the term to "the ability to maintain depth" is kinda... strange. Buoyancy control is the ability to use buoyancy to a desired end. Maintaining a desired depth may be one goal, but getting to it in a specific way (eg not too fast and not to slow) is another
