Yep - I have one that is currently in my OM-4T. If I had more of them, they would be in my OM-2n and OM-2s as well, instead of the horizontal split image screens that are currently installed.
I swear that in those other cameras I have to turn the camera 90 degrees in order to use the split image effectively at least 25% of the time.
I'd really like to have one for my Mamiya C330.

I definitely DO turn my 90 split at times. Not a big deal for me.
I simply cannot judge the micro-prism well enough.
I wonder how many people rely on THAT.?
It is oriented correctly 100% of the time.

I use microprism more than any of the other focus aids. Some are better (easier to use) than others.

When i was 20-30-40......i "never" used them because i used the split.
I wish i would have tried it more often when my (near) eyesight was better.
Which micro-prism screen(s) do you like.?

On Nikon I’ve used the microprism collar on K and P screens. They are okay but not fantastic. I’ll bet that more microprism makes it even better. Better is that on the Ricoh Singlex TLS. That one “snaps” as it goes into focus.

I found my focusing screens worked a lot better after cataract surgery. Also changing the eyepiece diopters on my Nikons to a "0" - infinity focus - helped a lot before and after surgery. Nikons as they come from the factory are at 1 meter viewfinder focus - great when you are young. Even with nearsightedness correction glasses the screen became harder to see as I had lost accommodation, and so I had to sort of crane my neck to look through the lower portion of the vari-focal lenses of my glasses.

I "discovered" how much I like the microprism when I got a Pentax 67, which has a non-user replacable microprims only screen. I managed to find a micropism only screen for my Pentax MX, and I like it a lot.

Yeah, somebody said...was it Brian... the 35mm Split-Micrprism is hard to use because the micro is just a "Collar".
If the whole focus aid was a microprism circle it would be easier to use.

In Nikon that would be the G screen, I believe. 12mm center circle is microprism. All microprism is the H screen.

Yes you are correct again.
I have never used one. I am not sure what happens if you would use a 28mm with the G2 and a 150mm with the G1
Quoting the chart of 4 G screens......


G1 - For most Wide angle lenses with focal lengths of 35mm or less.
G2 - For most Lenses with focal lengths of 200mm or less.

I don’t have one yet, but a G2 is in the mail. I can’t wait.

For general photography I think you should be better served by focusing screen type F (Matte/Fresnel field with 12mm diameter microprism focussing spot. Briteview. Suitable for general photography. Similar to Type K; the choice boils down to whether you're used to the split-image or microprism focussing. Neither is really more precise than the other)
or
J (Matte/Fresnel field with central 5mm diameter microprism focussing spot and 12mm diameter concentric reference circle).

Personally, I went from K to J (it had pathetically small microprism circle) and than to P and now thinking about going back to K, but before that I would like to try H2 I already have but never installed it. Somehow most of my F's and F2s come with A and I'm not big fun of it.
B screen was great for 500mm mirror lens.

J… another great choice. Please don’t inspire me to buy more stuff. My thought on the G is low-light. Can’t wait to see if I can really live without the matte field.

I’ve been thinking of going back to K also. It’s packed away so deep that every time I think of it I consider just buying another.

Yeah, definitely agree with that. I'd love a microprism center with the since horizontal/vertical crosshairs. The diagonal split is not as good as the horizontal split for vertical lines, and not as good as a vertical split (not that anyone makes this) for horizontal lines, but is a useful "kinda good at everything" sort of solution.

Yep, that is one reason why the microprism screen is so good in my Pentax K2. It is an entire circle so it's useful. The whole thing snaps in and out of focus. Just having a collar is a waste of time and space. There is just not enough of it to be useful.

Yeah, at least for me......when i use a screen that is a combo of Split and Micro, when i try to use the Micro Collar, i have a hard tine seeing the whole collar at one glance. So i find myself focused on a pretty small percentage of it. 20% maybe.?
Obviously there are people who see the collar fine, i guess.?
It is a rather common combination. SOMEBODY must have decided that it works for a lot of users.

Cannot attest as to Nikon screens but my favorite type screen for my OM is the 1-10 screen, plain matte with grid. Always hated micro prism and split wedge focusing aids, except with very wide angle. Plain matte across the entire field with diopter matched to my eyesight. If the light is so dim that I cannot focus then its too dim to shoot photos handheld anyway. Maybe it is psychological but I find focusing aids on screens tends to draw my eye to them and makes it harder to compose.

From the picture it looks like the same microprism circle size as Type J?
Click to expand...

Type F has a 12mm diameter microprism circle.
Type J has a 4mm diameter microprism circle. The 4mm microprism is surrounded by a 12mm reference circle.
Both microprism circles are on a Matte/Fresnel field.
