Life-Size Extender & all ef mount lenses
 
4 Attachment(s)
I recently read a thread in another forum that stated that the Canon Life-Size extender EF, even though canon says it only works on the 50mm f2.5 macro, actually works quite well on all canon lenses. I found one, brand new on ebay for $160, so I thought I would buy & experiment & sell it if I didn't like it. Here are initial results using both the 100mm non-l macor & a Sigma 24-70 f2.8 HSM. Camera distance to the subject was consistent with & w/o the extender for each lens. Lighting & composition would be much better on an actual shoot, but I just wanted to put these together for a quick compare. All comments are welcome, not interested in critique on lighting, since I just popped a flash on & took some quick snaps.

Because of minimum focusing distance, I had to raise the tripod about a foot w/o the extender, so magnification isn't quite as much as it appears, but it is important that the extender reduces minimum focusing distance.

The signficance here to me is that this turns a 100mm macro into about 140-150mm, still with the excellent sharpness, & gives you an extender that will work on any ef mount lens to use as either a "macro in a pinch" or just provide extra reach. One thing to note, with the life-size extender, AF becomes almost useless, especially in low light, so it really only makes sense to use it in MF mode.
