Canon EF 100mm f/2 USM Reviews

Wlcastleman compares the Canon EF 100mm f/2 USM to Canon EF 85mm f/1.8 and Canon EF 135 mm f/2 L and writes;
“This is an excellent lens with overall good lens sharpness, contrast, and fast autofocus function. It allows a little longer working distance than the EF 85 f/1.8 that may be ideal for some in portrait or performance photography.”
rating: N/A

SLRLensreview reviews the Canon EF 100mm f/2 USM and writes;
“The lens practically has no weaknesses – excellent image quality, low level of artifacts, fast and accurate AF system, pretty affordable price. Build quality, while not as good as with L quality lenses, is not too bad either.”
rating: N/A reviews the Canon EF 100mm f/2 USM and writes;
“The Canon EF 100mm f/2 USM is one of the “can’t loose” offers in the Canon lens lineup. It performed almost flawlessly in all tested categories. It’s interesting that the figures are marginally better compared to its more popular sister lens (EF 85mm f/1.8 USM). “
Rating: ★★★★★ reviews the Canon EF 100mm f/2 USM and writes;
“Wide open at 2.0 the lens performs magnificently, tack sharp in the eyes (with a soft tip of the nose, of course) up to 16×20. Edge to edge quality is better at 2.8, and at 4.0 the lens produces sharper Images than my 70-200/2.8L on the same settings.”

The-digital-picture reviews the Canon EF 100mm f/2 USM and writes;
“The Canon EF 100mm f/2.0 USM Lens is a very sharp lens. I found the 100 f/2 to be sharp at f/2 and only improves slightly when stopped down. Well, all lenses become less sharp somewhere around and beyond f/16 because of diffraction. Corner sharpness is good as well.”

User Opinions

Canon EF 100mm f/2 USM User Reviews

Excellent prime! | Rating: ★★★★★
“I love this lens. I’d previously tried a friend’s and was quite impressed with the sharpness from f2.2/2.5 onward, and the bokeh around f2.8/3.2. Upon purchasing the lens, I was overjoyed to discover both better sharpness (impressive wide open and just great by 2.2/2.5 in most circumstances) and smoother bokeh. “ – by G. Lordi

An awkward focal for a crop SLR | Rating: ★★★★☆
“Fairly sharp from f/2, good contrast, fast and silent AF, and only moderate color fringing. But the focal length is just *so* inconvenient… The bokeh, focal length, and extreme background blur made it my favorite lens.” – by David Indech

Excellent Lens | Rating: ★★★★★
“As an “intermediate” level photographer, I have to say that this is one of my favorite lenses. I get sharp photos every time I use it and can take shots in fairly low light. I carry this lens, as well as my 50mm 1.8, everywhere with me.” – by Courtney Mann

Canon EF 100mm f/2 USM Telephoto Lens | Rating: ★★★★☆
“We’re very happy with this lens. It produces sharp images at higher shutter speeds due to its wide aperture. You typically lose two or three stops with zoom lenses in the same price range. This is a good lens for medium telephoto applications.” – by Jonathan D. Williams

Great prime from Canon | Rating: ★★★★★
“AF is silent and fast. I use this for children indoor head shots. 50mm doesn’t give me enough room to work with and it makes my subject self-conscious… Only the hood is of secondary quality, feels cheap and the snap-on feels unreliable. My hood on the 50f1.4 is way better, and cheaper as well. “ – by Luving it

small, sharp, great portrait lens | Rating: ★★★★★
“I prefer this fast lens to the 85 1.8 – it simply produces a better portrait in my opinion. Lovely, small, light….the perfect little lens without going to an L. Highly recommend; I use as a back-up and always have it in my camera bag. Love it. “ – by M. ANNE

one of my favorites | Rating: ★★★★★
“I love this lens. I bought it basically because it is the longest focal length with a really large aperture under $500 ($925 for the 135 f2 and $4800 for the 200 f2). It focuses quick and is razor sharp, even wide open (I find I shoot with it 95% of the time at f2.0). On my crop sensor 40D it acts as a short telephoto and allows me to capture great action and tight portraits with perfectly blurred backgrounds.” – by Brett Maxwell

Canon EF 100 mm F2 | Rating: ★★★★☆
“I love this lens just wish I had gotten it sooner. I am still learning how to best use it for action shots, but right now it’s far better than any other lens I have for that purpose. It takes beautiful landscape and portrait photos.” – by K. Carey

AMAZING portrait lens | Rating: ★★★★★
“This is the most amazing lens and produces incredible portraits with a sharpness that is unmatched. It also creates a very shallow depth of field with a smooth bokeh.” – by Douglas Marshall

Features & Specifications

Canon EF 100mm f/2 USM Specifications

Another option in high-speed moderate telephotos, this compact lens is ideal for portraits and low-light work. Compared to the 85mm f/1.8 USM lens, it provides that little bit extra of telephoto power sometimes necessary outdoors or for candid shooting. Like the 85mm, it’s super-sharp (even wide-open), and has fast USM autofocus along with full-time manual focusing.

A medium telephoto lens with a large aperture brings the subject closer, creates excellent background blur, gives a longer flash range, and affords a faster shutter speed to freeze the action. A standard zoom lens, with its natural angle of view and perspective, captures the subject plainly, with no special effects. However, you can use standard lenses in creative ways by varying the subject distance, aperture, and angle.
