Spoli58, a FredMiranda forum member, posted an extensive report on Canon EF 70-300mm f/4.0-5.6 IS USM and wrote:

“- Overall impression: good quality optics, better than EF 55-200, probably not L grade but not too far if you consider the price and the class of this lens.
- In the range 70 to 85mm @ F8…F11 the results look similar to my EF-S 17-85mm IS USM, surprisingly sharp at the corners (hard to see real differences in terms of sharpness and geometrical distortions) — great outdoor lens in good light conditions.
- At F8 the image is sharp for almost the entire focal range — at the long end (between 200-300mm) the image looks a bit soft without affecting the resolution — maybe it’s just the fact that I’m using a cheap tripod and IS turned on rather than a rock solid tripod, mirror lock and no IS.

Ian Andrews posted his Canon EF-S 10-22mm f/3.5-4.5 USM Lens test and wrote:

” The ultra-wide group to which this lens belongs has gone a long way towards overcoming the biggest drawback of cropped sensor dSLR’s, that of lost angle of view at the wide end. Being newly designed, it has addressed all of the other problems that have been thrown up by digital sensors and optically, if they had stopped at 20mm there would be very little to pick up on. The one slight disappointment is the build quality when looked at in terms of the price, as the cost is more than some ‘L’ class lenses and is the biggest barrier to owning this lens after the need to have one of the limited cameras it will fit on.

The negative points are: Price, Restricted fitting (Won’t fit D30/60 or 10D), Lens hood is an optional extra.”

Mark D. Segal compared both Canon EOS 24-105mm F/4 L IS USM with Canon EF 28-135mm IS USM and wrote:

“My findings and comparison of key specifications: Insignificant vignetting with either lens; The L lens has generally superior contrast; The L lens displays generally less chromatic aberration, but some exists in the same places where the 28~135 had more; At 105mm it is hard to see much difference in resolution even at 100% magnification; At 28mm and 50mm the differences of sharpness/resolution are obvious even at f8, which should be in the range of the “sweet spot” for both lenses; 24mm really expands the image area considerably compared with 28mm; at the telephoto end 105mm is enough for me, considering that I also have a 70~300mm; Maximum telephoto aperture of f/4 versus f/5.6 (twice the amount of light).”

Travis has posted his samples of his new Canon EF 24-105mm f/4L IS USM and commented:

“My personal opinion at this point is that the lens is plenty sharp at 105mm, though at 24-60 this lens is SUPER sharp! The build quality is great and my initial few shots with IS have shown a noticeable improvement over the 28-135 IS I used to use. Focusing is fast and quiet, and the lens feels just right on my 20D. At this point, I’m thinking it’s definitely a keeper.

So is it sharper at 40-55mm than 105mm? In a word, yes. Sharpness at 105mm and F4 still isn’t bad, though. “

WSlam has just posted his comparison shots from Canon 17-40mm F/4L, Canon 24-70mm F/2.8L and the new Canon 24-105mm f/4 L IS at his website. Here’s his comment about the test:

“Due to poor weather here in Hong Kong, I had to take these indoor. The camera (EOS20D) was mounted on a tripod. White Balance was obtained from a grey card and applied during RAW conversion. All photos were shot in RAW, connverted into unsharpened JPG then resized and sharpened in PhotoShop CS2 (Smart Sharpen 80, 0.8, Lens Blur). Everything was done in batch, so all the files received the same ‘treatment’. Full Size (zipped) are unsharpened. Focus point is on the dog’s right eye (the one on the left).”

Some sample shots from Canon 10-22mm and Sigma 10-20mm with 100% crop have just been posted by Dougal in Canada.

Here’s what Dougal says about his test:

“My test limits the Canon to 20mm and F-stops identical to those of the Sigma. For simplicity I’ll only provide wide open (obviously the Canon is stepped down a little) results.

All images were processed in CaptureOne with no sharpening and Identical exposure and white balance settings. ISO setting for all shots was ISO100, F4 (10mm) shots were shot at 1/800s and F5.6 (20mm) shots at 1/400s. A cable release was also use to operate the shutter.”
