Works perfect for my use. I have a Canon flash that is comparable and this one is just as good. I would recommend it to others. I have been using it on a stand and an umbrella in the studio for fill light.

Rating: 4/5Things I like:-Extremely bright full power output-Quiet zoom operation-Sturdy build quality-Straightforward operation-Includes high quality carrying case-Functional high speed sync-Sub 3 second recycle time with beep feedbackThings I don’t like:-Lack of i-TTL / e-TTL mode and automatic zoom-Light output doesn’t fill the frame evenly-No master wireless modeSummary: The KF-570ii is quite a good piece of kit with a decent build quality and bright output. This flash has a lot of power, but it tends to be focused on the center of the image. This means that the flash would be best used in a studio setting as a manual remote flash with a diffuser such as a softbox. You must understand what you are purchasing before you buy: this is a fully manual flash, meaning it will not automatically determine exposure. If you can find a use for a fully manual flash this is a good product to consider.-------Full Review::Build Quality & AppearanceThe KF-570 flash is well built, with a solid plastic frame, smooth head rotation and springy buttons. It doesn’t have much in the way of weatherproofing, but I see a fully manual flash as more of an indoors/studio kit anyways. The screen is easy to read with a bright backlight but only contains minimal information (power output level, zoom and mode). One thing that really stood out to me is how quiet the zoom motor is. I’ve got a few budget flashes lying around and the zoom motor on all of them are at least twice as loud. The quiet motor makes the flash feel a lot higher quality and inspires confidence in its longevity.::FeaturesThe KF-570 is about as basic as they come in terms of features – it is fully manual, meaning no TTL, no automatic zoom and no autofocus assist light. Because of its simplicity, the flash is very easy to operate and the buttons are minimal. It’s straightforward enough to just set up and go. On the plus side, this flash would make a good slave as its wireless mode works flawlessly and it puts out a nice loud indicator beep to let you know when it is recharged. Power can be adjusted in full steps or 1/3 incraments and the zoom ranges from 18mm – 180mm, though at wide angles the light does not fill the entire frame (see ‘power output’ for more information). The head can be tilted 90 degrees and rotated a full 180 for bounce. There’s no button to depress to rotate/tilt, it just goes with a little force.::Power OutputThe flash has bright output, brighter than both my mid-range Nikon and Neewer kits. Unfortunately this comes at a price, with a large hot-spot in the center of the frame. When the flash is zoomed in, the hot spot is far more noticeable, with the light being very focused in the center of the frame. Using the flash at its widest zoom setting with a 50mm lens would fill the frame, but with a 24mm lens and the flash set at 24mm there is a significant vignette effect. Zoomed in past 50mm and the effect goes away, though taking a wide angle photo with the flash zoomed in shows just how bad the effect is. The Nikon and Neewer flash still manage a smooth circle of light whereas the K&F flash has much more scattered hot spots (see attached photo). This flash would be best used in a studio setting with a soft box or other diffuser. Also, the bright output combined with high speed sync makes this a good flash to use in bright daylight situations. Note that the camera is set to the same settings on both the images compared below.::Other NotesThe included carrying case is excellent quality and the flash also comes with a plastic diffuser cover as a nice bonus.::ConclusionA fully manual flash is good for a beginner who would like to learn more about how cameras work or for professionals who are operating a wireless or studio setting where lights do not need to be adjusted often. It’s not as useful in situations where time is of the essence – for example, portrait or event photography. The K&F Concept KF-570ii is a well built flash with a strong output, but the lack TTL function is disappointing.Robert D.DrekiTechPlease note: I received a discount on this product in exchange for an honest review.

