SigmaEF-610 DG SUPER Electronic Flash for Nikon Digital SLR Cameras

First things first, I am a professional photographer (ALL of my income comes from my photography). I rely on my tools to function when I call on them to. I bought this as a supplement to my 430 EXII's, and intended on using this as an on-camera master to trigger the 430's as remote slaves. For this, the flash has worked perfectly. If you know how these systems function (i.e. This is line-of-sight, not a radio-trigger), and set up your lighting accordingly, the flash functions flawlessly. I've used this on 2 shoots in the first 3 days of having it and it's made my life easier and my lighting set-ups more versatile. I'm looking to get a speed ring to test this mounted onto a light stand and shoot with a soft box or beauty dish, just to compare it to set-ups more similar to Alien Bees. This has a portability advantage vs. AB's though, seeing as it's lightweight, easy to store and more importantly, battery powered.As to the battery aspect, this recharges far quicker than I expected it to. In fact, i swapped out the expensive Lithium Extreme batteries (that I bought for $2 a battery) and started using cheap Costco AA's on the second day because this recharged so quickly. I'm not an electrical engineer, but I didn't notice much difference in performance between the two and I was shooting for an hour and a half at 1/4-1/2 power the entire time.In conclusion, if I had to make a complaint, it would be that the + and - buttons feel reversed to me (the '+' is on the left, '-' on the right; it's counter-intuitive) and the zoom button is a progressive step (24-28-35-50-70-85-105) and not a single 'push and select' that then takes + & - inputs. So my two complaints are based on the fact that the Canon menu system is superior, but the flash head itself has taken every task I've asked it to and run with it.I'm considering selling my 430's and picking up a few more of these, simply because of the power, portability, versatility and price of these units. If you're looking for a less-expensive (I won't say "cheap", it's still $250) alternative to the like-branded flashes, I'd highly recommend this unit in a heartbeat.

If you're looking at this flash, you're probably looking for a cheaper alternative (or simply another) flash to the equivalent brand name model. I purchased this over the Canon Speedlite 320EX for my 6D, to which I was comparing based on price. I don't have the Speedlite, so I can't offer a donuts-to-donuts comparison, but unless you are adamant on same-brand compatibility, I believe it works well enough.The flash is strong enough for its price point and has numerous features and settings, including wireless control. Here's where it gets iffy: it's got quite a few functions but the manual is a bit convoluted. There is a bit of a learning curve, so for beginners, the best option is to set it to the 'auto' setting where the device will try to match the flash strength with your lens's focal length. It's not perfect but in a situation where the rest of your body is too busy trying to adjust to a moving object, it helps to have one less thing to manage.EDIT 3/14/2014:In a regular-life situation (i.e., you are physically moving around), using anything but the automatic setting is difficult. Several button presses are required to manually adjust settings and there is a bit too much functionality when you just need it to work in the heat of the moment. However, leaving it in automatic DID turn out to be great. I took this to an outdoor concert in Seoul in below-freezing weather and it performed admirably. Even from about 10m/30ft away in dim lighting, the flash produced noticeably better results than without the flash. My recommendation is just to leave this flash on auto and manually adjust your DSLR/lens.

I bought this flash a couple months ago, and I am really glad I chose ths one. I'm not a professional, and I have a lot to learn about flash photography, but I have found it to do a very nice job for most of my needs. I love how easy it is to program the flash power (1/1 to 1/64), and the guide number is impressive (61m/200ft.), althought I think that is a bit higher than what you actually get (I've heard the same about all the other flashes out there as well). I also am impressed with the advanced features on this flash, such as wireless TTL, high-speed flash, and rear curtain sync. You can also use manual flash mode if you want to enter your aperture and have it tell you what your distance from the object should be. My only beef with the flash is that the manual mode (and the user's manual) are a bit tricky to figure out, and the LED display letters are pretty small, although it does illuminate, which is nice. Overall, I really love this flash!

Very good flash, for most work! Just a little slow to recycle, which can be a problem at some events! Works excellent, otherwise!

You really do get what you pay for. As a pro photographer, I shoot mostly indoor monolights. I purchased this as a back-up flash to my Nikon SB 800 for shooting outdoors and when traveling. The construction seemed sturdy enough and output specs put it equivalent to the SB 900 at half the price. After only a couple of months I began having trouble getting the flash to turn on. The fault was the flimsy plastic battery door, which eventually failed altogether leaving no power to the unit.The rest of the flash construction seemed good. Why would Sigma scrimp on a cheap plastic part that is so critical to its function? Beats me!By the time I figured out what was going on, the thing was past its warranty, and I was done messing with it. I recently purchased a SB 910 as its replacement.

Très bon flash.

Todo perfecto

問題なく使用できている

Die Lieferung erfolgte schnell, die Verpackung war einwandfrei. Das Sigma EF-610 DG Super verwende ich an meiner Nikon D7500. Es hat eine sehr gute Leistung und lässt sich unkompliziert bedienen.

Vraiment décevant. Il se recharge extrêmement lentement, alors qu il est stipulé qu on peut faire du rafal avec. Ça fait plutôt 1 photo toutes les 20/30s.Je l ai renvoyé
