    Terrible Opticron 8x50...

    Tenex, I have to admit that I did a bit of a double take when I saw your post as I knew when you said "8x50" in the title then you had to be referring to the Discovery. The double take was because I have now found myself often using the 8x50 Discovery as my Opticron model for birding. I...

    MM4 77mm

    Chris, These were just comments/experiences so far. I will write something more extensive up when I have time. To answer your question, it is certainly on par with the 60 mm version with the usual caveats when one is comparing a 60 mm with a 77 mm (higher magnification range and subsequent...

    MM4 77mm

    As promised, here are some pics from the three scopes mentioned previously. I used the magnification settings on the eyepieces of each scope so my apologies if the image magnifications are not exact. I also used the 28x wide angle eyepiece with the Opticron as that is what I typically use for...

    MM4 77mm

    The video was shot with the 28x wide angle eyepiece Lee. Related to what I said previously, I did do a side by side comparison between the Harpia, Gavia and MM4 77. Will post the pics later today or tomorrow as time allows.

    MM4 77mm

    I had a great deal more time to play with it yesterday at the Cape May Bird Observatory’s optics sale and did compare it side by side with the Zeiss Conquest, for example. I am hoping to do some phone oping pic comparisons today as well. Here is a link to a video I took with it on my YouTube...

    MM4 77mm

    I did tinker with it a bit on Saturday but haven't formed any conclusions at this point....at least in terms of optics. I will say that it is notably shorter than my 82 mm scope and certainly feels lighter. Despite the lighter feel it still feels very solid considering its compact size. Will...

    MM4 77mm

    I received my demo unit yesterday and will give it a go this weekend. Pics and impressions to follow.

    HR3 zoom eyepiece (41145).

    Steve, I have tried the HR3 but only on the MM3 60 mm (non-ED) that Opticron just introduced this year. I have mounted the HDF on the same scope body and, to be honest, I saw very little difference optically between the two of them. I can try all three when time allows.

    Optics at the ABE

    I did have the opportunity to ask Zeiss about the SF 8x32. The word is Birdfair 2019. I didn't get a chance to check out the Meopta booth. Dennis, Certainly. ;)

    Optics at the ABE

    I will ask the Zeiss and Meoptas guys when I have a chance. Will check on the used models and, yes, a lot of folks buy here because of the show sales. Typically 10% off of MAP.

    Optics at the ABE

    Barry, Yes, no Tract and no Nikon. No surprise on the latter. There hasn’t been a company rep for several years since they restructured and Mike friedberg left. CMBO is the only dealer at the show. It was the same way last year. Not sure of the situation behind that but all sales go through...

    Optics at the ABE

    I was surprised not to see a thread here for the American Birding Expo since it is supposed to be the US equivalent of bird fair. :-) I am here for the 3 day event. Anybody want me to check anything in particular out? More optics companies than I remember seeing in past years....even Steiner...

    HR 80 GA ED with SDL V2 Zoom

    Gander, I have used both scopes and side by side at that. If you are looking for extra reach with higher magnification and better low light performance at the same magnifications (in direct comparison) then the HR 80 ED certainly fits the bill. The HR 80 is sharp right up to its maximum...
