    Canon EF 100mm f/2 USM lens...superb portrait lens for full frame cameras5.0/5

    Canon EF 100mm f/2 USM lens...superb portrait lens for full frame cameras The Canon EF 100mm f/2 USM lens is an outstanding value. The quality of images it produces on my EOS 1Ds are outstanding, even with prints up to 16x20. The focal length provides just enough compression for individual portraits and couples shots while allowing a comfortable working distance. Having previously owned the EF 85mm f/1.8 USM lens, I've come to the conclusion that the EF 100mm f/2 USM is my lens of choice and is a dependable workhorse of a lens that always delivers the money making image!

    A bargain for 100mm F2 at this cost5.0/5

    A bargain for 100mm F2 at this cost I looked at this lens for a long time and read many reviews. I am moving away from Canon kit tele lenses to Primes trying get the most out of both portrait type photography and sporting events including some indoor shots. The much lower F stop of F2 compared to the Kit lens's F4 or smaller is well worth the upgrade. The ability to shoot indoors in a Gym with medium lighting is nice. At 100 mm a tripod is not essential if you position correctly. It is not Macro, but I wanted the sharpness over that feature in the sister to this Cannon option. I chose 100 over 85 for the sporting events. I am glad about choosing this lens after considering both other choices. Low F stop, very sharp, low distortion and very little flare. At about 1/3rd the price of an L series. If cost is an issue this is a good value for a handy length and well made lens. With the Nifty 50mm 1.8STM and this 100mm F2 the Bokeh in my portrait work is taken to a new level of creativity. All at a budget level suitable for the amateur work I do.Read full review

    Great lens!5.0/5

    Great lens! Sharp in low light and silent AF. There's no way to control aperture except through the camera. So if using an adapter, make sure it has electronic connection!
