I've installed a Oleson screen on my wife's Rolleicord, which is brighter but I found the visible rings disturbing. Also the split prism isn't good to work with when you do not use the loupe
I have a rolleigrid in my Flex 3.5E which is kinda a good balance since the rings are less visible and I get to see the center of the frame without disturbance. It's not as bright as the replacement screens tho.

Hi there,

one question regarding the stock screen of the 2,8D and replacements : I really liked the way the 2,8D screen made the focused object "snap" or "pop out". Now I have a 2,8E and the screen is much dimmer and does not have this "snap" focusing.

Is there any of the replacements screens mentioned above, which offers this kind of "snap" focusing method? I think any split screen or simpilar stuff will disturb me in focussing.

I am thinking of getting the BrightScreen From Oleson cut down to my Rolleiflex 2,8E but not shure if this screen offers "snap" focussing.

Brightness and focusing snap work against each other. I tried a RB67 screen (the A one, which are supposed to have the best 'snap') in my Cord once and found it horrible. Yes, it was nice and bright... but very hard to focus! Compared to the old plain glass screen there was nearly no snap at all. What good is a focusing screen that you cant accurately focus? I quickly changed it back to the original screen.

I gotta agree with Miko. When I got a 2.8D and thought the screen was a bit dark, it needed an overhaul so I sent it in and it was recommended that I go with a Maxwell Hi-Lux screen. Once I got it back with the new screen, it sure was bright, but after about a year, I sold it because I found it difficult to focus. I missed everything else about using a TLR, so I picked up an Automat. The screen is certainly dark, but man does it pop when the image is in focus. I'm gonna stick with the original screen in this one.

this is exactly what I saw on the 2,8D (stock glass screen) -> yes, it is kind of dim but it pops in so awesome...
Man, now I am asking myself where to get a 2,8D glass screen to replace the crappy 2,8E plastic screen. Any suggestions?

When your viewing lens is clean and you have a mint mirror, the plain glass screens aren't even that dark (in my opinion). Ok, it get's hard to see the corners in dim light interiors at night... but in such light you get plenty of other problems to care about then your screen corner illumination
I also find it even harder to focus on the fresnel parts of a bright screen, all snap really disappears there.
Bright screens are maybe great if you are doing much architecture or landscape where you are working stopped down at mid to far distances, don't need to focus as precisely but you need ultimate composing precision (wouldn't be a SLR better for that anyway?). If you are shooting a lot at near distances and/or wide apertures, go with the darker & more precise focusing screens.

I like your reasoning, and find that you are right at least for me. I still prefer the split screen (I have poor eyes) and the Fresnel part is never used.

I recently bought an older automat Rolleiflex. Even after cleaning the viewing lens, reflex mirror, and top of the focus screen, the view was super dim. I was hoping to order a standard Oleson screen, but since he was out of stock and I got the camera for a good price, I decided to go with Rick's brighter screen, which he modifies to fit older Rollies. I'll report back.

It seems like my comment is invisible
You should at least try a Rolleigrid!
It's not a replacement but something you put on top of the ground glass. You can easily take it out and put it back in to your needs/lightning situation.

UPDATE: I thought I'd pop back and update one part of my original test. The screen that I say is similar to a Rick Oleson screen is no longer the type of screen that Rick Oleson is selling. The screen Rick Oleson is now selling is about the same quality of the Mamiya screen in my samples.

His screen has a large microprism center area. I have a sample on the way to me along with a Mamiya microprism screen. I will do a new comparison of various screens once these new version arrive.

Anyway, to be clear- any reference to the jinfinance screen as being most likely an Oleson screen is outdated.

I have a Rolleiflex T which has a plastic split image screen. I just purchased ($80) from Rick Oleson a plastic screen but this has a Fresnel focus center. I really wanted the split screen but they don't have one for the 'T'. My new screen is way better for viewing, much brighter, the focus spot is very good too. Better than my SLRs and Pentax 6x7, so I can live with the Fresnel focus.

Are you sure it is fresnel? That would be a series of concentric rings.and is a light system, not a focusing system. Microprisms are small triangles that snap in and out of sharpness with focusing. I was under the impression that Rick's screens have microprisms.

If you still want a split image screen, I have a Mamiya one for sale. But it'd be $90, a bit of a hit after already buying a nice screen from Rick. Drop a PM if you want to discuss.

You are probably right, I don't bother to know much about these things: camera gear, lenses, or focusing screens. I do know that the screen does have the large area with concentric rings and I suppose Microprisms is the right word. Thanks for the offer but I'm going to get used to this screen. And thanks for the correct wording on these products.

These newer screens are BrightScreen Branded Replacement Screens they had made up to their specification prior to Jim Lakey's passing.

These screens are quite good and inexpensive when compared to the Maxwell. Also NOT AS SOFT as the Maxwell. I use these BrightScreen in several of my Rolleiflex TLR and Rollei SL66. You will be happy with these screens. Made in Japan and not the cheap junk from jin finance in China.

Thanks, I hope by 'you' you meant me. So far I like it, but I haven't developed any film yet. Although by measuring the distance it seems the same as my old screen.

Thanks for presenting your tests.

