看起来是旧的光学设计 而且还不支持调焦底座
四大改进 对焦速度 防抖能力 外观设计 防水防油镀膜

※Model A030 is not compatible with either the Tamron TELE CONVERTER 1.4x (Model TC-X14) or Tamron TELE CONVERTER 2.0x (Model TC-X20), which are optional accessories.

It is also not compatible with the optional TAMRON TAP-in ConsoleTM that enables a lens’s firmware to be updated and features to be customized.

Product Highlights

Improvements in AF speed and responsiveness
Improvements in the control circuit and AF algorithm of the previous Model A005 have enhanced both focusing speed and accuracy, which enables a moment to be captured without letting the photo opportunity slip away, and which makes the A030 a suitable lens for photographing fast-moving subjects.
Improved VC functions
Improving Tamron’s unique VC (Vibration Compensation) functions has improved the responsiveness of the VC lens elements, and Model A030 achieves a higher image stabilization performance level of 4.0 stops according to the Camera & Imaging Products Association (CIPA) standard.
External design renovated
The zoom ring and focus ring using linear-based grid patterns and the brand ring in tungsten silver create an external design with a high-grade feel.
Equipped with Fluorine Coating to improve user-friendliness for the lens
The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.

然而旧的只要1500左右就有二手，新的卖3000谁要啊

从90微开始 就是满满的没诚意了

art出翻新的时候 30 1.4和85 1.4这种本来就画质可以的镜头 依然做了大改才发布的
腾龙真是为了换壳而换壳
听说还有换壳之后依然不能usb调焦的 坑爹啊

有人说外观变化，仔细看根本大同小异，只是外壳配色和对焦环的小改动

我也很失望，现在用的就是旧版70300VC，希望能出一只画质切菜有提升的70300，我就出掉旧的，结果看来只是更新对焦和防抖
