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.

It is a prism type lens. A prism system shortens the focal length.http://www.carsonoptical.com/Monoculars_and_Spotters/Monoculars_and_Spotters/CF-718

They are glass, but when I screwed them on they kept popping of the lens, not sure if I just got a bad batch or what. I did like that you can put each one in its separate slot, but was disappointed with the quality. Hope that helps.

Yes there is but I would get a glass one instead of this plastic one. What you look at might not be as clear as a lens made of glass.

They are plastic. In years past I had always had glass in all of my filters, and of course the glass is more durable... and much more expensive than the plastic. After reading several reviews, the reality finally hit me..."How often am I really going to be using these...really?? I decided that it wasn't going to be a great percentage of the time... and when I do, it will be for a specific purpose and series of shots... mostly on a tripod. So the chance of damage is minimized... and I just need to think about what I'm doing... it's not like a skylight or UV where, for the most part, you are leaving it on to protect the lens... ALL of the time. Filter storage is a sturdy fold-over design with hooknloop closure and the filters come in individual clear sleeves that are reuseable if you are careful with them... I have had no problems with the filters getting scratched so far... they are in my kit (3 different diameters to cover my normal lenses and 3 steps ea.) just for the eventuality that I find I am in the situation that I need them... for the price I couldn't beat them. Remember that in the early days of photography, as well as many pro's today, they used gelatin filters ALL the time, not glass.... so yes, they are plastic.

I had two Tamron SP 150-600mm f/5-6.3 Di VC USD lenses, one for Canon and one for Nikon, both came in with plastic case. I enjoyed both lenses with Auto shots.

Yes, I think the lens is glass, although I didn't touch it much to be sure because I didn't want to get fingerprints on it. There were no tools or instructions. I just looked up a video on YouTube that was pretty easy to follow. Hope this helps.

Glass is sharper, and the sharpness is broader in the middle Vs. the plastic one only being very sharp almost completely in the center. The glass lens also has less of the barrel distortion. I'ts simply about preference, typically people purchase the holga cameras for the distortion ability...

I'm not sure what kind of lenses they are, but they seem to be great for glasses, computer screens, phones, etc.

No metal around lens. Bridge is same color as lens. 52 is the size, I believe Rec A is just a style # but not sure.

As far as I can tell, yes, the lens is glass, and not plastic. I have been pleased with this magnifier which I purchased to read hallmarks on sterling silver. It works well both due to the lighted magnification, but also because it is small and thus fits into tight spaces.

I love the Nikon Lens. I've learned that Nikon makes the glass for all of there lenses. The Nikon is a better lens in my opinion and you get what you pay for. You definitly should buy a UV filter to protect all of your lenses.

The lens is not glass. You should be able to very carefully remove the lenses.

The lenses are plastic. They make a huge difference when the original lenses are almost 20 years old.
