I know this is a ridiculous looking photo, but this is actually my own image, and a setup that I do use from time to time. A great amount of my nature photography is wildlife based, and wielding a super telephoto lens around through the woods and wetlands means having a dedicated tripod with a heavy duty head. That is fine and good, but I hate being limited while I’m exploring, and feel a bit naked not having an easily tripod mountable macro or all-in-one lens to fall back on too.
Pictured here are two of my Canon DSLRs, the top camera with my Tamron 90mm VC macro lens is bound to my Canon 500mm f/4 setup via a Gorillapod Focus (portable tripod). Granted there are plenty of opportunities for the whole combination to swing and sway, yet I am still able to get some macro shots from the top camera using low ISO speeds for maximum image quality.
Note that I don’t walk around with them bound together like this, as it isn’t entirely stable. Generally I sling the big tripod + big lens over my shoulder, while wearing the smaller camera with Gorillapod connected to it around my neck. I connect the 2 setups only when I am going to shoot with the top camera. It ain’t foolproof and it ain’t pretty, but sometimes it does what I need it to do.
If you have a better solution, please let me know!
