[Expired]New Arrivals: Tamron 28-300mm f/4-7.1 Di III VC VXD Lens (Sony E)

: Not as good as a7r3+28200 不如a7r3+28200

: Let me mention just one thing: the autofocus performance is subpar. Yes, it's a third-party lens, and you might say that doesn't matter. But isn't quick recognition autofocus the reason people buy Sony? Last weekend I took a newly purchased Sigma telephoto to shoot planes and it just couldn't lock focus properly. You might counter that Sigma's 85mm performs well - true! Because it's shooting people at close range where focusing difficulty is lower. 我只说一个，自动对焦不行，对，第三方，你或许说无所谓，买索尼不就冲快速识别自动对焦吗？我上周末带了个新买的适马长焦拍飞机，就是抓不住，然后你说，适马的85不是挺好的嘛，是！因为拍的是人，近景，对焦难度低

: Purchased the 50-400 买了50-400

: Can it only be used on Sony bodies? 只能用索尼机身吗

: Previously, I was strongly against travel zoom lenses. But after seeing the sample photos from Da Ma Mao Ben, I felt it was really good. It offers convenience, sharpness, and even comes with image stabilization and half macro capabilities. It's definitely not a loss to take it for travel. If this kind of convenience makes people more willing to bring their camera out to shoot, isn't that a huge advantage? If you prefer bokeh shots, that's another matter. You really don't need to worry about small apertures; just crank up the ISO. These days, Topaz and similar tools are amazing; dealing with mainstream ISO 6400 is no problem at all. 以前本来是坚决的反对旅游头的。但是看了大马猫本的样张感觉真香。要便捷有便捷，要锐度有锐度，还送了防抖和半个微距，旅游带出去并不亏了。如果这种方便能让人更愿意带相机出来拍何尝不是巨大优势。如果喜欢糖水另说，真不用担心小光圈，使劲开感光吧，这年头topaz什么的太香了，对付主流的iso6400都毫无压力。

: The aperture is a bit small, starting at F/4 and only F/7.1 at the telephoto end. In comparison, the 28-200 is more appealing and cheaper. 光圈小了点，F/4起步，长焦端才只有7.1。相比之下还是28-200更香一点，还便宜。

: It's good for travel mounted on an a7cii. 挂在a7cii上旅游不错

: But the Tamron 28-200 is F2.8-F5.6, and you can buy it for 550. However, it's RXD, not VXD. 可是tamron 28-200 是 F2.8-F5.6 ，且550就能买到。不过不是VXD，是RXD
