The guy is impressed. Focus speed, noise and accuracy on par with Sony 1-4GM and 2-6G, the best focus performance he's seen in a 3rd party lens. Very sharp, no difference to the Sony's. The weight difference is not that big to notice, but size when packed/transported is much better than 2-6G. Bokeh is on par with 2-6G but not as nice as 1-4GM. The one negative he sees is that the stabilisation is not as good as with Sonys, while close focus stabi is ok, it leaves lacking with focusing at the horizon/infinity. But he says thats very subjetive and can always be improved with firmware updates.
One thing he noticed (that I didn't pick up earlier) is you can lock the lens at any focal lenght by pushing the focus ring away, not only at 150mm with the lock switch.
Cheers, A.

This reviewer appears to be comparing it to the Sony 200-600; can anyone who speaks German give a summary?

That's what he said I don't own any of these lenses so can't judge. But I do like what I'm seeing here so there is a good chance I'll be buying this tammy...

Looks like the German bloggers have generally gotten the first go at this lens, another review in German:
That's because we Germans like to peep into our neighbors houses, either to watch them doing naughty things or to police them (e.g. whether they meet more people than they are allowed by the Covid regime). So we are target group no.1 for tele lenses.

Found this helpful Chinese review too, but there have not been any English reviews so far as far as I can tell. I'm getting 28-75 vibes though; good IQ and sharpness but slightly nervous bokeh and AF quirkiness. I think that it's still a bit of a hard sell vs the Sony 200-600, especially at the price point here in Europe.
I am quite eager to learn more about this lens. I had settled on the 200-600. The price difference - while significant - is less of a deciding factor to me than performance vs size. If the Tamron can do everything the Sony can do but with 100 less reach in a considerably smaller package (I am constantly on planes), this could be enough. I am also curious to see more info on its 1:3 macro capabilities (sharpness and focusing at close differences) - as this is one of the reasons I was considering selling my Sigma 100-400 for the Sony 100-400.

The Sony 200-600mm has a greatest magnification of only 0.2 x or 1:5 but it takes TCs, and the Tamron 150-500mm doesn’t take TCs but is smaller and has better macro range. This makes the choice a bit difficult.
The range of the Tamron 150-500mm isn’t to far from the Sony 100-400m f/4.5-5.6 + 1.4x TC which equals 140-560mm with a speed of f/6.3 -8. The Tamron turns out a bit faster being f/5-6.7 in its 150-500mm range. Of course these aren’t a 100% apples to apples comparison but still probably as close as we get. If you add a 1.4x TC to the Sony 100-400mm the combined weight gets closer to the Tamron 150-500mm as well.

What is the greatest magnification of the Sony 100-400GM?
Anyone want to translate. Unfortunately my grandparents choose not to teach their children the mother language. Understandable at that time in history but bummer none the less

I'm curious about the focus breathing of Tamron. Sony 200-600 has bad breathing. At closest distance it's merely 525mm. At normal shooting distance it might be around 575. Not too far from 100-400 with TC (technically 560, but 100-400 also have breathing). I'm sure 200-600 is should be pretty close to 400mm prime with 1.4TC. Still 1/6th stop brighter than Tamron
Didn't find anything usefull in this one, but the one before gave some useful stuff:
- about apperture values 250-390mm f5.6 (as sony 1-4) and 400-490 f6.3 (as sony 2-6) leaving only 500mm with f6.7 - didn't find this information before
- The 2nd good thing was stunning sharpness across the frame from center to extreme corners wide open and that on an a7rIV. No problem resolving 61mpx whatsoever
- For macro shooters-> guy says he can't see any focus breathing
- Flare resistance superb, not a sign of it until the light source gets in the frame
- Focus speed and reliability great
- One odd thing he found were some strange bokeh balls where there were some small point light sources in the frame (they look a bit like amoebas) but not always and there was no way to reproduce them in the studio - and he tried hard. Other than this strange phenomena he finds the bokeh butter smooth.

Taking pictures of boats and flags aren't very helpful when comparing to the Sony 1-4 or 2-6. The Sigma 1-4 looks sharp on testing, but when you do wildlife, there was a significant difference on how the eyes look due to lack of microcontrast.
