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.

Well with a EF 70-300mm f/4-5.6 IS USM imagine what the equivalent focal length is if you take crop factor into account. What would the crop factor be anyhow - 32.0?
Anyway this is not an SLR. SLR = Single Lens Reflex. Last I checked, there is no optical viewfinder, no pentaprism or pentamirror, nothing that would make it an SLR. In fact for a camera to be an SLR, technically speaking, interchangable lenses are not even required. What is required is a single lens provides the image for both the sensor/film and the optical viewfinder. This is more similar to the increasingly popular 4/3 format where the sensor provides the image for an EVF, but the lenses are interchangeable.
It is a neat project but it seems like it would be a royal pain in the ass to use. Your EF lens will be stuck at full-open aperture (so you will have no DOF) and while you are trying to use the manual focus on the lens, your iPhone will be trying to use its internal focus, making it very, very difficult to focus. It will also be incredibly difficult to hold steady enough to capture sharp images; the crop factor will be like using a really, really long lens and because the lens isn't powered by the iPhone you will not be able to use the lens's IS/VR/OS feature so there is no way to counteract camera shake. To make matters worse there is zero control over the iPhone's "shutter speed" so there is no way to even use the 1/(equivalent focal length) rule of thumb, so you would be restricted to using a very steady tripod.
Also, EF-S lenses would have been a better (and generally less expensive) choice as they mount closer to the sensor.
Sample images? I didn't see any.

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.

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)

The Canon EF Lens Mount Adapter will allow lenses to be easily interchanged from the iPhone DSLR.

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.

The sensor sizes on modern DSLR's are no smaller than half the diagonal of 35mm film, and that sensor size (the Four Thirds format) is perfectly adequate to make great images. All the other sensors are bigger.

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.

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...

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.

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.

No "funnel" or "fancy optics" are necessary, assuming that the lens mount is fitted in such a way that it focuses correctly to the image plane through the iPhone's lens. You can use a regular SLR lens with a smaller sensor, but it's going to be an extremely long focal leng

"become equivalent to" is what I meant to say.

Wrong, wrong, wrong, and very wrong.
That is what is called an 'Lens'

And he has attached the 'Lens' to a 'camera phone'
http://en.wikipedia.org/wiki/Camera_phone [wikipedia.org]
an SLR is a camera that has various mechanical moving parts, that allow you to split the same light that will be hitting the film or sensor, so that you can see this with your own eye, and then the millisecond you hit the shutter button, the Reflex mirror, jumps out of the way, and the shot is taken with almost the exact same light you where seeing that was sent to your eyes.

This is just a phone that might as well be taped to a large magnifying glass, there are no SLR parts in the lens of a SLR camera.

At this point is seems to be an argument over semantics and SLR definition.
Even though I got moded underrated, I win; as I have have photographs taken with and SLR published in national publications and work as a professional photographer.

"Dual lens reflex" means something different -- some old cameras have two identical lenses mounted near each other. You look through one and shoot through the other, with no movable flippy-mirror.

It honestly gets even more complex than that.
I've had issues even acquiring images under a 100x magnification lens with 200x the amount of photon flux. I'm talking about having replaced the crap incandescent filament bulb with LED and we still have problems even with the diodes being configured to output maximum luminous flux.
It's just a problem involving optical physics. Maybe when we get the lenses lined with a silver compound, we can get better resolution images.

Well, there is already a lens in front of the iPhone's sensor, so I don't think crop factor due to sensor size comes into play.
The iPhone 4 is supposed to have a 28mm equivalent Field of View. I'm not sure what kind of vignetting this would give on most lenses, but let's assume we put a full-frame lens on it and there is no vignetting, my guess would be that the effective 'crop-factor' would be something around 1.25 (35/28).
Please note I'm really not sure about this, so feel free to correct me.
