Document: Generally quite good but modeling light feature is not working in Nikon iTTL slave mode. Other than this everthing is fine.
Look how many people have been through this 'dud' experience and have posted their experience. Avoid anything YongNuo at all costs unless you are willing to kiss your investment goodbye in three months. And even if they come back under another name I am going to find out and tell everyone about that name too.
It works with D7100. I havent experienced any prblem so far.Slave function was important for me and It Works with D7100 so I can use as external flashIt is difficult to open diffuser, It is too tight but it is not a big problem for me
It saved the day at my wedding shoot!The head turns at various angles, similar to the SB600/700/900Works well on both cropped and full frame DSLRs.If you're in a pickle, this is a great cheap alternative until you grab a replacement....Also, it works amazingly as a slave/off camera flash as well.
This flash works great both on camera and as slave in both iTTL and manual modes. There are no indications anywhere on the box or manual that there are two different versions for nikon and canon. There is a setting in the UI for the two camera brands. One limitation is that it can't do high-speed sync (above 1/250). If this feature is required for your use, then this flash is not for you.
That is...it does not have high speed sync. Outdoor weddings can also present the same eye shadow issues. If you need this capability...get a SB-800 or SB-900, or a portable reflector.2. My YN565EX does not have a slave mode...where it fires using another flash's output as the signal. If you want an inexpensive way to do this, you can get the YN-560.3.
I don't think you can beat this for the price. I had a YN-468II before this that had some defects so I was a little bit apprehensive about this one. Don't be. It worked out of the box and performs as described. Slave one and Slave two are useful, but the most useful feature for me was that this is compatible with the Nikon CLS on my D200. I've ordered a second one to complement the first and will be using both extensively in the next couple weeks.
Three stars only because it is cooking the batteries! I bought two of them, when it comes to performance it is great, nice soft light compared to my Nikons, ok menu, built is not as good as Nikons but is ok, the price is the best, perfect for slave! Problem is, when I put new alkaline batteries, it will fire 10 times and it turns off by itself, when I tried to turn it back on, it will start to show a "no power" display.
Its Amazon price varies tremendously, depending on which current vendor, but prices under $120 are impressive, almost as good as Ebay.The YN565EX works great on my D800 and D300, as manual flash and slave, or as hot shoe iTTL, or as a remote for the Nikon commander. No warranty expected from China, and a couple of minor features are not actually implemented, but performance is great. This is the inexpensive way to get first class flash. A review is at [...]
As an owner of a Nikon branded speedlight, I was hesitant to spend $200 on an unabashedly Chinese-made "off-brand unit marketed as directly comparable. I was pleasantly surprised, however, by its build quality and functionality. Although it has limitations (syncs only to 1/320, LCD graphics are archaic and oddly abbreviated), it will be an excellent back up and slave unit. It reacts perfectly to the Nikon CLS signal and even has an available power pack.
Answer: I don't know What you mean with "slave cell". But It has slave function. It has optical slave capabilities which can supports TTL. In this method It uses infrared. It also has simple slave function which means it can be triggered simply by lights of built in flash.
