goodbokeh Posted August 19, 2023 Share #1 Â Posted August 19, 2023 Advertisement (gone after registration) I've been doing research on the APO SL 50/2 lens for a possible future purchase. I can't find any mention of how well it does wide open with coma on point light sources like urban street lights or a star field. Does anyone have a link to such a report or have a relevant photo they could share? Thanks, Doug 1 Link to post Share on other sites More sharing options...

goodbokeh Posted August 20, 2023 Author Share #4 Â Posted August 20, 2023 Thank you Eclectic Man. A picture is worth a thousand words and that is a very fine coma performance in my book. Link to post Share on other sites More sharing options...
