Longteng 17 50 anti-shake This lens is extremely poor in workmanship, and it feels worse than the dog head of 18-55. Moreover, the anti-shake technology is immature, and the rear lens will shake violently and make violent noise. This lens is not suitable.
To get good picture quality, I suggest you consider 50 1.4G or Sigma 50 1.4. The viewing angle is just right on your half-frame machine.
Maybe when shooting scenery, you will feel that the wide angle after 24 conversion is insufficient, which is very easy to solve. PS has the function of taking pictures, and it is possible to take big scenes with high quality. Of course, you should have a better tripod
