What should I look for as a remote activated intervalometer? I am interested in experimenting with time lapse and interval photography.
I use a canon 550D.
I have briefly experimetned with the Hahnel Giga T Pro II. This was interesting but I had very little time to try more.
I don't know how fancy you want to get, but the one you mentioned has many features than I ever needed with my intervalometer.
It seems to me that if you don't know what to look for, your needs will be pretty simple, like my needs - you just need to take photos on a predefined interval. And I think almost all devices will satisfy this need perfectly.
One feature that I like is the ability to manually release the shutter 'during' an automated session. I found it useful when I wanted to include more photos of a particularly interesting moment during making a time lapse of a trip.
SO if it is not the set of features, what else is important?
Battery life - most devices offer satisfactory battery life, but on a remotely triggered model it may be shorter than on a cable model. Can the batteries be replaced? What size does it use? How easy it is to charge / replace batteries?
Quality of build. Are the contact points metal or plastic? Are connectors solid and will they not break due to frequent use?
Does it get a lot of bad reviews online? Are there known issues that people frequently report?
Make sure you are not paying too much for a brand model. I use a cheapo intervalometer that I got for ~$30 bucks and I have made many time-lapses with it. It never failed.
You may want to consider the Camera Axe, its far more than just an intervalometer and not too expensive.
You can use it to trigger based on time, or an event such as a sound or lightning bolt.
