UDレンズ2枚の採用で色収差を大幅に低減 The Canon EF 135 f/2L USM’s f/2 aperture allows a full stop more light being let into the camera than an f/2.8 aperture allows. This would translate to me either using an ISO of 6400 with a f/2.8 lens or using an ISO of only 3200 with an f/2.0 lens! The Canon EF 135mm f/2L USM ’s f/2 aperture also means the background is more blurred out The EF 20mm f/2.8 lens weighs in at a mere 14.29oz (or .89lbs) which means it is very light weight when mounted on your camera. This is significant when you compare it to a lens like the 16-35mm f Canon EF 24-70mm f/2.8L II USM Lens. Ultimate Image Quality, Excellent Build Quality, Wide f/2.8 Aperture, Very Fast Autofocus Speed with Precision Accuracy, Weather Sealing. If I could have only one lens, the Canon EF 24-70mm f/2.8L II USM Lens would be my choice. The 24-70L II is all about performance and reliability. Summary: This Canon L 17-35mm f2.8 lens has been highly reliable and takes pictures with an excellent look. Though the newer versions apparently test sharper, this lens produces excellent wide angle photos on my Canon R and focuses very accurately. Used they are an excellent value. The Canon EF 28mm f/2.8 IS USM Lens has a clean, smooth, fixed-size design that is comfortable to carry and use. While light and small, the 28 IS feels solidly built. The barrel is made of an engineering plastic that has a nice quality feel to it. Plastic is light - light is an often-desired lens characteristic.
