- Excellent image quality. In comparative tests, this lens is not inferior to the Sony 70-200GM - and outperforms the 70-200G. Sharpness is enough with the head to allow a 24 MP cropped sensor, and there is nothing to say about a full-frame 24 MP. Vignetting and distortion within the norm.
- Small weight. Historically, fast aperture optics 70-200 mm weighed around 1.5 kg and had a length well over 200 mm. I had to choose: either we sacrifice aperture and take 70-200 f / 4, or we have a lens that requires a completely different level of involvement (i. E. huge and terribly heavy). Tamron 70-180 managed to combine the advantages of both. At the same time, the length came out even a few centimeters less than that of the 70-200 / 4G, and the light filter was 67 mm versus 72 mm.
- Very fast and generally silent autofocus. From that series when you simply don’t notice the work of autofocus. On the A7III it's perfect, on the A6500 it's worse, but also good.
- Great for portraits. The lens gives a very soft (for zoom) blur and for an amateur it will easily replace any portrait telephoto lens (85, 135, 200 mm). Of course, portrait fixes give the best quality, but they lose a lot in versatility.
- Appearance that does not attract attention. The lens looks like an amateur 70-300. Unlike long white “trunks”, shooting at 70-180 does not cause unnecessary interest among others compared to any other optics.
- Macro mode 0.5x (only at 70 mm and in manual focus mode). An interesting feature of the lens, which makes it possible to shoot various small objects. It requires your subject (which will be in focus) to be in the center of the frame, as the periphery will be heavily blurred. But as long as the depth of field in macro is only a few millimeters, this does not cause problems.
- Easy, smooth and short zoom stroke. Although the zoom has a retractable trunk, it is implemented well.
- Some kind of moisture protection.
- Firmware V2 solved the problem with poor performance of IBIS at 70mm: https://www. Youtube. Com/watch?v=ELIo_3x8_2w
