Solid lens adapter for the price
357074
I'm using this on a Sony Alpha, which accepts Konica Minolta a mount lenses. FYI, the lens thread is 49 millimeters (so it also fits a number of other Sony lenses including the 50 mm f1. 8 lens). This lens is pretty big, about 3 inches in diameter. It lets in a lot of light. Looking at a few test pictures, this add-on lens degrades image detail only marginally (you'd really have to zoom in to notice) and barely reduces brightness. It appears to have a roughly 0.8 x magnification. The " lens cap" is a flimsy plastic cover that slips on ( expect to lose or break this immediately). But it comes with a reasonably nice carrying bag that should serve to provide sufficient protection. Overall, not earth shaking, but certainly worth the price.

I bought this for my Nikkor AF 50mm f/1.8D.
The screw is made of metal while the rest is rubber.

PROS:
It fits pretty well in the lens and it feels solid.
I tested it and it does its job pretty good.
It even helps me find the lens in my bag.

CONS:
The only downside I can find about it is that while it protects the lens and does its job, it covers most of the focus ring, which is already pretty small, so if you are trying to focus manually, it will take some practice and skill.

CONCLUSION:
Overall great quality and built for the price.

Arrived on time. Lens mounts fit, no issues with compatibility. Some of the lenses provide color distortion and issues with focus. On a tripod, it can be impossible to get tack-sharp focus w/some of the filters (not talking about the soft focus, which actually performs as desired!). Understand these are economy lenses. I can overlook a lack of perfection. I think they perform well. Would buy again

This wide angle lens adapter is such an improvement over the "Opteka HD 0.20X Professional AF Fisheye Lens for Canon EO" that I purchased a year ago for use with my T3i w/ 28-55 Kit Lens. The Opteka currently retails on Amazon for Thirty Eight Ninety Five and this one is easily ten times better than it is. For a little over ten dollars, this lens is a real bargain. It has very little color aberration and virtually no blurring of the image, when compared to images taken with my lenses, without any attachments. It still produces vignetting, but all fish-eye adapters do, when the lens it is attached to is 35MM or less. As far as the Macro ring goes, it is meant to be left attached to the adapter, as it converts female 58MM threading to male 58MM. If you are in the market for a fairly lightweight, good quality lens adapter, then this is the bargain you were looking for. I highly recommend this adapter.

I wanted to try a telephoto on my little EOS and this adapter works great.  I've tried it with two different lenses and they both work really well - no problem with the autofocus at all.  It's a solid little thing too.  A good investment for sure.

This was a great deal as a beginner landscape photographer.  Without breaking the bank, I got a whole slew of filters and adapters for almost all of my lenses.  There is a slight color cast, of course, but it's surprisingly tame for what I expected given the price.  If I have any problems with these, it's that they scratch VERY easily and the adapters don't work for very wide shots on large lenses.  Filters always scratch, of course, but these got scratched with just some dust.  It isn't a big deal as my camera focuses right past the scratches.  The adapters work great on most lenses, but on the Tamron 24-70, you can expect very heavy vignetting (you have to buy the correct adapter ring separately - not a problem, just FYI).  Still, for the price, I was happy to get into using ND and ND grad filters.  The colors are kinda hokey and I'd rather have slightly higher quality ND filters for the same cost, but it's not like they can't be fun.  You can't really go wrong by having these in your camera bag.

It is an adapter, what more needs to be said :)  It works just fine with my image stabilized Canon binocs which I use on top of a tripod for astronomy use mainly. You screw the base of the adapter into the through bolt on top of the tripod and the turning bolt on top of the adapter threads into the binocular body.
  Online, many astronomy and camera sites sell similar adapters for $20 to $35, (as in Orion Telescopes) but they are no better than this little adapter. For the $9 I paid, this hits the spot. Five stars.

Hard to find fault with any part of this considering the price point.  Construction and fit seem wonderfully tight and solid, though I'm not sure I'd be OK switching lenses on and off this thing every day.  If that was the case, I'd probably get a dedicated one for each lens and just leave it on there if possible. Images certainly not as optically good as using a Metabones, but it costs 1/20th the price.  Got it for keeping an old Panasonic AF100 going with our Canon lenses as a low end conference/training video camera.

