Split screen

Anyone swapped in a split screen to help with manual focus lenses ?

I used to really like these in the 35mm days

I have a Katzeye one in mine. Accurate manual focusing on a DSLR is virtually impossible without one. You'll find quite a few other people have done the same, mainly so that they can use old manual focus lenses. I think very few go cak to a plain screen after trying the split prism or other alternatives.

They will work fine, only the light meter will be off a bit.

I have a Katz Eye in my K10D which I purchased after first buying a cheapie offf Ebay. Others have had good luck with the Ebay screens, I didn't. At around $25, they're worth trying. The only metering that gets affected is spot metering. I find it essential for using MF lenses. Having 2 camera bodies, my K10D has become "manual glass camera" which is why I haven't added one to my K5 yet.

I have 2. Both are from Jin finance, one is a single diagonal split, the other a dual diagonal split. The dual split seems rose accurate on focusing because it displaces a "slice" that is quite obviously misalligned when out of focus

Sounds very interesting, got a link to where to get that screen?

I have half a mind of seeing if an *istD can be so converted....

One of my 20-D cameras has a Katz-Eye split screen, and it really helps a lot with focus combined with the viewfinder focus emblem. I keep this 20-D set up for manual lens, A50mm 1.7, Auto Sears 135mm 2.8, Helios 44K-4, and others. I do not have any experience with other brands of focussing screens, so can speak only of the Katz-Eye, and I can definitely recommend it. My technique is to use the split-screen to get as near to focus as possible, then turn the focus ring very slowly while watching for the viewfinder focus emblem to pop in. While standing for hand-held shots, I sometimes do not turn the focus ring, but instead move my entire body slightly forward or backward to bring the camera into focus, sort of like locking a macro lens and moving to or from the subject to attain focus.

Try this
Dual Split Image Focus Screen 4 Pentax K10D K20D ist DS | eBay

The K10D screen and *istD screen are interchangeable. I have this in my *istD

If you are at all mechanically adept and can work with s,all items it takes about 2 minutes to change. Just get a clean AA, some tweezers and read the instructions about changing focusing screens, or search here on the forum for clues

I got my first manual lens for my k2000 and I found that I couldn’t focus it so I bought one of those $20-dual split-ebay viewing screens. I didn’t do a good job installing it and took a couple of tries.
It seemed like I was putting a lot of torque on the latch and I wasn’t sure if the shim was to stay in or (as I read somewhere) go. I also had an issue with dried out rubber around the latch crumbling after I poked it while opening the latch for the third time.
It works well, but I got some dirt on top and scratched the bottom some. I’ll do a new one soon.

Attached are some tests. I had strange lighting and I adjusted levels. my conclusion is that it’s good enough for 3.5 but front-focusy @ 1.7

Before I get the new one, I want to try shimming this one with tape to find where it’s optimal.

I tried one for about a week. It made it easier to focus on fixed objects, but harder to focus on moving ones.

The best focusing screen I have tried so far is the EE-G (newer one is EE-S) from Canon.
Had the K3 screen before but it affected spot metering and was a bit off and had to be shimmed to be good enough (and there are quite a few reports of this).

Theres a thread going about in this forum on the EES screen.
Perhaps its worth it to have a look at it before you spend the money.
