Hi.
I am in the market for a DSLR and I don't have much experience. As I want to be able to use my camera in most weather conditions (I live in Norway), I want the Pentax WR. So I'm looking at K-30, K-5, K-5II.
I will mostly be bringing my camera on hiking with my dog and will be taking pictures, mainly handheld, of moving animals, landscape and nature in general, but I also want to be able to take decent sport pictures.
I am on a budget which means that I will not be able to buy any fancy lenses right away (unless something used incidentally appears for sale). I have read about decent sport photography with expensive lenses, but I am wondering about the performance of the standard 18-135 WR kit lens. (I think I will be able to get the DA 55-300 used too).
K-30 - it seems to me that this has an ok AF, but I would like a larger buffer in RAW. I would also have liked the top-LCD screen. That's included in the K-5sBut it is the cheapest model, and I here I would be able to go for a flash and some other stuff too.
K-5 - the AF of the K-5 is rumored to be dubious and I am wondering if it is noticeably slower than the K-30? Even in low light situations? (Like early dusk, indoors sports). It's not that much more expensive than the K-30 so it wouldn't really blow my budget.
K-5 II - is supposed to have an improved AF, but is it only effective in low light? Some reviews seems to suggest that. I would opt for this, but I am not sure if I can afford the K-5 II with the 18-135 lens (I think that's a smart move for an all-round lens), although I could get the 18-55 WR with the used DA 55-300 non-WR lens - I might be barely able to get the 18-55WR + 50-200WR kit instead).
So if I want as much versatility as possible (moving animals, action sports, landscape, nature, portraits etc), which of these should I go for? I'm only at a hobby level, but would like some keepers after use. I will of be able to add some more fancy lenses eventually, but I think I should play around a bit first to see what I really need before I decide on exactly what else I want.
So I wonder about this:
1) Are any of these able to do decent action photography (soccer, hockey, riding, birds in flight, dogs/horses in motion) with the 18-135 kit or other kit lens(es), or do I need better lenses for that or should I look at other brands? (try to getting a new or used D7000/7D or something). From what I've read all of these will do brilliantly with non-moving objects.
2) Will the K-5 AF suffice (both accuracy and speed) when it comes to action photography (since I can afford this with 18-135WR, and includes better buffer and LCD) or should I only consider the K-30 or K-5 II if I want to do action photography?
3) Is the learning curve of the K-5s much steeper than the K-30 for a newbie, so it would be much wiser getting the K-30 now and consider upgrading (maybe when some new models have come) in a year and I have a lot more experience?
4) I've read that the WR of the Pentax is much better than the competition, and it's probably hard to predict exactly what they can take before being damaged. But will it survive some light water spray from the ocean, light rain (will cover it better if "wetter") and will I be able to use it at all below -10C degrees? (I guess I have to acclimate it when going back inside in any case though).
5) Which of these will take the most decent videos? (Some says K-30 others K-5... and I'd like to have the opportunity of the mic for stereo sound..)
Thanks for any advice!
