CiroFlex ground glass dim/Replacement?

Well, it seems that I am enjoying a little break from the pace we set last Spring. Eschewing the digital world for a little bit, I am having fun with my remaining film cameras using Double X!

A few days ago, I took the CiroFlex viewfinder off and pulled the ground glass to clean it and also, I cleaned the fogged mirror and the lens. It is still half as bright as my Hassy 503cxi, though.

Indoors, it is barely possible to focus so I tried a spare Hassy screen and it brightened it up so much, I was quite excited. However, the focus needs the screen to sit higher, much higher, like 1/8" or 3/16" or more above the original screen. I am not opposed to using the Hassy screen with its smaller footprint, but shimming is not something I am experience with...

So, is there a source for a new ground glass screen that would replace the one in my CiroFlex? The camera takes great pictures (when I remember to wind on after taking a shot!). It would be cool to be able to use it as it fits in my Billingham Leica bag perfectly and is light, light, light!

Any ideas are appreciated in advance!

I have problems with these viewfinders too. I got a bright new one for $80 from Rick Oleson. It was for my Rollei, I also bought one from him for my Ricoh Diacord G. You might check his website to see if he has one for your CiroFlex. I like a split screen finder but he didn't have one for either of my cameras.

Cool! Interesting and yes, I will check with him!

Thanks so much!

The mamiya “A” screen for rb/rz67 is excellent.
It’s thin and so can be shimmed to focus perfectly on most tlr’s with a few strips of tape.
The screen is for a 6x7 making it a large enough piece of stock to get any 6x6 focus screen from.
Just trim it to fit and use your old GG on the film gate to match focus perfectly (tutorials online).
Ricks Screens are bright but I find them a bit too coarse for critical focus.
My eyes are shot too so take that with some salt.
Many like the screens from RO very much.

Thanks, Andy! Having fun today playing around, but I really would prefer a Rolleiflex, LOL!!

In my Ciroflex I found that the silvering on the mirror was deteriorating and found a replacement on Ebay for $7. It made the viewfinder image much brighter.

As far as focus adjustment is concerned, the viewing lens on mine is easily adjusted to correct focus; a simple locking ring and a threaded lens mount. I expect there’s more than enough travel there to compensate for a different focus screen thickness.

Update:

Rick emailed some information back and YES! he can supply a screen for the CiroFlex. Reasonable prices, IMO...

For now, I got the Hassy screen in, focus dialed in as best I can do indoors at night and it will do for awhile. Tomorrow, I will fine tune the focus in the sunlight.

One problem, the screen needs to be fixed semi-permanently in the WLF. There is no provision for the screen to use the original spring retainers because the original ground glass is on 1mm thick. Right now I have it taped in.

Maybe I can use some window caulk/permatex/etc. but I am looking for hacking ideas.

Update 2: The focusing is really nice with the Hassy screen...however, there is just no good way to fix it in place. So, after discussions with Rick, I shall now proceed to set up a slush fund to buy a brightscreen from him... Not too hard to do with PBJ sandwiches and water for a month! LOL.... I just put the old ground glass back in (minus a stupid spring I lost in the process) and will go shoot a few rolls. The camera really does have a nice lens and if it warms up I will see just how nice after too long a sabbatical.

While you are saving up, I'd recommend buying a new mirror on eBay. It has made a significant difference even in cameras that seemed to have a fine mirror. Less hazy view, better contrast and brighter.

Yeah, good point...and a new spring! Thanks!

...just finished a roll of HP5... that was fun!

TriX next and then I will get my chemicals out, check the dates and refresh next week. I am motivated to develop some film after our redneck "blizzard" in these parts (3" snow) shut down everything for two days, LOL..... I have cabin fever!

That's the vendor I have used for my mirrors. He's very good with communication so you can make sure he knows what the mirror is going into, he might have the exact shape.

One question, how does one actually remove the existing mirror? I forgot to look at that with the WLF off!

I used this site, everything not covered is pretty self-explanatory.

http://pheugo.com/cameras/index.php?page=ciroflex

The one I worked on (for my friend) needed internal viewing lens cleaning as well as removing the funky haze that had built up on the exterior of the rear element. I did the lens cleaning first, checked the view and it made quite a large difference.

It also needed the shutter cleaned (ran slow and stuck at slow speeds), the taking lens cleaned, the focus cam de-greased and re-lubed, the winding knob cleaned and re-greased. Basically everything that site said it might need, it needed.

Nice cam after the work, if I was just starting in TLRs and wasn't sure if I'd like it, I'd definitely seek one out. So simple and straightforward.

Maybe I am missing it... is the mirror glued or screwed down somehow?
