Fotodiox 58mm Macro Reverse Adapter for Mounting Lenses with 58mm Filter Threads on Canon EOS EF/EF-s Cameras

This works exactly as described... you can mount your lens backwards and get extreme magnification from your normal lens. If you want to experiment with this, do a little research ahead of time so you know what to expect and what not to expect. I used my kit 18-55 lens on my Canon Rebel. My first attempt gave me an idea of the strength of the magnification but I didn't love the results. The problem was that I was trying to shoot with the lens wide open and hand held, with the ISO cranked up. This resulted in a depth of field so shallow that it was almost impossible to focus. For the second attempt, I set the lens to f22, didn't try to zoom in as close, and used a table top mini tripod so I could leave my ISO at 100. The exposure time was about 8 seconds with this approach and the results were much better. Pros: Convert a kit lens into a very powerful macro lens. Good fit. My kit lens isn't real heavy, but I never had any fear that it was in danger of falling off the camera due to being mounted backwards. If you have a heavy lens, just keep in mind that you are supporting the weight of the lens by the filter threads. Keep in mind that a shorter focal length gives you more magnification, so if you have a 35 or 50mm prime, you should have a good lens to start experimenting with. Cons: Well, there a lot of them, but I'm more than happy to put up with them, when you look at the cost vs. the results. BTW, this approach was recommended to me by a professional photographer who has several reversing rings for his macro work. So unless you are publishing prints for editorial work, this should be fine for web view or small prints. Here are some things to keep in mind: - You need a very firm setup where neither the camera nor subject is moving. (If you want to photo insects, they'll have to be dead ones.) - The "business" end of the lens is exposed, so you'll want to keep that rear lens cap handy (because now it's a front lens cap). And if you want to leave the lens in this state off the camera, you will need to buy yourself a spare rear lens cap. - The zoom is completely reversed, so 18mm will give you about 3x more magnification than 55mm. - Focus is very sensitive due to the shallow depth of field. Not only that, it's affected by three things: Your zoom setting on the lens (if you are using a zoom), your focus setting on the lens, and the distance between the lens and subject. - The field of view can be dark, blurry, and extremely limited, so it's easy to get "lost" when trying to focus in on your target. I found it helpful to point at the end of my target with my finger (which usually shows up as a big blurry shadow) and then follow that to the end to find where the target is. - With an automatic lens, you will need to first mount the lens in the normal orientation, set the aperture with the camera, then press the DOF preview button on your camera WHILE you remove the lens. This will leave the lens set at the aperture you dialed in (otherwise it reverts back to wide-open when you remove it). For this macro work, you'll need to stop down pretty far. I went with f22 to get a DOF range of about a quarter inch. - When screwing the adapter onto the filter threads of the lens, make sure it is fairly tight, otherwise when you go to remove the lens from the camera, the adapter will start to unscrew. - You have to shoot in manual mode so you can make sure that you have the right exposure. (There's no communication between the lens and camera, so the camera has no idea what the lens aperture is set to.) - Focus is by far the biggest challenge, you need to be able to slightly (and I mean very slightly) nudge the camera or target closer or farther apart in order to fine tune to get the focus you need. You will not be able to use the focus on the lens itself for these adjustments, it's THAT sensitive. You can search the web for focus rails, and some people have made their own. - The quality you get from this approach won't be as good as what you get with a real macro lens. But I didn't have $400 to throw at a macro lens, and I DID have $10 to try this out. For me, it was worth it just to explore this aspect of photography without the huge investment.

It is a passive device. Remember that by default when you use the reversed lens, your lens is wide open giving you a very narrow depth of field. I used this with my MM F/1.4 where the focus is set to infinity. I can get real close (2/3 inches) from the subject and get a full frame shot of a point on your subject. Your lens should be MM filter size. You need to be careful with the following. 1. You are exposing the back of your lens. when you get too close to the subject, make sure you are not knocking anything off with the back element. (hope someone comes up with a back element protection filter {I am planning to make my own}). 2. Most probably you will be moving in and out to get the focus from the subject. If your light source is too close it can cast a glare. (Not sure you can find a lens back side hood) 3. Be careful with the lighting. TTL metering works, but if I experienced some blown out highlights when I was not careful with the lighting. 4. Macros of moving subjects is almost impossible (both to maintain the focus by moving the whole camera with the subject and not to scare away if it is a living object are going to be hard) Check the pictures that I have uploaded. Image description starts with "Gayan's...". If you have time I have the full setup detailed on my site [...] | Reviews section. Enjoy the real cheap macro photo accessory. Please also note that this will not replace a dedicated macro lens. (that will give you distance from the subject, control over f stop (and DoF) and focus).

The ring does exactly what it says it will do. I wanted to try my hand at some cheap macro, and read that this was one way to do it. I use it with an old 28-80mm lens, and it works remarkably well. The ring itself is well made, and has no burrs on the threads to grind in the lens. The bayonet side click in solidly and holds the lens on my T3i nicely. I am glad that I bought this, and plan to use it quite a bit in the next several months to get my feet wet trying some cheap macro, at least until I can buy nicer equipment. Of course, this may work out so well, I don't need to buy new gear.

