Different pros: For such money - only manual focusing. And here, even without a motor - but quite a good autofocus. I use it on a FF camera, Tamron 24-70 G2 is also available. So, on the tamron, of course, the class is visible (sharpness, colors, XA, vignette - everything is better) - but this cheap fix is at least comparable to a large and expensive (70 tr) reporter. If your camera supports a screwdriver and you want a fix - take it easy. I've had it since 2022 and it's still in service. Some cons: don't expect miracles from him. Autofocus is blunt, there is enough distortion, sharpness is 4. On the other hand, if you compare with some whale glass, this one will give a better picture.
