Not long ago I managed to trim down the weight of my camera kit. The ever tightening stance of the airlines caused me concern. I even managed to get a lighter pair of binoculars. But …
Inevitably the weight has crept up again. I currently carry two cameras when I travel, one for landscape and time-lapse, a Lumix GH4, and a Cannon 7d mark ll with a telephoto for wildlife. At home I leave a full frame Sony with a nice macro lens. Of course none of them talk to each other, three different sensor sizes, incompatible lenses. Why? Because no one just buys a whole kit in one go and times change.
I’m thinking ahead to another big trip. Do I buy a bunch of lenses for just one of my much-loved cameras? What happens if it fails in the time I’m away? It is so hard but fortunately there is a flow chart …
It doesn’t solve the problem but it does amuse you while you ponder.
