Canon EF 28mm f/1.8 USM Lens Review @ The Digital Picture

"The Canon EF 28mm f/1.8 USM Lens is soft wide open. Stop the aperture down to f/2.8 and the center becomes sharp. Mid-frame performance (on a full frame DSLR) is softer - even stopped down. Corner performance does not degrade much (if any) over the mid-frame results. I'm disappointed by the sharpness delivered from this lens. It's not what I expected.  . . . read more

Canon EF 24mm f/2.8 Lens Review @ The Digital Picture

"The Canon EF 24mm f/2.8 Lens is rather flare-prone at wide aperture settings, but improves somewhat by f/8 and f/11. Distortion is mild, but some barrel distortion is present in the center and mid-sections of the frame. Some CA (Chromatic Aberration) is present in this lens, but it is not objectionable in comparison. Full frame body users will notice over 3 stops of shading in the corners of this lens . . . read more

Canon EF 24mm f/1.4 L II USM Lens Review @ The Digital Picture

"Obvious by now is that the Canon EF 24mm f/1.4 L II USM Lens is a weather sealed lens. Not so obvious is that this lens requires a filter for full sealing (like all other Canon non-Super Telephoto sealed lenses). 

Auto focus, driven by Ring USM (Ultrasonic Motor), is fast, quiet and accurate (mostly) - even in low light conditions. I say "mostly"

Canon EF-S 17-85mm 1:4-5.6 IS USM review @ DP review

"First announced in August 2004 to coincide with the launch of the EOS 20D, the EF-S 17-85mm F4-5.6 IS USM is Canon’s logical upgrade from the basic 18-55mm kit lens supplied with its APS-C dSLRs. With a 35mm-equivalent focal length of 27-136mm, it covers a decent wideangle to telephoto range, making it a useful ‘walkaround’  lens which will cover a wide range of photographic . . . read more

Canon EF-S 18-55mm 1:3.5-5.6 IS review @ DPreview

"Canon's 18-55mm 1:3.5-5.6 IS is the latest in its line of inexpensive DSLRs kit lenses which began with the original 18-55mm in 2003, as an accompaniment to the groundbreaking EOS Digital Rebel/300D (widely considered to be the camera which started the affordable DSLR revolution). The focal length range was chosen to be equivalent to the popular 28-90mm kit lenses then available for . . . read more

Canon EF 55-200mm f/4.5-5.6 II USM Lens Review @ The Digital Picture

"What you don't get with this lens is good build quality. The Canon EF 55-200mm f/4.5-5.6 II USM Lens has a very plastic-like feel to it. No distance window is provided. A plastic mount seals the low-end build quality rating. 

One of my favorite qualities of the Canon EF 55-200mm f/4.5-5.6 II USM Lens is its USM AF (Autofocus). It is fast and quiet. Well, at

Canon EF 24mm f/1.4 L USM Lens Review @ The-Digital-Picture

"The Canon EF 24mm f/1.4 L USM Lens is soft wide open, increasing in sharpness until very sharp at f/2.8. Corners are somewhat soft until stopped down some - becoming very sharp for a 24mm lens. Light fall-off is very noticeable at f/1.4, and, as usual, improves as the lens was stopped down. The 24 L exhibits noticeable amounts of CA.  . . . read more

Canon EF 28-200mm f/3.5-5.6 USM Lens Review @ The Digital Picture

"At 200mm, the short 17.7" (450mm) MFD (Minimum Focus Distance) creates a nice MM (Maximum Magnification) of .28x. So, close subjects are included in the 28-200's capabilities. 

Overall, the Canon EF 28-200mm f/3.5-5.6 USM Lens optically disappoints. 

Canon EF 28-135mm f/3.5-5.6 IS USM Lens Review @ The Digital Picture

"The Canon EF 28-135mm f/3.5-5.6 IS USM Lens' best feature (in my opinion of course) is its great focal length range. It is not hard to find uses for the 28-135mm focal length range. From family shots and vacation/travel use to landscapes photography to photojournalism, this lens can cover a wide range of your focal length needs. . . . read more

Canon EF 28-105mm f/4.0-5.6 USM Lens Review @ The Digital Picture

"If you take a Canon EF 28-90mm II USM Lens and stretch it to 28-105mm, you get the Canon EF 28-105mm f/4.0-5.6 USM Lens. They are very similar on many accounts other than the obvious similar appearance. 

Both have cheap build quality (plastic mounts, no distance window, wobbly objective ends ...). Both are light, small and inexpensive.

Canon EF 28-105mm f/3.5-4.5 II USM Lens Review @ The Digital Picture

"The Canon EF 28-105mm f/3.5-4.5 II USM Lens likes to hang out at 105mm. Expect gravity-zooming to occur when the objective end is pointing downward - no zoom lock is provided. 

Also a notch up from the econo zooms is a 7-blade medium-fast aperture that starts at f/3.5, goes to f/4 around 37mm and then to f/4.5

Canon EF 200-400mm f/4 L IS USM Extender 1.4x Lens Review @ The Digital Picture

"The Canon EF 200-400mm f/4 L IS USM Ext 1.4x Lens has inherited the built-in 1.4x extender (in concept at least) from the rare Canon FD 1200mm f/5.6 L Lens (picture on PBase.com). The 200-400 L is the first EF lens to receive built-in, switch on/off extender. 

I love the concept. A lockable lever is used to move lens elements into or out of the optical path. A unique bulge is present near the lens

Canon EF 28-90mm f/4-5.6 II Lens Review @ The Digital Picture

"The Canon EF 28-90mm f/4-5.6 II Lens is basically the same lens as the Canon EF 28-90mm II USM Lens. The exception is that it utilizes MM (Micro Motor) in lieu of Micro-USM (Ultrasonic Motor) for autofocus.The realized difference between these two lenses is that the Micro-USM version will focus a little faster and a little more quietly. And the non-USM Canon EF 28-90mm f/4-5.6 II Lens costs less.  . . . read more

Canon EF 70-200mm f/2.8 L IS USM Lens Review @ The Digital Picture

"I have received some comments on the ISO 12233 resolution chart samples for this lens - some think they are too soft at f/2.8. As I get time, I retest questionable results - Or even buy another copy of the lens to insure accurate but expectable results. I re-tested this lens and the Canon EF 70-200mm f/2.8 L non-IS USM Lens at the 200mm focal length using AF, MF and bracketing - obtained results were . . . read more

Canon EF 80-200mm f/4.5-5.6 II Lens Review @ The Digital Picture

"There is no FTM (Full Time Manual) focus and, in fact, there is no manual focus ring. You are expected to twist the extended portion of the Canon EF 80-200mm f/4.5-5.6 II Lens' barrel to manually adjust your focus distance. 

With the Canon EF 80-200mm f/4.5-5.6 II Lens, you also get very cheap build quality. Included is a plastic mount, excluded is a

Canon EF 16-35mm f/2.8L USM review at SLR Gear

"This is one of Canon's famous "L" series lenses, but we found its performance at maximum aperture a little wanting. Depending on the focal length, it ended up somewhat soft when shot wide open, either in the corners, or on one side or the other. In a lesser lens, the degree of softness here would probably pass with little comment, but at a street price north of (US$)1400, we think photographers have a right to expect better . . . read more

Canon EF 55-200mm f/4.5-5.6 II USM review at SLR Gear

"As noted above, this is Canon's "budget tele zoom," intended for SLR shooters on a budget, but who still want a decent mid-range tele zoom. (Actually, this is a pretty long zoom on dSLRs with APS-C size sensors, like the Rebel series and the EOS-20D.) Given its bargain price, it actually doesn't do too badly . . . read more
