Beware, if you buy one, you'll find out it is "for everything".
Not really though, since the 105 does not do close-up shots. That's the limit maybe.
Concerning the backlit stuff, please consider that the "Praia do Molhe" shots were minimally processed (no attempt to enhance contrast) ; the organ shots received "my normal" processing using LR (some noise reduction, some re-balancing of highlights and shadows...), excluding extreme measures such as HDR or fringe suppression.
