How to set up menu in S007 when using CS lens?

Hi everyone,

 

I have a quick question. I just acquired a CS version of the 70 lens. But I do not see any options in the menu of the 007 about setting up this lens for fast sync speed. Can you instruct me how this is done?

many thanks.

Hi,

If you're referring to using the actual CS shutter, there's a "CS" knob that's next to the "Off" and "FPS". Upper left hand corner.

Switch to "CS" and you'll be able to use the central shutter on your 70mm lens. From there, you can adjust your shutter to whatever shutter speed to sync with your lights, up to 1/500 s.

Hope that helps.

Thanks!! Do you mean the switch that switches the camera on?  CS/FPS/OFF?   So If I just switch to the CS mark, it mean the camera will recognize that this lens is a CS version lens? So when I use the lights, it will just allow me to sync up to 1/500s? I do not need to adjust anything in the menu for that? 

 

Best,

You don't need to select anything in the menu. The FPS button means focal plane shutter, the CS means central shutter. Put it on CS and it will use the central shutter for every shot, and in doing so the sync speed will be whatever speed you choose up to the max speed of the central shutter, which I believe is 1/1000th, not 1/500th.

You can also use the focal plane shutter with a CS lens (but not vice versa of course). And it’s still a power switch, so remember to turn it off either way!

Thank you so much for your help. I am curious. If we use CS without the flash, does it mean less camera shake? CS shutter theoretically should involve less vibration, right?

In camera systems without a focal plane shutter, yes, that is often the case. I remember this question being asked of David Farkas at Leica Store Miami, and his response was that it did not affect the amount of vibration. The reason for this is that when you use the central shutter, the focal place shutter still needs to be opened and closed, and the mirror still needs to swing out of the way. So his claim was that the central shutters did not help with vibration in the S cameras...they just allow you a high flash sync speed.

Thanks. So it means that when I am not using the high-speed sync, it does not make sense to use the CS option at all...

Yes.

I would add to that, I have the 70CS which I used far more than anything other lens, for tens of thousands of exposures with S2 and Typ 007 in studio over five years or so.. That was typically in rapid series and high volumes (800 plus frames in half day) for fashion etc in studio.  I was using a bit higher sync speed with CS (1/180) primarily from habit ( to reduce ambient light effect , probably making no difference) that I knew worked with my studio flashes.

In any event, after the AF motor fail (warranty) the central shutter failed (not covered by the AF fail repair warranty) Then some months later that CS failed a second time ( warranty of last repair).

I recommend that you don’t routinely use the CS function if you don’t need it to sync with ambient light on location.
