Yongnuo YN-565 EX TTL Flash Speedlite Canon 5D II 7D ,30D ,40D, 50D ,350D, 400D ,450D (Discontinued by Manufacturer)

I am what I consider a Semi-Pro photographer. I do it because I love it, Once in a while I get a paying gig. I do all sorts of stuff including event photography.I bought one of these for my home studio, my portable portrait studio and for some special projects. I wanted something that would work with the Nikon CLS system, I NEEDED something with an external battery pack for long shoots and rapid fire shooting - but I couldn't afford a new SB800 or SB900.(THIS UNIT WORKS WITH CANON AND NIKON BOTH!!!)The 8 "AA" cell external battery pack was about 50 bucks - I was thrilled!  YongNuo External Flash Battery Pack SF-18 for Canon EX580 II EX580 Holding 8 AA Batteries I read the reviews - I saw an awful lot said about firing it 20 times and it dies... I am no stranger to electronics so the first thing I did when I got it was wring it out in the studio. I figured if I didn't kill it the first night in the studio - it may work for a shoot!I fired it off a lot more than 20 times! However - they state VERY plainly in the manual that if you are going to do any rapid fire shooting, use it at ¼ power or below! I cranked it back and had no issues at all.I use this in a big umbrella type soft box with the cord for the external battery pack dangling down below it (I need some Velcro straps!). I fired it off about 100 times in a relatively short period of time - NO overheating, NO issues - it just worked like it should! BUT - If you don't use the MANUAL EV compensation ON the flash (Which over rides the CLS commands, BTW) and crank it back to about -3 or -4 then you will likely smoke the flash head... Just a warning to those who read the other reviews!CRANK IT BACK TO KEEP THE HEAD COOL!I set it up to be a slave on Group C Channel 3 and told my Nikon SU800 remote controller it was there. I use ALL my flashes OFF camera! It fired off the first time and every time thereafter - fully utilizing the Nikon CLS control system as far as I could tell. I use several flashes and one totally manual slave and this unit - I think I am going to LIKE this unit!It looks and acts just like a Nikon SB800 to my gear!In close quarters with the softbox - you really don't need FULL power!The Nikon CLS commands work through the diffuser of the softbox - NO problem at all!The menus are easy to figure out once you sit with the manual in one hand and the flash in the other. A couple of times through the menus and you will understand how to use it in 10 minutes or less. I just had to learn what some of the cryptic things said on the display vs. what the really meant...If you are familiar with CANON flashes - you will figure this thing out in less than 30 seconds... It's like a 560!I like the "hot keys" on the back (instead of scrolling through menu options!) and the display is easy enough to read, even without my glasses! The one touch button to turn on the backlighting on the display is great, another touch, it goes off.I like the audio feedback - it will tell you when it is ready for the next frame - I LIKE that... no more "Ooops, the flash wasn't charged enough for the next frame...." The flashing while in remote mode, always lets you know it is awake.(Turn the "power saver" to "1hr before sleep mode" - you will thank yourself later!)(Crank the power back to at least half of normal - you will thank yourself and it will last a LOT longer... - use the fancy Nikon flash for rapid fire stuff for your rapid fire ON camera stuff and save this from the abuse!)I REALLY like how solid the battery door is - it isn't flimsy like so many other manufacturers. For us old guys, the WHITE lettering inside the door lets you SEE what orientation to put the batteries in - even in low light. As I age and my eyes give out, this has become more and more important! Just a simple little thing - but VERY important to an old fart like me...It "feels" hefty - it doesn't feel like a cheap Chinese flash... It seems to be robust enough to stand up to some serious banging around in the bag for a few years.The zoom feature is a little noisy - but I like that, it tells me it is working!I look forward to using it this weekend on a couple of things and will report back after I have used it on a couple of location and studio shoots. The proof will be told after I shoot about a thousand shots... And the way some of my shoots go - that wont take very long!I usually swap out my speedlite batteries two or three times during a shoot - this one I hope to last more than twice as long as my SB600 and SB700 workhorses. The external battery pack is awesome - I can't wait to "wring it out!"I will report back - so far I am pleased! As long as I pay attention to how HOT I make this thing on wedding shoots and fashion shoots, it "feels" like it ought to be around a while...Finally, an affordable solution for CLS slave flashes that doesn't cost an arm and a leg!*** UPDATE***I shot 348 frames at my last weekend shoot - NO PROBLEMS! BUT - I used it at 1/4 power the entire shoot - it worked flawlessly just like any of my other Nikon Flashes, except for the fact I didn't have to change out the batteries even ONCE!*** UPDATE*** 04/03/2012 - I have used this flash on several shoots now and shot well over several thousand frames with it... It hasn't skipped a beat! It outlasts my Nikon flashes 3 to 1 - meaning I have to swap my batteries out in my Nikon flashes 3 times to ONCE with this little jewel on a long shoot. Just remember - CRANK THE POWER BACK for rapid fire shooting!BP

