Canon TS-E 17mm f/4 L Tilt-Shift Lens Review @ The Digital Picture

'Another differentiator visible above is the amount of vignetting present in the corner images. The Canon TS-E 17mm f/4 L Tilt-Shift Lens controls vignetting very well for a 17mm focal length. Full frame body users are going to notice about 2 stops of darkening in the corners at f/4. Comparing this figure to the 2.5 stops for the even wider aperture Canon EF 16-35mm f/2.8 L II USM Lens at f/4 or the 4 . . . read more

Canon EF 24mm f/2.8 review at Photozone

"Released back in 1988 the Canon EF 24mm f/2.8 is one of the oldest Canon EF lenses but it is still part of the current line-up. On APS-C DSLRs such as the EOS 350D/Digital RebelXT (as usual used for testing) the moderate ultra wide-angle lens is transformed into a moderate wide-angle equivalent to about . . . read more

Canon EF 35mm f/2.0 Lens Review @ The Digital Picture

"At similar apertures, the Canon EF 35mm f/2.0 Lens is similarly sharp in the center to my Canon EF 24-70mm f/2.8 L USM Lens at 35mm. However, the 24-70 L was much sharper in the corners even on a 1.6x FOVCF body. 

At similar apertures, the Canon EF 35mm f/2.0 Lens was clearly sharper than my Canon EF 16-35mm f/2.8 L USM Lens at 35mm. The

Canon EF-S 18-55mm f/3.5-5.6 Lens Review @ The Digital Picture

"There is no distance window on the Canon EF-S 18-55mm f/3.5-5.6 Lens. The tiny manual focusing ring is barely usable and is located on the end of the extending objective end of the lens. There is no USM focusing motor (on the kit model) which means there is no FTM (Full Time Manual) focusing.  . . . read more

Canon EF 24mm f/2.8 review at SLR Gear

"Canon's come a long way since 1988, as the sharpness profile for the 24mm ƒ/2.8 will attest. Wide-open performance exhibits quite a bit of corner softness, on both sub- and full-frame camera bodies. The fact that our review sample is slightly de-centered doesn't help matters.

Canon EF-S 10-22mm f/3.5-4.5 USM review at SLR Gear

"The Canon 10-22 EF-S is a surprisingly high quality optic, although one would perhaps expect that, given its premium pricing. It does unusually well wide open, although some softness creeps into the corners of the frame at its longest (22mm) focallength. It's "sweet spot" of maximum sharpness ranges from f/5.6-8.0 . . . read more

Canon EF 70-300mm f/4.5-5.6 DO IS USM Lens Review @ The Digital Picture

""A zoom lock switch (above) on the Canon EF 70-300mm f/4.5-5.6 DO IS USM Lens is a nice feature - It prevents the lens from extending when you don't want it to. The trade-off is that it makes the lens slower to put into action. Use it when you want to, don't use it when you might need to grab a quick shot.  . . . read more

Canon EF 24-105mm f/4L IS USM review at SLR Gear

"This has been one of the most-requested lenses on the site for us to test, so we're very pleased to finally be able to share our test results with everyone. - And what a lens it is!

Canon EF 24-105mm f/4 L IS USM Lens Review @ The Digital Picture

One of Canon's greatest hits ever. Many photographers around the globe have this lens practically glued on their 5D markII's. Plastic but strong construction, excellent image quality, really versatile zoom range, and a fast IS/AF system.

Canon EF-S 17-85mm f/4-5.6 IS USM Lens Review @ The Digital Picture

"Why put Image Stabilization into a wide angle to short telephoto zoom lens? For the same reason you put it into telephoto lenses - to reduce camera shake. Since the Canon EF-S 17-85mm f/4-5.6 IS USM Lens has third generation IS, it can be handheld up to 3 f-stops lower than a non-IS lens at the same focal length. Granted, a wide angle lens can be handheld at lower shutter speeds than a long . . . read more

