I love these videos.I've been starting to do some basic repair work on some of my old cameras,and the information in these is very useful.Most of it I haven't seen anywhere else,so thanks for filming these.I always watch for new ones to watch.
"It is an element of this discovery, regardless of economics, to maintain and use these elegantly engineered cameras of the 60's, 70’s, and 80’s, that is intrinsically rewarding in and of itself." from miketrost.com
One of best channel on TH-cam. Thanks.
Thank you for this video from Spain .
I just received some great old film cameras and am so glad I found this. It absolutely confirmed I'll send those cameras out to be CLA'd lol. There is no way I could do this without turning a cleaning into a major repair lol.
It is not for everybody, but at some point with some camera give one of the repairs shown a try. With patience and persistence you will keep'em going.
Fix Old Cameras I actually shocked myself. After saying that but watching more of your vids I was able to clean dust off the prism and viewfinder of my Minolta srt 201 and 202. Thanks so much for the great details and inspiration
Fix Old Cameras and your diy spanner is genius. I've made a set for all my film cameras. Brilliant.
Good to hear it is of some help.
Right on. Keep'em going.
Die Begeisterung ist ja imens.
Da bekommt man gleich " richtig gute Laune".
I can confirm this is the similar if not same method used to replace or clean the OM-20/G. I'm half way done replacing mine. Be careful removing the plastic clip as it has two holes to which it goes back into.
Thank you for your comments and insight.
Thank you so much this clips...I need to open the focusing screen of OM 40.. This is so useful to clean my camera.
You are welcome.

Thank you so much for all the wonderful videos!!
I feel very fortunate for finding this channel :)
Could you please do a viewfinder cleaning video for the Pentax K1000 ?
I'd really appreciate the help
Thanks again!!
Thank you for your suggestion and interest in Fix Old Cameras. A Fix Old Camera video on cleaning the viewfinder of the Pentax K-1000 will be posted soon.
Thank you so much for the video!
I have a question on what is the best way to clean the mirror, when I touched it or when small drops of something fell on to it. Not dust. Blower won't help. Some say that it is better to leave it the way it is, an do not even touch it even with microfiber swab and special liquid for sensors. Some say you may clean it carefully with microfiber alone. Camera is Pentax K1000. Thank you very much for the comment.
The mirror can be gently cleaned as you would a lens. The viewfinder screen CAN NOT be cleaned with any cleaner except distilled water. Try dabbing at the specs with a lint free cleaning swab moistened with distilled water. You can also follow the concentric rings of the VF fresnel lens with the distilled water cleaning swab. Then dry with a blast of filtered air.
@@FixOldCameras Thanks!
Great video, but I don't think I am confident enough to do it so I think I will be sending it to Liverpool. Better safe than sorry and I like this little camera when it has the manual override on, it's my grab and go camera Fujifilm Superior 400 in. So I think I'll play rather safe than sorry as my other cameras seem to have specific niche.
Thank you for your comments and interest in FOC.
Simple and precise. Thank you for sharing!
Thank you for your interest in FOC
Another great vid. keep em coming. can't wait for the Canon QL17 to come.......
Thanks for your interest and patience. The QL17 is a great camera.
OK in regards to my comments about Olympus OM10 camera shutter speed indicator LED's not working..fixed it and the fix was easy: I have a spray can of 'electronic circuit cleaner'. Very carefully sprayed a bit around the shutter button and the collar around it (which is a pressure-sensitive switch), the ASA/mode selection dial, and the on/off/battery check/self timer switch. After working these parts a bit with a couple judicious applications of the cleaner material: problem solved. Shutter speeds now properly displayed by the LED indicators along the left hand side of the viewfinder. I suspected that a contact point had some hidden gunk buildup or corrosion and the liquid material I used took care of it. So now my $35.00 antique shop find SLR is working just fine.
Good to hear of your successful repair and thank you for your comments.
Great videos!
I have an OM10, but without the glued on cover plate. Can the absence of the cover cause any disadvantage (light leak, function problems), or is it just for the aesthetics? Thank you for the answer!
Hello, can you do a video on how to clean the viewfinder & prism on the Nikon FM2?
I made a newbie mistake and cleaned my viewfinder with alcohol leaving black streaks on the viewfinder. Does anyone know how to fix this? Or do I need to get it replaced now?
Hi,
Very helpful video. I struggle with which side of the viewfinder glass goes to the top mirror? The matt or the glossy side.
i found cleaning the screen in an ultrasound bath with demin water to work very well
That is a good way to proceed with the fragile Fresnel lens of the VF screen. However, demineralised water and an ultrasonic cleaner are not as readily available as the distilled water and cleaning swab. Thank you for your comments.
Thank you for the very informative video. My OM10 was transported and the viewfinder screen was completely out of its place. I pushed it back and it only hooked on the upper side so I should do the exact same procedure. My question is, how bad it is if the viewfinder screen is scratched?
It is only annoying, not bad at all.
@@FixOldCameras thank you so much for replying. Will report with the result :).
