I've used this the last two times I cal'd my lenses. Works well.

DSLRKIT on Amazon, about $5.
Definitely use a heavy tripod for your camera and a cable release. Use lowest ISO (100 ON K-1). Use off camera flash.Use viewfinder, spot focus. Spot focus square should be slightly smaller than target area square.Please note that, for manual lenses, a light touch is a must. Try not to move or bump the camera. For both manual and auto-focus lenses, first place lens at infinity, then adjust manually or auto-focus from there. Repeat 2-3 times. Verify correct adjustment by re-checking in 1-2 days. See AF adjustment tool procedure on this forum.
