I got the book and Yvonne knows his stuff. Another nice thing is that he tells you how great the camera is in addition to giving excellent examples.

I have seen so many reviews of Pentax cameras with the "Pro-sumer" or "advanced amateur" moniker when it (K10D, K20D, K7) really deserves a pro-moniker due to the features. When I bought my K20D, I researched for months. NO OTHER CAMERA had the flexibility, backward lens compatibility, in camera stabilization (cheaper lenses, Yeah!) for the price. My other options for what the K20D had to offer sensor and pixel-wise were minimum $2500 dollar Canons and Nikons and Sony's.

Here's the deal. I'm thinking that Canon and Nikon tell the reviewer to keep the gear after the review. To tell you the truth, I would favor a free-for-me-to-keep camera as opposed to a loaner "for review only." Who am I going to keep happy? The loaner guy or the guy who lets me keep an awesome piece of photographic equipment?

I prefer Pentax. The K20D has many more features than any comparably priced camera on the market at this time.

Look at Toyota, Datsun and Honda in the '70's. They were given all kinds of crap, but were cars of quality. It just took time for the consumer to realize this. Pentax was at the top in the '60's and with the K-7 and Hoya backing Pentax will be at the top again.

I have the OEM Pentax Battery and also 5 off brand that I rotate through the K20D body and grip. I have the grip set as the primary. #1 in the body, #2 in grip, when #2 in grip runs low, I put #1 from body in grip and #2 on the charger, #3 goes in camera and so on . It's a good rotation to keep all batteries at their peak.

I use my K20D every day at work for about 15-25 shot w/flash and w/o for industrial photos. The camera is used extensively on weekends for wildlife/nature and landscape shots (since January when I bought the K20D, I have over 12000 shots) I rotate the batteries when I see the "half-full" indication on the upper LCD.

Hi, I'm Bill. I've have been involved in photography for about 30 years on and off. I started in '76 running the darkroom in my elementary school in upstate New York (small town; 25000 people). My Dad got me taking pictures in 35 mm with his Leica and Nikon. In '84 I got a Canon AE-1 Program and in '88 a Minolta Maxxum 7000. After that I went digital with a Minolta DiMage Z1 and then (and still) a Sony DSC-R1 (AWESOME Portrait camera). After months of research, I purchased a Pentax K20D in Jan of 2009. I have never had a camera that is so flexible, user friendly and intuitive. I hope to learn from all the experts here and maybe offer a bit of my experience as well.
