Is the lens housing made of plastic material, and how about the lens element, are these made of plastic too? Why is all the sample image uploaded to internet has unanimous plastic look, as if whole world is made out of plastic?

These are top-quality lens you would expect from Nikon. You should read the specs rather than try to deduce specs from pictures.

The frame is a powder coated metal, I did a scratch test. The weight of each lens indicates they are glass, no I did not do a scratch test on the lens. I have found them extremely useful and I use an extension tube to protect my camera lens. The close-lens mounts to the end of the extension tude and does not travel with the lens itself. I have no problem using one lens at a time, but had a problem with distortion when I used the +4 and +10 together, The distortion would probably not happen if they were attached directly to your main lens.

Only the lenses are glass! All else is very hard palmer type plastic. I think it is a pretty good night scope for the price. You get what you pay for when it comes to night scopes. Don't buy it and expect perfection.

Vivitar states they are HIGH QUALITY SOLID OPTICAL MATERIALS. The CPL feels [weight] like glass. The other two are much lighter and not so cool to the touch. I think they are made from the solid optical material.I can't see any anomalies or aberrations in either the filters themselves nor, the images I've taken with them on my lenses.I put filters on my lens mainly to prevent scratches and damage to the glass lens and its coating. I'd much rather remove dirt, grit, and smudges from my filters than my lens. After that primary usage is accomplished, then, for the type filter: UV, CPL, or, Neutral Density.Hope this helps.

I ordered this lens for my daughter for Christmas and it is new in original packaging. The 'additional' components to the package deal (like the filters, lens cloth, etc.) were in the Amazon package itself - not in with the lens. Hope this is helpful.

I'm not sure of what your question is about ,the housing is weather proof rain drops could spot the outside of the plastic lens. May have a problem if you live where the temps get very cold with pan and focus.

I assume you are talking about the two small lenses shown in the picture. They are very cheap Vivitar lenses. One is macro and the other is wide angle, both are garbage. The rest of the bundle is fairly decent though.

Hi Katie: The scope is made of metal, has protective plastic caps for front and rear lenses. I think I paid about the same price for a simular scope about 15 years ago, which I accidendly bumped really hard and ruined it, I feel it's a great scope for the price and for my needs, I have it mounted on my 22 LR. Remminton Semi automatic rifle. with some slight lense adjustments it was ready to go. Joe.

The Black and clear part of the loupe are plastic. The lenses are glass. It works really well.

Body is metal and the lens are plastic. They are so far working well after several months.

The only plastic is the lens cover and the part that is around the lens. There is a plastic knob right above the lens. I find it very sturdy other than the lens cover which I took of in the first 5 minutes that I used it because it had nothing to hold it open and just flapped around. No biggy to me.

The frame feels and looks like powder-coated aluminum. As to whether the lens is glass or plastic, I can't tell.

My son really likes this microscope. I am not positive but it looks like the Base and body are plastic and the rest is metal. The parts that hold the lenses are definitely metal. Hope this helps. It works great

alas, I'm not sure. as Vivitar's photo shows, they're black plastic on the outside. they feel pretty rigid, but I don';t know if they'll be good enough with a heavy lens on them. on the other hand, my ball head is'nt steady enough for the 30mm tube. Kenko's tubes have the same appearance (metal or plastic) but theirs, altho more expensive, do make contact between the camera and lens, and do engage the safety snap that holds your lens on the camera.

The lens is actually a polycarbonate which is a optical quality material and virtually unbreakable. It is actually a lighter and more expensive material than glass.

I wouldn't worry too much about this. The lense cap for the objective lenses (the large ones away from the viewer) are fine and made from a nice rubber material. The cover for the eyepieces are a bit cheaply made and in fact the connecting piece on my first pair broke after 2-3 years. I just got another one from a friend. The quality of the optics in my opinion totally makes this a minor problem

Sorry, I can't help with that. Perhaps you should contact the seller. I found them very helpful. I can say the case is sturdy, and the threads are metal. I would worry more about losing or damaging the lenses rather than the case.
