So I'm stuck between a rock and a hard place. I love my Z but need funds for a new lens to be able to pull in two new photography jobs. I'm thinking that if I sell the Z for the lens to get the work, the work will enable me to by something brand new next season. This is frustrating. Anyone here into photography that might be interested in trading a Canon 300mm f/2.8L or a 200mm f/2L?
