    What case are the Leica 8x42 Trinovid HD owners using?

    Just got the 8x42 Trinovid HD bins and love them. However, that brown upside down case sucks. Seems that they want you to thread the straps thru the back of the case and use them like that with it in the way imo. I’d really like to have a neoprene case that opens from the top so I can carry...

    Wow - what a surprise set of bins

    I recently decided to purge some of my toys and sold my Zeiss Victory 8x32 T* FL for more than I paid for them 8 years ago. Feeling remorse, I just received a pair of like new Leica 8x42 Trinovid HD yesterday at a bargain price. At the same time, I received a Cabelas Intensity HD 8x42 for the...

    Who do I believe - Leica Trinovid HD versus Zeiss Conquest HD

    I’ve narrowed my choice down to these two. One online review had 6 (non-expert) testers and they chose the Zeiss. A birding review rated the Leica a bit higher. The Zeiss does have the T* coatings but I have the Leica Ultravid 8x20 so I’m familiar with their quality as well. Just trying to...

    Any reviews on the Vanguard Endeavor Ed II Binoculars - 8x32mm

    I’ve been away from the site for a while and it looks different from what I recall. Was there any threads on this binocular? Thanks.

    How would you repair these 8x20 Leica Ultravids?

    I was looking at my 8x20 Ultravids and noticed the front cover looked warped and was loose at the top. I was able to peel it off real easy (looks like it had been glued on with an elastic rubber type adhesive). I cleaned it off and used some Fletchtite glue use to attach feathers to arrows...

    What bird did I see today?

    I'm in SE Michigan and looking out the front picture window, I thought I saw 2 starlings in the front yard - but they looked different. I had my binos so I got a closer look and they a bit "chubby" with a long yellow beak,]. And although with a dark body color there was a greenish tint in the...

    Question about exit pupil and brightness

    If I compare the same manf/model of a 10x40 bin to an 8x32 bin, would the 40mm seemed brighter or would they have identical brightness due to having the same 4mm exit pupil? Thanks.

    List of definitions of optical terms for dummies?

    Just wondering if there's a list of optical term definitions that is easy to understand. I can look up CA and flare but some of the descriptions don't seem to be very understandable to a novice. Is there a list available that's understandable and easy to understand? Thanks.

    Is FOV linked to brightness?

    Forgive me for asking on a binocular sub forum but I can always count on getting the correct answer here on optics questions. I understand exit pupil and lens coatings that allow light transfer, but let's take two variable power rifle scopes for example. Scope A is a 2.5-10x40 and on 5x has an...

    How do I separate light transfer vs exit pupil?

    I understand better coatings promote more light transfer in optics and I understand exit pupil. Let's take a 2-8x32 variable power rifle scope that the manufacture specifies their coatings allow 94% light transmission. On 2x, there would be an exit pupil of 16mm - can I assume the coatings...

    My 8x32 Blue Sky failed but all is not lost.

    I was at the Michigan game on Sept 20th in the rain with my Sightrons, didn't think anything of it. Went to look thru them the next Saturday and the left objective was clouded over, looked like dried milk was spilled on the inside. Called Sightron and they said to send them in. They have never...

    Newbie question about digiscoping

    I was playing with my iPhone 5S with my spotting scope last night and when I got it centered and at a specific distance, I got a really nice photo. But as I look at the adapters for binoculars online, they don't appear to be able to hold the iPhone far enough away as required with my spotter...

    Sightron Blue Sky 8x32 never ceases to amaze . . .

    Last week I had my Zeiss T* FL 8x32 bins at the night time Michigan - Notre Game game, man they were awesome to look thru. But taking them to the games makes me nervous so today I took my Sightron Blue Sky 8x32 bins - these dang things have to be one of the best low priced bargains there is. I...

    Got to test my Victory T* FL 8x32 bins Saturday

    For the last couple of years I've been using my Gold Ring 8x32 bins at the Michigan football games but they always felt like I was carrying a couple of bricks. I sold them earlier this year and picked up a new pair of Victory 8x32 bins at a pretty good deal. I had them yesterday at the game and...

    Got a response from Zeiss about the prisms in the 8x32 T* FL versus the 8x42

    While contemplating selling my 8x42 bins and just keeping the 8x32, I sent an inquiry to Zeiss about the different prisms used between the two. Here is their response: **************************************************************** Thank you for your inquiry to ZEISS. Yes, that is right...

    What would you do with this dilemma?

    I had the post earlier about the low light differences between my 8x42 and 8x32 Zeiss Victory bins - where I couldn't tell any differences in the dark. This morning I went back out a bit earlier and when looking at the tree line 315 yards away - I couldn't see any difference. But, when looking...

    Question about a 4.0 versus 5.25 exit pupil

    I have a Zeiss Victory T* FL 8x42 and looking thru them in low light is unbelievable. I picked up the same bin in an 8x32 earlier this year and they are just as nice (duh). This morning I was out after coyotes and had both bins with me. In low light, I couldn't tell any difference in the...

    Zeiss Victory T* FL 8x32 bins came today - OMG

    My 8x32 bins came today and they are awesome - eye relief is not an issue with my glasses. I have the same exact bins in 8x42 so I knew what I was getting but the compactness of these gems is really sweet. I see why those that own them, love them. I sure do.

    Is there a "Digiscoping for Dummies" thread?

    I'd like to try digiscoping but the few times I've tried it seems I might not be getting the camera distance from the scope lens correct. Plus advice on camera setting at low power/high power, distance setting at close-regular-far, etc. Thanks.

    Zeiss Victory T* FL 8x32 eye relief question

    I have a pair of Zeiss Victory 8x42 bins and the advertised eye relief is only 16mm but it is plenty for me as an eye glass wearer. I'd like to get a pair of Victory T* FL 8x32 bins with the same advertised 16mm eye relief. I had to sell my 8x32 Els because their 15.5mm stingy eye relief was a...

    Leupold GR 8x32 - HD versus non-HD

    What difference would someone see between a non-HD Gold Ring versus an HD Gold Ring. I have the non-HD model and when I compare them to my Zeiss 8x42 Victory and the clarity of my 8x32 Leicas, these dang non-HD Gold Rings can hold their own pretty well. Thanks.

    Low light - bins versus rifle scope

    I was out this morning for the last day of regular firearms season. While sitting in the middle of a picked field well before daylight, I looked at a spot along the woods about 100 yards away with my Zeiss Victory 8x42 bins. I could see pretty much everything along the woodline. Then I picked up...

    Question about useable exit pupil

    Years ago one of the favorite bin used by outfitters in the western states was the Swarovski 8x56 SL for their low light capability. These had a 7mm exit pupil. It is said that as we age, our ability to use this exit pupil is reduced. So as I get on into my 60's, I assume that I would see no...

    My Sightron Blue Sky 8x32 came today - my thoughts

    My Sigtron II Blue Sky 8x32 bins came today and my overall thoughts are - impressive. You see in my signature of my current bins and I've owned (3) Swarovski bins in the past. My biggest concern was the focus wheel and this one is smooth as butter -no hesitation, no slop or freeplay. I even put...

    Thoughts on the Vortex Diamondback 7x36

    In case my Sightron Blue Sky 8x32 bins don't work out, I'm curious about the Vortex Diamondback 7x36 bins. These would have an exit pupil of a tad over 5mm. I think these have been discontinued but I was wondering if they were a decent bin for the money or just an average <$200 bin? Thanks.
