This Guy Made an 8×10 Large Format Video Camera

Photographer Zev Hoover has created a rather unusual camera: it’s one of the world’s first 8×10 large format video cameras.

Hoover believes his creation is the first of its kind ever made. The company LargeSense showed off a 4K sample video shot with a large format digital camera back in 2015, but that involved an expensive digital sensor and was made by combining TIFF file readouts from the sensor at 24fps.

Hoover’s camera, on the other hand, is much more affordable and practical for everyday people. The front half is an old large format still camera built around a cheap video slider for adjusting focus during shooting by moving the lens and bellows forward and backward.

On the front of the camera is an old Ukrainian large format lens that projects an image onto the white plane at the back of the camera. A separate digital camera is then placed underneath the large format camera, capturing the image on the white plane through a hole and using a wide-angle lens.

“The camera works by projecting a huge (bit over 8×10) image — with all of the lovely depth and aberrations of large format glass — onto a matte surface, like a perfect projection screen,” Hoover tells PetaPixel. “I then reimage that plane with a wide angle lens (Irix 15mm f2.4 Firefly) on a Sony a7S.”

To compensate for the fact that the video camera is capturing the white plane at an angle, Hoover uses 12mm of shift.

Hoover can also attach an external monitor that allows him to shoulder mount his hefty camera contraption.

Here’s a 4-minute video Hoover made that shows sample footage from this camera and an explanation of how it works:
