Cool shots!
I´m also hoping that the bear market doesn´t last for too long. And for the same reason as you. I also want to buy a new telephoto lens. But I´m not completely sure yet which one. I also saw very good photos from Sigma 60=600. So maybe I´ll go for that one ...
Sigma lenses are nice. They have a 150-600 that I have been looking at too.
