Quintuplet Petzval with two SD elements, 85 mm aperture, 408 mm focal length (f/4.8), 44 mm image circle.
Ordered in advance for holiday to experience the eclipse in August. The 10 pairs of glasses came loose in a large envelope so I will put them in a cloth bag or something to prevent scratches. Good value and efficient, helpful customer service when I messaged for advice before buying.
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.
