Nikon 8x30 EII Objective Diameter in mm?

Has anybody ever measured their objective diameters in mm for the Nikon 8x30 EII. I wanted to order some Opticron tethered objective covers before I get the binocular. If you could measure your's I would appreciate it. Thanks.

I mentioned it on the Swarovski sub-forum
I've been using the tethered objective covers from an Opticron Discovery 8x32. Obvioulsy, they're not made on purpose for the EII, but they happen to work. I'm not sure if they're 42 mm. The truth is that they could be a hair wider, so 43 might well be the number. However, I'm happy with the Discovery's covers.
See pic attached.

Thanks, for the picture. Those look exactly like the 43mm Opticron objective covers I purchased on Amazon.com. I was a little concerned if there was enough lip on the end of the objective of the EII for the tether AND the cap but it looks like they will fit. I find having the tether to keep the caps on preferable to the non-tethered removable caps that come with the EII.

Given the fact that the EII are not sealed, I guess every precaution is needed to try and keep them as dust free as possible, although I'm afraid that the focus mechanism is a likely source of problems in the future, or is it? I live in the countryside (pretty dusty) and it is very humid (I've already have them fogged up) so the durability and state in «old age» is a concern about the EII. I wonder what do other EII owners think about this; what do you reckon?

Like so many things, I think the answer has to be, "It depends..." I have a pair of Carl Zeiss Jena Deltrintem 8x30 binoculars, made in the 1950s (from the serial number). Looking inside them with a bright LED torch (always quite a severe test) reveals that their interior is cleaner than many modern day, sealed binoculars. Granted, I wouldn't want to use those or my EIIs in a dust storm, but I often think that this issue is often overplayed.

Many of us here have (ahem...) a choice of binoculars to pick from when we go out, and if the weather is looking like it's going to be bad, I'll take a sealed pair of binoculars in preference to my EIIs, or if it comes on to rain, the EIIs go back into their padded case sooner. If they do get a little damp, I'll take them out of their case when I get home, dry them off, and leave them out for some hours for everything to dry off. They're such a delightful glass though, I wouldn't want not to have them and enjoy them for fear of their limitations.

I guess it's just about taking reasonable care.

Exactly. In the birding I do 99% I can use my EII. If I was going to the Amazon jungle I would grab a waterproof, sealed roof. I don't think the EII's would be the best choice if you on the beach next to the ocean or in a real humid climate but for most climates and conditions they work fine.

These are the 43mm Opticron objective covers I purchased on Amazon.com installed on the Nikon 8x30 EII. I was a little concerned if there was enough lip on the end of the objective of the EII for the tether AND the cap but they fit perfectly and there is enough lip to hold them on securely even when removing the binoculars from the case. I find having the tether to keep the caps on preferable to the non-tethered removable caps that come with the EII. Here are a few pictures of how they look installed on the EII and an a Nikon 8x30 EII next to a Habicht 10x40 W and a picture of the 54mm Opticron Objective covers installed on the Habicht 10x40. Both objective covers fit very well. I forgot how BIG the FOV is on the EII's. Mine say MIJ clearly printed on them. The EII's are easily the best binocular value under $500.00. The thing is the EII's and the Habicht's are such high quality binoculars compared to the under $1K roofs that it is amazing. You buy an under $1k roof and it is hit or miss on quality. You buy an EII or Habicht and every time every one of them is perfect. No focus slop or drifting diopter's. Everything works perfect. All the older Nikon 8x30 EII's were a little less bright than the Habicht and the contrast wasn't the equal of the newer alpha roofs but Nikon made some significant coating improvements in these newer Nikon 8x30 EII's around the introduction of the Anniversary Edition as reported by Tobias. These newer EII's are much brighter, have better contrast and color rendition with the famous Nikon red bias gone. If you have an older pair of EII's i would say it is worth upgrading. Here is Tobias's thread.

Thanks guys mine arrived yesterday along with the perfect fitting Opticron covers you recommended. Addictive binoculars really. Took some getting used to ergonomically at first I could not hold them acceptably steady but no problem after a day. Against bright setting sunlight today they out-performed my 8x32 SV and 7x42 UV+ which are two of my favorite binoculars. I got an open box model 100th Anniv. at a fair discount. I've never seen the other version but this really looks beautiful. The gray finish looks seriously futuristic. They especially benefit from use with a wide brim hat as their barrels are so short I suppose. Great rainguard and it's the only original accessory I'm using. The OpTech standard bin strap is a great fit. On me it hangs very well. The short barrels make them easier to carry on a strap than a roof of the same weight. I may experiment with using a light harness. Love harnesses.



Can anyone recommend a light mono pod? No way to use a tripod that I can discover. The EIIs stabilized would be luxurious. Thanks in advance for any recommendations.

The Velbon Super 8 is one option, very light, folds very small, good height and robust enough to serve as a walking stick. The folding mechanism is unique, but it is robust enough to have served me well for the past decade. However, this does not have the option to attach little feet and turn into a mini tripod, as do the Sirui and other series.

Your welcome. The EII's have about the widest FOV you can get for the money and they are higher quality than most roofs you are going to find under $500.00. Of course the WX's have a wider FOV but they are $6K!
