Originally posted by LeDave I don't want to have to buy and sell buy and sell all the time just because there's another body that's better than the other; no it's not that at all, it's that the K-x is so much better than K-7 in high iso IQ. They both came out this year, and I was really hoping to upgrade from my K-m to a K-7, I really had that down and on lock. But the K-x came out and it made me a little disappointed in the K-7 and now I am completely lost on what I really want. I don't want to keep my DA* 50-135, DA 35 Macro LTD, and DA 21 LTD in my bag for half a year or longer just for a newer body to be announced that will have the same if not then around the same high ISO IQ that the K-x boasts with the body that the K-7 has.
The way technology is going, the longer you wait the better value you are probably going to get out of your camera purchase -- that's true before the K-X came out and I suspect it will be true after the next camera arrives, as well. The only problem is you have to bite the bullet sometime or you'll miss out on all those great pictures you could have taken
My take on the K-7 now that the K-x is released is that it would have convenient if the new Sony sensor was in the K-7 because that would have resolved pretty much my last major complaint with the camera -- that shooting at ISO1600, while it can produce good results, is more annoying than it would be to deal with than good out of camera results. As a result, as I am looking to buy a second body for shooting weddings, I will probably wait to see what the next Pentax camera can do in terms of high ISO before I decide what to buy. Either that, or I'll wait to see if the price drops on the K-7 and just buy another one.
This said, from ISO 100-1600 the K-7 takes great photos, with wonderful detail and color and it is such a solid, well performing camera that I haven't regretted buying it for a moment even when I bought it at its highest price. If Pentax were to come out with a full frame camera, or if I bought a camera from a competitor, I'd still likely keep the K-7 on its own merits.
If anything, instead of reacting negatively to the K-x's better high ISO results, I am optimistic about what they portend for future Pentax cameras.
