    Help! Coatings on Victory SF being... weird?

    Note that the angle of incidence matters here: The incident light hits the objective lens almost head-on, with deviations of +/- 4 degrees or so. The color differences in the coatings often only appear at an oblique angle, which plays no role in the formation of the image. Cheers, Holger

    Swarovski NL 8x42 vs Skyrover apo 8x42 sharpness contrast microcontrast etc

    I have no doubt that the SRBC are significantly better (optically) than any of the subalphas and rather closing up towards the alphas. Cheers, Holger

    Swarovski NL 8x42 vs Skyrover apo 8x42 sharpness contrast microcontrast etc

    Exactly! These direct comparisons are necessary and they will surely come up over time. At the end of the day, it doesn't really matter which one is 'better' (is it actually possible to decide whether a Zeiss SF or Swaro NL is the 'better' one, being as close in their qualities as they are?)...

    The APM 6.5x32 ED IF, compared to the APM 6x30 – A Few Thoughts

    Same here, a Porro of good performance is something that always makes me happy! I may nonetheless get the 10x50 Banner Cloud, too good to be missed out ... Cheers, Holger

    The APM 6.5x32 ED IF, compared to the APM 6x30 – A Few Thoughts

    My APM 6.5x32 arrived just today. I won't have much time for testing in the next few days, but I can already guess that using this new binocular will be fun! It probably looks like a Fujinon FMTR-SX would look like without its rubber armor. Slightly shorter than the 7x30 BPO. Cheers, Holger

    Sky Rover Banner Cloud 8x42 APO Review

    During the time when I lived in China, from 2005 to 2016, I occasionally received binocular samples from UO for field testing. After I had collected my experiences with these samples, I sent them reports in which I complained about various issues that I had encountered, and among the most...

    Trinovid hype

    Although the Trinovids and Dialyts of the 1960s-1980s were not actually waterproof. Surely not better sealed than the Oberkochen Porros. But compactness, or better slim body design, was certainly a selling factor. Cheers, Holger

    Trinovid hype

    I agree with Canip and Henry. That roof prism binoculars without P-coating could not compete in terms of resolution with Porro-type binoculars of similar quality is a scientific fact that was known to the manufacturers (and to a few scientists) since the 1940s. Pointing out this fact has nothing...

    Holger’s Binocular Book - in English in 2023!

    Yes, this makes sense. I will prepare a concise introductory chapter similar to the one existing in chapter 2 of the German edition. Then I will convince Springer that such an addition is needed for the next edition. Thanks for your suggestions! The prohibition of binoculars (and other military...

    Most color strength in a binocular view?

    It all seems to be related to the particular spectral transmission curve of the binocular: Some observers have noticed that the color saturation seems to increase whenever the transmission is high in the long-wavelength limit, that is red and orange. Most binoculars have their highest...

    Holger’s Binocular Book - in English in 2023!

    This is a valid point and it is going to be considered. I found it somewhat inappropriate for a book of the Springer Physics series to have such an intro, but it may not be impossible. We are receiving user's feedback and we do collect reviews and are going to discuss implications when time for...

    Holger’s Binocular Book - in English in 2023!

    This observation is correct: The German edition had an additional introductory chapter and chapters for 'choosing and using' binoculars. From the very beginning I had decided to discard the chapter 11 because it described binoculars available on the German market but none of the brands that...

    Holger’s Binocular Book - in English in 2023!

    I agree that such a plot is of very qualitative character - it is just supposed to show the general trend that makes the rule of diminishing returns. No overall performance can reliably be cast into a single number, and there will always be individual products which offer outstanding...

    Choosing & Using Binoculars arrived!

    I have now received my copy of Choosing & Using Binoculars by Neil English! Before I had seen major parts of a pre-production version of the manuscript, but now, having this formidable 520+ pages book in my hands, I am all the more impressed. What a wonderful selection of binoculars Neil has...

    Book Review: The Binocular Handbook: Function Performance & Evaluation of Binoculars by Holger Merlitz.

    There is an Uppendahl in that 7x24 Rangemaster - a surprise indeed, thanks for the info! I have been semi-aware of the still present 2nd generation Geovid, but assumed that this would be old stock in the process of being phased out and soon to be replaced with the 3rd generation. If there are...

    Book Review: The Binocular Handbook: Function Performance & Evaluation of Binoculars by Holger Merlitz.

    Seems Springer keeps on hiding some Easter eggs for us. Thanks for this one, it is recorded and will be reported to their production team. Cheers, Holger

    Book Review: The Binocular Handbook: Function Performance & Evaluation of Binoculars by Holger Merlitz.

    On the Springer page it is definitely shipping. Maybe, it is easier to cancel the Amazon order and get it directly via Springer. Cheers, Holger

    Book Review: The Binocular Handbook: Function Performance & Evaluation of Binoculars by Holger Merlitz.

    Thank you so much, Neil, for reading and promoting my book! You even forgot to mention that your own book, Choosing & Using Binoculars, seems to be ready for shipping, too (if I am not mistaken)! Some of you guys here may wonder how comes that Springer publishes two new binocular books...

    Holger’s Binocular Book - in English in 2023!

    Thanks Peter! Yes, it has been a long process. In 2015 I have already been thinking about making that English edition, but then postponed the plan while I worked on the 2nd German edition. Canip kept on pushing me and he was even so kind helping me translating some sample chapters for the...

    Holger’s Binocular Book - in English in 2023!

    Actually, my German edition also has a binocular sketch on its front page (a Leica Noctivid; the 1st edition had a Swarovski EL). Well, they gave permissions to use these pictures, and that was it - I didn't receive money for that. But the 2nd edition has a double-page advertisement featuring...
