    I'm kinda seconding the general thought everyone else is voicing. Disappointment over the lack of improvement. But I think with some more work, it could be made to do better.

    Let's face the facts though - it's taped onto the phone.

    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".

    The lens may be borrowed from a DSLR but what it makes is an EVIL camera. EVIL = Electronic Viewfinder, Interchangable Lens.

    You don't need to be skeptical. This will produce crappy results. You're still pushing the light through a tiny dirty lens and a tiny aperture. The iphone's autofocus will be fighting your attempts to get the focus you want (unless there's a way to turn off autofocus). The iphone 4 may be a nifty point and shoot camera, but it's not SLR quality regardless of the number of pixels.

    I'd title this one "I don't know anything about optics or photography, but I can machine a bracket out of aluminum."

    Actually many recent DSLRs use a penta-mirror system because it's cheaper. But your point is valid.

    Moron, SLR requires that it has a few mirrors and some moving parts.

    Please see: http://en.wikipedia.org/wiki/Digital_single-lens_reflex_camera [wikipedia.org]

    And read it, not just look at the pictures. Nothing external to the camera that you can see has anything to do with SLR, its all internal mechanics and not the fact that you can screw on a different lens.

    So this guy takes an iPhone and an OWLE [wantowle.com] and, what?

    He mentions adapters for lenses, but that's not even needed for the Canon lens he's using.

    The only thing he's actually created is an utterly incorrect definition of DSLR.

    I don't know about the iPhone 4, but the T-Mobile G1 has a mechanical (probably magnetic, the way optical drives focus) autofocus. You can hear it when you go to take a photo.

    It is somewhat disappointing, to say the least. I do give some credit for posting it though. Even though things didn't work out as planned it is nice to see what happened.

    No kidding - I was looking forward to learning how he removed the iPhone's crappy lens and then got an slr lens exactly the right distance from the film plane to be useful. This was followed by a realization that he'd be wasting about 95% of the glass, since the sensor's size is a tiny fraction of a crop or 35mm sensor.

    If he does stick with the iPhone lens, he's sticking the wrong optics in front. Canon and many other manufacturers make telephoto and wide angle lenses designed to fit over existing optics. This would get rid of the blue fringing, blurriness etc... in his sample pics. He could have saved a lot of time and effort by getting a Canon TC-DC58N [amazon.com] lens on eBay and modded a LADC58B [amazon.com] lens mount (or similar) to get the spacing right.

    The stunning camera in the N900 also has a real focus. Sometimes it actually makes a thunk noise.
    Also you can alter the focus settings with two taps.

    It seems to improve autofocus

    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].

    The crop factor is probably somewhere in the neighborhood of 12-15, I'd guess. I'm pretty sure that the Canon 70-300/5.6 isn't sharp enough to outresolve the tiny little pixels on the sensor, so you'd be left with a greatly magnified but fuzzy mess.

    This guy would have had to remove the iPhone's own lens, otherwise he couldn't focus at all -- the lens is projecting an image behind it, and there's no way the iPhone can then focus on it.

    I've never heard of the Canon 35-80; I imagine that's just an old and cheap lens he had lying around.

    Minor correction: the 4/3 format is *not* the EVF-driven mirrorless system. Four Thirds is a perfectly ordinary SLR system that works in the standard way (and is the one I use, incidentally.) You're thinking of "micro Four Thirds", which uses the same sensors as regular 4/3 (crop factor 2), but has no mirror and uses an EVF. Ordinary 4/3 lenses can mount to micro 4/3 cameras with an adapter (which is just a spacer to fix up the mount-sensor distance)

    Quoting The Not So Fine Blog...

    I created this blog to document the steps I'm taking in making an iPhone DSLR.
    The honest truth is, I really dont know anything about DSLRs aside from the fact that you press the button and it snaps the picture.
    So whether the feat is actually possible or not, I'm in to to find out.

    Also:

    Now by no means would I consider myself a professional photographer.
    Heck... I am by would I even consider myself an amateur photographer.
    The truth is I really know nothing about photography.
    Before starting this endeavor the most I knew about cameras was that you push the button and it takes a picture.

    DSLR Lens Mount
    Posted on June 28, 2010 by Jeremy Salvador

    Canon Extension Tube
            Canon Extension Tube

    I have Canon EF lenses and have been looking for a mount so the iPhone DSLR can easily interchange the lenses. So far all the products I've looked at are fairly expensive (in the $100-$200) range.
      Then I stumbled upon the Canon Extension Tube. ($8.78) from SunTek.

    This tube ring mount is generally used for macro shots and can fit all Canon EOS DSLR / SLR Camera EF lenses.

    The Package Includes:

    Canon Lens Mount Adapter Ring
            Canon Lens Mount Adapter Ring

      (1) Camera body mount adapter
      (1) 9mm tube (Tube 1)
      (1) 16mm tube (Tube 2)
      (1) 30mm tube (Tube 3)
      and most importantly! (1) Lens mount adapter

    The Canon EF Lens Mount Adapter will allow lenses to be easily interchanged from the iPhone DSLR.
    Now to figure out how to attach this thing to the iPhone.

    And here is how - you buy an Owle:

    Owle Bubo
    Posted on July 6, 2010 by Jeremy Salvador
    The Owle Bubo is one of the most impressive iPhone accessories I've ever seen and I think it's going to be perfect as a housing for my iPhone DSLR. It's a camera mount that brings the best features of a camcorder to the iPhone 3GS: stability, optics, microphones and tripods!

    The Owle Bubo is made of a solid piece of anodized billet aluminum making it extremely durable and virtually indestructible. This full aluminum frame gives the housing a good 1.1 lbs in weight giving the housing just enough weight to make keep the device steady. The two handle grips make it a real breeze to carry. Also the Owle provides 4 x 1/4-20 female threaded mounting holes so you can actually screw this thing into a standard tripod.

    The Owle Bubo comes standard with 37mm lens threading, as well as a 0.45x wide angle/ macro lens combination. This is a real piece of optics, delivering stunning images with better color saturation, contrast and sharpness than is possible with the iPhone's camera alone. The wide angle lens accepts 49mm screw in filters. So with a 49mm-58mm step up ring, I'll be able to attach the Canon Lens Mount Adapter Ring to this housing.

    Hopefully, Jeremy is something like 9 or 10.
    Cause, a "grown person" doing something like this and calling it a "prototype" is like "creating" a portable laser printer by getting a really long power cord and some straps on ebay.
