Neewer TT560 Flash Speedlite for Canon Nikon...
581913
Received it early loaded the batteries and started shooting right away.  I'm new to the still photography game, but I do like it as a new hobby and discipline.  I couldn't justify buying anything over $50 much less anything that is $150+ just for something to get used to.  The flash is very bright at full settings and the slave settings works well too and at this price getting another flash and a remote for lighting effects is something I can do without destroying my wallet.  I'd recommend this to those who are new to the game and aren't going for pro status.

This is the second flash I purchased for my  Canon Rebel EOS T3i.  After reading rave reviews for another (I assume based upon price and functionality) I purchased a much cheaper flash.  I am an advanced amateur and to be honest did not want to spend more on a flash then I needed.  If you want to know how I felt about the first flash, check out my review.  To be honest, a couple of responders berated me for being unhappy with the previous flash product and said I should just learn to manually make the necessary adjustments on my so-called "automatic" flash.  I was scratching my head with those comments since I thought the point of an "automatic" flash was not to have to do that, but according to them I am wrong and should always expect it necessary to make "some" manual adjustments.

Well  -- out of the box and with a firmware update that was available for this flash on the manufacturer's website for my camera, everything is working great and exactly as I had expected flash #1 to work.  If you are buying this for a  Canon Rebel EOS T3i, it would be helpful if they somehow told you the need to do the update (else the flash doesn't work with this camera at all to the best of my knowledge).  But there is an update from the German manufacturer and you need to get it for the  Canon Rebel EOS T3i.  I assume at some point the firmware will be updated on all future production models, but I do not know how that works by manufacturer.

All my pictures have been great, though once again, I admit I really don't take that many flash photos.  This flash is intended to be equal to Canon's own top of the line Speedlite flash for the Canon Rebel EOS T3i but is a $100 dollars cheaper on Amazon.  On the other hand, it was slightly more then three (3) times the cost of the Polaroid branded flash that did not work for me at all.

Although  I did not purchase this particular product from Amazon, I do own it and use it regularly. The YN-E3-RT is compatible with Canon Speedlites that have built-in wireless remote capabilities. This list includes the 600EX and 600EXII series, the 580EXII and the 480EXIII series. It also works with the YongNuo YNE3-RX wireless flash receiver.
For all other Canon compatible speedlight units without wireless remote, the RNE3-RT receiver will allow these speedlites to be used wirelessly. The ETTL features will also be available if the speedlite has this capability through the hot shoe.
The only reason for the 4-star rating is that this trigger has a wonderful feature not found on the Canon or other flash triggers compatible with Canon. that feature is that the YNE3-RT has an Auto Focus Assist Beam. When it works, that is. I have contacted YongNuo and their reply is that this is a known issue and they are working on a firmware fix. If they fix this, I will change to a 5-start rating. I must comment on the AF Assist on this unit, it is not just a blob of light transmitted , but a pattern of crosses that the auto focus in the camera locks onto quickly. Canon, take note, this is a much needed feature!

I bought this specifically for my Indra 500 strobe. It works as advertised. It allows me to switch between manual and TTL quickly and to adjust from the device. Remember to set your Nikon to FP mode (read your manual) before attempting HSS.

I'm using these to trigger multiple Yongnuo YN560 IV speedlight strobes with built-in receivers and they work flawlessly. Since the speedlights have the receivers built in, you only need one of these mounted in the camera hot shoe. If using a speedlight without a compatible receiver built in, you can use the second RF-603 II to fire it. I just keep the second one as a spare trigger.

I also have the Yongnuo YN560-TX flash commander which triggers the same strobes, but also allows you to adjust the flash output and other flash settings. The YN560-TX also sits in the camera hot shoe but is considerably larger. However, it will still make all the flash adjustments even if it's not mounted on your camera. So I find it useful to make the adjustments using the YN560-TX commander which I can keep in my pocket and put the RF-603 II on the camera and stay streamlined.

If you're looking for a great manual flash alternative to expensive dedicated strobes like Canon 580ex or Nikon SB-900, this YN560 is definitely worth considering. As for iTTL, CLS, and automatic features - if you need automatic, this is NOT your flash. Obviously there's no comparison for using dedicated flash units mounted on your camera. That's not what the YN560 is about. It's about quick and easy off-camera 'strobist' work where the more strobes you have, the more you can do. Since you can get about 7 of these for the price of 1 single name-brand strobe, this pretty much kills comparisons of reliability or flexibility. I'm not sure of long term reliability yet, but at this price just buy a spare... or 3!

I just ran 2 of these on radio triggers along with a Canon 430ex (which the YN560 is very close to in power) and powered by Energizer 2300 NiMH's. It was a 5 hour shoot, and in over 600 frames not once did these ever misfire.

