M7 Shutter Speed Dial Intermediate Settings

Hi All,

I have read from the M7 instruction manual that intermediate speed settings can not be used, but I have sometimes accidently put the shutter speed dial of my M7 on intermediate speed settings (inbetween detents), and was still able to release the shutter. I was wondering since its a electronically controlled shutter, if the actual shutter speed would reflect that (eg, for a itermediate setting between 1/30 and 1/50, would it be something like 1/45, or rather would it be either 1/30 or 1/50).

 

I got used to the soft rotating action of the M8, and occasionally put the M7 shutter speed dial in between detents when shooting in a hurry, its no big deal to the final image, as half a stop is tolerable with film negative. But would it damage any of the shutter dial or shutter release mechanisms? I know its ok with mechanical M.

 

Thanks in Advance

I would say that it is either 1/30 or 1/50 depending on which ever is closer. It is noticeable if you try in between 1 second and 1/2 second.

I don't think it does any harm to the shutter release mechanism.

Quoting the M7 manual (English), page 75, "Intermediate speeds cannot be used.", which I take to mean that one speed on either side of the intermediate is used, and I agree with Dick that no harm is done. I've done it many times.

I just wish it had M8's shutter speed dials, where you can set half stops.

 

:)

 

It is not as comfortable as with the M8, but if need be, with the M7 you can compensate the EV at 1/3 EV intervals in the range of +/- 2EV with the exposure compensation dial (even more accurate than half stops :)). The only problem is that you will have to reset it deliberately if you want to deactivate it.

If the jinn of the lamp did this then you would have to send your M back to Solms when the shutter had a fault, perhaps you have to do that with a M7 anyway?

 

The Barnack shutter is simple such that any repair person should be able to repair it with hand tools.

 

Unless you have a Hologon (or similar) you can use the lens aperture....

Good point. Its just using the exposure compensation is a bit slow.
