Bought this Pentax K100D after buying the Canon G7, so far Im delighted with the results... ISO 200-3200 no noise at ISO 1600 however begins to get very noisey around the MAX JPEG ISO 3200, However, at ISO 3200 RAW useable in RAW MODE; but ISO 1600 will cover most situations Ive been in without needing to use RAW ISO 3200 Mode. (Great to have for low light) also the (SR) Shake Reduction, which is actually great (solid image stabilization)... Excellent feature, the main reason why I bought this camera was because of (SR), and very low noise all the way upto ISO 1600 then proccessed in RAW ISO 3200 is still very useable.
The camera Operating System is very well thought out, and can be displayed on the 2.5 inch colour LCD at the rear... (very user friendly, very intuitive), I did not even need to use the Manual, so if you are looking for a Quality camera, with 18-55mm kit lens, to start shooting without needing to read reams of paper, don't worry, this is the camera for you.
I have the K100D set at (auto) for meanwhile, and it does take lovely clean, sharp, and silky smooth pictures. The auto focus is spot on.
For a mere £299 for a high spec dSLR camera, with image stabilization, what a Bargain.! (the price may have rose a bit since I bought, but can still be bought for £299 online if you (google).
Another bonus is that the K100D uses 4xAA Batteries, which mean you can use Alkaline AA, Lithium AA, or Rechargable AA, so you have a choice, beats propriety batteries hands down.
Thanks for reading...
