>>3167854Trolling aside I have tried a Canon 70D with a 70-200/2.8 L non-IS and my own K-3 with a Tamron 70-200/2.8 screwdrive. RC airfield, relatively small subjects passing by with either the blue sky and some clouds in the background or distant trees, bushes and houses.
Subject arriving almost straight at the camera going sideways then away straight from the camera.
Continuous tracking and continuous burst. Both had around 70% hit rate as in keepers while the rest were missing focus. Canon wandered a lot between wingtip and fuselage while Pentax had either hitting the fuse and keeping it or losing completely until catching up again, few times latching on to the wingtip and not releasing until an AF button cycle.
Many others say the Pentax tracking is not as far behind as reviewers claim it to be and mostly limited by the lens AF speed. While I had my Sigma OS HSM lens it had a spectacularly fine job with tracking birds and planes.
So most of the reviews saying this is bad and that is sub-par, I always take it with a grain of salt. One reviewer actually claimed that at a horse race (jumping gates kind) he couldn't get a sharp shot with the K-1. A week later someone released a series of shots from a similar horse race and a motocross race with mostly straight on tracking shots and the focus was on target. Turned out the reviewer didn't even bother to set up the camera properly.
Oh, and I read up on the original comments, why are you responding to obvious bait? Well, I did too but I thought it was a Pentax beating from one of the shitposters.
