I use minimal or no sharpening with the Aptus 75, especially when using a digital lens. I use a bit with film lenses, but it depends on the usage. For providing files to clients I use none or very little.
One of the main advantages of something like the Aptus 75 is that you dont really have to sharpen, or correct distortion in the images, which is necessary with the shots I used to get from the Canon. This helps reduce the longer workflow time of processing the bigger files.
I think that the apparent sharpness of files is something that is part of the creative control with digital, a softer look might be just a different aesthetic. Once you have the detail of 33+ megapixels there is plenty of detail, perhaps sharpening just makes it look different.
Looking at older classic photos, they were mostly far softer than would be acceptable today, but they have their own charm. Perhaps once our cameras are as good as we need, we can start to use sharpness as one more variable in creating an image. I'm wondering if we arent going to get to the point (if we arent there already) where are printers are what are letting us down. Lightjets print at under 300dpi, but an 8x10 from an A75 contains more data than that. Similarly inkjets provide a detailed print at 180-240dpi and dont seem to benefit from more data.
