                    Kyle Kokotajlo Sigma 150-600mm eh? I am renting one at the end of October and hoping to purchase around Christmas time.
 
                    Shenandoah Yep, really nice lens! I took it out for a test drive this afternoon. Hoping to go do some bird watching on Saturday with it.
 
                    Jennifer Faye Nice!!!
 
                    Suzanne Congratulations on your new lens. I got a 70-400 mm Sony lens a few months ago and my left arm has become increasing stronger.
Maciek Korsan what's the focal length? :O
