58mm - 67mm, 58-67mm Macro Close-up Reverse Ring, Anodized Black Metal Ring, for Nikon, Canon, Sony, Olympus, Pentax, Panasonic, Samsung Camera

Smooth threading. Great for attaching a lens hood to a lens both with female thread.

Took back a $1000 Macro lens from canon, and got better shots from this bad boy. Linked a 85-200mm 15y/o kit lens with extension tube and 40mm pancake reversed, and i'm getting 10x mag. remember, you need a good tripod, F11 on reversed lens, and lost of patience. To set the F-stop to reversed lens, put it on the camera mount, set the F-stop F11 seemed to work for me, and hold the DOF-preview button down while taking the lens off, the iris will hold the same aperture setting. Remember, you don't need autofocus at this macro range, use distance focusing, move closer and further until subject is in focus. Threads are well made, like all Fotodiox accessories. One thing to keep in mind, I got some vignetting at first, but extension tubes helped move the Zoom Lens farther and projecting a larger image on my sensor.

This item works flawless, rigid construction, threads easily into my lenses etc... However the technique to use a reversing ring will cause you much hassle. Trying to use your hands while taking pictures that will be that highly magnified ( two 50mm lenses ) is almost impossible. Setting up a tripod to take your shots well that's kind of annoying but you get results. Trying to get an image with a use able field of view have fun with that. Sure you can get really cool images with this but it will take a lot of work and it's not the rings problem it's the technique. Also be aware you might want to support your lenses hanging a whole lens off the front of another lens that has a plastic focus ring the reversing ring is the strongest part of that whole connection. I took a pictures of "dried flowers" and you could see micro structures but all but 10% of the image was horribly out of focus because of the severely shallow depth of field when using backwards lenses. A better option might be the reversing mount so you can put a single lens onto the body its basically a body cap for your camera with a hole cut in it glued to a filter holder for your lens so you can put a single lens directly onto the body in reverse. You don't get quite the magnification but it's amazingly easier to use.

First things first; If you do not know the utility of a reversing ring, read on: Essentially what this does is allow you to attach a fast prime lens to the front of another lens. This may seems strange at first, but with the right combination of lenses, it becomes a very powerful macro setup. In the case of the 52-67mm reversing ring, this is ideal to mate the Canon 50mm f/1.8 to the Canon 70-200 f/4, and also works well (provided you have the necessary 77-67mm stepping ring) Now, it may look silly to have a lens strapped to the front of another lens, but take a look through the viewfinder. Not much to see, right? Now, move the front of the frankenlens closer and closer to the end of a ball point pen. Now you see what makes this combination useful? That's right. A huge amount of magnification! In fact a 50mm lens has a diopter value of +20, and is generally a multi-element lens, meaning that it will give a sharper picture than those close-up lens sets you can buy at your local camera shop, plus has more magnifying power than you could possibly get with those sets. With a 200mm focal length, the result is 4:1 (Meaning the image projected onto the sensor is 4x the actual size! That said, this ring is just right. It's aluminum, the machining is good, and it works. Not much to be said about it, really. You can't go wrong with it.

Breathing new life into my D3200 + kit lenses: 18-55 / 55-200. Bonus pics of aphids. First two flower pics: Nikkor 35mm 1.8 + Nikon 50mm 1.8 series e. Pic 3/4/5: Nikkor 55-200 + Nikkor 18-55 Coin Pic just to show size reference: Tokina 100mm 2.8. Couple things to note. You can get pretty close with just a reversed prime, such as a 35mm. However, you have to adjust your light source to NOT get what Im assuming is defraction in the middle of the pic. Circular haze. Using this reverse coupling ring presents a different problem. As you can see a good portion of the sensor isnt being utilized. Although to me it seems theres more detail or better resolution. Using a prime reversed with a telephoto seems to solve this problem. Yet the depth of field will be extremely shallow. If youre using "G" lenses, you'll need the macro aperture control adapter. $20. Otherwise, the reversed lens will be stuck at its lowest aperture. You can finagle it with some tape or other DIY creative ways, but for $20, the control adapter is well worth it. Just dont expect the images you see online. Those images, more than likely done with either method, are image stacked at different focal points to give a full depth of field view. Its not impossible to do, just time consuming and tedious. You can use photoshop to achieve this, yet the results or somewhat hit or miss. Theres other software out there dedicated to achieve this effect. While some are paid and others free, ive yet to use them.

Mounting a Canon 50mm 1.8 onto the end of a Canon 70-200mm F4 IS will give you an extreme macro with this adapter ring, however: 1) It vignettes rather badly at 70mm and is still noticible at 200mm. You have to crop about 50% of the image, which is OK if you are interested in a microscopic view. 2) It is very long and difficult to hand hold. A tripod is really helpful. 3) Given the shallow DOF, you must use F16 or higher, which means you need a flash mounted on a bracket and tilted toward the focal point. Since it is a point-blank flash, you also need a mini light-box diffuser to eliminate harsh shadows. Given all of the above, you can take some extreme close-ups of bug eyes and ants heads, but it won't work for product photography or flowers.

Not much to say, besides it works well and fits. Definitely sturdy material. I bought it to use with my Wide Angle Filter with Macro. I needed this to connect the Wide Angle Filter without the Macro to my camera. In short, since the Macro had male threads on both sides (to screw onto the WA Filter and to the Camera threads), I needed this adapter to take the place of the Macro with the Macro effect.

Bad advertisement. As I read through most of the bad comments. Fotodiox is selling it as a "Reverse Macro Ring" which it is not. This is a STEP UP RING to connect a Lens with filter size of 49mm to 52mm filter size. PLEASE UPDATE YOUR DESCRIPTION! DO NOT BUY IF YOU EXPECT THIS TO REVERSE YOUR LENS ON YOUR CAMERA LIKE I DID. If Fotodiox will replace mine with an actual Reverse macro ring then I will change this review as I purchased a different size reverse macro ring from this supplier in the past and it worked great.

Il prodotto si presenta bene, è solido e fa il suo dovere, spedizione veloce!

Cette bague est de bonne conception, mais peut etre un peu trop épaisse... la rigidité est de rigueur, simple et efficace

Supper 👍

Cheep, good quality. Does the job. Used it with Nikon lenses, high quality glas(f2,8)= heavy lenses. The reverse ring was durable
