What the thread found

• The RTMotion MK3 receiver is notably compact in size compared to competitors.
• The system includes digital capabilities and lens mapping functions under development.
• Build quality and motor strength are reportedly lower than Preston systems but acceptable for the price point.
• Wireless range through obstacles like walls may be limited compared to Preston systems.
• Some users reported significant lag between handunit input and motor response, though others experienced none.
• Motor torque may be insufficient for older or high-tension lenses.
• The handunit tension can feel loose but may be adjustable.
• Hocus Products was developing an Axis1 system for a similar market position.
• The Axis1 system was reported to feature no lag, fast response, quiet operation, and solid build quality.
• Direct ordering through RTMotion.com was the primary purchasing method with significant lead times reported.

Depends on

• One user's experience with lag in motor response could have been specific to their unit.
• Comparison with Preston was noted as potentially unfair due to significant price differences.
• Limited field testing data was available at the time of discussion.
• Only one unit was tested extensively for wireless range through obstacles.
• Motor strength testing was only conducted with relatively easy-tension lenses like Optimo zoom lenses.
• Axis1 system information came from developer claims rather than independent testing.
• Geographic limitations noted for Australian users in accessing demonstration units.
