    First image of NL x52's!

    Is curvature of field a good thing?

    Exactly, and this effect allows companies such as Steiner to claim, e.g., that their IF Navigator 7x30 features a "sports auto focus", which is complete rubbish of course, but nevertheless it works well in the way described by Binastro, i.e. the strong field curvature allows observing closer...

    Product Review: The Sky Rover Banner Cloud 8 x 42 Binocular

    Well, I tested for my own curiosity and benefit whether sharpness is equal, and it is not (Product Review: The Sky Rover Banner Cloud 8 x 42 Binocular), so for me, the world appears to be in order: if you want the best of the best, it’s going to cost you more than $ 500 … (I still grapple with...

    Mid-level 10x50 (Maven B6) vs Alpha 10x42 (Noctivid)

    Joking, right?

    Version identification of the Kowa Highlander

    The "Prominar" version of the Highlander is marked "Fluorite Lens" at the side of the tubes, see pic. I bet there is quite a difference in CA correction compared to a non-fluorite version. Canip

    Change to Zeiss SFL 10x40 or stick with my Leicas

    Shouldn‘t we also start looking for rings in other colors? My preference would be gold …:unsure:

    52mm NL Pure release date estimate?

    The timing should work, as I understand the signals, but which model are you referring to by „these“?

    Product Review: The Sky Rover Banner Cloud 8 x 42 Binocular

    NOTE: the following makes no claim to be a scientifically reliable finding (I have been using my own eyes;)), nor is the result in any practical way relevant for birding or any other activity during which you engage a binocular. Like many others, I have said before, and say it here again, that...

    10x42L vs Nikon MHG

    I would even say MUCH better (than, e.g., the Canon 12x32, which has a lot of CA for my eyes)

    Vignetting in Binoculars

    Discussion in a nutshell: Is the SkyRover "worse" than the NL? Not noticeably in my view. The Junior seems okay, the Visio quite good, the APM appears good at first sight but then exhibits several other anomalies The Bushnell with its huge prisms exhibits little vignetting, the Olympus even...

    Vignetting in Binoculars

    Interesting topic, John! Brief remark about terminology: I guess the term "vignetting" applies to all situations in which peripheral rays are obstructed. It is therefore also used for the "square shape" vignetting in porro binoculars which exhibit the use of BaK-7 glass vs. binos with BaK-4...

    Poll: will you buy Swarovski AX Visio?

    Couldn't recently take along the AX Visio, but managed to squeeze the Powershot Zoom into my pocket, and on my way crossed path with this nice grey heron. The big advantage of the small Canon, beside the 400 mm focal length, is the short time within which it is ready to shoot, took my about 5...

    Change to Zeiss SFL 10x40 or stick with my Leicas

    Since most here advise you to switch to a new bino, just one dissenting opinion, for what it‘s worth: The BN is one if those great binos from the era when Zeiss, Swarovski and Leica used to make binos that were optically very good, were not fraught with mechanical issues (focuser, diopter) and...

    New "MY Junior" 7x28 aimed at kids

    You bring up an interesting point, Hermann: Why is the need to adjust the diopter not the same in all my binoculars? As mentioned, it varies for me between 0.5 and 1.5 dpt, depending on which bino I use. Of course, not all binos exhibit the correct amount of adjustment (and the right „0“...

    New "MY Junior" 7x28 aimed at kids

    It is. It doesn‘t. I have been using it today out in the fields. A bit more field of view would be welcome, 50 degrees AFOV isn't huge (but I am pretty sure for kids it's better the way it is), otherwise a pleasure to use. Nice sharpness, bright image, natural colors, little CA, even...

    52mm NL Pure release date estimate?

    That's not what I expect, based on what I hear from my sources (well, two of the three numbers in the above quote seem correct). So as the launch date comes closer, there remains a bit of surprise potential in the system, and that's a good thing.

    New "MY Junior" 7x28 aimed at kids

    Same here, on almost all of my binos I need to adjust the diopter by between 0.5 and 1.5 dpt, but I don't feel the need with the Junior, whatever the reason (my optics dealer was equally puzzled). Pleasant easy-going bino with no immediately noticeable flaws, a pleasure to use, field of view...

    52mm NL Pure release date estimate?

    Not sure China is there yet, but just wait until the EU makes biodegradable armour mandatory, they have done similar things in the past. Could also first happen in California …. The intention sure is good , but I sometimes wonder about priorities …
