    Hi

    I have a carl zeiss T* lens for my hasselblad 500c/m body I recently bought a 56mm extension tube. On first use the lens locked to the extension no problem and the extension to the body, But once I tried to replace just the lens to the body it would not lock it to place but the extension will still lock to the body If anyone has any idea what may be the problem I would be very greatful to know.


    Thank You

    Nitter.............

    Do you know about making sure the lens and body are cocked? Cock the body by advancing the shutter. Cock the lens by inserting a coin into the small slot on the base of the lens (the part that sits flush with the body) and turning it clockwise until the slot points to the red index dot.

    Other than this I don't know what could be the problem.

    Hi

    Thank you for your very quick response and thank you for fixing my problem. How easy would it have been if this was in the manual :D

    It's in my Hassy manual (covering 500c/m, 500el/m, and swc/m) on page 11.

    I just got my Hassy, so I'm freshly read up on the manual :D

    I've been using other medium format cameras for years, but there are some important do and don't specific to Hassy's and attaching lenses or film backs. Apparently not following some of these procedures can result in the lens or film back locking on the body in a semi-permanent manner (meaning you need to send it off to be fixed), so watch out!

    What's different about the way Hasselblad lenses attach then? I've only ever know bayonets and screws.


    I could be showing myself up here. :oops:

    It's a bayonet mount, but Hassy 500 series cameras use leaf shutters which are in the lens itself, rather than focal plane shutters, which are in the camera body. But the Hassy leaf shutter lenses are normally cocked by turning the crank on the body.

    The body and the lens and the film back all need to be cocked (or all uncocked) when attached so that everything is lined up accordingly, and functions correctly (when you turn the crank the shutter cocks and the film advances).

    Thanks Matt. That's an odd system. I wonder why they used that. :)

    Leaf shutters are almost always in the lens. They don't have the upper range of shutter speeds (above 1/500th or 1/1000th) that focal plane shutters have, but they open all the way on every exposure. That means flash sync at any shutter speed; makes fill flash very easy. They also create a little less camera shake, although the Hassy has the standard SLR mirror movement, which probably makes up for that.

    Having interchangable film backs means not only can you switch film types (BW to color, or a different speed) in mid-roll, but even different fomats (you can go from 6x6 to 6x4.5, digital back, polaroid back, etc...).

    Most of my cameras that use leaf shutters have all the shutter controls on the lens, and advancing the film would be somewhere else, but Hassy wanted to make it so that just one operation (turning the body crank) cocks the shutter and advances the film. There are little indicators on the body, lens, and film back which show what state each part is in; the rule is to never attach anything unless the indicators match.
