So far my longest lens for landscape was the Zeiss Sonnar 55mm F1.8 in my bag. Recently I often found myself in situations where I wanted just an intimate crop in the frame and 55mm proved to be not long enough on the Sony A7II. For full frame E-mount there is no budget tele-zoom option. Either you buy one of the FE 70-200mm versions or the FE 70-300mm. I consider the 100-400mm GM too heavy for myself. All these lenses cost a fortune and I don't want to spend that much. Fortunately adapting Canon lenses to Sony bodies is relatively easy and there are lot of different auto focus adapters available. I picked the Canon version of the highly regarded Tamron SP 70-300mm F4-5.6 VC USD lens used from eBay and a Viltrox EF-NEX IV auto focus adapter.
