Originally posted by Catscradle At any rate, I can get the K-5 and D7100 at the local shop for the common prices on the internet (plus taxe, grrrr). However, they've aggressively priced the K-30, probably because of the introduction of the K-50, and it does tempt me. I can get the K-30 18-55 mm kit for $500.00 or with the 18-135 kit for a little under $900.00. Those prices really draw me, but I'm thinking in a very short time I'll be wishing I had the K-5 II (or the D7100).
I just went through the same process. I went with the K-30, and after a couple weeks, I wasn't satisfied. Two main reasons: first, I do some race photography on the side, and after 900 shots in a few hours, I had almost gone through my third battery. I'm not suggesting that you'll be doing that much shooting, but if you've got grandkids or other things in your life that you want to shoot a lot, you'll notice the difference. Second, the lack of a battery grip. I don't shoot with a strap, and really noticed how small the K-30 grip was after swinging it around.
So I just upgraded to the K-5ii + grip (I went with the Pentax grip, rather than knock-off, and I'm already aware of where my money went. It'd be nice if they knock the price down a bit, but the grip is great, weather sealed, etc).
The biggest lesson for me is that I found that I had my heart set on the K-5ii, went with the K-30, and regretted it. If you know the body you want, just go get it. The K-30 is great, but its not a K-5ii (or D7100).
As far as the D7100 goes, it was quite simple for me. K-5ii + Pentax grip and Pentax WR lens = go wherever I want (and as a climber and former guide, that's a lot of places). There's no way I'm bringing a D7100 on an overnight trip where the weather might get a bit nasty.
Hope this helps
