Originally posted by dansamy My niece complained about the weight of my photog backpack. It *only* had a K-5ii, da*16-50, da*50-135, DA 35, DA 50, AF 200 FG, cheapie vivitar monopod, 3 batteries & random lens cloths & pens. And I schlepped that around Disney for a week.
The boss has me spending a week in Alaska this coming June, and I've been trying to figure out what goes and what doesn't. I know right off that the FA600 /f4 doesn't go.. It's case is too big to carry on (an airplane) and the lens
is too valuable to check through. (IMHO), yet wildlife photography is a big opportunity in Alaska. If I wasn't flying I would certainly take the FA600 but it's a bit far to drive and begone only a week or so.
That leaves me I think about 3 practical choices:
a) take my bag lens (FA 300 f/2.8) and a sack of Tele-extenders with the DA 1.4x likely being the extender of choice because it will easily maintain auto focus features. even in bad light because of its inherent speed.
but the DA 1.4x only gets you to 420mm effective, and the 2x_L only to effective 600 -- some chance of hand holding --- easy with a monopod.
b) Take the silver trunk with the Pentax-A -400 f 2.8 with a sack of Tele-extenders. the 1.4x gives you 560 and 2x-L which works well makes for 800 --- and stacked works too down side---It's heavy, and monopod
is the minimum--- but also older technology without auto focus. the glass though is fast enough and you can stop down a few stops to compensate for light loss inherent with extenders. But you miss opportunities
because the setup time is extended.
c) I've ordered a F 300 f/4.5 ----for the back up camera to take quick and dirty which can be pretty easily hand held while a more cumbersome system is assembled. (Translation--- My wife has a K-3 also)
d) forget the primes and go with a 150-450 zoom which LBA almost compels me to buy anyway.
