Summary: The Vivitar 500MR lens Mirror Telephoto Lens was well made but after hours of testing and hundresd of photo's on a Nikon D70S and a New Nikon D3200, on tripod and with remote shutter release I could not get a decent photo no matter what settings I used, I really hated that it would not take a decent photo as I use my 300 MM nikon VR lens a lot and need a little more distance.
Impossible to focus even at a quarter million miles

Summary: I made a mistake and tried to buy a very long lens, very cheaply. The lens really doesn't cost anything and that is exactly what you get. The lens I received simply CAN NOT be focused. I realize that at 100 yards, it only has a focal zone of 32 feet but last night I was trying to focus on the moon~250,000 miles away. No focus at any point, certainly not at infinity. My set up was a high quality tripod with an additional 20 pounds of lead weight for stability.
Summary: I purchased this used, however, if I didn't know it was "used", I would've thought it was new. A much better product than the older f/6.3 version due mainly to the smaller size. Photos are sharp with very little of any aberrations. The mount is a bit wobbly, however, I've come to expect that from t-mount lenses. That did not effect the sharpness at all. If you can find one of these in the seventy to eighty dollar price range, just buy it.
Summary: I've only spent an hour or so testing this lens, but so far I'm quite happy with it. But be realistic, this is NOT an "L" class lens, nor is it "fast glass"! For $100 (in round numbers), however, it is fairly decent. First, be sure to order an adapter that fits YOUR camera to go with it. For my Canon T3i, I got a fotodiox product, which has worked fine.
Summary: For each job you need a speicif lens. This lens like others, has limitations and is good for only certain things. Same as the other lenses you will have for your camera. Now do not expect a lens that runs $110 to give the results of a $2000 lens simply because it can magnify to 500mm. I have read mixed reviews of the lens, decided to get one and give it a try. Photos are from a Canon T2i, ISO 800, shutter 60. Taken at night.
Summary: The 500mm is on Amazon for a bunch of different cameras, I think they are the same lens with a different ring mount. This lens is great for shooting shots across the waterways and at the zoo. With an f/8.0, it works best on a bright sunny day. Use of a tripod helps get sharp pictures. Simply put... I use it more for wildlife & that hard to get close shot when someone or something is in your way, very inexpensive easy to use once ya get used to it, can't complain.
Summary: Solid quality construction. Sturdy, yet lightweight, and doesn't have the least "dinky" feel to it. Very smooth focus ring with just the right amount of resistance. This f/8.0 version is, with its 72mm diameter, very portable and quite a bit smaller than the f/6.3 variant with its 92mm diameter.
