  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

I don't consider myself an engineer, but I was very careful with this test, using multiple lenses/f-Stops and got pretty consistent results. Sorry about the different sizes of the graphics.

Notes: I used tungsten lights with light blue gel. The Red auto WB set at 4100 and the EX-1 set the same light setup at 3900 for what it's worth. The EX-1 shows artificial sharpening (I couldn't find a way to disable it), but still the resolution seems excellent. Notice that either the B4 mount or the Fujinon lens is contributing a color change.

Red compared with XDCam

Red compared with XDCam

overlaying the Red with XDCam image at 400%, you certainly see the different approaches to sharpening in the two camera designs. I'm pretty confident that if Red did sharpening like that, people would complain it "looks like video". There also seems to be some noise between the lines on the XDCam, is that a compression artifact? "mosquito noise" ?

Note: the EX1 is a 1080p camera, so if this image shows 1:1 pixels on each, that means the 4k Red image would be over 2x wider & taller (more than 4x the area) of the EX1 image, if each were projected at this scale. So this is one technical way to compare them, especially if you were to shoot red and take a 1080 window crop, instead of scaling. But if you are concerned with what it looks like just sitting in a theater watching the image, and you shoot the Red at 4k, I'd argue the more appropriate test would be to match the overall frame size (eg: upscale the EX1 image to 4k, or downscale the Red to 1080p) before matching them up.

Pixel for pixel is very illustrative, although sharpening should be tested as well. This is a good way to compare MTF relative to resolution. Numbers are a game; MTF is what actually measures what you can see.
 
It would be nice to see a Nikon prime lens comparison rather than a zoom, in my experience the primes are noticeably sharper.
