What I hope for and expect with any lens, especially L lenses, is for the actual images they produce, using whatever corrections they are designed for (optical, digital, or both) to be really good. Since the images from the VCM lenses are not just really good, but actually outstanding, I also think they are a remarkable accomplishment. I own and use four of them (24, 35, 50, 85), so I actually know what I'm talking about (unlike people who tiresomely scream "but digital corrections, but digital corrections" over and over and over, without actually owning and using the lenses). When I bought my 50 F1.4, I thought I might hang onto my RF 50 F1.2, which is a truly wonderful lens. However, I just didn't find myself using it. The results from the VCM version are just as good, no-one notices the 1/3 stop difference between F1.2 and F1.4, and the VCM version is so much smaller and lighter. So I've just sold my F1.2. The latest, which is the 85 F1.4, is my favorite 85 ever. It's just superb. You can, of course, stick your head in the mud, ignore the fact that designing lenses for digital corrections (which the VCM lenses employ to a greater or lesser extent, depending on which lens we're talking about--the 85 probably the least) makes possible not just particular body designs but also the kinds of optical performance that would be hard, if not impossible, to achieve with optical corrections only, and thereby miss out on some fabulous lenses. Your choice.
