Snarfy, valid point. I thought of including context in the original post but decided to wait for fear of writing an essay..
I shoot lots of macro and while I enjoy the proximity the 100L allows..I'd love to get even closer. From what I've read..extension tubes don't make much sense given I am already SUPER close to my subject (the exception being flowers or any subject unbothered by a camera creeping in) and decreasing my minimal working distance would only cause problems with insects and natural lighting. However..I haven't used extension tubes or tele-tubes so I may not be covering all the bases.
I shoot landscapes, portraits/group shots, detail and just about anything. So my main goal at this point is versatility. I like the idea of tele-tubes for that reason but my question comes in which one is the right choice. As for my budget.. I'm not interested in switching to the 180L macro and would like to stick around the <$250 range.. for the teleconverter or extension tubes. Would 1.4x work well with an effective focal length of 160mm or would 2x be better? Loss of a half or full stop isn't of much consequence since I max out at 2.8
In regards to your other questions.. "The 28 1.8: is a 45mm normal lens a good fit for you? Do you need to have 28mm covered 3 times?" That's my point exactly..I don't think I need it covered 3 times..I just want opinions on whether the 28mm and 18-135mm are worth holding on to if I have my sights on a 24-105mm (or something in that range) eventually..
"24-105L vs 24-70L vs fast prime(s): Do you value image quality or convenience more?"
- I think I'm more keen on image quality but that's not to say one can't have both in the same lens. At this point I think a zoom would be more realistic.
In regard to various flashes..I'd prefer to keep with Canon but at a price range around $270 aka..the 430EXII on
B&H. ..I'm not willing to spend an extra $200 on the 580EXII at this point... Question: Are there other options that offer the control of the 580EXII..slaving but at a price more near to the 430EXII?
Thanks for taking the time to ask the questions Snarfy!
crbeveri, thanks for the advice and the link! Coincidentally, I recently read that thread, thanks for bringing it back to mind!
Hopefully I'm not contradicting myself or being too redundant. If I am, please forgive me, just came in from working out in the garage and this 100+ heat doesn't help to focus my thoughts.
