exposure and aperture

[ian_humphrey]

<p>Hasselblad 500c/m. Is it possible to set 1/2 stops in either f stop or shutter speed with this camera. It seems a bit fiddly and there is a very faint click at 1/2 way between settings and not sure if this is ok.<br>

many thanks<br>

Ian.</p>

Not the shutter, but the aperture yes

[dave_wilson1]

Which lens series Btw?

[ian_humphrey]

<p>Hi Dave<br>

The lens is a f=80mm Carl Zeiss lens planar t* 1:2,8 Nr 62732681.<br>

Hope you can enlighten me.<br>

Many thanks<br>

<i>"Hope you can enlighten me."</i><br><br>Dave already has with his first reply. ;-)<br>Only the aperture goes in half stops. So always set the two so that the shutterspeeds 'click in'.

<p>The click stop on apertures is usually a small steel ball with spring pressure pushing it into a grove that is about 1/3 the ball diameter deep. On some shutters it is a half ball made onto a spring steel finger fitting into a shallow grove. If the click stops are weak it suggest the lubrication for the ball has dried and it is sticking in the spring cylinder, the groves are worn, or both. Nothing to worry about either way and not worth the expense of disassembling the lens unless you want solid click stops.</p>

Hi Ian, just acknowledging you back, everything is all covered. The only thing to consider is that if the lens is hard to

operate properly, a good tech such as David Odess, who has a great rep, but I've never dealt with personally, or Brad

Sherman in NJ who I have, if he's still repairing can settle things up for you.

<p>The shutter dial should operate smoothly from one end of the scale to the other, with about the same resistance as the aperture dial. If it is hard to move, especially toward either end, stop using it and send it in for service immediately. In all likelihood, all it needs is cleaning and lubrication. However if you continue to use it, something will break and it will cost you $500 instead of $100, if you can even find parts (e.g., for a C lens).</p>

<p>Thanks for all your responses. The shutter dial and aperture all work smoothly now I have got the hang of it and they click in quite positively. I am not convinced that I can not select 1/2 shutter speeds as well as 1/2 apertures as they do seem to have half way points, but perhaps that is wishful thinking.<br>

Once again<br>

Many thanks<br>

What is it a Compur shutter? I'm not a

shutter expert by any means, but I'm

pretty sure the Hasselblad lens

shutters like yours have cams and only

work at the speeds indicated, but

others wo cams might be able to select

certain intermediate, but not all.

[q.g._de_bakker]

There are no (!) intermediate shutterspeeds.<br>There are no intermediate clickstops in the shutterspeed ring either, only in the aperture ring.<br>If you set the shutterspeed ring in between two speeds, the shutter will 'do' one or the other. Which one remains to be seen.

<p>Thanks QG<br>

It was Dave who provided the answer, in the very first response you got, Ian. ;-)
