    Used ED82

    Received the scope back from Nikon. I will continue to use it as the viewing is still fine.

    Used ED82

    Had the below reply from Nikon. I've asked them if they can check optical alignment and spacing of elements. I am writing with the regards to the repair of your Nikon Fieldscope ED82A and Fieldscope eyepiece lens 20-60X MC2. The technician has been unable to recreate the fault you reported and...

    Used ED82

    Shame as reading through the forums here it seems Nikon ED82's are very good for sample variation. The image is brighter and superior at similar mags compared to my ED50 which I believe to be very good. It's just at 60-75x where the image starts to soften. I have also tried using the MCii zoom...

    Used ED82

    Done a quick star test and I can get 2 or 3 symmetrical rings away from.infinity. Towards infinity best I can get is a fuzzy blob with no discernable rings. ED50 star test has 2 to 3 easily distinguishable rings at both ends of out of focus.

    Used ED82

    Ok, compared brightness at similar magnifications and the ED82 is noticeably brighter with similar/slightly better sharpness than my ED50. Still not getting great sharpness at 75x even on 50m distance targets.

    Used ED82

    Shone a torch inside and through eyepiece hole, all looks clear inside. It's ok up to around 60x, gets dark and loses sharpness at 75x. Maybe I have a really good ED50 and slightly off ED82 as with same zoom eyepiece my ED50 is pin sharp all the way to max zoom.

    Used ED82

    After being impressed by my used ED50 I found and bought a mint ED82 with 25-75x zoom eyepiece for a great price. It is in great condition and looks hardly used, only thing I'm finding is that the image doesn't look as bright as my ED50 (both on lowest mag 13x,25x and highest 40x,75x) Thought...
