Fantastic fun lenses. Well built and takes very nice photos. But it is extremely difficult. If you have not photographed macro before you buy a regular first otherwise the risk is that you give up with this as the first. Do you know what you're doing, it becomes not so much funnier than this.

Not much to say, awesome!

An amazing lens if one is aware of the limitations and nitrogens for it to work. This lens is worthless without a macro flash as Canon MR or MT flash is a must. It lacks autofocus, but it is not useful in this type of macro photography. One can not be portrayed bumped objects than 1:1 so it can not be used for anything other than macro. This lens is made only for macro photography and it does it well. Flash is a must even if the lens is an f2.8, it is not useful at lower than f8-f11 if you can not do with a focal depth of a few hundredths of a millimeter.
