“Baiwei” can be said to be a very important lens in Canon’s EF bayonet, especially for some photography and product shooting, which is an indispensable mirror. How can this specification of lens be missing in Canon’s main RF bayonet? Not long ago, we reported that Canon has registered a series of new lens patents, including a RF 100 mm f / 2.8L is macro lens. Today, foreign websites have exposed the appearance of this lens.
From the exposure pictures, the overall appearance of this lens conforms to the current RF bayonet design. After all, it is simple and straight. The lens still has the conventional manual focusing ring and aperture control ring. However, the interesting thing is that this RF 100 mm f / 2.8 LIS macro lens has a “Sa” mark on the lens barrel We don’t know what the function is for at present. It may be related to a recent patent, but we guess that it may provide better focusing performance at different focusing distances? What functions do you think this “sacontrol” will have?
