Post processing of the images was identical for each image of course, otherwise the whole thing would be quite pointless. All the camera settings were constant and manual, as described.Generally there is only one "point" in each binocular to focus upon to get a sharp edge of the image. Seems to be the baffle below the ocular to me. I guess the biggest mistake in my series comes from a slightly different focus distance in my photography lens depending on the binoculars light path and ocular baffle position. I generally had a focus distance of about 0.5m, that is macro mode, and the same lens focused at at 0.35m for example would have less light hitting the camera sensor. In fact, this would explain why the 8x32/30s appear darker, as their light paths should be a bit shorter than in the 8x42s, so I needed to focus closer. The thing is getting more complicated as the porros should have a different light path length than the roofs, so my focus points would differ slightly. For the 8x42s, I see much less of a problem, as they are similar in length and flightpath probably, so my focus point was similar enough. Anyway, I started the whole thing because I wanted to check how far the SF8x42 is off in colour...In fact, as Chosun pointed out, the Habicht appears way too dark, and with it the whole 8x30/32 series. I need to amend this in the discussion. It does not contradict my visual experience though, within the 8x30 series and elsewhere, and no matter how much I like the Ultravid 8x32 HD Plus otherwise, it is darker than expected, if compared to the state-of-the-art 8x42s. Gijs van Ginkel seems to plan to do transmission measurements comparing HDs to HD Pluses... A 8x32 should have the same light density in the image as an 8x42 at full aperture, otherwise we could not reasonably use them, they would always be much darker than the 8x42s - which is only the case when our pupil size becomes bigger than the exit pupil. Or am I missing something here. I don´t see yet what stopping down to 2.5mm would improve. Chosun, about darker images appearing more contrasty, I am confident this is a perceptual principle, I will post a comparison soon, image at same contrast ratio in different brightness levels, and what appears most crisp. Nikon SE, E2 and 8x42 EDG are all pretty dark binoculars compared to the more updated competition, but have a reputation of being very crisp and high contrast, and they might in fact be more pleasing to use in very bright conditions like South Africa or California, compared to often dull middle and northern Europe or Alaska.</blockquote>
