Thank you Dan, will appreciate you forwarding me the link. I'm now at my forth year (last one hopefully) of my B.Sc.EE degree, intend to take few optical systems/lens design courses next semester to grasp in-depth understanding of physical optics and photographic optics in particular. That may not necessarily make me better photographer
, but I like gaining solid background and understanding of the things I'm interested in, including any scienetific comprehention as much as I can "swallow" given the knowledge I'm gaining during my EE study.
PhotoPete: thank you, that scores favorably towards Sidney's book.
Ole: you advise is appreciated as well. I'm aware about OSLO, and even managed to take a look to the evaluation version once, however at that time (3-4 years ago) I didn't have the necessary background to make myself comfortable with it, neither had the formal math base necessary to grasp optical design approaches. I certainly planned to get into it (and some of the optical desgn courses I intend to take deal with OSLO), but first gaining theoretical understanding will not hurt...
