I compared my Jupiter 8 to my Super takumar 50mm 1.4 and the Takumar is noticeably sharper. I'm using the Jupiter 8 with an adapter on my BMPCC 4k. Is there an adjustment that might need to be made.

Dies anybody have information on the unbranded Prominar 16 for Bell and Howell lense?

I also figure, worst case, If need be, I wait to find one for parts, and replace the back lense.

Well, i just won the auction for $100

Won an eiki 16f in ebay for $200 shipped. Supoosedly in almost new condition. I know they're similar to the Sankor 16f. How does it compare to a Sankor 16C?

Will this small cop in the rear element of a Sankor C effect the image?

How do the single focus Bell & Howell and Sankor C compare to each other. Does anyone have experience with both. Wondering about sharpness and lens flare etc.

I only want it for the Jupiter 8. Thanks for the info.

I want to use it with my BMPCC 4k. It has an MFT mount. Is there an adapter I can get for it?

I have Jupiter 8 lens that won't focus at all. I'm using it with an M39 to EF adapter. The only thing it will focus on, is extreme close up. Like a crazy macro lens.

I've been using the XTPower 20000 fir over a year. They are identical to the juicebox, for less money. https://smile.amazon.com/XTPower-XT-20000QC3-AO-PA2-Power-Bank-Automatic/dp/B07PKSBS7J/ref=sr_1_3?crid=20AORIRM77WVU&dchild=1&keywords=xtpower+xt-20000qc2&qid=1594002316&s=electronics&sprefix=xtpower%2Celectronics%2C201&sr=1-3
