For the most part, most of us who shoot beside those guys find the same thing. Sometimes I get the best shot, sometimes they do. I seriously have issues with folks going on about "you have to have this AF or that lens" or whatever. What you have to be able to do is use what you have. 8 years ago I was using a Sigma 70-300. I stopped using it when I realized I was being limited by the limitations of the lens. It took me about 5 years to out grow that lens. I began taking pictures where the resolution of the lens was affecting my IQ.SO many folks think they need to start with the latest and greatest. I'm kind of the opposite, learn to make the most of cheaper glass, and when you get better at shooting, you'll know how to use it when you buy better. And the most expensive glass and AF, IMHO it's not even worth owning unless someone is paying you. Better to start low and understand what you have before you move on, than to buy top of the line and never really learn to use it.

Most people are quite close to small kids. The difficulty is keeping them stable in the frame so AF can work at all and pressing the shutter release without moving the camera too much. I'm convinced a lot of folks blame AF because they aren' skilled at doing these two things. It's not really an AF problem, it's an operator error problem. Just because your kid is running around does' mean you don't have to do triangle bracing with your elbow and control your body movements. Also many people are trying to get kid images in very poor right.

It's just so sad seeing people blame their camera when their lack of success has nothing to do with the camera.

K-3
FA 50 ƒ2, 800 ISO 1/50 in the middle of a cartwheel... terrible basement lighting.. any softness is motion blur so what kind of movement do you need a Canon for again?


Anyone who says they can't get images of their kids because of Pentax AF, I'm not believing them until they show me they know the difference between bad AF and motion blur. Especially those using non SR cameras.

There are four possible issues.
1. Subject motion blur. (The cameras AF system cannot help if your shutter speed is too slow.)
2. Camera motion Blur. (AF cannot help if the camera is moving more than SR can correct.)
3. Poor tracking technique, focus on something other than subject. (NO tracking system in the world will know exactly what you are trying to focus on. You have to get it locked in the right place,)
4. Camera AF can't keep up. (Often this has to do with 3, your tracking motion didn't keep the subject in the frame, and the camera had to re-aquire the subject.)

For people having trouble tracking their kid, there's at least a 75% chance they are confusing camera error with operator error.
The fact that you have a kid and own a camera doesn't make you an expert at figuring out what went wrong when you don't get the image you wanted.

Ian and I once got into it over dos running straight at the camera. I think I to 5-7 with the 3 or 4 closest to me out of focus, he got 12 in focus. It's not that you can't get it done, it's that cameras with AF designed for action increases your odds.

Ian was shooting a D750 if memory serves me well. For the difference in price, I was really happy with my K-3. After all, how many images of your dog running straight at you do you really want? :D
