As good as everyone elses 70-200 f/2.8s
Crutchfield Customer Review (What's this?)
I've owned several 70-200 type lenses over the years from multiple manufacturers (Tokina, Tamron, Canon's f/4 and f/2.8 versions) and this one is easily as good as the best on the market (Canon's 70-200mm f/2.8L IS II, Albeit that has since been superseded by a Mark III version I have not shot), its big and heavy yes, but for those of us who need the extra stop of speed over the f/4 the price is worth it (And to be honest it doesn't bug me too much, I actually consider this my "lightweight general purpose" telephoto zoom compared to my Sigma 150-600). The autofocusing is extremely fast and accurate, able to keep pace with my very quick Cardigan Welsh Corgis zipping around in the snow on my A7III. Its also one of the lenses that really lets the A7IIIs full capabilities shine. The OSS works a treat, I've shot down to 1/15 at 200 with no issue Sharpness and contrast are excellent all over the range as far as I can tell, granted im shooting the less demanding A7III's 24mp sensor and not the R's 45mp one, but regardless I doubt you'd be disappointed. The only real downsides are the price and the weight, This definitely has me considering the vertical grip for my A7III for when im going to be out shooting with it for an extended period of time and compared to its rivals from Canon or Nikon its a bit pricier, but its worth it for those of us who need that extra stop of speed. If you're considering it. Go for it. You wont regret it.
Pros: Sharp, Extremely fast focusing on my A7III, Excellent contrast, Beautiful bokeh, Excellent close focus and maximum magnification capability
Cons: Price, Size and weight
