In Topic: Full Frame SLR wide angle corrector port tests

29 December 2014 - 10:22 PM

Just as another data point for those interested in correctors, I have been using Rebikoff manufactured afocal correctors for many years for my 3D stereo work and find them to be an excellent tool. They have allowed me to get relatively wider angle stereo images with normal stereo bases (e.g., 65mm) which would be practically impossible with dual dome ports. Unlike the Carl Zeiss corrector system that Alex describes, the correctors made by Rebikoff are dual optics combined a single lens housing and the taking optic has to be placed within a few millimeters of the corrector's rear optic. Also, my particular units only accept taking lenses with a 35mm or greater focal length (measured in 35mm format). Any wider, and the taking lens sees the inside of the corrector. I understand that the Ivanoff/Rebkoff type correctors can be designed to accommodate wide field of view. Whether the Zeiss correctors are of this type and illustrate the principle is unknown to me.

Hi David,

 

I am interested in your slider for a similar macro setup (see attached image of A7S in vertically Nauticam housing with a Nikonos mount 3D stereo macro lens). I am using a standard focus rail and it's totally unacceptable for sliding. I've been looking online at commercially made rails with both fine micro slide adjustment and a release for gross adjustment by the push/pull manual method, but don't really know yet whether any of them would be suitable. Are you going to offer your sliders for sale or is it based on off the shelf parts we might be able to buy and assemble? Keep up the cool innovations!

 

 


A couple more shots of the setup I want a better slider for....

I strongly recommend that you use Stereo Photo Maker (SPM) freeware for 3D processing of your images. Once they are joined into a stereo pair SPM, you may adjust the JPEG image in any image processing software. you cannot manipulate RAW images in SPM, but your Fuji does not save them anyway.
