Originally posted by Racerdew I do a fair amount of outside photos at low ISO and indoors I am using my flash most of the time. And the better viewing screen is a big plus in out door light. Some times I second guess my shot even using the histogram because I can't see the display in the bright sunlight. So those two factors are probably the strongest points to why I would get the k-5 IIs. If not for those two factors, I would get the k-30 and maybe the 300 mm lense for fun.
My experience with my K-r is that sometimes I get some real soft focused images and some of that is the Tamron 10-24 lense. I would like to do less sharpening in PP so the higher res and focuse is desired. I am hoping to improve my work with sharper better images.
I originally moved "up" from the K-x to the K-5. On Tuesday I received my K-5 IIs.
Based on your description of your needs and shooting style, you need the K-5 IIs. The K-5 is not a big enough step up.
Based on my experience so far, especially when setting up the AF fine adjustment on most of my lenses, I think you may begin to clearly differentiate which of your lenses have higher resolution and can "keep up." This helped me see how good my FA*85 really is. I think that's why Adam's been using it so much for his testing. It's not that it's perfect, it's just that some of the other lenses seem to be falling back a little bit in relation to it. But this is hardly a negative - it means that the camera is getting the most out of each lens.
I think K-5 IIs will also help you decide whether the Tamron 10-24 is really holding you back or not. The DA12-24 is probably better, and I have hopes that the new Samyang 10mm prime will be good when it comes out around the end of the year. While I usually recommend a quality lens over a camera body upgrade (especially since Pentax' entry level bodies are so good), in your case I think you may need to get the K-5 IIs and try it with your current lenses.
Otherwise, if you already
know you need a better lens (for example the Tamron 10-24 is your best and only wide-angle lens), don't buy
any new body, and upgrade the lens first.
