Canon MT-24EX Macro Twin Lite Flash for 5D, 1DS, 20D, G3, G5, G6, Pro 1 & Rebel XT/XTi

I do a lot of macro photography in the lab (mostly for forensic engineering work). While I was able to do a pretty decent job with enough available light and my 580EX, there were times that didn't work...and I missed some important shots; but not with the MT-24EX. The flexibility and versatility of this flash unit makes it the "one" to have for macro work. The ability to remove one or both flash heads and aim them right where you want is a terrific feature.

There are times when I have to capture moving subjects, and the high speed sync function works great when you need to push a faster shutter speed but still keep the fill flash ability. And as one of the other reviewers mentioned, you can set this flash for either master or slave mode; works great with my 580EX as a slave unit. I continue to be astounded by the quality of macro photos produced with this flash.


Bottom line: if you're serious about macro work, this flash is a must have.

What a great Macro/Close-up flash. The flash works great lens mounted or by romoving one or both of the heads (they also have tripod mounts on them). This makes this flash so versatile. Excellent Canon quality and performance. Ettl works flawless with my Rebel XTi! It is also able to control a slave and I believe it can also be used as a slave. I couldn't be happier with this flash!

I am an amature hobbyist photographer and I purchased this flash last summer and have used it extensively for my outdoor macro work. Love it.

If you use a Canon Camera and wish to shoot macros,this is a must own product. Expensive, compared to Nikon's version, which is also cordless.

After years of manual flash macro work, recently in digital format with extension tubes on the Canon 100mm macro lens, I decided to cast a onsiderable sum of money at this twin light. Where I used to struggle just to get the correct exposure, now I'm able to concentrate on background (no night-looking flash fall-off anymore) and on modeling the light -- including little shiny aphids tended by ants! If you're serious about great macro work -- this is the flash to have.

I was worried about breaking the hot-shoe mount with rough field work, but the 45 degree angle of the mount adds stability. Even so, I bent up an aluminum strap bracket in my shop that surrounds the camera and flash -- a camera "roll bar."

There's a bit of a learning curve -- but when I tried manually setting the aperature (f22 is my lens's "sweet spot") and a shutter speed of 1/200 -- ISO 100 -- all of the exposures were perfect, because the ETTL function "dials in" the foregrand and background appropriately. I've used the same manual settings for just the macro lens, and for many variations of one to three extension tubes.

I've retired my 25 year-old Cokin flash unit that has served me so well with guess-timate exposures.
