What kind of macro lens is this ?

? its pretty cheap 12$ ....

Its to screw onto existing lenses to increase magnification (reduce minimum focus distance).

It is a 10x diopter. It screws into the (front) filter threads of any lens and magnifies the image. Not really good quality. You'd be better off getting a cheap manual prime lens (50m, 28mm) with a fast aperture and reversing it onto your camera. A little more. But if you are lucky you can do this for less than $50.

There are many options. Not all of them cost as much as a dedicated macro lens. And pretty much all of them are going to result in better image quality that than diopter.

Read this for a good macro primer.

I guess you are still looking for a few more purchases before heading home?

I just can't stop its like a virus lol . I just spent whole budget on the 55-250mm lens and I look for some cheap macro lens for bugs and stuff but I won't find it it seems

The 55-250 is a pretty good lens. Just don't put a cheap UV filter on the lens. Those really kill quality.

Do to a camera shop. Ask them for an old manual prime lens. You can get one for $30 (maybe less). If you get a 50mm f/1.8 for example (those were pretty common back then since they were the typical kit lens) and a reversing adapter you almost get 1:1 macro. With a wider lens you will get higher magnifications. The reversing adapter is around $10 from e-bay. You need one that matches the lens' filter threads. For example, 52mm to Canon EF mound. This would be the cheapest combination yielding pretty good results. You will have to manually stop down your lens, or shoot wide open.

Or, for a bit more money, get the Canon EF 50mm f1.8 mark II and a set of kenko DG extension tubes. I think you are looking at $130 for the lens and $250 for the tubes. But you retain full electrical control of the lens. Aperture being the big one. I believe the tube set consists of three tubes measuring 12mm, 24mm, and 36m in length. (It has been a while since I looked that specific information up). That will easily allow you to shoot up to 1.5:1 with a 50mm lens.

If you are aiming at higher than 1:1 magnification then better start thinking of adding an external light source (flash) to help illuminate your subject.

The 55-250 will do about 1:3 magnification. If you want to get 'closer', crop. Cost: zero.

First of all it won't even fit your lens. Your lens needs a 58mm and the one you show is a 52mm. If you want to get a macro lens for next to nothing buy yourself a Macro Reverse Ring Camera Mount Adapter. http://www.amazon.com …rse-Adapter/dp/B001G4PA36

@ OP- you asked in a different thread- and the answer is still the same- in my opinion. The best thing for you to add to your kit would be a set of extension tubes, preferably AF extension tubes.

Those screw on auxiliary lenses- aren't very hot- probably ok for video- but not much more. But video is much lower resolution than still photography is with your body. those sellers know that the majority of buyers are looking at it for still photography- but their aim is to sell you worthless crap for whatever they can get.. Bottom feeders, if you ask me.

And how would I use that ? On my 18-55 ? or just put it ?

You can't use it on either as both of your current lenses are 58mm threads. To be honest, you would not even want to use it even if it did fit. As others have said here and in your other thread, extension tubes or cropping are your best options short of purchasing a true macro lens. Researching anything else is time wasted that would be better served using and learning what your gear can do.

ok guys thank you

And I suspect that the price reflects the quality.

It screws to the front of your 18-55mm lens. Then you turn your lens around backwards and attach it to your camera body. You need to manually focus and zoom your lens, then take a picture. You can get up to 3:1 with a reverse ring set up and that lens. Just be careful not to bump your lens on anything as there is nothing to protect your lenses rear element.

Reversing adapters are best used with manual aperture lenses like in the photo you posted.

The 18-55mm lens has no manual controls for aperture. Stopping down a lens for increased depth of field is very important in Macro photography.

A better solution is "Auto" extension tubes which allow both AF and aperture control.

My friend uses a Nikon kit lens with a reverse ring adapter and it works really well. He does have to manually set the aperture and manually focus as well.
