Ever since the original Canon 5D MkII opened up the world of accessible large-sensor video, it’s been hard to stomach the reduction in field of view that a cropped sensor demands. I absolutely love the image quality that my Blackmagic Production Camera captures, but the 1.7x crop factor made it a challenge to keep working with the same lenses that I used with my 5D2.
For example, my go-to lens for wide-angle handheld work with the 5D2 has always been the Canon 20mm f/2.8, and my favorite general-purpose lens is the Canon 24-70mm f/2.8. But neither of those lovely pieces of glass work the same way on the BMPC, because of the crop factor.
After investing in a couple of new lenses (plus digging an old 8mm Peleng out of my closet), I set out to do a side-by-side comparison to determine what lenses I can count on, and which I should leave in the bag.
First up was the Peleng 8mm. I bought this Soviet-era marvel years ago to use with a Krasnogorsk 16mm film camera. I had used it for a couple of fisheye shots on my Canon 5D, but I’ve really never had much use for it.
Here’s what it looked like. For each lens, I’m showing a scaled-to-fit image and a 100% crop from the ProRes HQ 4K video file.
While the ultra-wide angle is impressive, and the vignetting could be dealt with, the lack of clarity in the image would be hard to justify for any serious production.
