Question about Hasselblad 503CX Medium Format Camera

1 Answer

Rear curtain won't close fully

I am looking at purchasing a 503cx and noticed that when the rear curtain folds back after firing sometimes the bottom curtain does not close fully, leaving a tiny gap that does let in a tiny amount of light. This does not occur every time. And the gap this is present is about 3mm. I thought this could be from lack of use as the camera has not been used for about 6 months. Any Advice. Thanks

Re: rear curtain won't close fully

It's a sign the mechanism needs a cleaning and lube. Temporarily you might try releasing the shutter ( without a lens mounted ) and locking the release button down. Then CAREFULLY from the back, put a little upward pressure on the metal curtain 1/4 inch or so, to twist the curtain slightly on it's shaft. Don't pull to far or you can do permanent damage. You should have a repair shop take care of it.

Light leakage detected from my second hand PRO TL especially at low shutter speed (<1/15 sec). Details are as follows: a) appeared at lower third of a frame; b) spread out evenly from 3 points lying...

It sounds like the aux. curtain that covers the film when you're focusing either is not properly lowering, or is damaged somehow. You can remove the back and look through to see if you notice any light coming through. If you do, consult a tech. You'd only notice it on frames because mid-frames wouldn't remain in the light path long enough to be affected under most circumstances. It'd likely be a tear/nick in the curtain. Or, it could just not be completely be closing.

It could also be an issue with bad seals in the film back, or between the back and body, or even a crack somewhere in the back or the body itself. If you can't find a leak in the curtain, try keeping the dark slide in right up til you take a shot in, taking it out as soon as you're ready to shoot, replacing it before you wind, etc. to minimize the amount of time light could come from the anywhere but the back - to try and narrow down the location of the leak.

I have a hasselblad 503cx. when i hit the shutter button, the back part of the lens opens (where the film is) but the lens shutter is closed. when i let go, the lens opens and the back closes.

The proper order of exposure should be:

Curtain opens/Lense stops down (unless wide open)
Lense shutter closes
When releasing button, curtain closes
When winding, lense shutter opens

If this isn't what's happening, something is wrong. There is only a simple mechanical screw connection between body and lense, so it'd have to be an issue with the gears in the body.

The shutter speeds on my Horizon Perfekt do not change when i adjust the dial.

The shutter speed is controlled by the width of the slit exposing the film. So, the lens will swing at the same speed when set at 1/500 or 1/60 (White setting), therefore it appears on the outside that the shutter speed has not changed. The swing has only 2 speeds, White fast, Yellow slow, selected by the switch on the left beside the rewind knob.

To confirm that the width of the slit is changing (actual shutter speed), open the back and fire the shutter on Yellow 2 (half second), you will see the slit is fully open as the lens swings. Next try Yellow 8, you will see the slit is less than half open, so it exposes the film for a shorter time by having a narrower slit , not faster swing.

This is the same principle in many cameras with curtain shutter.

I hope this answers your question.

Can you shoot rear curtain flash modes?

If not, try this:

Advance the camera.
Open up the shutter(set mirror lock-up). You'll have to remove the Winder CW to do this.
Push black Tap up to open up the shutter. Don't worry, lens is still closed.
You'll not see anything from the viewfinder, just black.
Trip the shutter button.
Now, check the images.
What do you get?
Try shooting under one second in low light.
Battery is new and not over 5 years old?

This sounds like the second shutter curtain is not closing completely - it's not reaching the right hand side of the shutter opening; or it's sticking & thus taking a long time to close so the part of the frame behind that area gets massively overexposed. You can check this by firing the shutter with no film in the camera and the back open. If I'm right, I'm afraid it's a repair shop job - unless you can see a hair or something like it caught up in the shutter. If so, you might just be able to remove it (all of it!) with tweezers.

Streaks of light in some of my pictures

There is probably a pinhole in the shutter curtain. Open the back and check for pinholes with a bright light. If there are a small number of holes they can be easily patched. If the curtain is full of holes the curtain will have to be replaced.
