HELP - Oly 50-200 or Sig 70 - 200
Hello happen to have the Sigma and the Oly Mk1
I prefer the Oly wide open for sharpness and detail. Focus speed is not a problem even for sports, but judge for yourself.
The Sigma 70-200 wide open ISO 1600
The Oly 50-200 wide open at ISO 1600 Apperture Priority, f3.2 at this focal lenght
At f3.5 the Sigma gets sharper
Altough at lower ISO the Sigma can do this wide open. ISO 400
The 50 f2.0 macro is still my favorite
Hope this helps.
Done my first 10,000
