What telephoto lens is actually gonna get the best results for wildlife on the a6700 without being a total nightmare to carry around? Ive been shooting for years on my old a6000 but I finally bit the bullet and upgraded to the a6700 and wow the autofocus is just on another level compared to what I'm used to. Problem is my old 55-210 kit lens is really showing its age now and the quality just isnt there for the sharp detail I want.

Im planning a big trip to Yellowstone in about three weeks so Im kinda on a deadline to figure this out. My budget is sticking around the $1300 mark though I could go a bit higher if the glass is really that much better. My main thoughts right now are:

• Sony 70-350mm G
• Tamron 150-500mm
• Maybe a used Sony 200-600 G

I keep looking at the Sony 70-350 because its so light and the 1.5x crop makes it a 525mm equivalent but I wonder if I'll regret not having that 500mm or 600mm native reach for those far away grizzly shots. I'm just worried about the weight since the a6700 body is so small and I dont want it to feel super front-heavy while hiking all day. Does anyone have experience with how these balance on the newer bodies or is the internal zoom on the big 200-600 really worth the extra bulk? I just want something sharp that won't make my arms fall off by noon...