Fits Tokina 11-16 without vignetting. Feels pretty solid but a little brittle. I like the design overall. It's nice to be able to use a filter along with the threaded hood mount. It has ball/spring locks (like how a socket is held on to a ratchet) which was surprising considering the super cheap price. Definitely recommend. My only issue is that I couldn't get the strap to attach to the lens cap. No biggie, I don't like those things anyway.
Buy it, it's great for the price.

I bought this to use my full range of Nikkor lenses (some from the 1970s, some bought last year) with a new Nex 5. After trying all but one, they work perfectly. This adapter isn't the most robust you can buy (those get very expensive), but if you aren't taking it into high mechanical stress situations and you are careful to baby it a bit it should be great. The price is more than right. The locking of the adapter on both lens and camera is very tight out of the box. While this may loosen a little bit over time, who knows, but it's really tight to start. This is fabulous for holding the lens securely and tightly, but means quite a bit of rotational force can be required during the last part of seating and the first part of removing the lens from the adapter. I see this as a good thing, a small price to pay for a very solid connection. There is less force required to remove the adapter from the Nex 5 body.

So the first thing I tried was my dark paper bag test, using my 85mm f1.8 Nikkor to shoot some newspaper copy at the bottom of the bag in available darkness. The photo was much more "lit" than what my eye could see, so the Nex passed wonderfully.

Next I want to mount the camera onto my last Nikkor to try, a 300-600mm zoom. The lens mounts to the tripod, and the camera will hang off of it. The crop factor should make that equivalent to a 450-900mm 35mm-format lens.

Simple, well machined aluminum Micro 4/3 to T-mount adapter.  It easily mated with my 2" telescope adapter, and gives me a solid, stable astro-photography set up.

Works great on my rig.

Not much to comment on, other than I like this design better than the ones that you have to fully slide off. Make sure to click "filter reviews" and search reviews based on the model you're viewing, since several design options for these lens supports are offered under the same page.

Well built, solid and stays in place. Sure beats spending $100 on the Tilta or other options at a more reasonable cost and just as effective in keeping long lenses supported through their entire range. I've uploaded some pics used with my setup and heavy metal SLR Magic lens and heavy Anamorpot 1.33x40 metal anamorphic adaptor.

I have 58mm filters for all my other lenses.  I got this adapter so I didn't need to get another set of filters for my 50mm f1.8.  Adapter works great. Its all metal and threads are smooth.  I have no complains. Shipping was a little slow it took little longer than 2 weeks for me to get it once it was shipped.

This is a pretty awesome adapter and it worked well. If you just need an adapter, without the options to control the lens with your camera functions, then this is a great choice. I got it to mount my lenses to my BMPCC.

Opening could be a little larger, but I would have to say for the price I love the quality, and durability of this little guy. I bought this for a 50mm lens and it did not fit so I used it for an adapter I bought for the Sony a7s AND WAS HAPPY :) Good price, good service, buy it if you need it.

It works as advertised and is thin and unobtrusive. Despite the thinness it feels well-made and durable. The 67mm end screws onto my lens very easily, while the 77mm end requires you to line up the filter pretty accurately to be able to screw it in. Obviously aluminum does have its limitations compared to brass, but at this price point I think this adapter is your best bet.

You could spend less on another name brand adapter, but is you have good filters and lens this is the only way to go.  I handled several of the adapters before purchasing this one.  I use it to mate my&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Canon-EF-70-200mm-f-4-L-IS-USM-Lens-for-Canon-Digital-SLR-Cameras/dp/B000I1X3W8/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Canon EF 70-200mm f/4 L IS USM Lens for Canon Digital SLR Cameras</a>&nbsp;to my&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/B-W-65-073102-77mm-Neutral-Density-0-9-8x-Filter-103/dp/B000RXW0AI/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">B+W 65-073102 77mm Neutral Density 0.9-8x Filter #103</a>, and it works wonderfully and does not require my to spend he $60 to purchase another neutral density in the 67mm size.

Highly recommended.  I now only use B&W filters on all my equipment.
