Not sure what lead you require, see the common shutter release leads page. Still not sure? Drop me an email.

Normally a coiled lead 30-100cm.
I sometimes have limited stocks of non-coiled 1 metre leads which will be used when available.

This is a DIY kit and requires assembly. You should have at least basic to middling soldering skills and of course soldering tools. Please read through the construction guide so you are aware of what is required before purchasing. I do not recommend this as a first soldering project.

The main components are fully tested but due to the nature of the kit I cannot fully guarantee it. There is a lot of possible user error!
