You already received some good advice. Let me add some thought.
Both the K-5 and K-7 are excellent cameras. You cannot be wrong with either.
The K-5 is the latest camera. Excellent users' reports. Expansive and fashionable.
The K-7 is an excellent camera with superb handling, viewfinder, WR and low ISO performances. The K-5 does as well but not better for all of these.
A weakness of the K-7 is the lwo light but there are several ways to have excellent low-light performances with the K-7. These include:
- with some in-camera PP, it is possible to get very nice shots either with in-camera PP (see
K-7 High ISO Success!)
- with some dedicated noise reduction software like Noiseware and NoiseNinja;
- with some fast prime lens.
I have used all the above techniques successfully, although I prefer the latter in the darkest conditions. The first two techniques are very easy to use and implement. However, in dark conditions, my preference is a large aperture prime lens with MF. (yes, MF). I work often outdoor at dusk and dawn, and at night times. I got my best results with my Voigtlander Nokton 58mm f1.4 MF.
Please note I do not talk of high ISO, but real low-light conditions.
Coming back to your question:
- choose a good lens; 'a lens is worth every penny' and it is an investment that will not loose its value;
- the present prices of the K-7 are nearly 50% of the K-5 price. That is, the K-7 is extremely good value.
- if you want to shoot in low light, consider to purchase (now or soon) a large aperture fast prime.
Unless you are addicted to get the latest 'gear', get the K-7 and invest in some good glasses.
Food for thoughts....
