Compare it to what you see when you look (with your eye, which is a lens) through the rear of a lens. You see a round patch of light, not a whole view of the world. The iPhone would see the same thing. Also, if you _did_ remove the original lens, you'd end up with an enormous crop factor, turning every SLR lens into a very long tele. Try holding that steady

        I've done a similar thing with the large front lens from a set of binoculars on my camera as a $15 macro lens.

        Works decent enough, but since I picked cheap binocs, the lens was attached to the front tube instead of being separate, so the edge shows a bit if I'm zoomed all the way out. I could saw it down but the eyepiece cap fits perfectly over the open end.

          Yes. Those are photos of a defocused patch of light. My original statement still stands. The only way this would work is by taking pictures through an SLR viewfinder, which has, you know, a ground glass on which the projected image forms. You cannot otherwise stack two photographic lenses.

    DSLR does not mean "detachable lens". It means "Digital Single Lens Reflex", or "digital camera that uses a mechanical mirror system and pentaprism to direct light from the lens to an optical viewfinder on the back of the camera".

    http://en.wikipedia.org/wiki/Dslr [wikipedia.org]

    In fact, it has nothing to do with detachable lenses. That is a completely different technology, which just happens to be commonly (but not universally) paired with (D)SLR hardware. Nor is the mechanical mirror or pentaprism contained in the lens. The SLR mechanism(s) are in the camera body, which clearly do not exist in the iPhone nor the mount that the phone and lens(es) are attached to.

    What this device provides is simply detachable lenses for the iPhone camera system. Detachable lens camera systems have been available for non-SLR cameras for quite some time.

    This horribly wrong use of technical terms really should not be showing up on the site that proclaims itself as "news for nerds, stuff that matters".

      Absolutely right. I just purchased a Sony NEX-5 which to me is the tipping point of SLR digital camera technology. Sure, a pure DSLR will always have some advantages, but I think these are now superseded by all of the benefits gotten by the new mirror-less APS-C and Micro Four Thirds cameras.

        Snark: the NEX-5 isn't a DSLR either, since it doesn't have a reflex mirror. Doesn't make it suck, though -- not everything has to be a SLR to be a good camera.

        Question about it -- I saw pictures of the thing and it looks so darn hard to use. No viewfinder, no real way to hold it, and badly unbalanced if you put any sort of ambitious lens on it. Obviously it takes good images, but how's the actual experience of shooting with it?

        • by S-100 (1295224)
          Snark? Hardly. Read again. My opinion is that cameras like the NEX-5 have the potential to replace DSLRs for the majority of people looking for cameras like that. I never said it WAS an SLR (which it obviously isn't.)

          I don't have the camera in hand yet, so I can't comment on handling. As for a viewfinder, there will be one that bolts onto the new proprietary hot shoe on top. That's currently how you attach the flash or an external stereo mic (which bypasses the built-in mics). I've very rarely used t

            I mostly do outdoor wildlife photography, so I like viewfinders -- I can't see the screen in the sunlight. Good that there's at least the option for one on the NEX if you want one.

            For small pancake lenses, I agree -- this, or equivalently the Olympus Micro 4/3 cameras, are a good direction for design to go in. But I'd be interested to see how it handles with a 1.5 or 2-pound on the front, though; if your hand on the lens has to bear most of the weight all the time, it seems

              Well, I'm used to "unbalanced" on SLRs as well, when I attach my 800mm mirror lens to my old film SLR. To solve the problem, a tripod mount is attached to the lens, not the camera. Same thing works here with mirror-less digital cameras, except they will be more common. I believe the coming 18-200mm E-mount lens from Sony already includes its own tripod mount.

              And what puts it over the top for me is that the new E mount lenses also work on Sony's new line of pro-sumer camcorders, which are similarly compa

        Well, maybe improve accuracy in some cases, but the contrast detection AF of non-DSLRs is usually slower than phase detection AF of DSLRs. The very best CDAF is comparable with PDAF of average DSLRs, and then there are the sports cameras...

        Have you tried a modern digital viewfinder? For example the VF of the Olympus EP2. I'd say it has enough resolution to not make a significant difference. It has 100% coverage (of course :-) and 1.15x mag. And for those still life photos you can magnify a portion of the view (up to 10x?) to fine-tune the focus. And best of all, the flange focal distance is small enough to use Leica M-lenses at infinity -- but the 2x "crop factor" may be a curse or a blessing...

        Many large manufacturers of DSLR's, such as Canon and Sony, have started removing the mirrors from their prosumer-level camera's in exchange for sensors that can work in different modes.

        Well, Canon (and Nikon) are still on the fence. Nikon may (or may not) present a mirrorless system camera at Photokina, Sony has their new NEX-system, then there's Olympus and Panasonic (micro four thirds), and yet another system, Samsung NX. Even Ricoh is jumping on the bandwagon, in their own idiosyncratic way [dpreview.com].

          I have to say the CDAF on my Panasonic G1 when using the kit lens feels as fast as the 70-200 f/4L AF on my 40D. This is definitely "fast AF" territory. This is not the case with the other lenses i've tried on the lineup, but it definitely goes to show that it is possible.

          And the best thing about CDAF is that it actually gets the damn focus right where it needs to be. Unlike everything else out there. The fact that latest DSLRs have "AF fine tune" settings to deal with the mess that is PDAF attests to this.
