At 1:31 you said "Now we are recording full HD, with the center crop mode, no doubler added on the lens, Super 35 sensor has been completely covered..." That is false, of course. The Super 35 sensor is *NOT* covered, which is why you had to engage the crop mode to get a full image. Also, you don't "lose any light" using the doubler. The doubler just spreads the light out over a larger area, which makes the image darker. The doubler doesn't change the lens's aperture diameter nor how much light it captures from the scene. The doubler does double the f-number, which is just a mathematical consequence of the focal length being doubled. (N = f/D)
FS7 on centre crop mode HD has proven to be a substandard image for me. (S-35 lenses) My preference instead is to shoot 4K internally and HD externally via a docked SDI Samurai Blade SSD recorder. Both 10bit 422 and both with identical Timecode.
@@CraigMarshall_HDvideo4K Oh I see. Yes I don't like the centre crop HD either. That's why I used the MTF adaptor for B4 lenses because it covers the whole S35 chip, and in doing so allows B4 for 4K in the FS7!
Hi, thank you for this useful video. You mentioned you could use a EF-E Speedbooster adapter instead of the mtf one. Would it technically work to use a combination of speedbooster+ef/b4 and what would the picture look like? Many thanks and merry Christmas!
I'd be curious too. I just picked up what looks to be a similar lens (HJ17ex7) and am hoping for some good news about what my EF speedbooster can do for me once my B4 to MFT mount arrives. Thanks!
So, even with the dummy adapters is possible to get rid of the vignetting? I want to adapt my B4 to my Sony a6400 which is an APSC sensor, I was thinking about use the 2 times extender and the clear image zoom, it can work like that?
