    25-50x eyepiece diameter?

    Hi Northman I see you have had no replies to your enquiry. I suspect that you may have found the answer elsewhere by now, but I have recently acquired an ATS80 with a 25-50x eyepiece, and I have just measured the diameter at 52mm. Cheers

    Fuji XF 70-300 f/4-5.6

    The new 70-300mm lens is an excellent addition to the Fuji XF lens line-up. The fact that the 1.4x 7 2x TCs can be used with it adds a valuable extra dimension. Since I obtained my copy it has been my most used lens.

    What to use when your 8x binoculars aren't powerful enough?

    Nikon ED50 (or similar) with 16x or 20x eyepiece plus a shoulder pod might be an option.

    Bird species seen just the once in your yard/garden.

    I had a Black Redstart (Phoenicurus ochruros) on my shed roof in my suburban Sussex garden a few years ago - stayed for about 10 seconds.

    When you install the Swarovski head rest should you hear a click?

    SF 8x32 v NL Pure 8x42

    Thanks for that information - very helpful. As you also say, weight is a major consideration. I hope to be able to try both models before too long.

    SF 8x32 v NL Pure 8x42

    I know that the lack of reference to Swaroclean on the NL Pure has been touched on briefly in another thread, and I am also aware that it is a coating that perhaps has no meaningful effect on the optical performance (hence may not have been identified as present by Swarovski in their technical...

    Review: Zeiss Victory SF 8x32

    Great review Lee - thanks. I am greatly looking forward to the day when Park Cameras is open again and the SF32 is in stock. |^|

    Beetle ID

    Many thanks - very helpful.

    Beetle ID

    Actually, I am now inclined towards this being one of the Flea Beetles in the genus Altica. Any thoughts from others would be most welcome.

    Beetle ID

    Hi All I am looking for an ID on this specimen, seen in West Sussex today. I suspect that it might be a Blue Mint Beetle, Chrysolina coerulans and I would be most grateful for a confirmation or correction as appropriate.

    ED50 20x or 27x DS question

    I have an ED50A (as well as an ED82A) and I use mine almost exclusively as a travel scope. I use a 20w for 95% of the time but I also take a 40x/75x (old style MC with fold-down eyecup) and use it for more distant viewing as required. In good light the 40x is very useable in my view and I would...

    Best Scope Size

    Hi Lee I'm not sure how practicable it would be to fit a WA zoom of another brand to the Nikon. Eyepieces are connected with a screw thread of limited diameter. Someone may have done this however - perhaps with the Baader? Nevertheless, I find that 30x suits my needs in most situations so this...

    Best Scope Size

    I have a Nikon Fieldscope ED82A which I think is pretty much ideal for use here in UK. The only downside is no wide-angle zoom eyepiece but I love the prime MC eyepieces. The view is fantastically bright at 30x which is what I use 90% of the time. I will put on a 50x or (in good light and when...

    Always used 10x but thinking about switching to 8x

    I switched about 11 or 12 years ago. I swapped Swaro EL 10x42 for Zeiss FL 8x32 and have never missed the higher power. There is a lot to be said for a wider view and less need for fine focusing.

    Zeiss binoculars accident

    Sounds to me like there is some damage to the focus mechanism. I think it would be best to send them to Zeiss to sort this out.

    Cotopaxi Ecuador American Kestrel?

    I meant to add that the map in Ridgely & Greenfield suggests that it should occur at Cotopaxi.

    Cotopaxi Ecuador American Kestrel?

    Ochthoeca fumicolor looks a good fit to me. Ridgely & Greenfield give an altitude range of 2800-4200m. On Habits they say "Found singly or in pairs, often perching conspicuously atop a bush, small tree of Espletia spike". One I missed when I was there in 2015.

    Redshank Uk

    Apologies for differing, but I suggest that the length of the legs and the bills indicate that these might be juvenile Black-Tailed Godwits rather than Bar-tailed.

    Tripod for Nikon ED82 ?

    Slik Master is another option - quite heavy but robust and reliable in my experience.