Would the procedure be similar for a Minolta XGM?
how would you go about a deeper clean if there is a smudge on the focussing screen?
You can take a microfiber cloth lightly dampened with water, wrap the focusing screen in it and wipe gently. If you do this very carefully, you can wipe off the stains without damaging the screen. What kind of spot do you have on the focusing screen?
What if you made the mistake of attempting to clean the focus glass with alcohol? Pentax K1000
CANON AV1 Viewfinder Cleaning Video ?
thank you for this video👌
Glad to hear of your interest in FOC.
Can you guys do this on a Minolta xg1? Mine seems to be a bit more different than what is shown
Why rest the screen on the mirror? It will scratch.
Take it out with some padded tweezers, and you’ll also be able to get a look at the underside of the prism.
The less the fragile screen can be handle the better, however padded tweezers should be safe.
Hi, would the procedure be the same for a Minolta X-700?
Congratulations for your TH-cam work. These videos are very instructive.
I have two questions: is the Pentax ME viewfinder screen removable like the OM-10's? What kind of glue is the one you use? don't know that brand in Portugal. thank you.
Unfortunately the finder screen in the Pentax ME is fixed. You need to remove the top cover, upper circuits and prism to access the the screen. If you can not get the particular brand, a permanent office glue stick will work on pliable leatherette, on stiff leatherette double sided carpet tape can be used. Contact cements can be used also, but sometimes can be difficult to remove should you need to service the camera again. If you have a specific classic camera gluing issue, other than the attachment of leatherette, than other options can be explored.
Thank you! Best regards.
Could you explain type of glue?
Can anything be done about the shutter speed indicator LED not operating? Shutter on my OM10 seems to be working fine just the camera-selected shutter speed is not indicated along the shutter-speed column on the left hand side of the viewfinder. My OM10 was an antique-shop find everything else on the camera is working fine except no shutter speed indication. Shutter seems to be working properly as it changes speed according to lighting and lens aperture selection.
This might seem obvious and it is doubtful you overlooked it... but make sure the on/off switch is on. The OM-10 (and the OM-G) will release in the "off" mode but the LED only illuminate when the camera is turned to the "on" mode.
Thanks for the video. Is it necessary to add back the foam strip at the end of the repair procedure?
It is not absolutely necessary to replace the foam mirror cushion, but would be preferred.

Great video! Is the procedure the same with a Canon AE-1?
Thank you, but unfortunately the Canon AE-1 has a sealed prism and Viewfinder screen.
I'm assuming the ompc is the same way? I have to change to a 1-7 prizm so I can use my 600mm f6.5 and my 1000mm f11.
It is not, assuming that all manufacturing runs of the OMPC and OM-40 are the same ... the prism will need to be removed to access the viewfinder screen.
however after replacement the focusing is way off. if i focus on an object 10 feet away, my distance scale on the lens says 5. found this problem in other om10 as well after precious owner did the replacement. i wonder what i did wrong...
Sounds like the VF screen might have flipped or is not seated properly.
I have a zent ttl camera , I'm having a hard time opening the film. Help me out, if possible, please .
I recently got an OM-10, and it seems like the mirror isn't sitting in the right position, because with all my OM-mount lenses, it can't bring distant subjects into focus in the viewfinder (i.e. won't infinity focus). This despite those same lenses appearing to focus correctly in my OM-4's viewfinder. Another thing that makes me think the mirror isn't sitting right is that even when I'm able to align the split image in the finder, everything still looks a little blurry. The camera has a good set of batteries in it, and seems to function properly in all other ways. Any idea what the problem might be and whether it's a possible home repair?
It would be unusual but not impossible for the mirror not to seat properly, yet till allow the camera to operate. It seems more likely that possible the focus screen might be flipped or improperly seated.
@@FixOldCameras Hmm, ok, I'll try flipping the focusing screen. Thanks for your videos, and for your reply!
Is it really needed to glue the ceramic cover plate back? I am a bit wary on glueing it. Also is there any other glue I could use ?
+Prop Eaters The felt seals that run along the side might retain enough adhesion to hold the plate in place. Give it a try. However, Pliobond has proven itself as a very good multipurpose adhesive with 36 years of personal application in the repair of cameras. It does have a tendency to leave strings of glue as you pull away the applicator, but with a little practice they can be managed easily. Although, there are likely some good substitutes available.
There’s a smudge of the mirror foam on the plate and I can’t get it out will it show up on photos later?
It will not as the prism, focus screen and mirror are for viewing only.
Thank you for your guide, but it seems difficult and I have not enough guts to try :D
You interest in Fix Old Cameras is appreciated. Maybe in the future you will come across a camera that you can try a repair on.
The best thing to do is buy a Junk camera for a few $ and try with that first
any idea how to remove the screen on a canon av-1?
I was prying the cover off and the glue released all at once and my piece flew across my room, i spent two hours moving, sweeping and sifting through stuff.
Grrr... that is frustrating. Nearly all who might attempt to repair a camera will end up crawling around searching for a roll away bearing or screw or chasing a spring flying off into parts unknown.
