Summary: Likes: -The adapter is made of a solid metal construction and feels high quality in the hand. -Macro lens is great in quality of photos and build. -The Wide Angle portion (macro+front glass element) is pretty good for the price point. -The adapter has a front 82mm filter thread. Dislikes: -The front lens element was loose, however it was an easy fix simply by turning the element to the right locking it in place.
Summary: I have a 20mm lens and I thought I could add this to it and get a cheapo 9mm lens, because 20mm * .45 equals about 9... Because I wanted to get even wider than my 14mm could go, on a particular subject. When you crop out the vignetting this lens produces, however, it seems at most to take the 20mm down to about 16mm. I do have a full-frame DSLR and this may be the problem. Also, it's possible that the macro feature will be of some use.
Summary: I've had this lens add-on for about 3 years now. I use it on and off, depending upon the mood and circumstances, like nearly everything else in my kit bag. This lens is a 2 part add-on. the wider, front element is the wide-angle lens and the rear element is the macro lens. The lens elements must be used together to get the wide angle you strive for when you attach this add-on to your primary lens.
Summary: For the price it is not bad. But if you expect good "wide angle" forget it. If you expect perfect "macro" forget it. But if you are a novice (like me) this was not a waste of money. Top end lenses are out of my reach at the moment. The Wide Angle must be used with the Macro.
Summary: The wide angle lens really isn't bad but IT CANNOT BE USED WITHOUT THE MACRO LENS ATTACHED. I was hoping to use the wide angle adapter alone because the less glass I'm adding to the front of my own lens the better, but the diameter of the wide angle adapter is not 72mm and will not fit on my SONY HVR-Z5U lens without the macro lens attached. The macro lens can be used alone.
Summary: It works great if you know what your doing. I'm using this with an EF 28-135 and I'm not noticing much vignetting even zoomed. This thing is solid metal and heavy. It will make a zoom lens creep if it's vertical. Gravity Zoom?
Summary: Don't buy this lens. Now with that out of the way, buy this lens IF you know it's not a great wide angle lens, it's not a great macro lens, there's a ton of vignetting, even fully wide mine has vignetting all around. I have it on my Nikkor 18-200, zoomed in is almost useless. NOW. With that in mind, it's a great lens FOR vignetting, soft focus, an almost tilt-shift like quality depending on your zoom factor.
