iTTL works well with D60, it's a bargain

I had some success doing macro work but some of the challenges are getting handheld shots where a tripod isn't practical, light is low, or there's some movement in the subject. I took a chance and bought this and a Phoenix PZ139N and I'm quite happy with both. The RF46N attaches to the camera with a free-rotating knurled metal ring that projects beyond the edge of the ring flash. I thought you'd have to rotate the whole flash but in fact it's free-floating (rotationally) when the unit is fixe...

I had some success doing macro work but some of the challenges are getting handheld shots where a tripod isn't practical, light is low, or there's some movement in the subject. I took a chance and bought this and a Phoenix PZ139N and I'm quite happy with both. The RF46N attaches to the camera with a free-rotating knurled metal ring that projects beyond the edge of the ring flash. I thought you'd have to rotate the whole flash but in fact it's free-floating (rotationally) when the unit is fixed to the camera. Nice design though for all I know it's common -- I've never used another ring flash. Like the PZ139N, the iTTL works perfectly. I had to work to get a bad exposure. I did turn down the flash about 1/2 EV in my camera because I have the saturation boosted and the exposure was almost too much of a good thing. For instance, I photographed some red pepper slices and the red channel clipped even though the monochrome histogram said the exposure was good -- something I've had happen in outdoor light and even the internal flash with this camera so it's not just the ring flash. That said, I could photograph dark or light objects, closer or farther away and the flash and the camera worked together to control the exposure. Unlike the PZ139N which has a convenient exposure compensation slider on the back, the ring flash has no controls but an on-off switch. However the flash exposure compensation in the menu of the D60 does control the light. As noted, this thing is super lightweight and that could be a concern if you shoot under demanding field conditions. Being just an amateur I need to control cost more than I need battle-worthy durability. That seems to be it's main detraction. Functionally it's sound. I shoot with a Quantaray (Sigma) 50mm F2.8 macro lens. With short focal length macro's like this, your working distance is quite short. When you get close enough for 1:1 the flash is almost touching the subject so take this into consideration if you shoot short focal length macro like I do. This thing would be killer with say a 105mm macro -- but I still like it and can use it. It doesn't lock to the Nikon hot shoe with a pin. It uses the standard threaded ring retainer that many inexpensive flashes use. But it fits securely and the contact pins seem to help retain it also. There's a distinct "detent" feel when you slide it on or off the the camera. I got it on sale here at Adorama and substantially off the normal price listed above -- but I conclude this would have been worth the normal price. It's really a high-functioning bargain and the iTTL implementation works well. I'm happy as I've heard of other so-called iTTL compatible units that don't really work well.

Too good to be true

Excitement didn't last. Once opened, it didn't work with rechargeable batteries, it didn't work with Lithium batteries and it didn't work with Alcaline batteries. Camera (D300) recognized there was a flash mounted but did not fire it.[...]

Serves my puposes.


from Arlington Heights, Illinois  -  Semi-pro Photographer

I do a lot of Macro photography and prefer available light, but sometimes that's impossible. Without spending a fortune you can have this flash that works very well. A lot of reviewers complain about the quality, but it's not bad at all. If you treat your equipment with care and respect you won't have a problem. Very easy to use. If the flash is too bright you can use your camera's flash exposure compensation to tone it down. I'm really happy with it. I use it on my Canon 100mm Macro and get great images. The only thing I wish it had was a rechargeable battery, like my camera. Other than that it's great.


Dont Waste you money


from Wisconsin  -  Semi-pro Photographer

Received a defective product. The product didnt power on for the first time. Battery compartment is too tight and had difficulty in adding and removing battery.


Tremendous value!!


from Corpus Christi, TX  -  Semi-pro Photographer

I just used the flash for the first time two weeks ago and got great results with the flash. Very impressed especially with the price I payed in comparison to others.


Great Value.


from Cherry Hill, NJ  -  Photo Enthusiast

Is this a very light weight flash, yes. But what do you expect at this price point. You have to handle it like an inexpensive flash. It does perform, however, like a flash that costs three times as much. I use it on a D300 and it gives me full TTL exposure. I have also used it maually with equally good results. I have it mounted on a Nikkor 105mm G lens and I am ready for any macro situation I might encounter in the field. As a bonus, the power cord from the flash to the flash shoe unit is long enough that you can hold it off lens for side lit shots showing more texture or detail.


Nice flash for the $


from Cincinnati  -  Photo Enthusiast

Looking forward to warm weather to try it out on bugs and flowers. Seems to work well. Had tried a ring light, but but did not provide much illumination. This ring flash actually has pretty good output.

Great flash weak connector


from YORK,PA  -  Pro Photographer

Handle with care. Great flash but the hot shoe connector is weak, eventually shatters and I am on my second one. Still cheaper than Canon by a mile and when it works it is great. The less you have to put it on and off the camera the better. You can buy 5 of these for the price of one Canon ring flash and mine lasted for a year of hard use before it fell apart.

Fun to use, not fun when it breaks


from Brooklyn, NY  -  Photo Enthusiast

For the price and performance this is a very good unit. However, the power switch is a very cheap part that sticks up above the case and is easily turned on when you put it into, oh, say, a pocket on your camera bag. Where it is left on for a couple of weeks. Which isn't good. OK, OK, my fault, yes, and my fault for waiting so long--over a year--to seek out a repair. Turns out a major photo repair place in NY can't repair it, and the distributor would have replaced it if I had returned it to them within the warranty period, but they don't have any parts and won't try to repair it. Now I have a ring flash that I used exactly once that is yet another plastic piece of garbage. Why can't we fix things anymore??


Awesome flash


from CENTRAL WI  -  Semi-pro Photographer

compare cost from Canons macro flash line, this one is a no brainer under a hundred bucks ETTL controlled


Kind of cheaply made


from Miami Beach  -  Semi-pro Photographer

Had to mess with this since the connection didn't always result in a flash.

Well worth the low cost


from Albuquerque NM  -  Photo Enthusiast

Use it for maro work where power is nt an issue, although it does fine within its range. TTL lets the camera do the exposer work - nice. I had to lubricate the attachment wheel as it was quite sticky, used a silicone based lube and OK now.


Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Will this macro ring work on a canon g16 using the adaptor that can be bought for the camera?
DAVID S  From my research I'd say no, it won't fit on any auxiliary lenses that I saw. Doesn't mean There aren't any though. As far as the E-ttl, it should work just fine. The only thing that may not work is physically attatching it to the lens but if you know of an accessory with threads that are this size it should work just fine
L U  How many flashes do you get out of this?
CHANNING P  I didn't use it long enough to find out. It's too flimsy for my use and I purchased the Nikon Creative Lighting System after one short session with the Sigma.
Shopper  I have a nikon D300 and f 2.8 70-200 lens which has a 77mm lens. Is there an adaptor to fit the Phoenix Ring Flash for this Nikon Lens ?
Ragnar A  Yes, this does have several adaptors
