I’d not say that from portraits ( or bokeh) perspective, but i’d ask that from amount of light needed perspective.
I’m (.. currently) in Chicago and it’s winter here for next 5-6 months. Meaning whatever event I’m going to get is going to be in indoor lighting conditions. (Which means inadequate lighting conditions.. I don’t know if it’s only Chicago .. but there is strange fascination with very warm colored lighting ... all party rooms got that. ).
Also (and this is what i heard ) lens do better stop down or 2 ? ( for my 24-70 2.8 i find sweet spot to be 4..). For f/4 if I’ve to go step down or 2, I don’t know how crazy my ISO need to be?
From that perspective, I’m thinking, I’m not going to buy lens again and again and if i do have 2.8 then given low light, i can use aperture as way out.
I know tamron 70-200 got focus breathing issue. But it is at (nearly) same price range as nikon 70-200 f/4.
Hence the question, won’t i need wider aperture as 2.8 ?
In that case? Focus breathing of tamron is as bad as to ignore $1400 saving I’d do by not going for nikon ?
I can delay purchase and rent for a while i save more to go for best possible option.
