5D MKII with 24-105 F4 L IS / No Sound.
First test of home made dolly system.
Please forgive any sudden movements as that is the user and not the dolly itself.
I still need to design and create the tracks along with a wheel lock system to prevent the castors rotating.
It's a pretty cheap solution which allows full movement, great height adjustment, portability and 360 degrees of rotation.
It's perfect for an amateur enthusiast without spending a huge amount of money whilst still retaining a respectable level of quality.
