Moving to Pentax

If I was looking at moving over to the Pentax system which would be the best camera to go for currently? (K-5, K-7 K20-D).

I currently have a Canon 5D classic and I have quite a lot of older M42 lenses and Pentax gear coming my way and it would either make my canon equipment redundant or end up not getting used. Which camera would compare to the quality I get from my 5D.

I believe the M42 lenses would work better with a pentax rather than using an adapter on my 5D as there are mirror clearance issues with the FF Canon. I am also finding I am tending to just use my 50mm f/1.8 prime on the 5D rather than the other zooms I have essentially making them a bit redundant.

I would also gain image stabilisation and pop up flash from moving over.

I did learn photography on an Ashai Pentax SV from the 1960's with a 55mm Super Takumar lens which I still have.

If i did get a Pentax DSLR I would sell my canon stuff on.

All advice would be greatly appreciated.

K5 is your best bet. You will still need a M42 to K mount adapter.
Keep in mind the K5 is a APS-C sized sensor and not as big as your 5D's sensor, but as long as you are comfortable with that then go for it!

Everyone seems to like the K5 based on reviews.

The K-5 is going to be your best (and Pentax's) for upgrading optics comparable to an older FF camera, and for use of all the great older M42 glass out there. I have quite a few M42 based lenses that I use on my K-5 and absolutely love it. Just make sure the M42 to PK adapters you pickup are the infinity focus ones, and not the flat flanged ones. The Official Pentax one is nice and all but pricey, I've picked up a few cheapy knock off ones from here and have had little issue with them.

The K5 is the latest and greatest. Some magazine named it CAMERA OF THE DECADE. Whew. A newer hotter replacement may or may not be announced soon, which may or may not drive down K5 prices. So the questions: Can you wait? Can you hope? How much do you want to spend?

Don't have a K5 but from all the reviews and stuff I have to agree. Though I'm curious to see what comes next since Ricoh is in the picture pun intended =D

I'm currently 99% satisfied with my k-7… but the 1% loss is due to the noise at even 800 iso—which seems to be largely improved on the k-5. though i'm holding off on buying a better camera until a new pentax comes out, and recommend you do so as well. since the k-5 isn't terribly different from the k-7, I expect the following release to be a slightly larger improvement.

if you want my lens recommendation, the 55mm 1.4 da* is my favorite.

Another vote for the K-5. It's everything you'd need in an APS-C camera moving from a 5-D classic. Enjoy the difference.

Pentax have no full frame dslr.

If you want a true equivalent for mounting M42 stuff without mirror clearance issue, you should get Sony A850.

If crop factor is not an issue for you, then K-5 is the only one that can match Canon 5D quality
