Main improvements of the 2nd generation of EF-FX Pro include
- Redesigned aperture ring for more convenient operation
- New MCU (more powerful, more resources for firmware update)
- Better light absorbing design
The functions and performance of gen1 and gen2 are the same.
So far only the EF-FX Pro II is released. The non Pro version is still the first generation. In the future, the functional firmware update for gen1 and gen2 will be released at the same time as long as the resources of gen1 are enough to support that.
The Fringer EF-FX Pro II is open for pre-order now. Please visit my web store to purchase it.
