I changed my focus screen on a DS about 3 years ago (same time I bought camera). I put a split image rangefinder in there and it works great to about F4, if you line your eye up to the finder just right, even F5.6 can work. The finders are easy swap out, you just need a pair of large tweezers or a small pair of needle nose pliers to grab the little tab of the screen. I bought my third party screen from a seller in china on ebay.

For me, matte focusing screens were only useful when using a tele that was so slow that half of the split images blacked out. On Nikon SLRs in the 70's, it was called a K-screen. To give you some idea of how ignorant I am of modern dSLRs, I didn't realize that the user could change screens until I went to the Katzeye site and downloaded the instructions (!). User-changeable screens was such a perk back in the 70's, if the screen was changeable, the customer knew it as it was highly touted in the specifications and user manual. I haven't fooled around much with histograms in the theater productions because the lighting changes from minute to minute. This is one of those rare occasions when automation seems to work far better than my futzing with the controls. I get a spot reading on the subject's chest or face, and keep the shutter button partially depressed. I do have to experiment a bit more with the green button feature, and will pull out my Magic Lantern book this evening to get a better grip on some of the program features. Is the Katzeye relatively easy to install on the Pentax? I've never had an issue with screen swapping on Rolleiflexes, but they are big and easy to fool with.
