Triggertrap MD-N3 Mobile Dongle 2 for Canon

What more can I say, it does what it promises too and does it very well. Bought to work with an iPhone 5 and Canon 5d MKiii and no problems to report.

I have been using this product with the iPhone 4S and the Canon 5D Mark II; I was able to download the app for free from the store.For £25 the box doesn't come with much in it, a few simple cables the connect to each other, and then one side plugs into the phone and another into the camera. The build, to be honest, also doesn't feel that great.However, I do think the price is reasonable for what the product offers.I've been shooting HDR images for several years and using a couple of Canon cameras I've been limited to only having 3 brackets during that time, unless I've been using a tripod and manually changed the exposure compensation for the bracketing, or using other accessories to get around the limitation. Likewise for time lapse or star trails, I've been using accessories of various kinds to be able to plug into the camera as and when I need. As such, as well as my camera I often carry around a little bag full of assorted cables, several trigger releases, an intervalometer, and also the Promote Control - all of which I use for different scenarios depending on which is required to make the job easier. This device means I can extend my brackets, I can use it as a trigger release and I can use it as an intervalometer all in one, with a small number of wires and a phone which I always carry around with me anyway. That's a lot of room saved in my camera bag, and could also be a lot of money saved (the Promote Control alone was £200).I found the product very simple to use, simply install the free app on the phone, connect the wires to the camera and phone, set the camera to bulb mode and away I went.There are some features I'm sure I will never use, such as the noise shutter release, or the one based on magnetic force or something. However I do certainly use it for extending the brackets I shoot for HDR where the range requires, and the settings for both time lapse and star trails. These ones are the important ones for me, with the rest being novelty settings.It's a simple device with a functional app, and compared to other products on the market I feel it offers great value for money.

If you haven't tried it or heard of it the trigger trap app is the camera app that Canon should have written. Trigger trap can do all sorts of clever smartphone enhanced photographic timing functions like taking a photo every 100meters using the phones gps to map it out; or take a photo when someone moves in front of the (phones) camera as well as all kinds of time-lapse functions. Unfortunately triggertrap won't connect to my 6d using the camera's built in wifi so you need a control cable to use it. The MD-N3 cable is for the /professional/ style canon shutter release cables. You connect to your phones headphone socket (dialling the volume all the way up) and to your camera; then set the camera in bulb mode and you are away.The cable is a cable; the world it opens is fantastic fun. The App is free; 5*.

Worked when I tried it out of the box then went out to do timelapse and it failed completely. Havnt tried it since. I was using it with android.

OK, I've been thinking to get one of these from many months and always the steep price has stopped me. Recently I've decided to grab it. I'll try to summarise what you can and can't do with this:You can:- take single pictures- take timelapse pictures- take bulb pictures (actually most of the functions require you to set the camera in Bulb) in two ways - "click and hold" or "click and click"- activate shutter by sound - snap fingers or clap will do the work- take long exposure HDRs - meaning 1/15 sec shutter speed and slowerYou can't:- hold your finger to take burst of photos (even if they happen to be at 1/15 sec or slower)- take HDRs in daylightIt seems that it can do more than it can't, right? However, for a ~25 GBP remote trigger, which actually needs another device to work with (iPhone), this is more than too much. Especially when you open the cheap small box and see the little red cable inside. The connectors seem to be gold plated, but they are a little bit flimsy and may break after some time.Here are my pros and cons for the cable itself:Cons:- very short;- regular cheap quality cable.Pros:- depending on your tripod, you could leave the phone to hang in the air while taking long exposures. This is either good or risky depending on one's point of view. IMO, it is actually very good, because as I mentioned in the cons, the cable is very short and you can't just stick the iPhone in your pocket (you could to it only if the camera is about your waste level);- small, doesn't take much space, will fit jeans pocket, but I guess it won't be very comfortable for everyone.To summarise, one should really think through if he prefers to carry a regular remote trigger with fancy options for around 10-15 GBP, or instead buy this cable for 24 GBP and have to stick it in their iPhone..The best feature is the Long Exposure HDR, which is good for taking HDRs during night time. I usually shoot larger aperture in order to reduce my shutter speed below 30 sec. Now with this cable, this is no longer a problem. I just have to find the Middle exposure (set in Aperture priority mode, set desired ISO 100-200, set aperture and check what is the shutter speed given by camera), then input it in the TriggerTrap app, and select the Number of exposures (3-5-7 is normal) and EV step (1-2 stops), then press the big red button to take the exposures. It may seem like a lot of words, but in reality it could be done in 10 sec.All in all, I am taking one star for the limited functionality and one star for the price. I usually don't take stars for price, but the product should be worth it and I can't say positively this one is...

The system works very well and although I haven't really had time to give it a good run I am sure it will be OK. However, the cable connection on to the camera (Canon 5D MKIII) is not too clever. The connection is rather loose, which appears to be caused by the quality of the plastic conector. We will see how long it lasts, I suspect not too long....
