Hello; I have a friend that has a narrow IPD of 52 mm and I was looking for info on bins that might go that narrow an IPD. Seems to me a lot of the old small zeiss framed binos of the 50's through the 80's would all go to 50mm or so and was wondering if the 8x30 eII would fall into that category. Thanks, Pat

Gijs van Ginkel; Thanks for the info, a bit too wide for the gents IPD. I was hoping that one of the few remaining quality porros would go to the low50's in IPD. Too bad. Looks like the most likely group of binocs that would have the narrow IPD are the twin pivot compact roofs (despite that not being the class of glass he was looking for). I appreciate the prompt response. Regards, Pat

Just measured 52.5 mm for my 8x30 EII. Nikon 8x30 E measured 48.5 mm. The narrowest IPD among my binoculars is the Swarovski 8x30 Habicht at 47 mm.

6x24 Bin 2 Made in USSR 1977 multicoated 12.2 degrees field.

Minimum IPD is 41.5mm.

However, if one has a nose then 50mm or 51mm may be needed.
Also not for glasses wearers.

Bausch and Lomb 7x35 Discoverer 50.0mm minimum IPD. Thin eyepieces. Probably enough eye relief for thin glasses. 7.5 degrees.

Nikon EII 8x30 52.5mm minimum IPD. 8.85 degrees, but I don't know about nose or glasses.

Swift 8.5x44 HR/5 ~55.0mm minimum IPD. 8.26 degrees.

All Porros.

Regards,
B.

We measured 56-72 mm IPD for the Nikon EII 8x30 and in the specifications of the EII supplied by Nikon we find the same values.

Hi Gijs,

A quick measure of my 8x30's: the Nikon EII and E, and the Swarovski Habicht
- all show the same minimum IPD's as those recorded by Henry

In contrast, looking at the specification sheets for both the Nikons and the Habicht, all show an official minimum of 56 mm!

My 8x30 EII measures 52.5mm minimum IPD.

However, the size of eyepieces and eye relief are important to make room for a nose.

Yes that is what I also noticed and the interesting question now arises: if Swarovski gives a 3.3 meter close focus value for the new NL binoculars, how much closer will it be in reality???????????????

I've noticed that IPD specs are often wrong, usually understated.

Binastro makes a good point about nose clearance. At its lowest IPD setting of 52.5 mm the EII nose clearance is 8.5mm. The E with smaller eyepieces has 11 mm of nose clearance with its IPD set at 48.5 mm. The Habicht with the smallest eyepieces has nose clearance of 11mm with its IPD set at 47 mm.

Hello,
I have my eyes close together and in photographs I have seen that this binocular has large eyecups (larger, for example, than the Swarovski Habicht 8X30), in addition to a large nose (although not a Cirano nose), I am thinking of acquiring it but This makes me think ...

a greeting,
Pluto.

Not so sure it need be a problem for a Cirano nose; maybe more so for a Rocky Marciano?

I suppose one could copy Tycho Brahe if one really wanted a Nikon EII but was struggling to fit it.

His nose was found to be brass, with silver or gold for special occasions.
He shouldn't have argued with his cousin as to which one was the better mathematician.
And he shouldn't have got drunk.
