Kiev 60 light leak...

[hitmanh]

Ok, I have a Kiev 60 with arsat 80mm that has an inconsistant light leak, example here

Anyone know what could be causing this? Doesn't happen all the time, for example 4 shots on a role of 12 had the leak.

Cheers

Got more examples? Hard to tell from that one sample. There could be many places where light could breach in a K-60. Among these would be in the door seals (as in about just any camera Arsenal made), through the focus screen, or even the little keys at the bottom of the camera.

it might be internal reflections - is the inner part flocked?

 

[hitmanh]

That's the image with the strongest leak. It isn't flocked, so it could internal reflections. That would explain why I only see it in certain shots... either way, I think I'll check out all the seals, and see about getting a flocking kit.

The Arsat has a light leak - a design flaw, through the DOF preview lever on the lens:

Btw, plug the hole on the side of the 80mm Arsat's depth of field lever. You've got one on the camera, so no need for it on the lens. There is a huge light leak thru that hole that can disappoint your first medium format experience.

Put a piece of electrical tape over it and you should be good to go. Do flock the camera though. There used to be sellers who sold Kiev 60 flocking kits on eBay. Pretty easy, use tweasers.

Here's an internal flocking kit:

Thanks Nick 😀

Matt,
I had a similar inconsistent leak with my Kiev 60 and traced it to the DOF lever on the Arsat lens. Instead of simply taping around the lever, I decided to remove it and then tape over the empty cut out. Went fairly well, except that I lost the tiny ball bearing(s?) that provide the click stops for the aperture ring. The lens still works fine but I have to be very conscious of where the aperture is set.:bang:
Arax also sell the flocking kits directly from their web site:http://www.araxphoto.com/accessories/fk-60/
Gevorg is a great person to deal with!

It also could be the shutter curtain, cracked-open ever so slightly, which light streaks the film when you wind the shutter. More noticable in bright light, or if you wind without a lens on.

You can check your K60 for this (it's the classic K60 Shutter-Slit problem) by opening the back, removing the lens, hold it up to bright light, and wind the shutter. You can easily see the problem. You can put "paper blinders" in the shutter curtain area, made from black paper, which will solve this problem. Or, wind the shutter with a lens cap on, otherwise eliminating light through the lens, etc.

OK, I'll check that out once I'ved finished the current film, plus taping over the DOF preview button on the arsat. Hopefully it's one or the other... supposedly the camera was serviced a couple of years ago, so I'm hoping it's not the shuttter curtains...

Zombie Thread Revival!


Re-animating this long dead thread to see if anyone has a description of how to mitigate the shutter gap winding problem on a Kiev 6C.


The statement, "You can put "paper blinders" in the shutter curtain area, made from black paper, which will solve this problem" is interesting, but I cannot find any reference online as to how this is actually done without obscuring the film aperture.


Of course, I can cap the lens while winding, but I'd rather have a more practical solution if possible.


Thanks!


(BTW, Kiev bashers, don't bother. I LIKE tractors and I like my FSU cameras!)

Some general information here.

If the shutter speeds are otherwise OK but capping is inadequate the best solution is to cut new curtains to a size that achieves sufficient overlap between the laths.

You could also try substituting laths that are very slightly wider than original. If you split the difference in size increase between the two exposure shouldn't change too much. Obviously you'll need to fabricate some laths yourself. In theory this should work because your problem is a clearance one (too much). But really the right solution is to install new curtains and, if needed, new ribbons as well.

Thanks, Brett!


Capping the shutter it shall be! 😉

Well if you go down that path, remove the original laths carefully, in case you need to re-use them. Keep any deviations from standard to the minimum, too, because internal clearances and running distances should not be taken for granted. And check your private messages.