I had the opportunity to try out some real macro lenses from a professional friend of mine recently, and I found that this ring with a 18-55 KIT LENS reversed vastly *outperformed* my friend's $400 or something 100mm macro EF lens. I imagine that a macro lens is a bit easier to use since you can electronically adjust the aperture and such, but A) Autofocus on a macro is silly and unnecessary most of the time anyway, since the DOF is so tiny you need to artistically choose the focus yourself most of the time. B) You can still set aperture on a reversed lens by putting it on straight, hitting aperture preview on the body, then unmounting it and reversing it. C) most importantly, the $400 lens only magnified up to life size (1:1), whereas I calculated at least 5X magnification (without any noticeable aberrations) using the reversed kit lens (at reversed 18mm)! The stamped date on a penny alone took up almost the entire frame on my T2i. This item is fantastic and is NOT just a "toy" or "beginner's" version of a macro lens. It is better in many respects than the "real thing," and it costs FIFTY times less!! Yes, the sales tax alone on a 100mm EF Macro would cost several times as much as this product, for lesser results. The only reason I can think of for needing a "real" macro lens is if you want to go take pictures of really shy, rare, living insects in the field, that require a longer focal length and speedier aperture, etc. But if you are shooting inanimate objects or dead insects, buy this item instead. BONUS: This also makes a fantastic, strong, metal mount for homemade lenses. I sanded down the outside of a 1.5" PVC plastic pipe, and it fit right into this ring with gorilla glue, allowing me to make a great focusable, rugged, 170mm prime lens for under $20 that I could probably drop off the roof of my house with no problems.

I use this with my Canon Rebel XS and it fits great on the camera but is a little loose when I screw it on my threads. It holds onto the lens okay but I would not trust it. Overall it is a 3 star product not amazing but not terrible. I would not recommend this to a friend or buy again.

PLEASE READ UPDATE AT THE BOTTOM! I have used this $7 ring so many times! As an amateur nature photographer, I have gotten a lot of awesome photos using this lens-reversing ring. I love to use it when I am photographing jumping spiders. Their faces are so cool up close, and this cheap ring is how I get "up close". You screw the ring onto the front of your lens, and mount your lens backwards onto your camera, allowing macro work. I was a little scared when I first tried to screw it on, because I couldn't get it to work right, but now I can have it on my lens and camera in seconds. Note: I have a Canon Rebel T3i and I reverse my 18-55mm lens. If you're using a zoom lens like this, there may be a bit of confusion at first. 18mm is closer than 55mm. So basically, when you mount it backwards, the zoom is backwards too. Most people just use a fixed lens, but I like this, because you can get shots of your subject zoomed in and out. PROS: - Cheap, but very useful! - You don't have to buy an expensive macro lens. CONS: - When the lens is reversed, you can't set the settings like aperture. That means that your depth-of-field may be too shallow, and parts of your subject may be blurred that you don't want to be blurred. - Since I use a zoom lens, at times, the end of the lens that is exposed has an open hole, which allows for debris to enter. This has never really been a problem, but jumping spiders will get curious and jump inside the lens (it has happened several times to me) and this can be a crazy situation. - When I want to use a flash (usually only indoors), all I have is my built-in flash. At certain zooms and focal lengths, the built-in flash will hit the end of the lens instead of the tiny subject. Pretty much the only solution to this is to purchase an external flash that is longer and can be pointed different directions. Those cons are only minor setbacks, but they can get annoying at times. Overall, I love this little accessory, and I don't know what I'd do without it! UPDATE: I often use this macro reverse ring to take close-up pictures of jumping spiders. In the summer of 2012, I captured a picture of a male Habronattus coecatus jumping spider eating a winged insect. I entered this picture in the British Society of Biology's "Feeding Life" photography contest, and I was named Young Photographer of the Year! I am still grateful for this ring!

You can spend hundreds or thousands of dollars in a macro lens, or you can spend less than $10 to turn your current lens into a macro lens. It's a good way to start playing with macro photography without spending a lot of money. This thing is really easy to use: adjust it to your camera, then take your lens reverse it and insert it. Using your lens for macro photography is another deal: as it is reversed, you don't have autofocus, everything is manual. You might also want to get a tripod, as focusing small objects is hard. So, in conclusion, if you're thinking of trying out macro photography, buy this first (if you already own a "normal" lens). I'm guessing that if you'll like it, you'll be buying a good macro lens in a few months....but if you don't like macro photography, your mistake will only cost you a few dollars.

The adapter is of good quality and fits my Canon XSi and 58mm lens perfectly. The lens is very stable and I was able to begin taking very close up shots after just a few minutes of practice. The only downside was in the lens itself. It is the 18-55mm lens that came with the camera and it is not designed to be used in this configuration, so the zooming and focusing are cumbersome. When you try to turn the focus ring the zoom ring wants to turn as well and vice versa since the lens is not anchored at the base.

Strumento comodo pratico, robusto e sicuro, per le mie prove di macro fotografia è l'ideale economico si adatta perfettamente alle mie necessità.

I totally love this ring. I can't believe how well it works. it takes a little fiddling to figure it out at first but it gives macro-type images at a fraction of the cost of a macro lens. What a marvelous invention!

Super product

La verdad dudaba si adquirir el anillo inversor, por cuestion de la montura no me fiaba del todo, pero es un producto muy bueno de buen material se monta perfecto no tiene imperfecciones, es metálico y muy economico para explorar el mundo macro.

very useful and cheap as i wanted... I've done my work great. p.s. becareful for the unlock system. just pull the botton forward.
