This is the kit I will be taking to Alaska in May. It will give me a range of 14mm to 1050mm. Originally my plan was to take only 4 lenses -- z14-30, z24-120, 300 PF, 200-500. All these lenses will work with the z7 with the adaptor. The problem I foresaw was that if the z7 went down, I would only have a focal length of 300-1050 to work with, which would not do for town and landscape shots. I added the 24-85 so at least this would give me a range of 36-127.5. I know this kit looks heavy but it weighs slightly less than 23 lbs. Some of you may question why I would include the 300PF lens when that range is covered by the 200-500. The 300 may be the sharpest lens in my bag and on the D500 will give me a range of 450-630 (with the 1.4). That means on some excursions I may leave the 200-500 in my room which will lighten the backpack by 5 lbs. I will also bring a waist-pack that will hold a flash and one lens. When walking around town, I will take only the z7 with the 24-120, and carry in the waist-pack the 14-30, a couple of extra batteries, polarizer filters, and a flash.
