@BPMonahan had the same question, did you ever get a clear answer? Thanks!

Hi, this is what I do when shooting with the GH5. Cheers.


1.75x 4:3

1.75x 4:3 5k is 3328 x 2496 = 2.35:1 ratio with a frame size of (5120 x 2179)

1.75x 4:3 4k Photo is 4608 x 3456 = 2.35:1 ratio (4608 x 1751)

(3840x1636) no bars


1.75x 16:9

1.75x 4k DCI - 16:9 is 4096 x 2160 = ratio 3.31:1 with a frame size of (4096 x 1230)

1.75x 4k UHD - 16:9 is 3840 x 2160 = ratio 2.76:1 with a frame size of (3840 x 1234)

57.14% of height

Using 1.75x squeeze on a 4:3 sensor gives a 2.33:1 desqueeze, which is close to traditional widescreen 2.35:1.

How do you guys attach the focuser 8 on a baby hypergonar? What kind of clamp or jacket do you use? @Ian Edward Weir @nahua

I use the Redstan Baby Hypergonar Jacket. Here is one of my setups.

I had planned on doing a big overview and thorough test of the Aivascope before posting anything. But in the middle of my shoot day this happened: Was taking off the magfilter when it slipp

Nice! I got my Aivascope back and am back to filming/testing. Here's something I shot last night. Aivascope/Focuser 8/Mir 1B/G7.  

Yeah, I have had zero issues with the Focuser on the Aivascope as far as sharpness in most situations. It improves everything except infinity on anything longer than 40mm at fast apertures. (especiall
