Autofocuser 2

Listening to your feedback we developed a next generation autofocusing unit with WiFi connectivity and optional accessories - wired hand remote controller and temperature probe. Now even manual focus changes using your mobile phone/tablet are so simple that even a toddler can do it (check our Youtube channel for a demonstration on a prototype unit). At the same time it is also retaining mounting compatiblity with our older units, so upgrading to AF2 is as simple as swaping the units - no need to change mount adapters or belts.
