Yes you won't need much lenses that way but then still it will cost resources that are i think better spend elsewhere.
One thing they might do is stop producing K-mount lenses.
The K-mount is designed for 135/FF, they could make the camera smaller by using a mount designed for APS-C, this will off course kill all dreams for a Pentax FF camera but with a slightly larger mount and a shorter register distance they can make cameras smaller and produce faster lenses for it.
Standard zoom lenses with f/2 for example, or standard primes f/1 and probably faster can be made won't be dreams any more.
They might even be able to offer some counter weight against the Nikon and Canon 135/FF cameras that way, the APS-C sensor is mature enough to be seen as professional solution now if they can offer the same quality lenses and the some kind of DOFs but with a much smaller system they might have something.
They can make the cheaper camera simply mirror less to press the cost and they might be slightly bigger then what other offers but you've a complete system to grow in.
Hopefully Ricoh is daring enough.
As long as they provide a good K-mount adapter, i doubt many would mind the switch.
Originally posted by gazonk But she's still contemplating the NEX-7 and other advanced mirrorless cameras. Why? Because she wants a camera that's lightweight and small enough to be with her almost all the time. The K-5, or even the K-r, is just too heavy and big. A similar (to the NEX-7) mirrorless Pentax with a good adapter supporting screw drive AF would be her dream camera (because she could then borrow from my and my daughter's K-mount lenses).
The camera is indeed small but the lenses are just as big, therefore the little you gain with the smaller size and weight is only relative very small when you've 2 or 3 lenses.
Besides that, with the larger lenses like f/2.8 zooms for example i like to have a slightly bigger body that's also heavier because the balance and handling would then be so much better. I believe i'm not the only one who thinks this way.
Therefore if you want to get more serious the DSLR's we have now are still the best choice.
The Nex 7 looks good on paper but just go to the store and make a little setup.
I wanted to say get a Pentax K5 + DA*16-50 + DA*50-135 and compare with... but besides the CZ Sonnar 24 mm f/1.8 NEX doesn't have any higher end lenses.
So you end up comparing the K5 + 18-55 + 50-200 with the NEX7 + 18-55 + 55-210, i'm pretty sure it doesn't make any difference in size.
The only real small lens Sony has is the 16mm, for the rest the other primes aren't that larger but they won't be much smaller then a K5 or Kr with a limited lens.
I never understood Sony reasons with the NEX, it just doesn't make much sense when you look at the whole system they have now.
If you want something small Olympus or Panasonic has better system, not sure about Nikon, their lenses don't look that small... the Q also got the message right although they are taking a gamble with the really small sensor, hopefully it works out.
