Вспышка KF570 II для Canon Nikon с одноконтактным башмаком

First off this flash is not for the lighthearted, by that I mean it's on a par with some of the more professional units I've used in the past. Its colour temperature rating is spot on, and at 5500K it is certainly bright. the flash recycle time is about a second quicker than 2.9 seconds quoted by K&F, which can only be a good thing. The flash itself is exceptionally bright and I would heed the warning in the front of the manual. It's more suited to bounce flashing than direct (see the pics from a church). I would not use it as a direct flash on anything other than commercial photography of large subjects, and on a pretty fast flash speed of 1/128+ at around 1/500 sec exposure. Although there is a lambency diffuser supplied I found it a little too thick, but in a near total black shoot It would certainly soften the flash.The slave characteristics are great, no issues coupling with my Nikon D300. I popped outside and placed it at the foot of an Acer in my garden, stepped back 10 meters and set it to 1/64 and the result was none too shabby.The tone or voice prompts are clear and unlike other systems are specific to the needs of the flash, not just generic noises that leave you guessing for hours.Overall the flash is a great piece of kit and whilst its bigger than most, it packs a punch that belies its size and doesn't drain rechargeable batteries rapidly either. It comes with its own case and slips into my camera bag very easily. The hotshoe action is crisp and the pins haven't stuck as yet, which is always good news. 10/10 for ease of use and ergonomics. Another great piece fo kit from K&F Concept.

 My hobby is photography and trying to get to every area of the photography. This speed light is perfect for studio or outdoor shooting in low light.Arrived in a cardboard box with a pouch, a mini stand and a very good, useful instruction manual. I have a Nikon D5100 camera so this speed light is perfect for that.It needs four AA batteries what the package does not include. It can be used attaching onto the camera or it has its own mini stand what can sit on any flat surface (table). It connects by hot-shoe to your camera or stand.At first attach the speed light to your camera or stand, make sure will not fall off. Under the LCD screen (big and visible) there is the ON/OFF button. Turn it on pressing it for few seconds. It has a self-secured system, what means if the speed light is not work for more than 30 minutes it will shut down automatically.You can set manually the brightness of the flash between 1/128 and 1/1 it depends your own requirements.It can be used as a slave too with the same bright settings (slave means camera off light; it is triggered by a built-in camera flash, a trigger or any other flash for that matter).- S1 mode: this is suitable for manual flash environment what senses every flash and synchronous main flash but cannot be used with pre-flash TTL flash system.- S2 mode: this mode ignores the pre-flash TTL flash and synchronizes with the main flash.- multi mode: it can provide you stroboscopic flash mode. You can set the flash frequency (Hz) what means number of flashes per a second). Do not use this mode more than 10 times because may overheat and damage the head.The head zoom can be set too, the value in mm.You can set the voice prompts as well, it can be turned off or on. If it is on, depends on the meaning, it gives different rings so if you learn them you can recognize easily what it want to "say".The flash tilt is rotatable, depends on your own requirements.The amount of light is adjustable by using- the built-in white reflect board (make the subject more brighter)- the built-in wide diffuser (when the distance is less than 2 meters)- the built-in white reflect and wide diffuser at the same time- lambecy (package includes).Overall I highly recommend this flashlight, I am happy with it and say is really worth the money.

Very pleased

Great pics on manual mode. Compatible with Canon Eos 100d; very happy about aqisition.

So fare so good. Feels a little cheap, but still extremely great value for the price. I'm a complete casual user, really only using it for the occasional event where some friends and family are over. TTL works great too. Currently using it with EBL NiMH rechargeable batteries and its not noticeably slower than any other AA batteries (except when the charge gets low). With that said, because I'm not pushing it to its limits, I cant really speak to overheating issues that might arise from prolonged use. TL;DR: great for casual use

Works well and is a superb product

Owning a Sony camera, I didn’t want to splash out on their extortionate TTL flashes, so I opted for this manual speedlight (the KF-570II), and I’m glad I did.When turned on for the first time, the display said 1/128. That means it’s flashing at 128th of its full power: once I understood that and pumped the power to 1/1, it was crazy just how bright it was.It’s a manual flash, so you need to have your camera on manual and experiment with exposure to get the right results. Set your white balance to flash, for a start!I’ve really enjoyed getting back to basics and feeling like a proper photographer with this flash, and really thinking about lighting: as I work in film, I tend to use film lights for my photography too, so it’s a challenge to visualise how an image will look taken with a flash when it’s not on all the time.This one has a motor inside to move elements about depending on your zoom range so that you can go from 18mm to 180m.My Sony needs to have a shutter speed of 200th, otherwise I get a black line halfway down the image: some flashes let you go to 800th, I think. One important thing to remember though, is that shutter speed is almost removed from the equation when considering exposure if you are using a flash: the burst of light is so fast, that whether you use 1/200 or ¼, you will likely get the same exposure as the flash only lasts 1/200th of a second.If you are in a space with strong ambient light then of course, a longer exposure will result in more light from other sources, or an image with a bit of artsy post-blur, but be careful when mixing light sources that you don’t end up with orange or blue casts.Playing with the flash power, ISO and f stop you should be able to get perfect exposure, and using the angled head to bounce light or use the attachments to soften it, you can get some very flattering shots indeed.One big plus: in the description it says you need to let it cool for 15 minutes after taking 10 flashes. I thought that was mad, and it’s not true: that is referring to an option it has to flash 10 times in a split second to get a series of shots if something is moving past you quickly, which would all end up on the same shot (such as a BMX racer doing a jump - you’d get the bike at 10 points across the same photo). Besides that quite specialised use, you can flash away merrily as often as you like and not worry at all about overheating.This is an awesome piece of professional kit, and with a digital camera to check exposure and perfect lighting, this can only make me a better photographer.

great for the price

Great manual speedlight works well for me great price

Excellent flash speedlite which I purchased for some low/high key photography. I have a high end one and this although not built as well for the price produces very similar results. I use this with a remote .. very happy with this Flash