Pros: Recycle time with NiMHs is crazy fast. The 'beep' on recharge is a perfect way to verify they went off. Build quality is jaw-dropping for the price. Head is the same size as the Canon 580 so it takes the same size Stofen and other size-specific accessories. LED Lights for power level can be seen and adjusted easily WHILE mounted high on a light stand. (Canon units with the LCD always need to be lowered on their stands to adjust them). Level/zoom adjustments on the YN560 are one or two button presses (compared to Canon's where you have to hold down the select button for 1-2 seconds, then make adjustment, then 'select' to set).

Cons: slightly strange power-up on both units I received - if the zoom is set at anything other than 105mm setting AND the flash is being turned on from a cold start, it powers back off requiring another power-on cycle. Once they've been turned on though, it doesn't do this. Since both of mine do exactly the same thing I guess it's normal. Only other slight negative is the level display is not marked 1/128, 1/64, 1/32, etc. it's just a row of 8 lights (marked for zoom setting). What does it matter really? It's manual flash so you're doing test pops anyways, and when you change a power level you're just going up or down in power by a number of steps. I didn't have any problem getting them set exactly where I needed, I just had trouble thinking what the Canon needed to be set in comparison.

I like this speedlite especially for the price, however it can sometimes be unpredictable with "white outs". I bought it as a 2nd flash for my 2nd camera and could not afford another Nikon brand flash at the time. It has become less unpredictable as I've used it more. But it makes me nervous to trust in a wedding situation. But overall, for the price I'm pleased with the performance. I would recommend this to a friend but I would say use it and get to know it.

I needed a good flash quickly and In my budget...wow Amazon and YongNuo came through for me with the YN-468 II TTL. It worked flawlessly to shoot a small wedding for a friend. I also was amazed for the price it is a master for my non-TTL older YongNuo.

Purchased the Yongnuo YN-565-EX to use on my Canon T2i. So far I've been impressed by it's performance. Does almost everything that the Canon 580-EXii at a fraction of the cost, although I hope to add the Canon flash later. Try it I think you'll be pleased.

I just got this yeaterday. I loaded it with NiMh rechargeable batteries and plugged it into my Yongnuo 560iv flash. The battery pack does as it should. Faster recycling and I would presume longer battery life. It will be used at an outdoor wedding photo booth this weekend so I should have a better idea in a few days.

Great speedlite, very fast recharge and excellent light. I love the ability to charge batteries inside the flash.

FANTASTIC MANUAL FLASH!!! Using it with Olympus along with their controller. Allows for a WHOLE light kit as opposed to just a SINGLE flash for ON-BRAND flashes.  Paired with the ENELOOP batteries, this is hard setup to beat for the price.

I was worried about purchasing this older model of the Canon Flashes since i didn't know if it was compatible with newer rebel DSLR cameras. After researching and getting nothing on google i took a leap of faith and walla! It works wonderful with my Rebel T3! Its sturdy and works wonderful. I just thought i'd write a review on this flash and the compatibility in case there is someone else like me wondering.

I purchased three of these speedlights along with the Yongnuo 602 wireless triggers and both work great.  I have a Canon T3i with a built in wireless system for flash and the flashes work with the cameras wireless system without the Yongnou triggers.  The only draw back is that you can't go beyond 1/350sec. I hear that if you want to shoot faster you will need to go with the 580 line

The reviews for the YH-700C indicate that it is a close functional equivalent to the much more expensive Canon 580 EXII but much more cost effective.  Having learned the hard way between the differences between the manual flash - which doesn't adjust its power from a camera command - to ones that do so via E-TTL.  The YH-700C seemed to be what I needed.

Putting a flash diffuser cap became the next challenge.  I ordered one that fit the 580, but that turned out not to work - too small.  Buried deep in one of the reviews for the YH-700C suggested using a flash diffuser compatible with the Nikon SB900 series.  I just received from Amazon the "fitTek Godox Flash Bounce Light Diffuser for Nikon SB900 Speedlite" and it fits perfectly on the YH-700C.

Now to spend some time to get to know both.

After looking at many different flash units I bought the YN-560 II because I needed a manual flash for the type of photography I do. I don't use TTL so for the price  I would order it. The item was shipped quickly and well packed,  seems to be well made. would recommend it to anyone looking for a good cheap manual flash

This is a good buy for someone who wants to improve the results of their flash photography. It fits both of my Yongnuo flashes very well. It is a little floppy at first but with a little careful forming with your fingers, it works fine. It stows easily in my camera bag or in my jacket pocket in the included cloth pouch.
