HOWEVER; AT 5.6, 8.0, 11, ITS TACK SHARP. Again, for the price I don't mind this, especially since I really don't think I'd ever want to shoot at 2.8 with this lense. I bought this for wide landscapes, or Architecture where I personally want alot of detail and sharpness. I haven't tested it with astrophotography. For the price, it's a great lense that CAN produce quality pictures, with slight limitations that again for the price, I can totally live with. I will update this with photos asap. 头几条评论都好长那。看起来也就是这么个价钱，估计国内很快也会掉到2000以内。
et me start by saying I'm a pretty big fan of Tamron, I own the Tamron 28-75 on my A7III. The price point of this lense is VERY good for the overall quality. That being said, Its not perfect... 1> Auto Focus is a tad slower, alot louder! To me I really don't mind how loud it is, as I won't be vlogging with this, however I do need to get used to the fact it does not grab onto the subject as fast as the 28-75. It's not wildly slow, it's just a bit slower, and if you're not used to that and you're running and gunning you might miss focus. Take a breath, give it a second, and take the shot. I'm just so used to trusting my 28-75 to catch focus lightening fast, I need to keep in mind this is slower. 2> at 2.8 I have not been able to produce a sharp image, and honestly it's hard for me to even tell where the focus is, it's so soft...

同r5 3600 20年第10周 1.2v 4.4g FPU 49分钟烤机稳定，没继续测试。就是有谜之卡顿现象。不用进游戏。在windows界面，偶尔鼠标就不动了，过个1，2秒就好了。这个问题不知道能不能解决呢？