Canon EF 15mm f/2.8 Fisheye Lens Review @ The Digital Picture

"Close subjects tend to be soft at f/2.8 and become steadily sharper through f/8. Distant subjects were sharp wide open and improved little with the lens stopped down. What was most noticeable to me was the relatively excellent corner sharpness even on a full-frame body. The Canon EF 15mm f/2.8 Fisheye Lens easily bests the Canon EF 14mm L USM Lens, the Canon EF 16-35mm L USM Lens . . . read more

Canon EF 24-70mm f/2.8L USM review at SLR Gear

"As anyone who's shot with one will attest (see the user reviews below), the Canon 24-70mm f/2.8 lens is just an exceptional optic. This was clearly evident in our DxO tests as well. On the sub-frame EOS-20D, the lens was tack sharp across the entire frame wide open, from 24-50mm. At 70mm, it softened slightly at . . . read more

Canon EF 100mm F2.8 L IS USM Macro Lens Review @ d preview

"Back in July, Canon took the distinctly unusual step of announcing a new technological development completely in isolation from any products. The subject was a novel 'Hybrid' optical image stabilization system designed to compensate for two distinct types of camera shake. You can read more about it here, but in essence the stabilizer is different from existing systems, which only detect and correct . . . read more

Canon EF-S 15-85mm f/3.5-5.6 IS USM Lens Review @ The Digital Picture

"Yes, there are lenses with longer focal length ranges, but few go as wide as 15mm and they usually offer compromises - typically where it hurts the most - image quality. And image quality is one area where this lens delivers. 

This is not a Canon L Series Lens (as of this review date, Canon has not released an EF-S L lens), but the Canon EF-S 15-85mm

Canon EF 100mm f/2.8 L IS USM Macro Lens Review @ The Digital Picture

"What isn't new is the old standard Canon side-pinch-only lens cap. Canon really needs to update this design to the center-and-side-pinch caps used by most competitors. The long, narrow installed hood (included) makes it very difficult for me to access the lens cap. Adjusting a circular polarizer inside the hood is nearly impossible as your hand completely blocks the light. On the other hand (and . . . read more

Canon EF-S 18-200mm f/3.5-5.6 IS review at SLR Gear

"The 18-200mm, like all ''vacation lenses,'' must make concessions to balance optical performance, weight and price. In this regard the Canon lens is not immune. Our copy of the Canon 18-200mm ƒ/3.5-5.6 IS seemed to be very slightly out of alignment, with the effect most noticeable at 18mm (the sharpest region

Canon TS-E 24mm f/3.5 L II Tilt-Shift Lens Review @ The Digital Picture

"Vignetting is very well controlled - You might notice a little vignetting in full frame corners at f/3.5, but overall, nothing to worry about. Performance is very similar to the EF 24 L II in this regard (at the same apertures). 

CA (Chromatic Aberration) is extremely well controlled - less CA than the EF 24 L II and much less than the original TS-E 24mm L.

Canon EF 35mm f/1.4 USM L review at Photozone

"Released back in late 1998 the Canon EF 35mm f/1.4 USM L is one of several ultra large aperture prime lenses in the Canon lens lineup. It's one of the more frequently discussed specialty lenses in the community and often compared to its cousin - the EF 24mm f/1.4 USM L II. Both belong to the L (Luxury) league within the system.

Canon 70-200mm f/2.8 L IS review at photodo

"The weight and build of this lens is what makes it really stand apart from the rest. The construction is second to none and the weight is accounted for in the materials used for the solid but pipe-like barrel. The lens remains the same length and orientation through all settings, making it easy to use filters on the 77mm thread.

Going away from the camera body you first come to the tripod collar. In front of that is the zoom ring

Canon TS-E 24mm F3.5 L II Lens Review @DPreview

"PMA 2009 was a show distinctly light on noteworthy announcements, but one of the most technically interesting developments may well have slipped under the radar of many enthusiast photographers. Canon introduced two new perspective control lenses to its TS-E ('Tilt and Shift for EOS') range, in the shape of the TS-E 24mm F3.5 L II and the TS-E 17mm F4L. But while the latter quite . . . read more

