K Mount Speed Booster?

Looks like Fotodiox might soon raise a few smiles around here (if I've read this right, that is):

That's got to be a typo. . .unless they adapt medium format glass to the K-mount. They probably mean the Q.

Not full-frame lenses adapted to the APS-C sensor? Or these things shorten the register distance, eh?

Yep, they do. I've got a K-mount/Nex Lens Turbo, and it's several millimeters thinner than a basic adapter tube.

The Fotodiox Pentax adapter is for mounting full-frame K lenses on a m4/3 camera, m4/3 -> APS-C. Anyone with a Pentax DSLR is already there.

I have an RJ Turbo which mounts my K lenses to my a6000, so APS-C -> FF. That's a better trick.

...and there was me wishfully thinking someone had finally found a use for all that empty space in my K-01's not-mirror box.

In principle you could make an adapter that sit inside the empty (mirror-free) space in the K-01, that does what the speed boosters does. But this ain't that.

Actually you couldn't since a focal reducer also reduces the register (flange distance) of the lens.

What if Pentax/Ricoh makes a body similar to K01 but with a shorter register distance and a built-in speed booster thingy? This way they don't have to increase sensor size but can market it as pseudo-full frame.

I wonder how the cost of something like this would compare to just sticking a FF sensor in there in the first place.

This would be great! It looks like there might be enough room to fit an adapter completely inside the K-01, at the proper register distance. But nobody will probably ever make anything for that cam ever again~

While the lower-quality Chinese knock-offs are fairly cheap, the decent metabones boosters, which themselves result in at least some image degradation, are a few hundred bucks each. Probably the total package would not come in much cheaper than the larger sensor, and the quality tradeoff would not be worth it.

True. Oh well, just another day imagining a Pentax FF...

The DOF of a 67 field camera on a Pentax Q - that would be...interesting.
