Anyone have some feedback on how either shoots with overcast, typical Seattle skies? I'm planning on a trip up there and feel I need more reach then my Nikon 70-300 provides. Particularly with Orcas and Bald Eagles or other wildlife. Most likely I'll have at least a Monopod but maybe some shots will be hand held. I've tested at Tamron 150-600 and with the IS I can shoot it, maybe not all day, but it is possible to shoot on the fly. That was on a bright, clear day though.
The prices for either are pretty close, I'm selling one of my D7000s and the 18-140 to partially fund it. I realized I hardly shoot midrange and get by with a 10-24/35/70-300. The Sigma would give extra coverage if something moves in close though. The Sigma I can snag for less then $1000 used and the Tamron has a small rebate that'll make it about $1000. If it makes a difference I rarely post process, even then I don't do anything more then a 10sec fast edit. I also don't print anything big, a few 8x10s here and there. I also don't pixel peep.
Thanks in advance!
