Well, here we go again, revisiting my previous posts AF drive speed tests with a different camera, this time an EOS 40D. Like the last time, timing was approximated by filming the drive sequence at NTSC 60 FPS and counting the frames from the first frame before motion occurred until the first frame after the […]
As much as I swore off AF testing and calibrating, I’m back at it again. This time I’ve decided to forgo the sheet paper targets and build a target similar to the Lens Align. Now obviously, if you don’t want to spend the time building a target, a Lens Align is, to my knowledge, the […]
An post on Nikon Rumors lead me to a couple of interesting patents Nikon has received. One in particular that has the potential to bring SLR level autofocus performance to point and shoot cameras or pave the way for a mirror-less SLR.
