Question: I see this is mounted in front of the camera rather on the hot shoe. Does this pose a problem shooting or covering some of the functions?
Document: The knurled ferule knob is a slightly oversized to make tightening process easier for those of us who don't happen to have delicate little fingers.The receiver antenna is made of a soft flexible rubber to prevent damage, and when the receiver is mounted to the camera, the antenna sits just slightly below the hump of the D800 integrated flash. NICE! In fact this receiver mounts so unobtrusively, I left it mounted to my camera during a recent all night shooting excursion through Chicago and had no problem with it. I love the fact that this thing has no dangly cable nor does it require you give up your hot shoe.The receiver which draws its power from the camera (no batteries needed for the receiver) also has a two LED lights, one that glows red to confirm the receiver has power and one that shows blue to confim a shutter activation in progress.The transmitter is a sturdy built unit that takes a single AAA battery (not supplied).
I can see the antenna snapping easily against the neck strap if you sling the camera around with a heavy lens attached. That said I'd much rather the antenna snap than be sturdy enough to torque the whole receiver enough to damage the camera body port and SMDV seems to realize this too.My only other note is that on a D800/800E the top of the receiver body sits right next to the flash release button. I can't really imagine under what conditions this would be a problem except if you're shooting hand-held eye-to-viewfinder and suddenly need to pop the flash, and at that point why do you even have this thing attached?
Sometimes I want that spontaneity after shooting a delayed shot, so an extra option of the handheld remote would be great. But with my current remote going on the hot shoe (and then there's the GPS that ALSO needs to go on the hot shoe) - it's a difficult call.Regardless, it's a great device and a definite item to keep in your camera bag (or always on the camera). 5 stars!
Like this product so far. Great design because: (1) receiver attaches to camera body (Nikon D3), not the camera's hot-shoe, so you can use it with your flash attached to camera!! !, (2) receiver uses camera's power, so no battery to buy!! !, and (3) transmitter uses only one AAA battery [not some hard-to-find battery]!!! I use this mostly for shooting with camera on a tripod & slow shutter speeds with camera's mirror locked up.
This is about the forth remote I have purchased over the years for my Nikon cameras. The RFN-4s has set a new standard for remotes. The unit mounts directly onto the connector and not the hot shoe allowing use of the built-in flash or a mounted flash. All other remotes have failed on me. So far this one is a survivor. Great product.
Pros- not as cheaply made as expected- auto focus when 1/2 pressing the shutter release- high hit rate for firing- good range- fits in the 10 pin connector and doesn't interfere with the hot shoeCons- you pay for the pros aboveI am not a professional photographer, but rather a serious hobbyist, and this wireless remote fits my needs very well.My favorite features, in addition to the range and performance, is that you don't have to have a direct line of site to the receiver from the remote, and that the receiver fits into the 10pin connector instead of the hot shoe.I am now able to get into family pictures on vacations.
I have my own remote for the Nikon D300/D800 that I have been using for years (via EBay). The biggest problem is that most of these remotes attach to the hot shoe (or you rig them to wrap around your strap). So hearing about this one, I bought it as a gift for someone's Nikon D2x (and that way I got to try it out as well! ).It's excellent!Keeping the hot shoe free and having it attach as 'part of the camera' is a smart idea!
I have used several different triggers on my &#34;Take Your Own Photo Booth&#34; that I set up at weddings and parties. This is absolutely the best, with one caution... If you need to use the PC Cord outlet, you cannot use this item because it screws into the 10 pin connector and the antenna obscures the outlet. I don't have the problem because I use a hot shoe PC outlet or a Pocket Wizard. This unit is flawless and survives dozens of drop kicks by little kids and clumsy adults.
The deal breaker is this: the receiver that is attached to the camera is rather thick. After its completely plugged in snugly it stands away from the camera's body 3/4 of an inch. That's fine if you do not have a big lens mounted. I have a Tamron 24-70mm F2.8 lens I bought just for portraiture and it was this lens I wanted to use this remote with. When that lens is mounted you cannot put the receiver on without removing the lens first. And even then as you turn the lens into position the lens hub then pushes into the receiver and pushes down on it,  as the lens clicks into place.
I literally popped the battery into the remote and connected the receiver to the D800E and that was that. Done. It worked. Beautifully. Auto focus, release, bulb mode, everything just worked.That said I noticed another reviewer commented that they managed to break the antenna on their receiving unit although it didn't impact functionality. I can see how this would be possible as the receiver antenna plastic feels somewhat fragile. The actual mounting screw for the port is steel and is very sturdy but given the perceived frailty of the receiver antenna you should only leave this unit attached to your camera body when it's mounted to a tripod or otherwise not slung over your shoulder.
Answer: I use the remote on my D800 and have no problem with access to the controls.  It makes for a bit of a tight fit related to the flash button and is close to the lens release and left dial that controls some of the settings like quality and bracketing etc.  All are still accessible though.  As well given I am taking remote pictures I will have the time to ensure proper settings are selected beforehand.  This remote is excellent and cost-effective.  Used it on safari with mirror up to minimize shake and vibration with long zooms.David
