Plastic or glass lens version? What are the advantages of glass vs. plastic lenses?
776494
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...

It is plastic, but according to Ken Rockwell (kenrockwell dot com ) and his very glowing review of this lens, it is "good" plastic. (That's why it is so reasonable in price) But according to Ken's review, the optics are superior to any other Crop Sensor UWA out there - including the much more expensive 10-22mm from Canon.UPDATE 29 Aug 14: Now that I have had this lens for a couple months, I will say that, while it is plastic, it doesn't feel "cheap." The mount is machine-grade plastic and fits very nicely on my 7D. For the price, this is a heck of a lens.

I think it is plastic but seems to be a good grade of plastic. I have had mine for more than a year and it still looks new. I went back and looked this up and it says GLASS Extra-large 7.5" x 6.25" rectangular glass lens, optical-quality 5-diopter magnification

Hi Leslie. It's not glass, but a very good kind of acrylic or plastic (very clear). The image quality is very good indeed. In my case 3X Magnification is perfect (I tried 2X and 5X and none were the right ones). Additionally the size of the lens is really good (not too big and not too small) The only thing I don't like much is the way it opens. But I can't say anything bad about the image quality. Hope this helps! If any other doubt, just ask :)

I've been using the 14-24mm f2.8 for a year now. Tack sharp! No lens creep. I was worried about no filters to protect glass also. Built in lens hood protects front element well enough. Lens cap fits OVER hood when not in use. I am comfortable with that. No VR doesn't seem to be an issue, as a lot of light comes through the glass and allows higher shutter speeds I feel. I generally shoot with a standard ISO of 400 to kick it up the speed a bit. Great lens. I also use the 24-70mm and 70-200mm lenses, both at f2.8 as well. Throw any pic from these three lenses on you monitor and you could cut yourself on the sharpness. LOL. I've been using the 14-24mm f2.8 for a year now. Tack sharp! No lens creep.

I've had both. They both have the same light gathering abilities, but the version II is smaller and is a bit better optically the the original 14-42, although I think you'd be hard pressed to see the difference in most situations. The version II is a smoother lens, mechanically.

580PC lenses are Polycarbonite lenses. The 580G lenses are Glass and more expensive. Both are great, polarized lenses and the PC is much stronger than a standard plastic lense.

Objective lens is glass the protective lens cap is plastic! The ocular lens. appear to be also glass! Scope is surpriseingly good for the price!

It is PMMA acrylic (trade names include Lucite/Plexiglass). Thickness comes it at 0.0800 inches. It is not as scratch resistant as glass but it is 17x more impact resistant. Acrylic is better than polycarbonate because polycarbonate is not UV resistant. No telling who the lens is made by.

An aspheric lens has less distortions around the edges of the magnifying lens. The mold has more of a concave shape to it to allow for clearer, sharper images.

John, I just checked the camera and I do believe the lens is glass and is protected with plastic. It is a Leica lens.

I do not recommend filters unless it will optically improve an image. If the filter gets broken, it will scratch up and damage the glass on the front of the lens. Lens hoods can protect the front glass to a degree. That's what I use-hoods all the time.

A good lens is always a good or better investment. Lenses will last you across several bodies. Micro adjustment is a feature few people use or need. Yes, it's a "nice to have" but by no means necessary, few lenses require micro adjustment and the process to determine whether a lens needs it or not is fairly involved. Having said that, whining about things like this is red-meat for the Bulletin Board crowd who need things to complain about to make themselves appear knowledgeable. The same with the "Plastic Body." Have you ever seen a cracked camera body? Cameras with plastic bodies have been dropped from airplanes, picked-up, dusted off, and work perfectly. These Carbon Resin (not plastic) bodies are very tough and can take a lot of abuse. Don't get hung up on these little nits, buy a camera that has the features you really want or need and stick within your budget. Even the entry level cameras of today are fantastic image making machines. It's the person behind the camera that usually needs the upgrading.

Both. a Metal Plate screwed into the body of the lens. a Plastic ring protrudes out the center of that plate and engages the camera body. The plastic ring has metal connectors which come out its sides to engage the camera.

I use the plastic one. Costs less works fine. Don't even notice it's on. I use for mostly biking some running.

I don't know what your old lens is, mine was a screw mount. No, there is no glass, it is just a metal ring.

Neither. Mine came in a plastic sack, with the lenses cracked. Horrible packaging.