Canon EF 180mm f/3.5L Macro USM review at photodo

"This lens has the well-built feel and finish of Canon’s L range and gives the impression that it will last a lifetime. It is supplied fitted with a slightly chunky looking tripod collar that can only be removed with the lens off the camera. A control panel on the left of the barrel, just in front of the collar, contains two switches, one for the AF/MF and the other a focus limiter that can switch from the full range of 0.48m-

Canon EF 28-300mm f/3.5-5.6 L IS USM Lens Review @ The Digital Picture

"The Canon EF 28-300mm f/3.5-5.6 L IS USM Lens is a variable maximum aperture zoom lens. Maximum aperture starts at f/3.5 at 28mm, narrows to f/4 near 50mm, to f/4.5 near 55mm, to f/5 around 70mm and finally to f/5.6 approximately 115mm. Slightly annoying to me is that AV and M modes gives two clicks for f/5 at 70mm. These maximum apertures indicate that the 28-300 L is not a "Fast" . . . read more

Canon EF 75-300mm f/4-5.6 IS USM Lens Review @ The Digital Picture

"Like the Canon EF 75-300mm III USM Lens, the Canon EF 75-300mm f/4-5.6 IS USM Lens is soft wide open at all focal lengths. Sharpness decreases as it zooms from 70mm to 300mm. However, the corners are softest at 70 and getting better by 300. 

Corner and center softness decrease as the Canon EF 75-300mm f/4-5.6 IS USM Lens is stopped down. 

Canon EF 17-40mm f/4.0 L USM Lens Review @ The Digital Info Picture

"The Canon EF 17-40mm f/4.0 L USM Lens ships with a Canon EW-83E lens hood and a Canon LP1319 soft lens pouch. The shape of the hood (very wide and very short) makes one question whether it actually helps. It does almost nothing for lens protection - and nearly nothing for image quality when used on a 1.6x FOVCF body. It also makes storage inefficient. With the hood removed, the 17-40 . . . read more

Canon EF 24-70mm f/2.8 L USM Lens Review @ The Digital Picture

"The Canon EF 24-70mm f/2.8 L USM Lens' MFD (Minimum Focus Distance) is about best (shortest) in class even without an extension tube. This short focus distance provides a very nice MM (Maximum Magnification). While not close to a 1:1 macro lens, the 24-70 L can take nice flower shots, product pictures ... Although it is not compatible with Canon's extenders, extension tubes will extend . . . read more

Canon EF 300mm f/4 L IS USM review at photodo

"As a ‘white’ L class lens this Canon offering is built to last. The metal bodied barrel is of the ‘drainpipe’ type, being almost constant in diameter throughout its length. The slightly narrower collar just in front of the mount allows finger room next to the camera’s grip and on the opposite side carries the two switches for AF/MF and focus limiter that allows 3m to infinity and the full scope of 1.5m to infinity.

Canon EF 1200mm f/5.6 L USM Lens Review @ The-Digital-Picture

"According to Mr. Westfall, "Canon has not released specific production quantities, but according to my understanding, less than 100 of these lenses were made." Rumors put this number closer to 20, but ... no one who knows is releasing the actual figure. The price? If you need to ask ... you can't afford it. The original price was 9,800,000 yen - that was MSRP $89,579 in the USA. And "no discounts" according to Mr. Westfall. The model I reviewed (in excellent condition) has a $120,000 price tag hanging on it. That's right - it costs more than a small house in the country." . . . read more

Canon 35mm f/1.4 L USM review at photodo

"Prime lenses can seem very simple to use after some of the modern zooms and the simplicity eases the achievement of build quality. A single focussing ring in front of a classic distance window that is marked with a useful depth-of-field scale pretty well sums up this lens. The only other control on the lens is the switch that changes the focussing from Manual to Autofocus.

The lens seems a little large compared to say, an 18-55mm zoom, but this is due to the wide aperture that

Canon EF-S 10-22mm f/3.5-4.5 USM Lens Review @ The Digital Picture

"At the super-wide 10mm setting, my tripod is barely outside of the frame. At 22mm, the framing is similar to what many general purpose zoom lenses can deliver at their widest focal length - which is likely similar to the 17mm or 22mm examples.
