  1. I have an Aires IIIA (c. 1956) with a Seikosha MXL shutter.

     

    One of the aperture blades seems to be stuck in the open position. When

    decreasing the shutter opening setting from max (f/2.8), there appears an open

    off-center slot that gets narrower and narrower with increasing f/stop.

    Should this clear up with cleaning or expercise (exercise hasn't worked yet)

    or is it more likely that the blade attachment to the shutter mechanism needs

    repair? The shutter operation speeds seems to be ok at all speeds.

     

    Thanks,

  2. This subject has probably been beat to death before, but ...

    I am trying to remove the top of a Japanese camera (ME Super Spotmatic) and

    got down to the last screw (of course) and cannot budge it. It is a 1.6 mm

    screw with a head of about 2 mm diameter. I have searched here and elsewhere

    and have made sure to get and use a cross-point driver (rather than a

    Phillips), tried penetrating oil, acetone, and lighter fluid. I then tried

    heating the head with a soldering iron. Nothing has worked. In the process,

    of course, I have boogered up the slot some, although the cross-point driver

    will still engage. Is there an "easy-out" this small? The head is elongated,

    so there would theoretically be room to get a few threadeds of a left-handed

    easy-out or similar tool engaged. I don't want to drill out the entire screw -

    especially since the head is still there. Any ideas?? Thanks, Larry

  3. I picked up a Cosina 80-200mm lens (f/4.5-5.6, MC Macro), but I can't match

    the bayonet mount. Were these lenses manufactured in numerous mounts? How

    would I go about identifying the mount - i.e. what camera(s)it fits -

    unfortunately none I have (not Pentax ME Super, Nikon FG, Ricoh KR-30sp

    Program, or Canon AE-1 Program).

     

    The lens has the typical three bayonet flanges of increasing widths. These

    are about 15mm, 18mm and 20mm in width.

     

    If it means anything to any of you, the lens S/N is OM92413117.

     

    Thanks in advance. You folks never let me down.<div>00IjV9-33419184.thumb.JPG.dcdfe453f50a09db8ad3dbe8908eea3a.JPG</div>

  4. I just picked up a Contaflex I SLR, but I'm not sure the shutter is working.

    When I wind the film advance, the diaphragm opens and the mirror drops into

    place and I can see through the viewfinder fine. But when I press the release

    the diaphragm closes and the mirror pops up, but the shutter does not seem to

    work - like it wasn't cocked in the winding. If I take the back off and press

    the release, I see no light through the lens - at any speed. Then I got to

    thinking, does this camera require film to be loaded to cock the shutter -

    like a Voigtlander Vito B?

     

    I haven't been able to find a (free) manual online, so if anyone knows where,

    I'd appreciate it.

  5. Let me add my own question in this discussion. What about when the cameas are on display? Also my display cabinet (newly moved) receives a few minutes of direct evening sun. Should the apertures be open wide or small, or am I just asking for trouble?
  6. These Minoltas were famous, apparently, for poor soldering. It may well be that a bad solder joint came loose. This situation was made worse by the PZ640 murcury batteries if left in the camera for long periods - electrical contacts, especially near the battery, became corroded. I have a Hi-Matic E that suffered this. The corrosion, if it hasn't broken the electrical connection, is very brittle, so yours could have come loose in your use of the camera. I don't know about the F, but the bottom of the E comes off easily with two screws, and you can check out the main battery wires. On mine, the black wire was heavily corroded and the red was not.
  7. I just got my Instamatic Reflex running using a substitute battery and some nickels. The Reflex required 2 of the big murcury PX825 1.5V batteries. They mount in the little tray that pulls out of the bottom of the camera. Get a lithium CR2032 battery which is 3V. Place the 2032 in the front position in the battery tray (by front I mean the portion that inserts into the battery compartment first). Place 2 nickels on top of the 2032 and put 3 nickels in the rear position. Works fine.

  8. Rose, I also have both of thes nice cameras - my only two Zeiss Ikons. Actually I have Two Contina IIa's - one needs a new front element for the Novicar lens. So if anyone has one, let me know.

     

    I just picked up my Contaflex I. If I ran a roll through it, the film would be blank, too. I can wind and fire but that seems to only raise the mirror. If I take the back off and hold the camera up to light, when the release is pressed, no light is seen coming through the lens. My mirror is also quite dirty, but you can't get at the mirror in a normal SLR fashion as the lens isn't removable. The only thing that seems wrong with the adjustmenst is that the MXV lever only moves between the V (self timer) and sort of to the X setting, although it feels like it never really engages the X position. Don't know if that has anything to do with the leaf shutter not working. Oh, also the aperture ring only adjusts down to about f/8, even though the ring rotates further.

     

    Any help would be appreciated.

  9. I have a Nikon N8008s and an SB-26 Speedlight. I want to take some

    shots with the flash off-camera, the N8008s doesn't have a flash

    cord port - one has to buy a special $50 hot shoe cord. So I was

    wondering if I can use my old Pentax Spotmatic with the SB-26 in

    manual using a standard PC cord, attaching to the PC port on the SB-

    26 (?). Thanks.

  10. I couldn't resist posting this one. This was the first of my own photos that came to mind on reading about this upcoming contest, which I think is a fun idea. I personally like the idea of shots taken with a 50's camera of something from or about the 50's. Since this shot was of the 50's but not by a 50's camera, I couldn't enter it, anyway. But any guy that was at least 6 years old in the 50's knows what this is and remembers when they were new.<div>00BhS3-22638984.jpg.f9d111a453776a8dd31220f0b9194355.jpg</div>
