I shoot mostly primes 15 to 100mm.
I have the 55-300 to but really only take it if i know i'm going to need it. ie going to the Zoo, or (planning to go see some motor racing this weekend, hope the light is good, I don't have the time or money to find an FA*300 2.8)
When chasing around your family or a photo group its a bit more diffcult with primes. Next time I go on a a family touring holiday i will use this as an excuse to get the "approval" to buy a decent wide-normal zoom.
Maybe I'm really a zoom shother that only carries primes.
I recently went on an outing with my local amatuer photo group for a walk around the historic areas and docklands in Sydney. Most of the group have Canikons with 18-55 50-200's or 18-270's.
I turn up just for some fun with only a DA15 and DFA100, my 2 current favourites.
In about 3hrs I changed lenses 18 times!!! It seemed I always wanted "the other one" and I was always chasing the group from location to location.
The guy who leads the group is a pro with 40years experience, does weddings and runs DSLR courses. I was stoked when he turned up with a 50mm/1.4 but alas, 20 minutes later he says "just can't do this" [with the group] and snaps on an 18-270.
Anyway after the shoot, we give him 10 images for viewing and group discussion. Later he told me that he was really impressed and I got some brilliant shots. I'm not sure they were that great but maybe the lone Pentax shooter was just different to everyone else.
Pentax.... be interesting
