Thanks Blaine, glad you liked it!

Awesome but that price is expensive

I have been using a cheaper Mamiya 645 lens adapter Fuji GFX body but run into a lot of 'blooming'. In your video you seem to have the same problem, at 11:18 for example, look at the pattern lines on her vest. I was hoping the ripon speed booster remedies this, because they advertise that it somehow 'makes the light fall onto the sensor more vertically'. Apparently digital sensors struggle to cope with the more 'broad' way film lenses project light onto film. Did you know about this? Do you or anyone here have a solution for this?

👏👏👏

Great video! Been getting into adapting my old lenses onto new cinema cameras. However, I'm still a little bit confused about the crop factor. Let’s say I wanted to adapt my mamiya 645 lens 55mm (35mm equivalent in full frame) to my full frame camera without a speed booster. Do you know what the crop factor would be? Also with the speed booster, would there be no crop factor for the focal length? THANK YOU!

when ur not using the speedbooster theres no „equivalent“ thats relevant. on a FF camera a 55mm medium format lens has the same field of view as a full frame 55mm lens. when you use the speedbooster its a 35mm full frame lens equivalent

I'm just wondering... would it work to take a Pentax 6x7 series lens, the Kipon P67 0.7x focal reducer, and then put a Laowa 1.33x front anormphic adapter (77mm rear thread, and 48-100mm recommended focal length range, so would suit the 55mm f4, 90mm f2.8, 105mm f2.4 and maybe even the 135mm f4) on the front to squeeze more of that huge image circle onto a full frame sensor? That would be some image... I ask because I just bought a P67 to L mount Kipon focal reducer for my BMCC6K, and was thinking "why?" since it will only give the same focal reduction as can be achieved with the smaller Mamiya or Pentax 645 lenses... so the P67 look will be unachievable (though no doubt still beautiful). But if the Laowa front adapter squeezed more of the P67 image circle into view of the full frame sensor, then you might benefit from the larger lens format... but I'm not sure if optically this works or not (ie would the squeeze narrow the image circle that hits the Kipon focal reducer optics, or does it instead widen the horizontal field without affecting the image circle)? Appreciate your thoughts... another option is to use a 0.8x wide angle converter on the front, but I like the idea of some amber anamorphic quality mixed in with medium format optics... PS: I've just sent the same question to CVP as they're a stockist of the Laowa adapter... will drop their answer here when I get it.

Hey Thomas, to answer your first question, yes, the Laowa anamorphic adapter will work with this focal reducer. I have the Aivascope, and it works. In terms of 67 vs 645 focal reducers and anamorphic adapters, that's something you'd have to test in person to get any sort of definitive answer. There are so many factors such as distance between the spherical taking lens and the back element of the anamorphic lens or the size of the glass elements. I believe as long as the image circle covers your sensor without an anamorphic adapter, you'd just need the focal length to be the proper length for the anamorphic adapter, to not vignette but again, it's something you would need to test yourself. Maybe you'd find some interesting results.

@@dripps Hi, thanks for the fast reply. I've had a reply from CVP this morning, and their view (without testing) is that the main problem might be vignetting with wider focal lengths - but as you say, I'll need to test. I've already bought the focal reducer from Kipon for P67 lenses (on its way to me), and decided which lenses I'm initially going for (45mm f4 and 105mm f2.8; I might add the 55mm f4 as well). I've asked if I can go test my setup at CVP's London showroom before committing. Whilst the 45mm lens has an 82mm filter thread, online users of this lens report that they use it with 82mm to 77mm step down rings for filters, with no vignetting (these lenses are used with tilt shift even on the P67). Clearly that's on a P67 camera, but it shows the huge image circle of the lens. I'm hopeful this setup could work, but will only know after testing. I was just watching Mathieu Stern's review of anamorphic adapters, which doesn't include the Laowa unfortunately. But the Sirui 1.25x or Moment 1.33x adapters also look like good options. The Sirui has the advantage of smaller squeeze, which might be a good option if vignetting is a problem. And I like its more subtle flares, as I'm not really into the flares so much. Thanks for chiming in.
