The reason it's questioned is three-fold: 2 - The image size is wrong for the 30D - original size is 4368x2912 which is the 5D file size at 12.7 megapixels (30D is 3504x2336 8.2mp). I shot with a 30D and a Nikon D200 at the same time. First 30D I'd seen in Toronto. It wasn't a 5D. No processing other than an increase in brightness. OMG...this ought to be good for a laugh... RichA, please explain to everyone the discrepancy in the pixel count. Then after fumbling for an excuse with that, please explain the 6MB file size from a Canon 30D jpg which is typically a lot smaller at about 3.5MB in size. And for some more fun, have a look at this image from your own page: http://www.pbase.com/andersonrm/image/57655520 Notice how it _CLAIMS_ to be a crop from a 30D, yet the accompanying info and exif both state it's from a 5D. Can you _BE_ any more stupid? I think you can...c'mon, you can do it. |

Sharpest Canon 1.6 crop lens

You can't use the 17-85 wide open, and even when stopped down to improve sharpness, it still lacks contrast and it has nasty CA at the wide end. The 17-85 is a poor performer for the price. It has the advantage of IS and a wide zoom range for convenience, but that's it. Optically it's nothing to get excited about, and the cheap $100 18-55 kit lense is about as good as the 17-85. But definitely NOT for pro's. I've read several reviews, from good to bad, and found out that all bad were compared to pro lenses, while all good were estimated as "very good for the price" so not as a comparison with pro lens, but rather a relative conclusion. Not comparing to more expensive lenses, the cheaper 28-135/3.5-5.6 IS is better than the more expensive 17-85/4-5.6 IS, plus that covers full frame. http://digitcamera.tripod.com/#slr good one...only wide end could be a bit wider... |
