Which lens is better, Sigma or Longteng?

Longteng 24-70 is better. Tenga032sp24-70mmf/8diVCUSDG2 is a Canon bayonet version, and the clear "FORCANON" can be seen at the bottom left of the box.

Longteng and Sigma are two major lens brands in Japan. The previous lens is worse than Longteng in optical quality and process quality, especially in processing technology, cable life and quality control.

If Longteng and Shima choose one, I personally prefer the lens of Shima, of course, the art version, so I won't say the old version. Whether this lens is good or not, besides publicity and evaluation, the best measure is to use it yourself and try it in a physical store. Of course, the premise is that you have the ability to distinguish between good and bad.

The relatively heavy Sigma 354 has clear picture quality. The color of the photos taken by Sigma 35 is a little dry, and it will be out of focus in the SLR camera, and it will focus quickly when switching to the RF port. So Longteng 354 is good. The price difference is not too much. I will definitely buy a new one. Longteng 354 is better in Jiao Wai.

Compared with the previous work, the biggest feature of Longteng A032SP24-70mmf/8DiVCUSDG2 this time is that on the basis of the original excellent lens structure (17 film and 12 group), the focus is improved, the anti-shake and anti-glare ghost performance are strengthened, and the lens is sealed, which can be said to be a considerable progress.
