>A case could be made for zoom lenses and digital press publishing. You can >correct for the loss of sharpness in Photoshop®. First, you must realize that you cannot correct for loss of sharpness in Photoshop. When you "sharpen" images in Photoshop, you are adjusting contrast in adjacent pixels, giving the perception of increased sharpness, while actually degrading the overall image. There is no real way to sharpen images. This is kind of besides the point though. Although the digitial world is interesting, and has its place, my comments were not made with digital imaging in mind. >However the real test of how good is your zoom lens is when you blow it up on actual photographic paper, >(i.e. 8x10 or 11x14 for 35mm). Okay, how many of you have blown up your >slides and negatives to see if your zoom lens is sharp? I have 4 16x20 full frame prints in my office, that considering the 16x20 size is larger than recommended for 35 mm film and that they are third generation (35 mm film, 4x5 internegative, and 16x20 print), their sharpness is excellent. (to make a long story short, I use internegs instead of Cibachromes, because I have maintained ties with my former employer, and benefit from very low costs as a result, and they cannot make Cibachormes, er, IlfoChromes). Two of these shots were taken with a 2x teleconverter as well, with very good results. Before I became a light rail consultant, I worked at a custom processing shop and studio for nearly 10 years. I have some decent experience, and I am certain what I have is proof in the pudding. This is not to say that every image I shoot is razor sharp, it is not. Some of my favorite images are not perfectly sharp. It is also not to say that what I have experienced with my lenses is reflective of everyone else. It is not. But I can say with a great deal of certainty, and obviously with support from many individuals, is that the quality and sharpness of today's zoom lenses from the major manufacturers is excellent.