This is my review of the K&F Concept High Speed Speedlite Flash for Nikon and Canon DSLR cameras. To be honest, before getting this product, I had high expectations – having been a product tester on Amazon for a while now, I understood that $79.99 was a price point that was relatively high in “Amazon currency” as I like to call it. My expectations were met for the most part, with some aspects being surprisingly better and some being worse than expected.Just before I get the review started, I would like to disclose that I am no professional photographer, and I have a beginner to intermediate understanding of photography and cameras. Keep this in mind when reading my review.☯ COMPACT REVIEW▅ ▇ PROS+ Very well-built & robust+ Metal hot shoe lock is secure, but not too tight+ External flash is very secure when lock is tightened+ Feels very nice and solid & heavy in the hand, but not to the point where it’s overweight.+ Built-in bounce card & wide-angle diffuser(wide-angle diffuser is unnecessary for any lens narrower than 18mm)+ 8 steps of manual control with 1/8th stop increments(1/128, 1/64, 1/32, 1/16, 1/8, 1/4, 1/2, and 1/1)+ Very intuitive controls with tactile rubber buttons+ Screen text is CRISP with bright LED backlighting+ Tilts vertically from 0 to 90 degrees+ 270 degree head rotation+ Manual zoom available+ Max 180mm zoom range+ High speed sync: the K&F flash manages to go up to 1/10000s, and with faint lines on 1/20000s.+ 2.9s recycle time+ Features 3 modes: Manual mode, S1 mode, and S2 mode+ S1 mode is SUPER sensitive and fires every time, as long as you give it time to charge.+ S2 mode – will only fire once your master and 1st slave have fired.+ Very nice, high quality fabric pouch included – great for travel & carrying around+EXTREMELY helpful instructions manual – I was able to learn most of the flash’s features during my testing from the manual.+ Blue LED indicator for notifying the user when the flash is charged+ PC Cord Socket available+Charge beep feedback to notify flash is ready for action▁ ▃ CONS- No TTL function- 4 AA batteries required are not included(I got them at my local dollar store for about $2. No big deal.)- No PC Sync cord included- No battery level indicator- No automatic (auto zoom) mode- No master unit control▇▇ VERDICT ▇▇This external flash is perfect for beginning or intermediate photography enthusiasts – the flash offers enough functionality to get some quality shots, at a price point that is reasonable, and then some. I remember a time when I went into a Best Buy store to find out that external flashes for DSLRs from Canon or Nikon or other famous brands cost more than $150 – it’s quite amazing that there’s products like the K&F external flash these days, bringing flattering quality and functionality at an affordable price....***Note that I received this product at a discounted price for testing and review purposes. I aim to produce reviews that are helpful for the average consumer, and also helpful for manufacturers in improving their products. I do NOT promise positive reviews.

K&F Concept Flash Speed.I used this product with my canon still camera, photo attached.Build Quality.Its medium quality material but is perfectly justified for price. I have seen Sony and other better quality but there are quite pricey. It is made of good plastic material.Usage Experience.• It was easy to fit on the cannon camera.• It was ready to function straight way without adjusting settings• Big LCD Screen to display relevant information• Its manual is well detailed, you can use the level of flash throwing out considering the distance and light of object and surrounding and yes to save battery life too.• There is a comprehensive guide book but I normally prefer to learn while using it :)• Good for beginners, small parties, outside and well lit areas with short distance.• Fully tilt function to focus your light and control the amount the light of flash you throw considering other objects while photographing• I had no speed issues with this flash using my cannon camera.• I took a lot of pictures in many different settings and I never had any heat up issue, I can see it’s a good quality product at this early age.Negatives• Its not like top built quality but it is well worth compared to price.• It's good for starters with short distance photography and well lit area• I had slight compatibility issue with one of canon camera but it was not a massive issue.ConclusionIt is an excellent product for new users or short distance well-lit area but it has given me an excellent photography experience. I also shared this product with my colleague who is a professional photographer. He highly recommend this product to me for my personal and holiday use. He could not find any fault but he recommend some extra accessories and some tips to get best out of this Flash.I will give 4.0/5 compare to big flash gunsOr 5/5 as value for money.

I'm very into my cameras but mainly for video, however, i like the odd bit of photography, but the room of which i shoot in doesn't have the best lighting and have been shooting in some venues lately where there has been little light and I have found recently that a flash has been essential.When it first arrived the box looked nice and premium, getting into the box you are greeted with The flash itself, a protective box, a Mini Stand, a Reflector and a user manual.The flash is really easy to setup and use, the flash requires 4AA batteries which are sadly not included. Once you have inserted the batteries, you mount the flash to your camera and your good to go. You press the shutter button on the camera and it will do it's thing. My first thoughts were that it would take some setting up but i was wrong.The flash is well built and sturdy, it is simply mounted to the hot shoe mount at the top of the camera and is secure when done so.The Speedlight can be angled up and down 90 degrees and the head can also be adjusted left & right 270 degrees so it can be used in different situations.This flash is amazing, it has improved my photography dramatically, There is many different affects and settings you can do with the flash to give the shot a different look/ style, it is also great for shooting in different situations.Overall i love this flash, it is has improved my photography allot and was really easy to use. It is an essential piece of kit to add to your camera gear. Very impressed!

Very impressed with this flash and its price. Arrived pretty fast. I could use it with both my canon and nikon cameras. Really excellent.

