I'll be interested to see how you like the G2. I have a love/hate relationship with my Tam 150-600 G1. The last time I used it it froze up three times in one shoot. I also got some great low light shots of owls thanks to the image stabilization. It just isn't as sharp at 600 mm as I would like, but it produces some very sharp results round 500mm and shorter.
Anyway, good luck with the new lens, and with the sale of the old one.![]()
