Flash Photograph with Sekor c 70mm

[leon_yuhanov]

Hi,

I have recently purchased a Mamyia m645 Medium Format Camera with a 70mm Sekor

C Lense. I noticed that the lense has a X terminal for a flash. I am also told

that this camera can snc up to 1/500?? The mnual says it will sync to 1/60 and

slower speeds when using the cameras X terminal but says nothign abotu the

lense.

 

If nayone has a manual for this lense, can you please send it to me? Im happy

to pay for a reprint. Iether way if someone has any idea how to sync the camera

and lense to faster then 1/60th speeds let me know!

 

Thanks

Leon

I believe the 70mm lens for M645 is a leaf shutter lens. M645 is a focal plane system on its own, so lenses without built-in shutters will only sync t 1/60s (most of the lenses for the system). There are some leaf shutter lenses for the system and those sync all the way upto 1/500s (the advantage of leaf shutters). Check <a href = "http://www.mamiya.com">Mamiya's website</a> for manuals for M645. You needs to use IE to access the website.

The lense has its own leaf shutter, what im after is its manual or a sugestion on how to us ethe lenses shutter to sync to a flash!

If the use of leaf shutter lenses is not described in M645 manual, try to search this website for "Mamiya 70mm LS". The shutter leaf lenses for M645 are being discussed once in a while and I remember people posting los of details of how to use the lens.
