This may have been discussed here before, but I am an infrequent visitor. I primarily do hobby landscape photography in locations which require hiking and carrying photo gear in a backpack. Weight is a real issue. I currently have the A77 and A99 bodies with the CZ 16-80, CZ 24-70, and Sony 70-300 G lenses. Also a RRS tripod and head.
My question is how much am I sacrificing by going with the A77, 16-80, and 70-300 over going with the A99, 24-70 and 70-300 lenses for landscape work? I currently lug them all, and I am not getting any younger although in good shape. I am concerned about IQ and I sometimes make quite large prints.
Any informed comments would be appreciated!
