Re: Laowa MSC Magic Shift Converter

It can't create imaging light from nowhere. It spreads the image just as a TC does, the difference being the extra image circle is not blocked by baffles & the mount is designed to move to make use of the larger circle.


If you re-read the second article you linked too you should see:
'converts the Laowa 12mm f/2.8 Zero-D to a 17mm f/4 lens with +/- 10mm Shift capability without any vignetting'
12mm to 17mm looks like a change in focal length much the same as produced by a 1.4x TC & the 1 stop change is entirely consistent with that.

Quite right. Too many other distractions here this week. I haven't even taken any pictures through the converter, after many months of waiting.

Even at 17mm, that is a wider shift lens than I had for film, where I had/have 24mm. Knowing how a 17mm rectilinear is a bit of a beast to use to full advantage, a shift version could be quite interesting.

Of course, all those lenses are normal FL direct on the camera.
