Like Craig above, I use the Pentax 67II primarily for rail photography. The Metering prism incorporates matrix exposure control and aperture-priority capability in addition to average and spot. Exposures are usually right-on and the handling is exceptional. It is very possible to get very sharp handheld images practicing proper technique. When trackside chasing trains you don't often have the luxury of setting up a tripod. For color, I use Provia pushed to 200 and also shoot Ilford HP-5 at 800-1000 and send it off to DR-5 in Denver for transparency processing. It's a great camera!
