The Pico Flex Dolly is a miniature dolly for DSLRs. Ideal for table top product shots where the camera is inches from the subject. It’s on the 4 wheel two axle design like the earlier SpiderTrax Dolly which was designed and built by Emm of cheesycam.com. It’s $65 for pre-order from http://photographyandcinema.com. The latest shipment is due in soon.
When filming with a DSLR from inches away, focus will be critical. The Pico Flex Dolly can be set to run in a precise circle around the subject and this should help keep focus constant. Aside from tabletop photography for product shots, you could dolly sideways framed on subjects further from the table.
