I purchased this product for use with a telephoto lens accessory for a canon G 10 for the purpose of macro lens photography intra oral photography of teeth, To diminish the amount of reflected flash light either shooting directly or at a mirrored image.I am a dentist

Definitely a good lens, probably use it more than telephoto lenses.

I'm giving this 4 stars - 5 stars for what it does, and 3 stars for the fiddly.I use a Panasonic Lumix G6 MFT camera, and use full-size DSLR lenses with adapters for telephoto along with the occasional adapter that doubles the focal length of the kit lens. Hey, I'm on a budget!The Booster absolutely performs as advertised. When I first got it, I noticed that it was, well, *plasticky* and didn't feel very strong. It came with two adapters for the hot shoe (which I promptly misplaced but found again), and full directions. It took a bit of fiddling with the shoe mounts to get it seated correctly on the camera. I found that the only way to get it to perform properly was with one of the shoe adapters. With an adapter and the Booster in place, miracles happen.Everybody knows that the pop-up flash that every camera comes with is pretty much crap. Well, this little item with the War of the Worlds looking fresnel lens solves a lot of the issues.This will not work with your regular kit lens. This is meant for telephoto distance shooting, and that's how it best performs. Anything shorter than telephoto means that you'll have a blown out white circle in the middle of your picture! Ask me how I know...The pros of this item are pretty simple: It gives your pathetic pop-up enough power to brighten telephoto pics. After the fiddly part is done, it works perfectly. And it's made in the USA. Boom.The cons are simple, too: Plasticky feel, but may be stronger than it seems. It works on telephoto and ONLY on telephoto. Wish that they'd make one for wide angle!So to sum it up, I'm completely happy with the device and like the way it works. I just wish that the fit and finish would give me a little more confidence in its longevity. If it lasts, I will update it to five stars.

I am using this lens for Canon M50 Camera. You will need EOS adapter. I have attached 3 photos taken with this lens.

I recently moved into the category of "serious impassioned amateur photographer" and, after a healthy dose of research, purchased the Canon 20D D-SLR (see my previous review of the camera and experience with it). As is necessary to all impassioned photographers, the lens selection(s) is tantamount to the best photo, as seen by the photographer's inner eye. As a result, when I decided to purchase the 20D, I wanted the broadest breadth of lens exposure possible in the fewest possible lenses.In large part, my search came to a rapid halt when I ran across this lens, the Canon EF 70mm-200mm f/2.8L IS USM Telephoto Zoom lens. While this lens is heavy in terms of weight (approximately 2.9lbs) and price, it is easily the best lens purchase I've made, hands down. I have paired this lens with the Canon EF 24-70mm f/2.8L USM Standard Zoom lens and a 2x telephoto extender, and I am set for most any shoot. I have read reviews regarding quality degradation when shooting with the 2x extender however, I've not experienced that (perhaps it is my inexperience...but my photos don't show it!). The 2x extender has provided me with exposure options from 24mm to 400mm, with the high quality expected from Canon "L" lenses.A few words about IS (image stabilization)...I love to take shots of the moon. First, to get really great shots, one must have a reasonably telephoto lens (that is, if you want to actually see the cheese). The next issue is simply, how do I keep the moon from looking blurry even though the night is totally clear? The answer is simple: get a tripod or get a Canon lens featuring image stabilization. The IS feature has allowed me to take my best moon shots yet, and yes, the cheese is quite visible and quite clear. IS is a must for those shooting without a tripod.All told, this lens is incredibly rich in features, handles well for a large telephoto, has a tripod bracket for easy attachment to a tripod, and is pretty much the nuts for those of us not fully versed in photographic knowledge. While not the most inexpensive lens around, the features and product results afforded by this lens is well worth the cost. I'd buy it again without hesitation.

I got the Vivitar 500mm F/8.0 Multi-Coated Telephoto Lens for my Canon Rebel T6Most powerful one I've ever had.I gave it its first try last night (06/16/22) hand-held just to see if I could get a decent shot of the moon.Dang! I use a tripod and practice some I more think this will work!I am very pleased with it.

Product was securely packaged and fit snugly over both of my Canon telephoto zoom lens. Removal is simple, by a gentle pressure on two tabs.

Love this little extender, it increases my canon 200 telephoto lens to 400 MM. I’ve had no issues with it, it has worked perfectly. I’m really glad I took the plunge and bought it
