Hi,

I have a Hasselblad 500C. To focus
I use the regular viewfinder it came
with the camera. I am assuming the
focusing screen also came with the
camera. (This camera I bought it
second hand).

I also bought from Kiev, the russian
middle format maker, a 45º viewfinder.
With this one, it is a bit harder to
focus. It is not as if with the regular
viewfinder may be a piece of cake to
focus with, but it is much easier!

I am blaming it all on the focusing
screen! Is there a "cleaning" solution
for the focusing screen that you may
want to recommend or is there a brand
name or model for a used screen that
you may want to recommend??

Thank you, kind regards,

igmolinav : ) !!!

It sounds as though the focusing screen is positioned correctly or the camera body is out of alignment. You may need a Hasselblad repairman adjust your camera.

When I had my Hasselblad, I got one of the cheap focusing screens you find on eBay, sold from Hong Kong. With the 45 degree split, I found it much easier to use than the standard one. I got something very similar for my Rolleiflex from Rick Oleson, but I don't think he does Hasselblad screens.

I find a very simple split screen can make focusing these things much easier.

While using Kiev 45 prism on Hasselblad, I found that is way easier for me to focus after I added -1 diopter to it. I'm wearing glasses all the time, -2.5 diopters on right eye. Took prism to local optical shop (the one where they rally know how to cut real glass) and they did it. Not expensive at all. After that it was way easier to use prism with all kinds of Hasselblad focusing screens. YMMV!

I don't know if they still do it but several years ago I wanted to be able to focus with the 45 degree prism finder and called Hasselblad. They had me send a copy of my reading glasses Rx and sent the appropriate diopter adapter.

Boy oh boy--working on Hasselblads, have I ever learned MY lesson on changing screens, and especially using off brands. Never again. You'd be surprised how the screen-to-mirror distance changes switching screens as if you're switching a band-aid. Especially with those off-brands. If you're happy, you're happy. But you were only lucky.

+1 for a split screen, the only way to go with a prism finder

OP MAY also have one of the old old old screens that is dark, fingerpinted, dirty, and damages.
The OLD OLD screens are very dark, and the prism makes the situation worse.
Hunt down a newer screen or just buy an accu-matt as they are worth it. Especially if you are using an f4 lens.

Oh... is you lens stopped down? Just asking, as it sounds like the whole rig is new to you.

OP has a 500 C so popping out the screen and replacing it isn't so straightforward.

IMO focussing a hasselblad takes a bit of experience and the prisms end up making things darker.

It is true that the best thing to do is have a Hasselblad experienced repair guy check it, especially for mirror alignment in an old body. If your main problem is that the screen is dirty you could take care to remove the screen and count the turns on the screws as you take them out and note which way up the two screens are. Wash the screen with a little detergent, don't use anything stronger than alcohol if you wanted to use a spirit solvent, you may lose the black crosses. Finally put it all back and using a loupe or magnifier to check the focus on the screen at infinity and at a closer measured distance, adjust all the screws the same amount so that the screen remains flat.
This is a not a technique that I would recommend to all because it cannot be accurate compared to a Hasselblad set up using factory tools but it may help you to see what improvements are possible so that you can see that having it set up to factory spec is worth while.
DON'T force the small screws, you really don't want to break them, trust me!
