Tamron 28-75mm f2.8 Sony E

There’s nothing like renting a big telephoto zoom lens for shooting wildlife, sports, airshows or anything else far away, and for E mount, there’s nothing like renting the Sony 200-600mm G OSS lens!  If you can’t get the shot you need with this beast, you can of course shoot APS-C mode which would make it more like a 300-900mm, and if that doesn’t work, you might just need to rent a telescope instead!
