Some issues with this...
on July 15, 2015
(2) Stars meaning "It's Okay" ... but what does "okay" mean?
So ... the "okay" things first:
- The optics are as clear and sharp as you can reasonably expect from 25mm lenses at this price. Very good.-
- The diopter adjustment is firm.
- These are quite compact, and fold nearly "barrel-to-barrel."
Now, the "not-so-okay things, and why I returned them:
- Ocular (rear) lens caps = 1. Where was the other? It seems likely that one fell off during packaging, since there was virtually zero tension on the remaining cap. These will fall off, probably when least convenient.
- Objective (front) lens caps = 0. The physical design precludes these, except for a "plug" type. Still, there are none.
- Eye-relief cups/collars. These are a nice idea, executed poorly. They rotate and thread in/out, as opposed to rubber pieces that fold in and out. If you need finely-adjustable eye relief, this might seem like a winner. If you wear glasses and are the primary or sole user, rubber eyepieces stay folded in, and eventually crack, crease, or separate. So these telescoping eye-relief cups seem like a great idea. Well ... no. There is ZERO rotational tension on these --- they will spin at a touch. This means that there is a probability that when you pull them out of the case or a pocket for a quick view you will have NO idea where the eye relief is set, in or out. If this sounds like a petty complaint: rotational tension on any optical control is a must.
- Back to that eyepiece diopter ring --- it sits just ahead of the free-spinning eye-relief cup. You can see the issue, there...
Bottom line: I was disappointed.
- These are not very expensive, but they are not cheap, and they do bear the Nikon logo. That brand is valued for its lenses and build quality, so it's ironic that the "front" lenses will never be protected, and the "rear" lenses will be protected only as long as you can find the cap(s) that fell off.
- Free-spinning telescoping eye-relief cups are a no-go, at least for me.
If you like clear, sharp images with unprotected lenses and roll-the-dice eye relief that will probably change with diopter settings, you might like these. I did not.
