BINOCULARS. COMPARE ZEN-RAY 7X36ED2 & 7X43 ED3.
Mar. 7th, 2013 at 10:45 PM
Compared Zen 7x36ed2 & 7x43 ed3. x43 noticeably heavier, although technically the difference is not very large (as with 8h43 ed3). In his hand are both well. comparison was carried out on a clear day when the sun is gone, so that on the one hand, there was not a lot of light, but, on the other hand, there was enough light to see all the details and evaluate the chromatic aberration (at very low the light is not visible, but with a strong barely noticeable).
Sharpness and contrast a little bit better at x43.
x43 have a level field and a few sharper edges, and the decline of field begins (in%) later. Simply put, a clear area of the field, in% more, but about the "clarity from edge to edge" to say no.
At the same time, even given the fact that the field of view of x43 is clearly smaller than the x36, for binoculars with a field edge sharpness is very good.
Same goes for x36 - more blurred edges and blurred starts (in% of the field) before, but the field more.
Yes, here at Nikon EDG ... but we are not about Nikon. and zeiss 7h42, according to reviews, is roughly the same region. Grace. Day, bright day, looking at the ships in the roads, the distance to the house, my glance at the trees on the slopes, and a small difference is visible, even if you do not go into the semi-darkness under the high treetops. The difference is very small during the day, but there is. At night, there will be more. Both Xena - one of the brightest roof models in its price range. chromatic. Great subject - the white foam of the surf in dark gray, with dark green, almost black moles. A bit of light, there is nothing to mask the chromatic fringing, but it is more than enough to see any detail. Small chromatic distortion visible in most parts of the field as in x43 and x36 with. It seemed to me, in their x36 bit less than the x43. What is important, even on the edge of the field chromaticism did not reach that critical level when the picture is just too unpleasant to consider. Both binoculars chromaticism is at an acceptably low-level. For less critical images (eg, more sun) chrome practically invisible. Branches of trees against the sky - chromaticism meager or even invisible. (The sky is something much lighter.) Eye relief is quite large, it is possible to speak of about 3 mm difference with the x36. As a result, without removing the lenses can be seen almost every field. And quite comfortable seen. Unfortunately, increasing the removal of the pupil, the engineers forgot Zen increase the range of adjustment of eye cups, so that the glasses are very comfortable, but no points if the rest the eyecups in the face, or even just to bring almost back to back, getting funny blackouts. If alienate x43 on behalf of those most about 3mm, then everything will be fine, but keep it uncomfortable. x36 with no points - very convenient to watch and glasses lost 15 ... 20 percent of the field (depending on the points and they sit). "amateur Council "with birdforum to lengthen eye cups on x43 solves a problem for people without glasses, but ochkarikov binoculars abruptly becomes less convenient. And do what you want. Focusing in x43 is very fast and sharp, small wheel turn it significantly changes. Hence it follows another point. There are binoculars option that virtually none of the manufacturers of binoculars in the specification clearly and honestly is not documented, it is a complete margin diopters when focusing at infinity (and vicinity). I'm talking about big minus infinity. x36 We reserve is huge - with a large red, and in the black, there is a considerable margin of diopters, with stepless adjustment allows it to build up very accurately. At 8h43 ed3 margin nearly as well, or at all slightly less (subjective assessment). And here at 7h43 range of adjustments decreased slightly sacrificed "fast focus", so there's margin of minus subjective, became a little less for a couple of diopters., that is. (If someone that are important details to tell). Finally, a subjective parameter - the comfort of images and observations. Both 7x it is very comfortable, enjoyable (as for me) than most 8-rock.
