Very curious about the performance of this lens. Price is super competitive as well if the optics are strong.

I really enjoyed the CY 100-300 and Canon L 70-300 but they are both large and/or have their drawbacks. I didn't love the FE 70-200/4 or the 70-300. For me, this is quite a useful FL for nature and landscape, and at under 600g, I would actually carry this for long hikes.

MTF chart at DPReview shows poor performance in corners of 70mm wide open, but quite good performance at 300mm wide open.

True, but it's wide open. Are these MFDs theoretical or actual though?

Looks like it will have noticeable astigmatism.

At 300g (!!) less than the Sony, I'm looking forward to some tests in the f8-f11 range. That price is insane too, maybe I shouldn't get my hopes up too high...

What's funny is that it's the same price as a Sony 1.4 TC which I used to use on their 70-200 GM (before I bought a 70-180 2.8) to get more reach...a stop slower obviously but I didn't need fast glass in those times anyways.

I agree a really good price if the performance holds up.

The weight, packed-size, and price certainly make it a strong value, assuming the optics are good, and, at this point, I think Tamron's earned the assumption the optics will be good.

Still, that 300g (and twice the money) get you some niceties with the Sony, like OSS, focus limiter and MF/AF switches, a focus hold button, and a constant .9m MFD, which gets you close to 1:3 at the tele end. I think the choice between the two would be heavily usage-dependent.

It even weighs less than the Sony 70-350mm crop lens

hmm, I guess we are a bit used to price of new mirrorless lenses.
Tamron 70-200 2.8 VC g2 DSLR lens is 1200, and optically superb. yet people say the tamron 70-180 2.8 with no VC is a bargain.
Tamron use to make excellent 70-300 vc dslr lenses in canon and nikon mount which were selling for 400 bucks.
The MTF shows severe astigmatism. the contrast is ok but the resolution is not that great as you get close to borders, esp on the wide end. lens has no IS, which is pretty significant on a high MP body at 300 mm. I just dont see how this is a huge bargain like some say.

I'd be curious how this lens would compare to their 28-200 lens. The super zoom is even smaller and from what I've seen quite decent at 200mm. You lose 200-300mm, which if it really matters maybe it's better to go for a 100-400mm lens anyways. I'd much rather hike with the 28-200mm and an ultrawide lens.

We have 70-180/2.8 and 28-200 and extra 100mm doesn’t cut it for me. I wish Tamron or Sony make a 300/4 prime.

I don't understand why Tamron is going the no image stabilization route. Now in all honesty I do have the 70-180 f2.8 and love it. And I set my minimum shutter speed to 1/250 sec. So I don't have any issues there. But 300mm is pushing it?? That decision by Tamron led me to not wait for a wildlife lens they may come out with and I bought the Sony 100-400.

The lack of IS makes it lighter and cheaper, it makes sense given more expensive heavier 70-300mm lenses exist.

I'll probably end up getting one of these as I'm currently using the Sigma 100-400C, but there are many times I leave it at home to save weight if I don't think I'll need it. This lens is the size/weight range that I would always bring it, meaning shots that I simply wouldn't take otherwise. That's worth more than OIS to me.

Is it too much to expect it to do 95% of what a Sony 100-400 does?

If so, for me the weight and size are even bigger selling points than price.

Yes, way too much to expect. The Sony 100-400 GM is a World class performer in speed and IQ, much more reach, superb build, in lens stabilization with multiple modes, and has two TCs that it can work with.

Tamron will be nice but no where near the 100-400GM level.

Can't I just have my cake and eat it too? Is that so difficult in lens design

If I didn't have the 70-350G I'd be all over this one. I'd go for it just because of the Tam 17-28 and 28-200. I've also got an EOS 70-300L that does triple duty on the Riv, the X-T4 and someday the R5 if it ever gets here.
Sadly I will have to pass but my gut says it will way way outpunch its price point.