@@FixOldCameras I did find it, now i just need to buy some foam sealers from the mirror and back of the camera.
I thought the manuals for the type of cameras with replaceable viewfinder-screens warned that it had to be put in very specifically to be in focus or something like that. - Is that just a lie or excuse so that people would send them to a service-center to catch more money?...
The viewfinder screens need to be handle carefully as the scratch very easily. There are specialty tweezers that are made specifically for changing out viewfinder screens, but if care is used the demonstrated method should be in the doable my most people with a little patience and skill.
I mistakenly wiped my OM10 viewfinder screen with alcohol. It seems it becomes grainy when I look at the view finder. Did I ruined it?
Yes. Alcohol fogs the plastic of the Fresnel lens of the view screen. Only clean with distilled water.
@@FixOldCameras are viewfinders for each camera different or is there a standard size that i can get anywhere. i did this same thing on my pentax k1000 viewfinder and cannot find a new one for sale anywhere. thank you
i just don’t want to have to get rid of the whole camera because it’s fully functional but i can’t see what i’m looking at when using it
hello! please help! my view finder is dirty... with that black thing... how can I fix it?
If the mirror cushion foam has smudged the screen use a cleaning swab saturated with distilled water and follow the concentric rings of the VF screen. DO NOT use lens cleaner or alcohol on the VF screen. The bad news is the degraded foam will often leave scarring even after it has been removed from the screen.
My view finder screen has a stain from the cushion. What do I do? It’s a canon ae 1
The mirror can be gently cleaned as you would a lens. The viewfinder screen CAN NOT be cleaned with any cleaner except distilled water. Try dabbing at the specs with a lint free cleaning swab moistened with distilled water. If it is smudged, you can also follow the concentric rings of the VF fresnel lens with the distilled water saturated cleaning swab. Then dry with a blast of filtered air.
I did that but I still have a spot on my viewfinder from the outside (the square where I look to take a picture) I can’t get rid of it any idea how to fix that?
Depends on what and where the spot is. Check the surface of the prism along with both sides of the focus screen. If you are seeing it in the viewfinder it will be there or you have separation of the reflective coating of the prism, in that case the prism will usually need to be replaced.
Hi i recently purchased a L viewfinder to replace the standard viewfinder for a Minolta 7000. Is the procedure of the OM-10 similar for the Minolta camera. Thanks.....
The VF screen retaining clip release for the Minolta Maxxum 7000 is located in approximately the same position as the screw that holds the VF clip of the OM-10
Thank you for you're reply. keep up the great work you do.....you're video's are so helpful....
how can i find a new one for my om-20 the one i have on my machine have big scratches and i want to change it.
Probably need a donor camera.
@@FixOldCameras i cannot be sure if the donor camera have a clean one, i cant go outside i only can find a donor camera from internet. I wish they could only sell that part.
Good video! How is this process in the Praktica BCA? Do I need to remove the top cover? Thanks
Confirmation of the following is presently not absolute. However, the top cover and then the prism probably will need to be removed to access the VF screen.
To remove the cover do I need to remove individually the components like the mode selector, winder, ASA indicator, ... or I just unscrew the top screws and lift? Thanks!
The shutter speed dial, assc. shoe, and shutter release button will not be removed, they remain in place for top cover removal. Only the rewind knob, the on/of switch plate c-ring retainer, on/off switch plate itself (check the switch plate as the spring detent is prone to failure) and the advance lever and related parts will need to be removed.
Thanks, will try. Sometimes it seems the electronics fail (shutter speed led only lights up for a second) and the shutter sticks for several seconds or until it's cocked again. What do you think it is?
What is described in the previous FOC post applies to the OM-10... not the Praktica BCA. Forgot you were asking about the BCA not the OM-10 featured in the video. The BCA advance lever has a plastic cover that is held in place with screws that are on the underside of the lever.
Can u show how to clean for Fg20????
Thank your for the suggestion and for your interest in FOC.
hi, I wanna know how to remove the focusing screen on my Canon AE1, because it has dirt inside, I try to clean it from outside, so I think the dirt is on the opposite side
The Canon AE-1 has a sealed focus screen and prism, but as you have found out dust can still invade the space between the prism and the screen. It is a considerable task as the top cover, upper circuitry and prism need to be removed to access the inner surfaces of the screen assembly.
Can you make one for a canon FT
Thank you for your interest in FOC. The Canon FT screen is accessed by removing the top cover and prism and could at some point in time be featured specifically. This video of the Canon FTb might be helpful. th-cam.com/video/yzgVodBm-DY/w-d-xo.html
is it the same way to go with the Canon ftb?
The Canon ftb VF screen will need to be accessed by removing the top cover and prism.
@@FixOldCameras sounds complicated :(
Same as the OM-G?
Very similar.
the most boring voice tone :(
Thank you for taking the time to watch and comment on a FOC video. Fortunately a high energy speaking style is not needed for camera repair. However now, in addition to its original intention as a video guide to a simple repair procedure, it might be possible from your opinion of the somniferous nature of the narration of this video, some viewers could also find this particular video useful as a inducement for a quick nap.
