I prefer the rending of the DFA24-70, but it has a 82mm front filter thread, which means all of my ND and ND grad filter sets purchased for apsc don't fit, I'd need to buy again Pro 100mm filters to use on the newer DFA glass.
The exception is the DFA28-105, it has 62mm front filter, it's weather sealed, it's perfect for landscape I can use all of apsc filters. I can nearly have that DFA28-105 in a pocket, that + the K1 + box of ND grad fit in the same bag I used for the K3. Next time I go for waterfalls in spring time, it's going to be with the 28-105, the 24-70 will stay at home.
