I took RA40 wise advice and bought the above Ultra Wide Angle and it turned out to be an excellent addition to my APS-C only lenses and Sony a6000
The Milky Way at 10,000ft on Sonora Pass, Sierra Nevada, Calif. USA midnight; 8/8-9/15, 25 sec exp. - Rokinon 12mm, Sony a6000
Same 30 sec
I'll be working up an album to post. This shoot was an experience. I had never seen The Milky Way before. I had seen the night sky at 9,000ft at Bodie Ghost Town. That was like seeing a mill sparkling diamonds, now put an awesome Milky Way from horizon to horizon in to it WoW!
anyway the lens is very sharp ,Thanks RA40, This is the Best forum!
