Kodak Monitor 620

Sorry, posted wrong subject.

 

Hi -

I recently acquired a Kodak Monitor 620 with a Kodak Anastigmat 103mm F:4.5

lens and a Kodak Kodamatic NO. 1 shutter with speeds of B, 10, 25, 50, 100,

200.

 

I had it recently overhauled and to my suprise was less than satisfied with its

results on a Fuji Superia 100, 120 film. The results lacked sharpness and

contrast even when the lens was closed at f11 and the shutter speed was set

1/200s.

 

I am concerned about two things: 1) Film flatness, 2) Steadying the camera on a

tripod.

 

On the 1st concern, has anyone had a problem with film flatness on this unit?

The film set up is as scuh: regular 120 roll with clipped lips in order to fit,

and a 620 take up spool, which seems to work well as far as advancing, and

frame count.

 

On a second concern, this camera has not tripod socket? How do you mount it on

a tripod?

 

Thank you in advance.

The lens of my Monitor Six-16 (an Anastigmat Special) is tack sharp. Maybe your lens is not correctly collimated. Here are two ways how to control the front ring's position at "infinity": <br>

The lens not properly adjusted may be a possibility, although my camera reapir man indicated that that was adjusted as well.

Is it possible to adjust the pressure plate maybe?

First I'd control the lens adjustment by following these steps:<p> Get a spare film and cut a small window into the black paper so that light from the camera's red window can pass to the film whose emulsion side you should criss-cross with fine lines ( by using a needle or a razor blade). <p>Put the film in the camera so that this area is within the frame, close the camera and shine light of a desk lamp through the red window. Set the Monitor lens for "infinity".

 

By taking a SLR with a long lens (or binoculars) that has also been focused for "infinity" - and by looking directly into the Monitor lens - you should see the scratches on the film in every detail, if your camera is properly collimated. If you resolution improves with the focusing ring being at another position, the ring has to be re-adjusted by cautiously loosing the tiny screws and turning the ring accordingly. <p>

 

 

I apologize for this clumsy description of a makeshift autocollimation set-up. But if I used my mother tongue it might be even less understandable . </p>

A piece of wax paper cut like film and loaded like it was film will give you an image you can focus on. See if a target 5 ft is in agreement with the 5 ft marked on the lens then check if infinity is in focus. That will tell you a lot. Note 5ft was just a guess try whatever is marked clearly on your lens focus ring.

Scotch® Magic® tape makes a pretty handy ground glass.

 

To correct the collimation (if that is what's off), there are three very small set-screws around the outside of the focusing scale. Loosen them, and it will turn relative to the front lens element.

 

Another possibility is that the middle element (what the focusing one screws into) isn't properly tightened, or the rear element is loose.

 

I presume that all the glass is clean.

 

As for the tripod sockets, they are covered by little chromed steel plugs with a coin slot in the head. One on the door/bed, one on the side opposite the knobs/viewfinder. Use a dime or penny, and don't lose them.

 

Nice cameras, I've got one with the Anastigmat Special lens. You're lucky to have one with a good bellows. I had to replace the bellows on both my Monitor Six-20 and Six-16.

Whern I got it the elements had haze inside, but are sparkling clean right now as my repair man cleaned them. He also adjusted focusing as well, I guess I can ask him to check focusing again.

Hi Again Ralf,

 

Hope all's well with your Monitor 620's lens! I just thought of something that you may already know...but here 'goes anyway! If your camera is like mine (which has the Anastigmat Special lens), it also has a built-in mechanism/procedure for implementing automatic film stops. This allows you to cover the film-number window with electrical tape and get 16 6x9 images on a roll of 220 film.

 

If you're not familiar with the procedure, I'll describe it in a post tomorrow!
