The conclusion is that this lens is incredibly good value against the Sony GM lens. The only lens that can compete in terms of value-quality balance is the Tamron 28-75mm f/2.8 which is a lighter lens but not as wide as the Sigma.
Krolop&Gerst jus posted the worlds first ENGLISH review of the new Tamron 70-180mm f/2.8 FE lens. It really looks like this lens can compete with the Sony 70-200mm GM for half the price!
Marc Alhadeff from SonyAlpha.Blog tested the new Tokina 85mm f/1.8 FE lens. he had previously tested the Viltrox 85mm f/1.8 FE and can confirm it appears to be exactly the same lens:
As a copy of the Viltrox 85mm F1.8 PFU RMBH STM , it gives basically same results but at a much higher price
So unless you prefer the different look of the Tokina I would suggets you save some bucks and get the Viltrox instead:
Well let’s get straight to th best news: The Sony A7III was the worse performing camera of the bunch because of “the amount of noise is unbelievable, it’s last in all categories and might not even be fixable in post”
The German youtuber Krolop&Gerst posted the worlds first review of the new Tamron 70-180mm f/2.8 FE lens. The most important news first: Tamron told them the price will be “around 1.200 Euros” which is less than half the price of the Sony 70-200mm GM. Moreover the Tamron weights 815g only compared to the 1480g from the Sony.
The reviewers say that the Sony lens has those advantages: – The Sony lens feels more solid
– The Sony has a tripod mount
– The Sony has internal focusing
– The Sony has in lens stabilization
– The Sony has more buttons
– The Sony has more reach 200mm vs 180mm
– Better flair resistance
The Tamron advantages:
– The Tamron is sharped in the corners
– The Tamron seems to have a better light transmission (1/3 stop faster in terms of real world t-stop)
– It focuses close 85cm vs 96cm
– The Tamron is a lot cheaperSAR
– The Tamron is lighter
– The new autofocus system works very fast in both stills and video mode
The reviewers conclusion is that the Tamron offers the same (if not a tiny bit better) optical performance than the Sony. Ad unless you need those Sony extras like extra 20mm reach, buttons and so forth the Tamron is definitely the best choice.
