excellent coverage range... from 18-105. canon flash system isn't as advanced as nikon's, but with a little help from an omnibounce and the ceiling, this flash can match any nikon product. the output is very high with this flash. build quality is decent. get a quantum battery or the canon dedicated battery and you won't miss a shot.

this thing is LOUD! turn iton, hear it whine, hear it zoom, hear it fire, hear it whine some more.

a great pro caliber flash, although already obsolete due to intro of e-ttl and 550ex flash. that just means it is a whole lot cheaper to own now! get the 1n/540 combo with any lens and experience great results.

This is a strong flash with a great deal of usuable features. I love the seperate flash exposure compensation mode.

This flash really nails the exposure and is a joy to use. I use this flash a lot and it has never failed me. I use it set with -1/3 exposure compensation for most portraits and casual shots of kids indoors. Great flash well worth the money.

BOOM!!
It's da Bomb. Great FLASH. It's smart. and if you use it within it's ranges you'll get great coverage.

Uses up the AA's pretty quick. Motor is a little noisy.

Great Flash. Used with the 1N.
Go with the A2 when I go close quarters and don't want to lug around alot of equip.
Love It.

Very "smart" flash unit, has all the overrides and second-curtian sync, plus accurate TTL. The fill-flash program is just right for outdoor work. Ideally suited for 400-speed film.

Doesn't work particularly well with Nicads, but the CP-E2 is a MUST accessory; it allows the flash to recycle almost instantly and you can get over 100 shots using TTL before you need a change of batteries. Highly recommend the use of NiMH cells. As previously mentioned, the 540 EZ is a battery eater, but any flash with a zooming motor will be hard on juice.

A great flash unit for moderate-to-heavy use. The 540 EZ is very reliable and works wonders on overcast days with fill-flash. Like most clip-on flash units, it really is designed to work best with 400-speed films. Yes, get the CP-E2 if you do a lot of shooting, as this will allow you to get the most from the flash unit. I confidently use the 540 EZ for weddings, with great results without a lot of thinking.

first one I had that has a locking pin, exposure confirmation light, locking bounce head---as well as the powerful range.

haven't found any yet.

With my 1n and the 540's flash range, taking sport pictures at night is a breeze! I love it!

Not on this flash, but when my 420 got hit, Canon's customer service was great!

Powerful and easy to use. Stobe capability and flexible bound head.

No wireless capability.

Powerful and easy to use. Any EOS camera without ETTL should have this flash. If you do bounce flash often this is it.

It is expensive. If you really need one, get it. Otherwise, try third party's

I am using Leica lenses on Canon EOS bodies (via Novoflex EOS/LER-adapters) - and I am getting super flash pictures. The Omnibounce
attachment is giving me some very nice skin tones.
Can be recommended highly.

This is a great flash, much better then the sigma ef-430 st. The light is great with the omnibounce. It also makes the camera focus faster, when you use the AF-beam.
The buttons are big and good. The backlight is wery usefull.

Can be a little heavy when you use the hot-shoe extender 200.
(But if you workout a little, then it shouldn't be a problem)

This is the best flash for the Canon eos 1n, becouse it is dedicated for that camera. The light is great, and much more natural then the Sigma EF 430. The head is good becous it can turn left and right.
I've seen a review where a Truc sees that the flash is wery loud, that you can hear it zoom and fire. Well then he hasn't used the Sigma EF430, that is loud. More then twice as loud as the Canon Speedlite 540EZ. It's silent!!
