Other features include improved communication reliability through its direct contacts, and recycling time is both 20% shorter than the 580EX and is completely inaudible. Optional External power supply - compatible with Dust- and water- Resistant External Power Pack, Canon battery pack CP-E3 and Transistor Pack E Unit Dimensions - 3.0 x 5.3 x 4.5 inches /76 x 134 x 114mm; Weight - 13.2 oz./375g, without batteries (4 AA alkaline batteries add 3.5 oz./100g)
great product!! (Rating: 5 out of 5) Works great! I love this flash, although still learning how to use it. I certainly don't understand the ins and outs quite yet. This is certainly worth the extra expense in my opinion. I would suggest a diffuser, however.
Great Product (Rating: 5 out of 5) This item is easy to setup and use. It contributes to outstanding photos. Battery life is enhanced by using rechargable lithium batteries.
Great Product ! (Rating: 4 out of 5) Great product. The only thing is I could not get it to trigger my 430ex without it firing too. I followed the manual instructions, but it still kept firing. Overall though, it is a great speedlite.
Great product (Rating: 5 out of 5) I've just started using the product, but so far it fully meets my expectations. Good power, nice color balance, and easy to use.
deceptive Amazon promotion (Rating: 2 out of 5) I don't have any problem with this flash, but I do have a problem with Amazon. It said that there is a fifty dollar coupon, so I assumed (incorrectly) that my price would the 370.00 less the coupon for 320.00 Low and behold I found out 370.00 was the price after the coupon. No one is selling this darned flash for 420.00. I wish flakey practices and gimmicks like this would stop. I'm really frustrated.
