    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...

    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

    52mm NL Pure release date estimate?

    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...
