I have two 203mm f7.5 lenses and would like to sell or trade one to buy a new lens with shorter focal length for landscapes. I have had the Ektar lens serviced and converted to work with my studio strobes. I think it’s a decent lens for portrait, table top and macro work in the studio. It’s a bit soft at the edges wide open but I haven't done any movements on it yet. I’m thinking this is the one to keep but have no experience with the Optar and it needs CLA. Which one of these lenses do you all like the best and if I get rid of the Optar should I have it serviced first, or just try to trade or sell as without being serviced?
