Gotta love Amazon!! The order was received in 2 days with free shipping (I'm a Prime member)...and the product is exactly what I wanted. It takes the 18-55mm kit lens for my daughter's Canon T3i (which is equivalent to a 27mm film lens) and makes it basically a 10mm lens, ideal for any occasion where a wider angle lens is needed. A friend of mine owns a Nikon 12mm lens he paid $2,500 for. It's really nice. But I paid 100 times less, and the results from mine are really nice too!Why did I buy it?I do real estate marketing for a living (design and printwork) and I bought my daughter the Canon for Christmas. She's got a great eye for photography, and I wanted to introduce her to real estate photography. Well, she had her first photo shoot last Saturday, and the photos came out really well. However, I could tell that the images we took, weren't as wide of an angle as those taken by professional real estate photographers. So...I asked one of my favorite photographers about his equipment (he's the one with the $2,500 Nikon lens). He told me what my options were, and I searched on Amazon for what I thought would be a good fit.This lens obviously caught my attention because it gives me the same focal length for a ridiculously low price (actually a little wider than his Nikon). When we first got it, I couldn't wait to try it out. So we opened the box, saw the leather pouch it comes in, took it out and screwed it onto the Canon. When I turned the LCD viewfinder on, I almost couldn't believe it! It's not quite 180 degrees....but if you stand in the doorway of a small bedroom, let's say, you'll absolutely have every part of the room showing in your lens. Amazing! It also captures much more of the "floor-to-ceiling" so it expands things both horizontally and vertically.I wish we had purchased it prior to last Saturday's shoot, as I think the photos we took would have been much better (even though they were already good!) I'm almost thinking about driving back out to the property as a favor to my customer and re-shooting the house. The wider angles work really well for real estate photography...and it would've given all of the images a much more professional look and feel.If there's any caution with the lens...it's this. At it's widest angle, you will definitely get vignetting (the corners turn black)...however that happens with basically ALL wide angle lenses (most especially with fisheye lenses). I just back off the widest setting slightly, and the black corners went away. Still though, you'll need software to help correct for the lens distortion where things curve around the edges (in other words, the left and right walls will be curved when shooting a room). GIMP does a pretty decent job of that with its lens distortion filter, and their software is free.All in all, I couldn't be more pleased with this lens! I haven't used the macro aspect of the lens yet, as it was purchased primarily for the wider angle requirements....but I'm fairly certain the macro will be great too! The lens feels very high quality (heavy, and doesn't feel cheap at all.) It screwed onto the camera with no effort at all (but as with photo filters, the threads are VERY fine so you have to make sure you've got it on correctly before tightening down. You don't want to strip the threads.) Mine went on perfectly, and smoothly.Oh, one more thing I noticed. If you use the built-in flash on the camera (it's forward facing)...you'll get a small "half-circle" shadow at the bottom of the photo. That's because when you have the lens added to the standard kit lens, it adds a couple inches in length. The flash is ever-so-slightly blocked at the bottom of the photo, but the same thing would happen with a telephoto lens. Again, all you have to do is zoom in a little closer...or buy a flash that sits a little higher (on the shoe instead of the lower-sitting built-in flash).Just buy it....you won't regret it at all.Dave

I'm just learning to use this effectively, and I thought I'd share a few observations:1. If you are using the only the macro component , DO expect some vignetting. Not terrible, because if you are going in that close, you'll probably want to crop.2. If you are photographing insects, unless you have a very steady hand, and the insects are cooperating by staying in one place long enough, you'll need a tripod. For example: bees collecting pollen from flowers - set up your shot, use a wireless remote if possible, and wait for the critter to come back again ... if it lands on a nearby flower, you can quickly adjust the tripod, but not if you have to refocus. You just won't have time.3. The depth of field is VERY shallow, but you should be able to do micro life, and the blurred background is an effective method of drawing the viewer's attention to the center of attention.4. Always use shutter priority with this lens and set it at the fastest shutter speed acceptable for the lighting conditions. That could also help a lot with "hand shake" if you are stuck without a tripod.As for the wide angle fish eye component , I can't tell you much right now as my experiments have been limited. I just received the lens this morning. I hope to post more in a few days.The photos below illustrate some of the issues:The left most shows why the tripod is so important. Both the left and the right photos also illustrate the vignetting. The center photo was cropped, and although I didn't use a tripod, I was able to maintain my steadiness - because for some reason the smaller fly didn't seem to flit around as much and I was able to relax to capture it. It must know the difference between a fly swatter and a camera.PS - The left photo was supposed to be a bumble bee, but I selected the wrong image from my library. I am posting the bumblebee now. By the way, look at the fly again and you can see how sensitive this is to depth of field. The wings are sharply in focus but the head which is in a slightly different plane is blurred. Just something to consider when setting up your shots.

An extreme wide-angle lens, and impressive macro - feature all in one affordable, sturdy piece of kit.The 18- 55mm wide-angle lens, a 55-200mm zoom, a 70- 300mm zoom (nice, but not absolutely necessary) and a prime lens are almost all you need to be a well-rounded amateur photographer.Add to that this unique lens, and you have it all covered.Spend the very low cost of this machine and enjoy the places it takes you.

Very cool lens for the price.Looks cool, and gets the job doneFit my 58mm 5K I grabbed on here and thecombination of the camera and this lens has me more excited to take photos than ever!!I love taking photos with my phone, but with lenses like this. I am back to a proper camera and attatchments. Too much fun! Affordable photo fun!

I bought this for my Nikon D3400 to attach to a Nikor 35mm DX (non-zoomable) lens. It yielded less than acceptable results when used indoors and with flash. It made all my pictures have a dark yellow tint to them (see attached photos below) Both these pictures were taken with flash ON. It works ok when used outdoors on a bright sunny day, but the pictures turn out darker than normal. Not to expect so much for a 25.00 lens, it's just an ok lens. The macro lens works great, though. Still a bargain for the price.

have not used it yet take pictures of sunsets lakes

A very sturdy, well built attachment that does its job well for the price. Depends on which 52mm lens ur attaching it to. Gives a diffrnt effect on a 35mm and a different angle on a 18-55mm paired with Nikon D3200. The macro is good with a tripod amd close to ur subject. Insect photography is best with dead insects!! A must buy if u wana experience Fisheye n macro b4 u go for the biggies. Good seller, came wall packaged n on tym to Calangute goa.

Nic but my expectations is more..... But its ok on this rate company give you fisheye effect which is more important....

You might think that this is either junky or won't work because of the price but it's the exact opposite. Not only is it very well made but it functions amazingly.

Not good item.please don't purchase it
