Greetings all - I have been quiet for a while, and am about to share info with some friends.

When shooting a focus stack is it better to move the camera closer - like on a rail, or is it better to move the point of focus while keeping camera in the same place ? Please advise pro's and cons !

Many thanks

Joy

The answer can be either, and there are other options, depending on circumstances. See discussion at https://zerenesystems.com/cms/stacker/docs/troubleshooting/ringversusrail .

I've done both (DSLR Controller and Wemacro) and I find the rail far more versatile.

I have a variety of optical options, some of which require specific solutions.

While focus shifting works quite well with my Tokina 100mm macro lens, it's impossible with my reversed 50mm Minolta manual lens on manual tubes and my 4x and 10x Amscope objectives on a bellows.

DSLR Controller only works with lenses that have:

  1. autofocus
  2. communications with the camera


The Wemacro works with any of my lenses and objectives.
