Marc Alhadeff from SonyAlphaBlog just posted the first full review of the new Tamron 70-180mm f/2.8 FE lens. He writes:

The Tamron 70-180mm F2.8 Di III VXD (1499 euros) is an excellent lens proposed at a very reasonable price. It completes perfectly the 2 other Tamron zooms but the quality of this zoom is clearly higher than previous Tamron Zooms. Indeed it supports perfectly the 61Mpix of the A7RIV whereas the 2 other zooms where showing their limits on the A7RIV

To achieve this performance at this price and this reduced size and weight Tamron had to make some choices:
180mm instead of 200mm
No optical stabilization
Lens extends when zooming
No “fancy” buttons on the barrel
No tripod foot (but you don’t need it considering the weight)
Not compatible with Sony TC

All the above compromises do not influence at all the image quality that is excellent (sharpness and bokeh) and allow for a weight and price divided by 2 compared to the Sony GM

Pros
Excellent sharpness on the entire field and entire range at all apertures
Very small and light
Very reasonable price
Very good bokeh and soft background blur
Extremely fast , silent and accurate AF
Very low level of chromatic aberrations
Moderate vignetting
Very good resistance to flare
Fully weather sealed

Average
Color rendition little bit yellowish
Not compatible with Sony TC1.4 & TC2.0
No button to switch to MF, to set a custom function, to limit focusing range
No optical stabilization

Cons
Huge distortion between 135mm and 180mm (no lens profile yet available as of April 2020)
Lens does extend when zooming and the zoom ring is quite dampened , so no smooth zooming possible in video
Does not look “Pro” if your are pro wedding photographer

The Tamron delivers similar performances to the Sony FE70-200 F2.8 GM in most cases and even surpass it sometimes (corner sharpness and sharpness at 180mm, portability) at half of its price. A superb Performance !

We expected the new Tamron lens to be optically very good performer. But the big question was f the new autofocus system can match the superb performance of the Sony GM zoom. Well it seem it does! Check out the review:

UPDATE: Here is also a new video from Marc Alhadeff:

The new 70-180mm FE Tamron lens implements a new generation motor that promises improved AF speed performance over the previous Tamron zooms. Here are a couple of short autofocus tests from Germany and Japan:

Looks very good so far!!!

Our SonyA7III Facebook member Kenneth posted a set of image samples (you can only see them if you join the group sorry). He writes:

I find the AF very good on both stills and video. Stills AF are expandable point and video AF is wide. I feel this will be another killer lens from Tamron! Cant wait to add it to my arsenal while traveling the world shooting rockstars. I will do a deeper video review when I get my copy of a finished product (this is not).

CameraLabs published the Sony 20mm f/1.8 FE review:

“The Sony FE 20mm f1.8 G is an ultra-wide prime lens designed for Alpha mirrorless cameras and corrected for full-frame sensors. It delivers an ultra wide field-of-view that captures comfortably more than a 24mm, making it ideal for expansive landscapes, tight interiors, wide astro photography, as well as vlogging or environmental portraiture. It has a decent feature set including a de-clickable aperture ring and multi-purpose focus hold button plus its optical performance even surpasses the very good Sony FE 24mm f1.4 GM. This deserves a Highly Recommended!“

Thanks SansM. :)

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.
