Originally posted by northcoastgreg I envy anyone who doesn't find the DFA 15-30 too heavy. You are truly fortunate. It's a great lens, but it's four times heavier than my FA 20-35, and that's definitely too heavy for me.
It depends on your use case.
When I'm hiking 15 miles with my camera strapped to my chest ready for lots of photos as I walk, yes, it's too heavy and I'm likely using the more versatile 28-105 anyway. If I'm hiking that same distance for tripod-mounted ultrawide photos at specific scenic spots, then the 15-30 and camera are in my backpack most of the time and it's not too heavy.
Yes, I wish the lens was lighter, but that would mean sacrificing f2.8 (good for astro landscapes) or image quality. Many of us would like to see Pentax release a compact ultrawide FF, maybe an update to the discontinued 20mm, or something like a brand new 15-30 f5.6 if that's optically possible.
