Originally posted by Lambic I had a look through the K-70 review and they really slam it's AF performance, particularly for sports. I happen to have a couple of athlete kids that take part in a number of fast sports like skiing, biking, competitive swimming and ice hockey. Is the K-70 really that poor at AF for sports subjects?
Well, I've got the K-S2 which has the same AF as the K-70. It's well behind the AF of the K-3 or the KP in speed (especially with screw-driven lenses) and accuracy. But if you use the DA 55-300 PLM the gap is narrowed. To put this in perspective, either will be streets ahead of the K10D.
The other thing for sports is that the K-70 has a slightly faster frame rate than the KP. (Both are well behind the K-3 in this regard, because it has a faster frame rate and a bigger buffer.)
Another big difference between the K-S2 and KP is in exposure metering, especially in matrix mode. The KP also has better SR. And a host of other features not found on the K-70.
The ergonomics of the KP are polarizing. Personally I don't find it as comfortable in the hand as the K-S2, let alone the K-3. And while it has a host of dials and buttons, it's a bit cluttered IMO. I also prefer the flippy screen of the K-S2 (and K-70) to the tilt screen of the KP.
Overall the KP is a more advanced camera, but the K-70 is a whole lot of camera for the money.
