In case you were thinking about buying a DFocus follow focus for your 5DMrkII, you might want to wait a few more days. I am not saying this because of any quality issue with the product (you all know that I love it) but because of a teaser picture Dave posted on Twitter.

This new product is called the DFocus Pro. It will include a better gears system and be upgradable from the current version. An official announcement should be made in a few days.

By the way, if you are interested in any of Dave products, you should follow him on twitter. He always tweet about incoming products and stock levels.
