Mamiya 645mm Speed Booster for RED from Optitek test

It gives you one stop of light + 0.33 wider field of view on your Red camera.

Another test with 300MM 2.8, 200MM 2.8 apo, 45mm 2.8, 110mm 2.8 is coming up.

Right now, my mamiya set up is getting f 2.0 in entire prime range without 35mm 3.5

This will be my favorite set up for a long time

Thank you Minu,
That looks good. We had a lot of film makers asking for footage. Finally they can see the images these lenses create...

Dope, thanks for sharing, bought to snag up a 80mm 1.9 before they gain too much popularity.

This looks great. Is there a specific mamiya speed booster? On the site, I see one for Pentax and Hasselblad.

 

[Jacek Zakowicz]

Yes there is. We have made Hasselblad, Pentax 645, Mamiya 645 so far... We can make Pentax 6x7 as well...
