I'm not a sports photographer. I just shoot some action now and then for fun like most people. But if I had to choose between a camera that could only shoot, say, 5fps but had killer fast AF and 3-D tracking vs a camera with, say, 12fps and slower AF, I'd take the 5fps/fast AF any day.
...and if you were to choose between RAW and JPEG on the same camera for sports? Knowing that the JPEG engine isn't that terrible, and AWB is reasonable on the k-3?

Use it as you like old boy. But I would recommend RAW and Lightroom and/or CS6 with a bunch of plugins to get the best out it. Especially dealing with noise and at the same time extracting detail.
I do. 90% of my shooting is RAW, processed through LR. I wouldn't be giving my DA*55 or FA*24 their proper respect otherwise. But when I go to watch my friends play volleyball or football, I rather lose the dynamic range and gain the additional frames.

I'll have a go at this Jin, only thing is all my AF lenses are all screw drive. Reckon I could do with something that can focus faster.

You have set me a task.

To be honest - I am still not recommending the k-3 for sports. I wouldn't, and I wouldn't recommend mine for sports. But you know what? As a recreational user, I gotta make my camera do its best for whatever my situation is. That's why I never really comment how people use their cameras - because if it works for them, all the power to them.

Definitely, it's a great camera. I've bought three of 'em!

My only real issue is with the K-mount and M42 . . . I can't stop buying old Soviets.

this red detail problem is a Bayer issue
This issue has been extensively examined, debated, tested etc here before. It tends to be more of a camera processing issue, specifically the level of chroma NR applied. Reduce chroma NR, red detail comes back.

I only shoot RAW and post in LR5.3 and CS6 using Nik or Topaz as well. It's still not great when it comes to reds.

Long exposure noise, even with ISO set to 100. Terrible?

Anyone?

I made a number of long exposure shots using K-3 : I haven't noticed any noise that would affect the image. If you are interested, I can post some samples.

- RAW Therapee, no corrections at all. 13 seconds. F 5.6. 18-55 WR kit.

- OOC JPG. F5.6, 10 seconds. ISO 200. 18-55 WR kit.

If you don't trust JPG, I can upload one of the RAWs.

K-7 somehow is regarded as the world's noisiest camera -
The K-7 was considered bad mainly because it was worse than the K-20d.

It was the same sensor with a 4 channel readout to enable video and it really hurt it's photography performance.


According to DXO the K-3 is worse than the K-5 or K-52.

Not massively worse though. I suspect a fault here.

I looked at the SNR curves and the K3 and K5 II lie right on top of each other. The K5 has a little more dynamic range, but noise-wise the two cameras are the same at same print or viewing size.

Using Stagnant's ISO12800 PEF, I've run a comparison of the NR5 algorithm in the new SilkyPix 6:
