240mm goerz red dot artar f9/ 180 mm apo sironar sgreenspun.com : LUSENET : Large format photography : One Thread
Hi all, Just wanted to get a few opinions on these two lenses.How is the 240mm f9 red dot apo artar image quality at closeup, as well as at infinity and image circle size at infinity? And the same for the rodenstock 180mm sironar s. There seems to be a lot of info about the 135mm and 150mm sironar S's but not the 180mm.Is the 180mm a lot bigger than the 150mm? And how is this lens for 5x7? Thanks a bunch!
