I'm getting g ready for a canoe trip with a 3 clients. I'll be packing my stuff. My Pelican cases have room for the 60-250 or 200, the 28-105 and an old FA-J 18-35 and a couple TCs. and a 50 macro. It's a tight squeeze but I make it fit. There is no room in my cases for bigger lenses, and no desire to carry more weight. I'm already carrying 70 pounds , often for more than a kilometre.on portages. I would buy more compact glass, I won't buy bigger. So in terms of lenses I can justify, bigger isn't better, in my world it simply doesn't exist. It's logistical. Up until the K-1 Pentax with their excellent small lenses were my guys. Now I'm seriously starting to wonder.
But, I can totally solve this problem by selling the K-1 and going back to APS-c so, no sweat off my back one way or the other. The K-1 is with me for now, but I still haven't decided I'm keeping it.
I'm not sure we are having an argument.
What I'm trying to discover is what advantages there are of the 70-200 over the Canon, Nikon Tamron and Sony versions. It's heavier, what does one get for the extra weight? It's a theoretical discussion, I won't carry a lens of that weight, but it's still of interest.
It's hard to think much about the new 50, it's not out. No one has it, what is there to say, except it might be too big for some of us, based on a 3D printer mock up. This is a thread with no real information, probably why it's 100 pages. Once you have a physical item present, there's little to debate.
