EDG pin spanner

I've found that that a 1.5mm "pin-type face spanner" such as one supplied by J. W. Winco < www.jwwinco.com > works really well on the EDG hinge; because of the right-angle face-spanner design, one...

Hi Ludwig, welcome!

If you could find a pair of Leitz replacement rubber eyecups made for the first Trinovid models (the original series, with the Uppendahl prisms), you'll find that the threads...

I agree! I have access to early and late examples of the 8.5x42 - a 2003 EL WB (upgraded by SONA), and a 2015 SV, and I slightly prefer the view through the older one. Both are superb instruments,...

I've owned several EDGs, Type I and II, and I've never had a problem with the diopter control slipping or "wandering". They do have an eye relief distance that's a bit too long for my eyeglasses and...

I just looked inside my 7x42 Dialyt (2395xxx) and it's clean: no haze, no cloudiness that I can see anywhere.

I think they're very good, relative to the state of the art at the time. My example is 709xxx and it's not quite as good as a Leitz Binuxit, but it's very nice. Focus direction is ccw to infinity,...

My experience was the opposite of what Pileatus found, namely that 1) the 12x view was more satisfying to me than the 10x, 2) there was no difference in brightness between the two as long as ambient...

The Uppendahl prisms I have looked at have only one mirrored surface, the first (upper, sloping) reflective surface in the bottom prism; all other reflections are TIR.

Richard,

My thoughts are: 1) your 10x42 L unfortunately is defective, and 2) your supplier is defective as well. I recommend replacing both.

The focus action on my 10x42 L is smooth as silk, by...

Having owned all three, I feel I can say that the 7x45 is every bit as good as the 7x42 B/GAT but larger and heavier, and the lighter and more compact FL is a worthy successor to both of them.

Hi Dorian,

The Zeiss 7x42 B/GAT focuses CW to infinity (from the user's perspective). A wonderful bino and an old friend; I still have mine and use it now and then.

I just bought a new 10x42 Razor HD, at a discount, and both the box and the binos are marked "Made in Japan". Do you suppose I can believe it? Very nice binos, nonetheless.

Hi Adhoc,

Not wanting to take anything away from the excellent Conquest, in my experience the FL controls lateral CA better and its transmission figure is higher.

In my opinion the Zeiss FL 10x32 will run circles around the other two. It gives a very wide (6.9*) and very bright field of view, it's very compact and has an excellent (though somewhat...

Sorry, when you said "Zeiss Dialyt 8x30 B/GA T*" I thought you were referring to the CF Dialyt model (sometimes called "Classic"). My mistake.

I think Zeiss already did that, with the 7x45 T*P* Night Owl / Design Selection. It's a very fine bino - wide field, bright, sharp.
