Haydin - I note that you are a relatively new member of this site, and this thread alone should demonstrate its value. You got a broad range of opinions and observations, all offered with courtesy and thoughtfulness. You simply don't see the "flaming" here that too often characterizes other sites, or anyone suggesting someone has obtained "too much camera for their level of expertise." The monitors won't permit it and 99.9% of the rest of the members self-police it. This is a great place to bring observations, questions and ideas. We all gain from the resulting dialogs. It is absolutely true: there are NO dumb questions. None.
