What a waste of time and money. The sensor itself is still a piece of junk, no matter what quality lens you put on it..

Wow, at first I thought this was a joke. After all, if you have a decent lens then you are not messing with a cellphone to take pics. If you are lugging around lenses and tripods, having a real DSLR with you is not a problem, it\'s often the lightest component in the setup.
But it seems this is real, which would make it one of the most stupid ideas ever devised, congratulations to the designer for taking that prize...

..some things are just plain stupid!

\"the iPhone SLR Mount certainly looks to be a step in the right direction\"... you ARE joking, right!?
$250 to attach a lens bigger, heavier and less portable to my iPhone, to produce a camera lower in quality, and more difficult to handle than the SLR I would have to own in order to have the lenses. Genius. This idea is pure garbage.

Its criminal to put an L-series lens on an iphone. That last pic makes me cringe..

Purified garbage. You don\'t take pics with a phone, no matter what brand it is, its camera is still shit.

With the reportedly improved 8mega pix camera on the upcoming iphone 5, this may not be a bad idea. Probably not with the monster zoom lens shown in the last picture but with the 50mm prime lens in the second last pic it should be compact/ light enough as a replacement to your point and shoot/ video cam on holidays.

Technology, what will they come up with next?

Just because you can, doesn\'t mean you should. After you attach your iPhone to your EF-300 lens, then duct tape it to your action sports helmet and take some rad shots of yourself running through traffic on the expressway. Now that rules.

\"Adapter lets you mount SLR lenses on iPhone\"
Looks more like mounting an iPhone onto the lens.
It is STILL a waste of a good lens.
