Questions on a bellows photographic setup.

Post by Microman2 »

I would like to emulate the photographic system of Charles Krebs as seen from the link: http://www.krebsmicro.com/microsetup2/index.html. However, I have some confusion with regards to how a bellow works. Does the front standard of the bellow have any lens elements? In Kreb's photograph, it seems that a camera lens is attached to the rear end of the bellow, with the front end having no optical parts and only used for parfocality adjustment.

There are no lenses at all. The projection eyepiece projects the image directly to the sensor. The bellows are only there to block out ambient light. In use, the front stand of the bellows is lowered down so as to cover the projection eyepiece.

The rear end of the bellows has a lensless adapter. It is only there to allow attaching the Vivitar bellows to Charle's Canon camera body. No optics.

I have essentially the same setup as Charles Krebs (same scope, different camera). But, instead of using a bellows I use a tube of black paper - works great.

Likely placing a good multicoated filter will be useful for protecting the sensor from dust
