Finally pulled trigger on new, still unreviewed, TS 23x100 ED binoculars.

Its on the way to me today, and hope to get it soon.

 

Here is link of it, but I think they are not originally green....

Hey, good job!

 

PS. How are you planning to mount/use these? I hope you have strong arms :)

Hello Denis,

 

I have also my eyes on these, and especially, if the objectives are ED.

 

Looking forward to your report,

Don't see focal length or f ratio listed.....:question:

The other KUO 28x110mm binos run about 530mm or f4.8 with 19mm 66° eyepieces.  However, to reach a 2.9° FOV with a 66° AFOV at 23x and keep the field stop to no more than the usual 22mm to match up with the prisms, it would need to be f4.  At f4.8, it would need 23mm eyepieces with a large 26.5mm FS.  I doubt that's what's happening.  Something has to give; the objective has to be faster, the prisms larger or the FOV/AFOV smaller.  No length dimension given on the TS site to compare with the original 28x110.     question.gif

It's going to be faster than f/5 otherwise the focal length wouldn't fit into the 540mm physical length.

Yeah, for sure. But you have to take the folded prism path into account, too.  I missed the 540mm length; the 28x110 APM is listed as being 530mm in length.  I wonder about those dimensions.   The width dimension given between TS and APM are even further different too; 275mm vs 240mm.  Hmm.

 

Just the same, something is very different between the two 110mm binos if the specs are stated correctly. The focal length must be shorter than the 28x110s for the math to work out for me.

I have universal custom made short adapter for Manfrotto fluid head and tripod.....I already used 20x100 and 28x110 binoculars on it without any problem.

23x110 model should be shorter than 20x110 and 28x110, based ony my research of pictures, and also lower in weight.

Yes, I am also wondering how good picture quality is, and wondering if these really are ED objectives, or performance, if its very good, is matches by eyepieces complexity and prisms system......

Hi Dennis,

 

great news, can’t wait to hear your impressions. 

 

Unfortunately, there’s another version still unrewiewed, 34x110 (no ED), running around in eBay and AliExpress, and also the ‘Mark II’ version of the 28x110, in the APM site, with new body/dimmensions at least.
 

I had once the original 28x110, it was an impressive instrument, but one of the objectives was optically very bad and I returned it eventually.

...just did research for 34x110: I see it have smaller eye releaf than 28x110, and when I had 28x110, it was tottaly uncomfortable for my taste, so 34x110........undecided.gif

Denis, have you tried the APM MS ED 25x100?  It would be interesting to compare the two.  The focal length of it is listed as 372mm so if correct, it only needs 15mm 67.5° eyepieces (17.7mm FS). Not pushing the prism aperture at all.  It's quite conceivable that a 23x110ED could be f4 if that is the case.

 

I look forward to your observations.

Somewhat never wanted to get 25x100 ED....but 110mm ED objectives ARE interested for me nowdays.

The eyepieces in the APM 100mm binoculars have possibly the 6 lenses design, like in the Argus,

https://www.optik-pr...ab_bar_2_select

and that's something I don't particularly like when it comes from .....

 

What I am after, are the big binos with low magnification, long eye relief and minimum glass inside.

I am not going to watch the Cassini division or to split the Double Double Epsilon Lyrae with the binoculars, ha, ha.

 

Best,

JG

I had Argus 25x100.
Very nice indeed.
I just wish they had thinner eyepieces-they arw very fat, and to see whole FOV, I had to press hard my bones and skin from eyes and nose, to see whole FOV.

Hope its not same with new TS 23x110 ED.

I really enjoy in comfort!

I also would like to know if these are true ED.

I would say it is not possible at this price...

 

Comparing them to the APM 25x100ED really would be great, also to see if the eyepieces are similar wide angle, what was not the case with the old, non ED, 110mm glasses.

Jochen, ED is easy, that's just a matter of the glass used.
It is true APO that is hard. Frankly, I don't think you should expect this in binoculars.

There is no ED text on binoculars.....

Eyepieces looks just like I like: large lens diameter!!!
