had a mirrorless and a basic nikon before but have a canon 6d now just the body though

a lot of mufukkas shoot portraits with the 70-200mm. it dont really matter. it's more dependant on the style or your style. if you go to a photography forum, they gonna say on full frame, 85mm prime for upper body, and 135mm prime for headshots. both focal ranges are covered with the 70-200. if you doing street shyt, any thing goes. you probably dont want that ig ass fukk 70-200mm with you cuz that bytch is huge.
