Yes, they can be useful in phootgraphy other than macro. A 'ring light' (usually one of the more larger ones) is occasionly used in portraits, due to the soft and even way it illuminates the subject and provides circles catch lights within the eyes. (As the light is central surrounding the lens, it reduces shadows usually caused by lighting position). It ...

The first thing you want to do is to check that the pins on the foot of the flash match the contacts on the hotshoe of your camera. They need to match in both the number of pins and placement so that the pins will touch the contacts exactly. Most sellers will show a picture of the foot of the flash.

Here's a link to Neewer's website. I did a search for the VK750 ii and this was the only flash shown: https://neewer.com/?s=vk750 Apparently, Neewer has given this Nikon-compatible flash its own unique model number as the one for Canon has its own unique model number. Generally, this is how you can determine if a flash is for your Nikon: Since each ...

The Neewer VK750 II is very compatible with the Nikon DSLRs (iTTL, in the last ten years), including the D3400. This Neewer VK750 model appears to be a relabeled Meike MK-951. It is a good choice and a good flash, however, it is not one of the fully powered flashes (like Yongnuo for example), but it is comparable to the power level of a Nikon SB-700 ...

Any suggestions/solution? Test fire the flash to make sure that it's able to fire at all. Replace the batteries in the flash with fresh ones. Check both the hot shoe and the foot of the flash for dirt or corrosion. Even if you find none, you can rub the contacts with a pencil eraser to clean them a bit. Check the fit: is the flash fully seated in the hot ...

I don't have a Metz 52, but in the Manual for the Nikon version, on page 167 it begins with an English description of its use with Nikon Advanced Wireless Lighting mode (AWL is the wireless optical control component of the Nikon CLS). Some Metz flashes with AWL (like AF-54) can only be a remote slave AWL flash, but the AF-52 also describes that it also ...

In addition to portraiture - where one can be used as either a key light, a fill light, or simply a catch light - ring flashes are often used in forensic photography, both at macro and non-macro reproduction ratios. Then there's the whole "Jarvie" window thing or even using it in the scene as a compositional element.

I doubt there'd be a generic SU-4 type unit, given that all you have to buy to duplicate the function of one is a "dumb" optical slave that can connect to the SB-25's PC sync port or hotshoe, such as the slaves from Sonia or Wein. The very inexpensive ones probably won't ignore an iTTL pre-flash like the SU-4 mode/unit does, but then the SU-4 doesn't ignore ...

There's a Debao SU-800. Looks to be about $100, and more powerful. fstoppers.com has a review.
