Notes

Most of the comments made about the 6030 apply to the 4030 as well.  Lumen output is lower than the 6030, except when at full telephoto zoom.  Grayscale is okay right out of the box and is similar to the 6030 in this regard, with too much red and blue in the higher IREs, while being deficient in green.  However, it calibrated very well (see graph), with Delta E at 1.5 or less for the entire range.  Unlike the 6030, the gamma setting in the 4030 was right on (0 equaled 2.2).  There are extensive gamma settings available, but gamma is so consistent, most people won’t need to use them.

The Quick Cal of Dynamic reduces the green that’s apparent in whites, but each decrease in Green Gain causes a drop in lumen output and eventually starts to looking red with light grays.

The color gamut is quite good by default in Natural mode, better than the 6030, with both Yellow and Green closer to the Rec. 709 target mark than they are in the 6030.  Green was still off in hue and saturation, and Blue and Cyan were oversaturated.  The other colors only required slight adjustment.  Skin tones ended up looking good and like the 6030, you can always use the skin tone adjustment if you like a little more or less red.
