Nope. Can't lift it. The DOii is about the limit. Even the FE100-400GM gets heavy quickly now.
Won't be long and I'll be alone with the RX10iv....that's not so bad really, I'm still above ground and still trying.
You sound like me MM. I'm really having a difficult time with heavy camera stuff. I too am above ground and trying. My old Canon EF 400mm f/5.6L USM is once again getting a lot of use. I kind of quit using it much when the Canon 100-400mm f/4.5-5.6L IS II came out, but that too gets tiring in a hurry. Now the old 400mm is seeing a lot more days in the field. The Canon 400 mm DO is the heaviest I'll take out anymore, and my Canon 500 f4 L II will soon be up for sale.
