Hi, I am very interested in one for my upcoming D200 also. I am wondering if there are any focus/exposure problem with AF lenses vs the stock one?

Thanks Alex for bring out great products!

Alex, two questions:

1- does your screen have also the microprism collar, or only the split-screen?

2- would it be possible to have a screen only with microprism circle in center, no split screen? I don't really use the split screen, while I find the microprism circle the best tool.

I am interested in a screen for the old 5D.

thanks!

There are no focus problems with split screens.
However *** i am not sure with Nikon *** the spot metering may be off.

I currently only stock the splitscreens with microprism (mainly Minolta splitscreens), however any focus screen can be customized. If you want a screen without split screen, could you refer one to me and i can see if i can get it locally and then customize it.

Olympus i have, but need to know the specific model. Oly E1 is hard to make.

Panasonic L1 i need to ask.

And what about calibrating? Does it need calibrating by shims after installing? I have cheap chinese split screen for my Nikon D80. Do you think that your screen has better quality than my? Is it worth me to replace it for yours?

Alex, I don't know of any existing product. Katz Eye used to make screens with microprisms circle only, but they don't make it anymore.
What my screen would ideally be is like this:



As you can see, there would be a central circle full with microprisms (no split), and two lines that cross in the middle, to help with keeping camera straight.

If possible, please find a screen like this (or if you know someone who produces screens, please ask him if it's possible to have it made).

I've seen your message too late and I'm not home for the weekend to check but I am pretty sure the Minolta SRT101 has the screen you need (microprism only and *very* bright).

I think that Katz Eye screen was modified from a Canon EC-A screen intended for the EOS-1 series camera (film or digital) Wink

Using the Canon Ec-a's a definite possibility. "Focusingscreen.com" also use the Ec-a Canon focusing screen, which is a laser matte, with a microprism centre. The list of official compatibility (from a quick google search) is: " EOS 1Ds, 1Ds MK II, EOS 1, 1N, 1N-RS, 1V, EOS 3 and D2000".

Installation will be very tricky for the Olympus 300/300/E1 and the Lumix L1.
Therefore, professional installation is strongly recommended.

I am with Orio on this one! Microprism only would be awesome.
Canon EC-A or Nikon F6-J are both microprism only Very Happy

If you can make one for Canon 40D, let me know!

Hi Alex

+1 for Microprism only.
If I could have a screen like the original Contax RTS it would be perfect.
Even though that one did not have the segmentation that Orio brings up (that of course would be even better).

The split screen in the example you sent me for review really is distracting upon first use.
I need to spend more time with it before I write a full review.
This I can say. It is accurate to f2 Very Happy.
I get the same focus as my happypage HK adapter using Planar 1.4/85.

Once to f1.4 it seems that the micro callar and split screen front focus a bit ( the AF confirm chip is not any better at wide open.

Can shimming help this? I don't think I would bother but maybe some guys would.

I found another one- it's for the Nikon F3. It's a G1 screen and it's supposed to be ideal for low light situations. This may be a good alternative. I found one on ebay for $9.99 Click here to see on Ebay

I would be a willing lab rat on this Wink

I think it's physically impossible for a focus screen per se to be BF or FF. My guess is, like the case was with my KatzEye screen in my K20D, if it's front focusing, that's the problem with the camera, and the only fix for that would be to use shims (or, different thickness shims).

Hello Orio
ias mentioned by others ... there are a number of options available, from Leica, Contax, Nikon and Canon, prices are EUR50 ~ 90 range, depending on the cost of the original screen.

So you mean that I can take any screen, from any 135 format camera, and you will adapt it for the 5D?

If you're handy, you can even do it yourself.

After reading http://yipal.blogspot.com/2008/10/fitting-k3-focus-screen-to-d70s.html, I saw 2 defect cameras (Pentax ME super and Spotmatic) for 6 € on the Bay and sniped them.

When they arrive, I'll have a try at screen cutting ...

P.S. I'll check tonight my Minolta SRT101 screen

As I though the Minolta SRT101 has this kind of screen :



The Spotmatic is more or less similar :



Microprisms only in the center

Thanks Jieffe
it costs too much to buy a camera only to take out the screen Sad

I have some old Praktica, I will check their screens, what size must they be to fit the EOS 5D (first one) ?

If I can remove the Spotmatic screen without damage, it is yours Smile

Praktica screens are darker, I think you will be disappointed.

Although I haven't used one in a DSLR, I've looked inside a few Voigtländer VSLs and I did like their split diagonal prism a lot. If there isn't a problem with brightness, that would be my ideal focus screen, i.e., split diagonal in the center and microprism collar around it. Some kind of line would help with horizontal Very Happy
