The Canon 50mm f/1.0 L is the world's fastest lens ever made for any 35mm SLR, DSLR or any autofocus camera. It weighs twice as much as the 50mm f/1.2 L , four times as much as the 50mm f/1.4 USM and over eight times as much as my favorite 50mm f/1.8 II . The two lenses that ever-so-slightly exceed it are the new RF 85mm f/1.2L USM lens for the EOS R mount and the EF-M 32mm f/1.4 USM lens for the EOS M mount cameras. The EF 35mmL II lens is a fairly expensive lens although it's in high demand by most professional photographers and has Canon's BR Optics (Blue Spectrum Refractive Optics) which The EF 35mm f/1.4L II USM from Canon is an L-series prime wide-angle lens featuring Blue Spectrum Refractive Optics and a maximum aperture of f/1.4, making it ideal for shooting in low-light situations and for controlling depth of field. Two aspherical elements and one Ultra Low Dispersion (UD) element combine with the BR element to control Another key difference - whereas Canon's lens still costs around $250 used; we understand that the new Yongnuo 35mm F2 is likely to cost around $115. Keep an eye on Yongnuo's official eBay and Amazon stores for more information. Yongnuo 35mm f/2 key specifications: Canon EF mount; AF/MF; Minimum aperture f/22; Minimum Focusing Distance 0.25m/0.8ft .
