[QUOTE="Tobias Mennle, post: 3319511, member: 117315"] Well, I started a journey with this. Some errors and ommissions: Sure, with natural light we cannot compare brightness. I just wanted to start with colour. The chart I posted first had two faults: 1. The Ultravid 8x32 is totally off. Other measurements showed it is indistinguishable from the 8x42. 2., the chart was slightly oversaturated due to a fault in postproduction. I corrected this and attached the new table. Again, this is for colors, not brightness difference, but I adjusted brightness of all images to the same level (50%) for a better comparison by putting the peak of the narrow tone curve on the 50% line of the histogram. Also, I compared images taken on two different days. Why the Nikon EDG and the Ultravid looked almost identical, the Zeiss HT and SF looked quite different on a sunny vs a dark overcast day.... Next step was to do a comparison indoors with professional halogen light used for filming. It turned out that the light spectrum is far off from sunlight, so this is not a feasible approach, but you might like to have a quick look on a comparison of 12 different bins... Third step, I have just tried my lightbox as a light source, and this looks almost indistinguishable to the daylight results, so I will use this as my setup with fixed distance etc. and it will be good for comparing brightness, also. This should work, and I will do a new try tomorrow as I really want to get rid of some of these bins... To Vespobuteo, I agree on basically all your points in your analysis. Although brightness should not be compared at this stage, yes, the SF looks as bright as the HT, and the EDG much darker, the Ultravid as bright as the Zeisses. The E2 is really dark to my eyes, so was the SE, which I used to call "Black Hole" compared to my Habicht. High transmission vs skewed transmission/colour cast, the Ultravid looks almost identical to the EDG in colour cast, but so much brighter, so for me it is a proof that it can be done - to boost transmission and achieve a much greater image from it. So hats off to Leica for this one. If coatings are more important than new "HT" glass I would love to know. Maybe they are. Thanks for all your feedback, also the private one. I´ll also attach the first brightness comparison of the 4 8x42s, still done in daylight, but the halogen light result looked very similar. [/QUOTE]
