I love this adapter! It has been a wonderful way to step in to macro photography without the high price of a dedicated macro lens. It is also so much easier than dealing with extension tubes, because you dont have to unscrew anything from your camera. It just pops on and off. It is also much more compact, so easier to store and travel with. The other day I was taking pictures of dandelions, and my daughter told me she saw a zebra swallowtail, which I had been hoping to get a picture of. If I had extension tubes on my camera, I would have had to unscrew everything, screw a new lens on, and scramble to take the picture. With this, I just popped the adapter off and ran to find the butterfly, which I did, and was very happy. :) I am certain I would have missed out with tubes. Another benefit is that it works with pretty much any camera. I have a Nikon D3100 and was having a difficult time figuring out if the connections with many extention tubes would work with my camera. I dont have to worry about that with this. I still have full function with my camera. I can use it with any and all of my lenses for different macro magnifications. When using with my 55-200mm lens, I found that I can get up to 1.6:1 magnification ratio when fully zoomed at 200mm. Of course, the image looses some clarity at that point, which is the case without the adapter on as well. I have noticed that there is high chromatic aberration with high contrast pictures. This is probably the biggest downfall for me. Sometimes the aberration can be quite noticeable and distracting, and difficult to edit out. However, I do not have any experience with other types of macro equipment, so I cannot compare this to others. The DOF field is EXTREMELY thin, especially when pushing it to its limits. If you want to get a wider DOF you will need to learn focus stacking. But again, I think that is the case with macro in general when you get to this power. All in all, I LOVE it. I have been having so much fun taking pictures of flowers, bugs, coins, other random things. It has opened up a whole new world of stuff to take pictures of, right in my own home and yard. :) I have added some pictures to this review. None of these were cropped to appear larger.