I've had the flash for a week and just used it for a wedding. Ordered this while my Canon speedlite 430ex ii was away on repairs. Paid the same price for this unit as it was to repair my 430.I've used the 430 before in several senior photo sessions and a couple of wedding and have had excellent results. This flash provides much more power but at the cost of battery life and flash recharge time. I went through three sets of batteries in about 700 shots. With the 430 I would go through 1 set of rechargeable batteries in the same time.Not only that, the flash recharge time got longer and longer the more I used the batteries. I don't recall the same issue with the 430. The 430 seemed to recharge much quicker, i.e. less wait between flashes.The big concern with this flash was how hot the batteries got during use. I could feel the flash getting quite hot as I used it and the delay between flashes reached nearly ten seconds.I popped out those batteries and burned my hands. They were that hot. Put in a new set of batteries and burned through them in another 200 shots and popped in the third set. The first set were still very hot to the touch and I would not have been able to put them in my pocket or hold them for an extended period of time.At no time of using my 430 over the last couple years have I ever felt batteries get hot like this. I've used it for four hour photo sessions without any issues with hot batteries or even the delay between the shots.Ok, now that I've gone on long enough about the batteries... I was very happy with the light output of the flash. It did seem over bright when I had close up shots -- which, again with the 430 I don't recall having blow outs like this unit. Felt at times like I was using in MANUAL mode with full flash power instead of ETTL with the amount of excess flash I was receiving.But, after some experimentation I was very happy with the results. I ended up avoiding too many closeups and did more flash bouncing that I normally do with such a high ceiling. Good note, though, this had excellent flash bounce with a 30' ceiling whereas the 430 would have had problems.Even after the complaints above, I am enjoying the flash and for the money I'm glad I got it. I plan on using it as a manual slave for my 430. I have already used it several times as a slave via flash from the on-board canon flash and has worked pretty well, except where I had extra-preflash -- but I can't fault the slave flash for that.

This flash was great while it last but that wasn't long. As others have mentioned some of these fail pretty quickly. Others seem to be getting better results. I guess I got one of the bad ones.Flash was solidly built and easy to use. Worked wonderfully both on and off camera with my Canon Rebel T5i in both ETTL and manual mode. Took some great shots with it, especially off camera. Then it stopped working at anything but full power when on camera. Off camera or on with ETTL it did not work and could not work at reduced power to enable me to use it as an off camera fill flash or something else. At less than full power it would flash but was either completely out of sync with the camera or at too low a power to have an effect.I liked it enough to be considering getting another but haven't made up my mind yet.

Modo TTL, Modo manual, modo estroboscópico..., cabezal giratorio, potencia y alcance bastante acetable, muy rápido en el reciclaje, con cabezal zoom, menú intuitivo...no pido más y por este precio ni me lo pensé. Tiene varios años desde que lo compré y funciona como el primer día.

Have used for several years, and for the price, this product is difficult to beat.

Superb flash , very easy to use , works perfectly with my canon eos 550d

Prodotto di ottima fattura, le plastiche ben rifinite e di qualità, si integra perfettamente in tutte le sue funzioni alla mia Canon 70D, permettendo il settaggio dal corpo macchina. Lo consiglio a tutti sia il fotoamatore che il professionista avrà ottimi risultati ad un prezzo decisamente onesto.

Je cherchais un flash E-TTL pour mon Canon et celui-ci est exactement ce que j'attendais. La fonction E-TTL pour des shootings courant sans prise de tête et des réglages dans tous les sens lorsque je veux peaufiner. Il fonctionne parfaitement et sa construction me paraît sérieuse et solide. La notice est en anglais mais j'ai téléchargé la version informatique que j'ai traduite. Le prix est très honnête si on compare avec d'autres marques. Il existe même des filtres colorés adaptés à ce modèle.
