Difference between Oscillo Raptar 0.5x and 0.9x

[kymarto]

One of the more common oscillo lenses is the Wollensak Oscillo Raptar 75mm f1.9. However there are at least 2 different versions (and I think maybe at least one other). The two I have are the 0.5x and the 0.9x. I finally got around to doing a direct comparison between the two, and the results surprised me. Ignore the fact that the camera is not level, please. Have a look. SOOC

Thanks a lot for the comparison. I didn't know there were two version of this lens... I wish I had even a single one

I've seen some really interesting shots made with the Oscillo Raptar 75 mm - seems like a great lens to experiment with.

I only have one of them, but certainly interesting ones!

I also didn't know this!

Do you count the Oscillo-Anastigmat as the third version?

I have one of those and interestingly it has a more conventional bokeh.

Did the Raptars replace the Anastigmat perhaps?
