    How many of the potential raptor species for the U.K have people seen?

    Buteos are so dependent on thermals - as we all know, the well-known choke points really act as bottlenecks for these and similar species. Harriers funnel through the same places, of course, but whenever I've seen them they have always seemed to have a more effortless flight. I'd hate to be...

    Svbony sv 202 8x32 vs Opticron Adventurer t wp 8x32, which is better?

    Before we start getting all misty-eyed about those old Jeeps and Land Rovers and go rushing out to buy ex military IF designs (the binocular equivalent), it might be worth having a think about what you actually want to do with it. If you need something to go on safari with for the next 20...

    Brief review of Fujinon HC (Hyper clarity) 8x42

    Interesting report, thanks. I agree with jackjack that as you go higher in magnification it seems harder to arrive at the clean, well corrected image we all seek. This can be seen even going from 10x to 12x, and I well remember looking through a Celestron Skymaster (20x80?) or one of its...

    How many of the potential raptor species for the U.K have people seen?

    I have doubts over F. cherrug (except as falconers' escapes) - the species is in trouble in E Europe, by far the most likely area for vagrants to appear from. Bonelli's - wouldn't one have showed up over the last couple centuries when they were more common than they are now? Griffon is...

    How many of the potential raptor species for the U.K have people seen?

    On the subject of historic records, what does our esteemed readership think of the claims of American goshawk (now considered a separate species of course) in Ireland and Scotland? (link)

    APM MS-6x30

    Sorry you didn't get along with it, but that's fair enough; some folks just cannot get along even with the very best binoculars (someone here was reporting huge issues with the SF 8x42). I do exactly the same when looking through binoculars - like when reading a book or looking at a computer...

    Shanghai, China, today

    I have no idea about the presence of this species in Shanghai but it's definitely found in park-type urban habitat in Singapore and can turn up in some pretty surprising places - I was certainly surprised to see one hopping about near Raffles Place MRT station late at night one night, about as...

    Nikon SE

    They won't, but if water keeps getting into them, you're going to have haze and probably fungus issues in the medium term - see first hand report from this chap in New England (link). Being rained on is one thing, they're shielded quite well and can probably handle that (would put them away if...

    Let’s talk about eyecups (comfort, dimensions, preferences, etc.)

    Long eye relief lets you see the full field of view if you put the binoculars further from your eyes (as you must do when wearing glasses/spectacles). But if you don't wear glasses, overly long eye relief can lead to blackouts (which can even happen when wearing glasses, for instance with...

    CZJ T3M

    That's my understanding as well. But Tringa (if I understand his posts correctly) was talking about metalizing the other surfaces. To me it seems that would make no difference, given that total internal reflection would have taken place off those surfaces ... but I'd be more than glad for...

    Haven't there been well over 382 days since December 16th 2022?

    Gotcha. But what would be the benefit of metallizing those other surfaces, given that total internal reflection would have taken place there?

    Nikon HG 8x30 dissection

    There should be no need whatsoever to get defensive about one's choice of binoculars (cf seawatcher's last post). Light binoculars have been around for absolutely ages (eg Zeiss Turactem and others from the 1920s). If anything top tier 8x32 binoculars have been getting larger and heavier, such...

    Perhaps another game changer

    ... and I do agree with what you say. But the exceptions, like this fine chap, have a way of standing out from the norm... interesting point - how quickly can one tell that (a) one likes a binocular, and (b) how it compares to other binoculars you're familiar with? In my own experience I have...

    ... but they did, didn't they? Before the introduction of dielectric coatings, mirrored surfaces on Schmidt-Pechan prisms had to have been metallized - either aluminium (some Leitz) or silver.
