Nikon FE eyepice/finder

[Montanawildlives]

I'm a little confused about the terminology for the various parts of the eyepiece system. I just bought a Nikon FE that does not have the rubber bit on the end of the eyepiece (potentially scratching my glasses). But the piece that IS there appears to be fixed (not unscrewable) but with threads on the inside, and as it is the system works (other than scratching my glasses) so I don't think I am necessarily MISSING some vital element.

But, what I think I need/want is the little screw in attachment, without glass, just to provide a softer cover and perhaps a millimeter or two of relief. Is this the "2925" piece that sells for $21.95 at Adorama (!)?

And what is the 2925 piece called? The eyepiece? The eyepiece finder (Adorama calls it the latter, other places it is just "eyepiece")?

Then there are the diopter versions--I don't think I need one at this point but are these used IN PLACE of the 2925, or attached to it? Between the 2925 and the fixed portion of this system?

Thanks!

(p.s., I am not terribly interested in the eye cup piece (to provide protection from light when looking through the eyepiece/finder, but...if I want one later, will this screw into the 2925? Ug.

Usually it's just referred to as "eyepiece", don't know why Adorma adds "finder". If your camera doesn't have the round piece that unscrews, then it's missing the "eyepiece" and the Adorama item (or the same from other vendors) is what you need. The diopter versions are used in place of the standard one.

Sometimes the eyecup simply stretches over the eyepiece, sometimes it is threaded and the eyepiece threads into it. I'm pretty sure Nikon has done it both ways for different cameras. As a fellow eyeglass wearer, I've not found eyecups to be that useful, but YMMV.

Thanks bdial. I should have included a picture....this is what mine looks like--does it appear that I am missing a vital component? I tried to unscrew what is there and it would not budge...either it is a fixed piece of the camera or it i

s well stuck.

Thanks!

I think that is the threads that the eyepiece screws into:

here is the part:

(the adorama photo isn't very helpful, but it is probably the same piece.)

Thanks everyone. So, I clearly need something there. Now, I'm second guessing myself about the diopter. When I look through the eyepiece it seems sharp.....enough. When I pull my head back an inch, it is sharper.

I usually wear contacts and reading/computer glasses, but the strength of the reading/computer glasses varies as a function of the distance to the object (computer 3 feet away versus book 1 food away). So, how do I know what strength diopter to get/try or even if I need one?!?

 

[abruzzi]

I have never really needed diopters, but my F4 has an adjuster. So when I was dialing it in, I found that looking at the lines etched on the focusing screen is how you want to determine if the diopter is correct (blur the focus of the lens so the image doesn't distract you). As far as determining what you need, trying them is the only solution I know. You may be able to go to an eyeglass place. The should have a bunch of diopters that they use to determine bifocal strength. I don't know if pressing them up to the viewfinder of your camera will be accurate, but that might work.

If you can see fine through the finder without a diopter you don't need a diopter, just get a zero eyepiece. And until you get one you can put a bit of tape on the threaded bit to protect your glasses.

Take your camera to the dollar store and try looking at the screen texture through a few different reading glasses. The one that works the best will tell you which diopter you need (if any).
The real challenge will be determining if the diopter numbering system used by Nikon includes an offset - i.e. if the system with a "standard" eyepiece is already something like a +1 diopter.

This doesn't work for me at least, probably because the intended viewing distances for the diopter values are different: two feet for reading glasses, one meter for the camera.

This eyepiece is identical for FA/FM/FM2/F3a/FE/FE2

I've even seen Chinese knockoffs on Ebay.

Technically speaking an eyepiece is the complete optical shebang behind the prism.