Supplied for review.You can't take proper photos without a proper flash.don't you just hate flash? I mean generally its' actually the worst and I don't know who even uses it. What you need is a bounce flash.This bounce flash can act as a normal flash if you tilt it forwards but when you tilt it upwards you basically illuminate your room for a split second and the idea is that you achieve perfect illumination without shining a light in someone's face and making them look really ugly/see loads of reflections.This works on anything and normally when I take pictures of things in low light it really annoys me but with this you can take the perfect photos.See my photos for pictures of the product and I really should show some pictures that I have taken with this flash!!I didn't bother reading the manual and I have never used one before but I just played with the settings a bit until I got the photo I wanted and I think I would be able to do that in the future too - it is not too hard but takes about 10 minutes to get the hang of it!Please feel free to ask any questions or make a comment. It also comes with a stand so you can use it as a wireless flash gun.

I was sent this item to review.In my line of work, one of my jobs is to take photographs of events and activities that go on in the school I work at. I am by no means a professional photographer, but I wouldn’t call myself a complete newbie. I’ve got a basic grasp of cameras and how they work etc as well as being pretty tech savvy.This flash gun from my point of view is fantastic. From the outset, it is packaged fantastically, firstly coming in strong cardboard casing and then in its own ‘product box’. Inside is a case, the flash, a cover for the top of the flash and an instruction booklet. The English section of the manual is located towards the back, fear not.Once I’d loaded it up with 4 x AA batteries (not supplied) I powered it up to the sound of nice little jingle. I noticed that the blue ‘flash’ light had illuminated so I gave it press. Once my eye sight had been restored, I realised that this button sets the flash off!! Using the mount on the flash gun, I slid it on to my camera (an Olympus E-M10) and turned the camera on. As soon as I pressed the button to take a picture the flash gun fired automatically. No need to change settings or anything like that – it just worked! I was very surprised. On the top of the flash gun, there is a pull out diffuser should you require it and on the back is an LCD display (which illuminates if you need it to) which enables you to manipulate settings such as number of flashes, frequency of flashes as well as some ‘slave mode’ settings and others that I’m non-too familiar with at the minute (I guess this might spur me on to learn!)I am really, really impressed with this flash gun. For the price, it seems to be a great bargain. I’ve added a couple of photos of the item and is packaging as well as a couple of photos taken with and without the flash gun attached.Overall, this is a great flash gun which I think is perfect for someone looking to add one to their set up, but with a low budget.

I was very excited to be asked to review this flash because as a family we are trying hard to develop photography skills. it seemed to be well made and well thought out. Then we panicked ! Would this damage what to us was our expensive camera? My daughter in law has just started a photography course and took the flash to her lecturer for advice. Advice was that was a very good flash a very good price. Her only criticism is that it was a little noisy when operating. My daughter in law is now happily experimenting and getting good results using flash with her Nikon 3200.Sent in exchange for honest review

It’s not often I use a flash as I tend to use mostly f/1.2, f/1.4, f/1.8, f/2.0 lenses wide open and with high ISO settings. But there has been times lately where there has been little light and I have found recently that a flash has been essential.I have not long owned my Speedlite by K&F and only used it on 4-5 occasions. I cannot be without it now and keep it in my kit bag at all times.When it first arrived like most things being inpatient like I am I tend to not read instruction manuals and most cases this is not the right thing to do. Well it completely surprised me that when I put the batteries into the flash and mounted it onto my hotshoe on my camera and turned the power on, the pilot button lit up blue indicating it was ready to trigger.I pressed the shutter on my camera and it worked immediately. My first thought was surely it can’t be that easy. I looked at the image on my canon camera. It was fantastic. I took several other shots. A few being over exposed. I quickly got use to being able to change the flash power settings both up and down. I soon got use to it…. taking photo’s of anything and everything around the house.This is exactly what I needed in a flash. Something not too complicated. It was then I looked through the instruction manual to see what it’s capabilities were.The Speedlight can be angled up and down 90 degrees and the head can also be adjusted left & right 270 degrees.I have learn’t how to bounce the flash using the different angles and I love this function especially seeing how shadows at different angles can change how an image looks. With the built in diffuser the flash is very versatile.I am knew to flash photography and I am enjoying this experience and I can honestly say that I feel my photography has gone up a step.There is a high speed burst mode which I have not experimented yet with. What I also like about this flash is that it recycles very quickly.It is a well made flash and comes with a free foot and a nicely made pouch protector. It looks and feels an expensive item. I am extremely pleased with it and believe it is very good value for money and I highly recommend it.
