academic question

ceriltheblade · 29th of July 2012 (Sun)

i was reading a different forum and someone mentioned that some people in macro use an "auxiallry leaf shutter" to reduce vibrations from the mechanical shutter of the camera
and all i could understand from google - was that it is some sort of shutter that is associated with the lens instead of the body.

can someone explain this better to me?
is it something that people use in modern crop/35mm DSLR cameras?
thanks for any help...

Not heard of anyone using it with a normal DSLR setup.
It might be something that is used with very high mag setups (ie 10:1 or higher) with microscope lenses.

Back in the old film days, Hasselblad F-series cameras had focal plane shutters but when used with a CF lens one could choose to use the leaf shutter built into the lens if one wished.

The main reason to do so was for flash sync up to 1/500th...I can't imagine any blur due to vibration being caused by the focal plane shutter on a modern DSLR, but as LordV says, with extreme magnification, I suppose it is possible.

Leaf shutters are found in medium and large format cameras. There are slr's with a leaf shutter but they are medium format slr's. It is a shutter that exists between the 2 lens elements inside of a bellows seen on old cameras like view's and as rrblint said hassleblad but there are also a few others. The large format cameras are capable of shooting a max shutter speed of 1/500. For macro work, from what I have gathered, large and medium formats can be equipped with an external leaf shutter which is similar to using mirror lockup on a regular DSLR.

thanks all for the information. I had never heard of such a device - but it makes sense because I know absolutely nothing about medium or large format cameras....
heck, i just started this hobby about 3 years ago on a low level...

thanks for the information. I read as much as i can, and I tried google, but nothing i could really understand came up (i guess i didn't ask the right questions)
