I wonder if it is copy variation, giving different corner results from Jannik's and Marc Alhadeff (sonyalphablog) reports?
Apart from 28mm, where they are good, Jannik finds only fair corner performance, Marc find them very good.

I think that it is a little flat to rate only center and border. If border means 90% image height, my rating would be very different too. This lens struggles in the last few (10%) pixels and that is what I showed here. Reminds me a bit of a few legacy wide angle primes in this behavior.
Another difference between our reviews is that he took pictures of a book shelf at close distance and I used a real landscape at infinity for my findings.
If you look at his border crops, you can see that his corners are also no marvels. I think we have a different definition of excellent corner sharpness. If you read carefully, he even agrees with the somewhat poor 35&50mm corner performance.
I checked my lens for centering of course and it looks good there.

I'm also not feeling that the build quality is so bad. My lens doesn't have that kind of a visible seam / joint that was shown in Jannik's review though. I understand such seam in a very visible location would feel annoying and could make the build quality feel worse.
I haven't noticed anything that would annoy me about the build quality personally. I was expecting it to be plastic and light and I've been pretty happy with the look & feel of the materials. It also mounts to camera very solidly. Also the zoom mechanism has a solid feeling.

Its a light weight lens, not a tank, its going to have lightweight materials. It doesn't feel cheap to me.
I think we have a different perception of quality then. I agree that lens build quality is acceptable for what it is, the same applies to the kit lens (and the FE 1.8/85 although that has a metal body). On the other hand, I don't like sharp burr on the hood, the visible joint on the top of the lens or the plasticky feel of the zoom operation. This are details that are better on the FE 3.5-5.6/28-70 and much better on more expensive options. Since everybody is comparing it to the GM now, this has to be mentioned in my opinion.

The lens doesn't feel as solid as the GM, but frankly I think a lot of that is due to the weight and smooth vs textured plastic. I am not a fan of the lack of damping on the focus ring, but the zoom action feels fine to me, if a bit simple. No worse than those on any high end 70-200, which also always felt like nothing special.
Considering the price, it feels very nice, but build quality is really hard to tell from the outside anyway. I find no creaks, no wobble at all in the lens tube, and smooth mechanics.... perfectly good for this type of lens. The hood does feel a bit cheap, and I don't like the sharpness of the front of the hood, bit overall it's nice. I do not have any seams visible in the plastic... Just smooth throughout.
I love the size and weight....it's far more compact in real world use than it looks in pictures, and it's night and day in comparison to the GM, though I think the GM is a bit better optically.

After reading Phillip Reeves Review I took a closer look on my Tamron lens:
I must look very close to dectect the manufacturing joint on my lens. I can't feel the joint with my fingers, for me his complaint in the review is not of interest.
About the sharp front edge of the lens hood: I took some sandpaper, in two minutes the edge was nice rounded. He also writes "The lens hood is made of cheapest plastic". Does he really know the chemical plastic mixture?
What is important is that Tamron believe the lens have a good build quality, they offer 10 years Warranty on the lens here in Switzerland!

I just read on a Chinese discussion board that the batch that have the focus issue were made in Thailand which have been distributed to North America market. Not sure whether this is true, I will cancel my BH pre-order.

Mine is made in China too (bought in Japan).
I took another close look to see if there are any seams and there's actually a very faint line that can be seen when observing very close in strong light around the same location as in Jannik's review but it's hardly visible and can't be felt with touch. I had not even noticed it before this evening when taking a very careful look.

I think people get me wrong here. I think the lens feels a bit cheap and has some issues that dampen the quality perception, at least from quality aware customers. It just feels not as nicely crafted compared to other native or legacy lenses.
That doesn't mean that the lens is manufactured badly, I can not make a comment on that without a teardown.

I think the joint is common for Tamron, have had a few in the past that most certainly had the joint, first time reading someone bringing up that point.
My toilets have that same joint too
after a while, it just disappears. It's probably an inexpensive process spent for welding, and hence cutting cost measure.
as for the SP designation, dont really care too much about that. MTF's show that this lens is slightly better than the 24-70 SP version, and I think that matters more.
10 year warranty is really sweet for you guys, I've done a 5 year warranty claim on my older tamron, and they honored it!!!
EDIT: btw, the stiff zoom loosens over time, and it's a preventative measure for creeping. Generally works well after a few months of usage.

I'm with you, it was actually one of the first things I noticed, and there's little excuse for it with modern manufacturing. i think I liked it to 1/2 step down from the 50/1.8, whatever the hell that really means. Personally I would have preferred an SP designation, the metal barrel and $100-$200 more on the price tag wouldn't have bothered me, but optically it doesn't disappoint for my use.

I just updated the review and put my statement a little into perspective - "The build quality is comparable to the Sony 3.5-5.6/28-70 OSS, maybe even a tad below that. That means that the lens is well assembled and without play in the focus/zoom rings but without the fancy and sturdy impression of the other available FE-lenses. The lens barrel is made of plastic and the focus and zoom rings are rubberized. The lens mount is made of metal and has a rubber gasket".
My criticism about the burr and the joint remains. Other manufacturers do that much better, why shouldn't I mention that?

Jannik as someone that tests lenses and cameras always say what you see as good , bad or in different. Regardless of the heat. You’ve earned my respect and appreciation for your testing. Your out there trying to give good data and that’s more important than anything else.

I’m still in debate on this one. So want to hear real data without the fluff. I need more like 24 but I could always cheat doing PR and use my Loxia 25 as well. We really need a 600 dollar 24/25 and 2.8 would be fine.

You can puck up a nice used Batis 25 for around $800. Exceptional lens for that price.
