Canon 35mm f/1.4 L

The Canon EF 35mm f/1.4L USM is a large-diameter wide-angle lens with f/1.4 capability that optimises brightness. It is the successor to the EF 24mm f/1.4 USM and further complements the Canon L-series of wide-angle lenses. The optical system includes a polished aspherical lens along with a floating element, providing high image quality with outstanding correction for both wide f/1.4 aperture and aberration effects and outstanding definition over the entire image area. In addition, the lens’s ring USM and silent AF operation make it an outstanding L-series lens for both professional and advanced amateur users.

Canon 10-22mm VS Sigma 18-50mm @ 18mm

Klam has posted his sample test of Canon 10-22 and Sigma 18-50mm at FredMiranda forum and commented:

“I conducted the test on an overlapping focal length of 18mm. Since I frequently shot my 18-50 at 18mm, I knew I should try to find something wider, which is the reason that I picked up the 10-22.These 100% crops were shot on tripod, delayed timer, RAW straight converted using Canon DPP.

Both lenses are very decent in the centre. The Canon doesn’t seem to show as much improvement and is quite good “wide open” at f/4.0.

The Sigma looks very soft in the corners at f/2.8. At f/4.0 it improves very slightly but still seems soft. Everything is ok by f/8.0. On the other hand the Canon shows a lot of corner detail even at its “wide open” setting of f/4.0. Overall the Canon is a lot better in the corners.”

Canon EF 70-300mm f/4-5.6 IS USM – Review @ BobAtkins

Bobatkins.com tested and reviewed the Canon EF 70-300mm f/4-5.6 IS USM and wrote:

“..lens is sharper at f5.6 than the old lens was at f8. Don’t get carried away though, since despite using a UD glass element, it’s still not as sharp as the 300/4L. Even the new lens benefits by stopping down to f8. With an EOS 20D and at f8, on real world targets, image quality almost approached that of the 300/4L is some shots. However on resolution test charts the 300/4L showed higher contrast and resolution. Still, the performance of the new lens is pretty good.

Canon 70-300mm F4.0 - F5.6 IS USM

..the new EF70-300/4-5.6 IS fits the bill as an ideal “walking around” lens for nature, travel and sports photographers. It’s small enough and light enough to carry around as part of a kit (it would pair well with an EF-S 17-85/3.5-5.6 USM) and the image quality and stabilization are improved enough over the old lens to justify its additional cost. ..”

Comparison of Canon Midrange Zooms

Acapixus did a comparison of Canon EF 24-105/4.0 L IS USM versus a EF 28-105/3.5-4.5 USM and a EF 28-135/3.5-5.6 IS USM versus Canon EF 17-35/2.8 L USM versus Canon EF 50/1.4 USM versus Canon EF 100/2.8 USM macro.

The comparison was shot at ifferent focal length and at different f-stops using a Canon EOS 10D set at ISO 100. The camera was tripod mounted. Images were captured as RAW and converted to 24 bit TIFF files using DPP 1.503. Sharpness was set to 0 (no sharpening) and no other postprocessing has been applied to the images. 200×200 pixel crops were excised from the centre and periphery and saved as TIFF prior to conversion as JPEG files
