Chris and Jordan tested the new Tamron 35mm f/2.8 FE lens and they really like the lens optical performance (less so the AF performance).
Also Marc Alhadeff likes the new lens:
The Tamron 35mm F2.8 Di III OSD M 1:2 (450 euros) is an excellent lens for its price
It is part a set of new Prime lenses with all a short focusing distance , a 1:2 magnification ratio, a F2.8 aperture, same length, same weight
In term of sharpness it competes with the best : Sony FE 35mm F1.8 (700 euros) & the Sigma 35mm F1.2 DG DN Art (1500 euros)
Its sharpness is mostly excellent/outstanding on the Sony A7RIV and the results in term of color rendition / background blur are very good
