I purchased a K10D about 18 months ago, and was completely awed by the camera, it was a huge improvement over my ist*. When the K20D was announced, I was mostly interested in the additional resolution, since I print many of my photos to 12 by 18 inches. The surprise was all the other improvements made to the camera, like lower noise, higher speed, faster focus, slightly larger screen, live preview, burst mode (21 frames per sec), the ability to shoot B&W, and more... On a recent kayak trip, a harbor seal popped up near the kayak. The attached image was taken with the K20D and the new Pentax 50-135mm lens with the kayak bobbing in the water. The resulting image says a lot. The focus and resolution are so good, you can see the spiral twist in the whiskers. I rated this camera as a 5, but the definition of 5 is "perfect" and nothing is this camera is definitely a 4.8 or 4.9

Specifications didn't cover it all

Bought this camera with the intention of shooting some of my work with strobes. I was very disappointed after reading in the instruction manual that "any use of high-voltage or high-current flashes may cause a camera breakdown." What a bummer. This clearly should have been stated under the camera specifications. Had it been, I certainly would not have bought it. Are all digital cameras with X-sync sockets like this?

Great camera!


from New England  -  Semi-pro Photographer

I'd love to have the K-7, with its smaller body and faster shutter mechanism, but the K20D is nearly as good and a lot cheaper right now. I think it will be good enough for me for a while, and then I can upgrade to the K-7 or its successor at a later date.


Don't stick only with the big names.


from NYC  -  Photo Enthusiast

Amazing camera, lots of specials settings, user customization, and amazing IQ, in a very durable body. As a long time canon user i was a little afraid to move to Pentax but never regraded for giving it a chance. Got it for an amazing price, and it really feels like a pro camera in your hands compare to the same price category from canon, Nikon, and Sony. Very happy customer.


Bought two


from Hilo, Hi.  -  Photo Enthusiast

Like the strong build, weatherproof which i need as i hike into water fall and river areas and we get plenty of rain in Hilo.


Best For Price!


from Woburn, Ma.  -  Photo Enthusiast

Good solid feel. Pentax has got me back into fun photography. Loaded with useful features. A few changes in your settings gives you a full range with your older Pentax lenses. Try that with brands X and Y! I love the noise reduction settings for high ISO's. Great camera at a reasonable price!

The K20D is awesome


from Massachusetts  -  Photo Enthusiast

I've had the K20D since about June 2008 and I love it and haven't had any problems with it, other than the battery which died within a few months. However, the Power2000 NP-400/D-L150 batteries are under $20 and work great with the Pentax charger (vs $45+ for the Pentax batteries). I also recommend the Pentax SMCP-DA 18mm - 250mm lens as a good all around lens. And since I like doing scenic/wildlife photography, I also eventually bought a Sigma 50-500mm EX/HSM lens which works well with the K20D, though some might not like the weight of it, I can overlook it given the capabilities of it. This combination is great for getting up-close to wildlife.I'm not sure why anyone would choose other major brand digital SLRs which are around the same price but with less resolution. It just doesn't make sense to me.The only complaint, besides the battery, is that the interval shooting is limited to 99 images. That means that without an external trigger/intervalometer, you can only automate shooting a max of 99 frames w/o intervention if your doing time-lapse photography, although I did track down a company that makes compatible intervalometer for around $50 which I'm waiting to receive. The ~$140 Canon TC-80N3 might work with the K20D (if anyone has tried this, I would be curious to know if it works).


Love my Pentax K20D


from Washington, DC  -  Photo Enthusiast

I have used my K20D for 3 months now. I love the camera. The controls are logical and easy to use once you know them. I particularly like the in-camera image stabilization. I have taken some lower light shots, hand held that are very crisp that, when I tried the shots without stabilization were blurred. Just a great, solid feeling camera.

Pentax K20D


from Rapid City, SD  -  Semi-pro Photographer

I love this camera!


Excellent Camera


from Austin, Texas, USA  -  Semi-pro Photographer

This camera is very well built, sealed and comfortable to hold in the hand. The 15 megapixels are more than adequate and the price is simply unbelievable. For the same features in other brands you can't buy as much camera.


Best Camera I've ever owned


from Mobile, AL  -  Photo Enthusiast

I shoot landscapes, objects, wildlife and some portraiture, the K20D is everything it says and more. I have had no problems with this camera and I find it very easy to learn and use. I could not be happier with this purchase.

Not as good with old lenses as wanted


from Ann Arbor, MI  -  Photo Enthusiast

I was encouraged to buy the camera because it would be compatible with my existing lenses. But that compatibility is severely limited and I had to purchase a new lens in order to be able to use the camera adequately. So I had to spend more money that I wanted to, but it works great with the new lens. I was disappointed in its ability for manual focus. The mirror in my existing camera is so much easier to use.
