Perfect add on for easy alignment using an iPhone.
This lens is excellent in my honest opinion.
Round stars in all 4 corners even with full frame sensor and no weird shapes either.
It even comes with kit (belt and pulley) to install your EAF. Easy set up, light weight and it looks pretty cool in black and red.
Highly recommend.
I would also recommend Dark Clear Skies as they have dispatched my lense on the very first working day, and it got delivered the very next day. Just in time for some clear skies and first light.
Over all excellent experience with lense and family run business too. Huge thank You.

Paul has been absolutely astounding in his support with regard to purchasing this camera, and I could not have asked for more! Highly recommended. Thank you...
