Is Quan Huafu the Three Musketeers of Sima?

No, Sigma 17-50mm f/2.8 EX DC OS HSM is a lens specially designed for APS-C format cameras. There will be obvious dark corners on the full-frame camera, which can't be used normally.

The so-called Three Musketeers (the three treasures of the poor) refer to three kinds of Canon zoom lenses used by Canon SLR cameras (including film cameras and digital cameras), including: EF 16-35mm f/2.8L II USM, EF 24-70mm f/2.8L II USM and EF70-200mm f/2.8L IIUSM (Love Rabbit).

Canon EF 16-35mm F2.8L II USM lens is the third generation mirror king of Canon EF, and it is also a comprehensive upgraded version of EF 16-35mm f/2.8L USM lens. The lens adopts two UD ultra-low dispersion lenses and three aspheric lenses, and the optimized lens coating and lens position can effectively suppress ghost and glare.

5r comes standard with SEL 16-50. In addition to all Sony lenses, there are Sigma Three Musketeers, Longteng 18-200, Fu Lunda manual large aperture (without adapter ring), Zhong Yi optical manual large aperture made in China, and Tuli 500mm folding lens, all of which are E-snap lenses.

Sony large zoom E 18-200 is not recommended for the second generation. E 18-200 is a Sony lens produced by Longteng. It is the lens with the worst optical quality among all Tianya mirrors, and there is no one.

Sony ultra-wide E 10- 18 is optional. Sony has few choices of semi-non-anti-ultra wide-angle lens, among which the better wide-angle lens is Old Frog 9mm/f2.8, but the disadvantage is that it is manual and can't be played by novices. The other is 16mmf/ 1.4 (one of the three musketeers), which is of good quality, but the equivalent viewing angle is only 24mm, which is not wide enough. Zoom wide angle is only applicable to E 10- 18 and T 1 1-20.