Just a question, how much does the mirror on each camera affect the image?

For my test, you can assume that each camera had a clean, most likely new, mirror. I almost always put a new mirror in a camera if I have any doubts. Hmmm... thinking back, yes, each mirror in the test cameras was recent or new (six months or less).

In general I would suggest that people put a new mirror in if there is any oxidation or fogging. marty1107 on Ebay will make you any size mirror you need-

I once made a couple of reflector telescopes, Newtonian, and after grinding and finishing the lenses I had them, in a vacuum, coated on the front with aluminum. An outfit here in St. Paul did the coating.

As I understand, silver was used on some of these old cameras for the coating on the front. And silver, well it tarnishes over time!

Thanks for your answer.

Just checking, but are these the only readily available focusing screens for the interchangeable hood models?

1) Maxwell
2) the new ones from Rick Oleson
3) the Chinese "Super bright split image" focusing screens on eBay (these are the Jinfinance screens, right?)

How's the new Oleson screen? Has anybody gotten the unbranded Chinese screen?

I would like to try a screen with good focusing snap on my 2.8D Rollei. I don't think I need a split image. What I'm getting so far is that the maxwell is not the best screen if you want to focus anywhere on the screen, rather than with the split image.

If brightness and focusing work against each other, I would rather go with optimal focusing. I'll use it mostly outdoors in good light. What is the best screen for focusing "snap" in good light? The original from Rollei? And where do you get it?

OK, here is a report after a few rolls with the "new" camera.

I have the Mamiya "A" now installed in my 2.8D.
Honestly I can say it's the best combination of brightness and fine focus capability so far.
I've used the Maxwell screens in the past and find the Mamiya is a touch less coarse and gets closer to a classic Ground glass in focus "pop" while being much brighter out to the corners.
When I had a mamiya screen in a camera in the past, it must have been an older one from the C-series TLR.
This "A" screen looks fantastic!

One drawback on installing it in the 2.8D or other fixed WLF models is one must forgo any factory framing lines.

I like 3rd segments if possible on my screens but with the Fixed hood models only the actual focus screen will fit in. (not sure how a rollei with removable WLF would work).
With the Mamiya screen, the glass cover has the lines on it and it may not be installed as it ruins lens culmination.... (you run out of adjustment).
If one tries to put the glass on the top side of the WLF frame, the WLF will not close properly.
The only option would be to scribe on the acrylic which I'm not daring to do at this point.
So a point is, Don't bother trying to find the Mamiya "checker" screen... the standard "A" or usually inexpensive "A3" will do.

I think I paid $40 for a new A3 screen a few years ago. It's been sitting in a bin until now.
Looking on ebay, there is a seller who has new A3 screens for $49 BIN.

I'm bringing back this thread, I just received a Mamiya RB67 screen #4 with a
Microprism spot, and after lining up the old Rolleiflex screen with it and marking
it with a pen I Dremeled the Mamiya screen to fit the 3.5F. All I have to say is
it's a great improvement at really bright. Now my 3.5F and my 2.8C are done
with new screens. Thanks Dan for the review of all the screens they were a big
help.

I have the same screen in my 2.8E and I have the no.3 rangefinder spot in my T. So far I’m liking the rangefinder better. If I just want to look down and focus using the surface other than the center spots it seems like the rangefinder is a bit easier to focus. I think it should be the same so maybe it has something to do with the hood or diopter. I’m finding both very useable though. The original screens are only good enough for me outside in bright sun.

Hi Steve, I think your right, the microprism which I got is good but finding a
split image rangefinder would be better. Here's another thing, since I got the 2.8C
I love the focusing in that better, why?. It has a built-in diopter correction, when you
lift the magnifier you could adjust the height of the lens separately to fit your eyesight,
it's really sharp, but my 3.5F's it only goes so high where I have to lift the eyepiece
further up for it to be clear. It is what it is I guess.

Have you used a Dremel for this? I find it can be pretty messy, including spitting hot semi-melted plastic all over the place.

By the way, the answer for Rolleis without movable magnifiers is to get diopter lenses. Contact Harry Fleenor to see if he has what you need. If it's a question of close focus. go to the drug store and play with reading glasses to see which number works best/

Yes I have, my other screen I cut with the Dremel, and about the diopter for the F.
I wanted to use my eyeglasses when I focus my camera's like my 6002 and my
2.8C for some reason I can but the way the F is made it's blurry to me and I have
to lift the magnifier higher then it's clear, so I have a junker waist level finder with
the magnifier bent higher in which I could see clear.

Do you use a diamond cutter? The only issue I have had is the plastic will form a ridge alone the cut edge. This can be cleanly snapped off when cool.

I was haveing problems with mine too. I had to pull my eye away from it. Then after getting a new prescription, which has better reading section I can see well in both my T and E Models. If you talk with Henry let us know which diopters he has.

I've used three methods to cut screens-

1) Score and snap. If you are experienced in doing this with plastics, you'll know what to do. If not, best avoided. 220 sandpaper wet sanding cleans up the edges nicely.

2) Bandsaw with fine tooth blade. Again sand edges.

3) Laser cutter. Protect surfaces from smoke with app tape.
