Query: Good timed exposure tool

This has two main advantages over the cordless remote: you can stand anywhere you want within the cord's limit, and you can use the shutter release lock to hold the exposure without tiring your thumb.However, the lock can be accidentally engaged if you have fat thumbs like me, so it's worth being careful. It's also worth noting that connecting the cable can jolt an already framed shot, as it takes some oomph to push it in.Overall, a well constructed unit, but be careful with the shutter release lock.
