    At what frame size does this mechanical vignetting go away? 7k? 6k?

    At what aperture does it go away? Is there a sweet spot of aperture and frame size that gives round bokeh to edges like the...

    Chris, the pixel pitch of the Helium is 3.65 micron and it implements a scanning CMOS sensor readout. Komodo pixel pitch is 4.4 micron and it implements a global shutter readout. Those two facts...

    Very helpful! I hope that in future RED cameras they implement what SoundDevices does, which is to reserve enough power to properly close out files that are being recorded. Maybe for DSMC3?

    Methinks the Tokina 16-28 kinda completes these lenses. I wonder if Fujinon will make a Premista 18-45 or 16-40...

    In my book, a proper measurement of this sort of chart requires not...

    If you have a Bolt, you don't need the camera to guess focus. You derive and drive focus from the path you program.

    If lens manufacturers published this data (how many mm from sensor place to entrance pupil) it would be trivial for AC to adjust camera position on tripod to the correct location when they are...

    There are times when the subject in front of the lens is so perfectly eye-catching that it almost doesn't matter what lens or camera you are using. There are other times when you depend on the...

    It would be helpful to take a step back and consider what tool is asking to do what job. REC 709, as I'm sure you know, maps a fictitious 10-stop range to about 6 stops of display dynamic range. ...

    There are some copy edit problems on the test pages. For example, the XEEN page includes both reviews of XEEN lenses from some folks, but Canon CN-E (pronounced the same way? I don't know) from...

    Oy vey! I knew that this video was going off the rails at 4:10, and indeed by 4:20 (total coincidence!) it truly did.

    To make these comparisons make sense, you must fix the size of the circle of confusion for the viewing conditions. You can pick a 16K visual monitor with a viewing distance of 1m or a 2K visual...

    Very much don't get too caught up. 200 LP/mm means one thing with an MTF of 99% and quite another at 1%. Most lenses at most apertures we actually want to use really don't have MTF values we'd like...

    They also explain that super-resolution is the dual of de-mosaicing (two sides of the same coin). Remember that BMD introduced...

    This is completely revolutionary! Not only are they selling a 12K resolution camera that shoots decent frame rates for under $10K, but also 82mm branded lens caps for only $15. Amazing!!!

    Take care what you are really measuring. I think Jarred's inbox is so full because $6K is the goldilocks price for independent camera owners, not 6K horizontal resolution. But maybe I'm wrong. ...

    This is a trivially testable hypothesis.

    In a house in the woods, on a clean table, lay out a Raven (4.5k), Komodo (6K), and Monstro (8K). Invite a passing klepto named Goldilocks to enter the...
