everyone here is on the same learning curve..
even if they don't know it.
there is always another plateau to reach

If you go with a K-7, you may also want to consider the Sigma 50-150 f/2.8 EX DC HSM.

It doesn't get discussed as much as the more popular 70-200mm f.2.8 lenses. But, it's a smaller and lighter lens compared to the current 70-200mm f/2.8 offerings, and it's available at a slightly lower price point, too. Just keep in mind that you probably won't be able to use it on a camera with a full frame sensor without cropping, should Pentax offer one in the future (Sigma's DC series lenses like the the Sigma 50-150mm f2.8 are designed for cameras with APS-C size sensors). It doesn't look like it's available in Pentax mount yet. But, Sigma will probably offer it at some point.

You know, I thought this lens would be a big hit - the focal length is perfect for basketball. But I can't say I've seen a single indoor sports shot taken with it. That concerns me. Now, a contributing factor is: prior to clean ISO 3200 / 6400 you couldn't use 2.8 effectively indoors. And it's only the latest batch of cameras clean enough to give those results - and many sports shooters using those Canon 1d /50d, Nikon d3/700/d300 cameras are using OEM lenses. So not really a good cross section of cameras capable and sports shooters not using OEM lenses to test this lens out. On a spec sheet it sure seems good. But there are often vast differences between a spec sheet and real life. I would avoid using any lens for sports application without seeing first-hand photos of it's use for the purpose.

I don't have a lot of lenses, but I have a good 50mm f/1.4 and also a f/1.7. Both are manal lenses. My procedure would be to plan in advance on where you will get the kind of action you want. Then pre-focus for that distance and shoot when a situation takes place. By setting your shutter speed, the aperture, and the ISO in advance, and then testing them on a rather still subject at the planned distance, you will probably get a good picture. Try it with and without flash, but avoid the flash if you can get something usable without it. I think I would get a good picture at least a third of the time.
