In price comparison to the Nikon ML-L3 Remote Control
it's a bargain.
The remote is just taller than an AA\AAA battery and considerably thinner. It features just one button that will auto focus AND shoot.
The remote arrives without any instructions. The following steps should get you going:
1. It comes with a coin battery (a CR2025) already in the remote. Remove the small plastic film from the battery's housing to get power flowing. Incidentally there is no light to indicate the remote is powered on.
2. With the remote now on, go to your camera to change the Release Mode. On my camera this is done by pressing the i button and scrolling down to Release Mode. Change the setting to Quick Response Remote or 2s Delayed Remote.
3. Give it a few seconds and that should be it!
Tips, concerns, suggestions:
1. This remote (and the Nikon remote) can't wake up the camera so there is still a good chance you will need to bring it back to life by pressing the shutter button on the camera. This would be a pain if you were constructing a scene but you improve this by changing the "Remote On Duration" within the Nikon's menu system (Timers/AE Lock) from 1 minute up to 15 minutes.
2. You can't flip the battery over when not in use as the casing won't fit back in to the remote but batteries are cheap at £3 for 12 so should only be a minor concern.
3. In relation to the above, if the camera does go on standby, it will end up changing the Release Mode to whatever it was previously - most likely Single mode where yo physically pressed the shutter release button.
4. The auto-focus modes will have different options in this particular shutter release mode - worth checking to see what impact it can have on your shots!
5. Once the camera auto-focuses it will take a shot, you can't just focus the lens only.
6. Use the camera's Live View so you can take a look at your subject without peering threw the viewfinder to check the composition, but Live View does consume a lot more power.
Despite the few shortcomings - which may in fact be Nikon's responsibility - this is a very convenient and affordable piece of kit that will most certainly come in useful for those shots where having to press the shutter button isn't the most ideal.
