Originally posted by Dartmoor Dave I know I've made it seem like a deranged act of wanton destruction, but it really wasn't. It was a carefully considered decision. I've got a lot of experience with vintage lenses, and I'm very familiar with different kinds of front element marks and scratches, so my goal was to simulate the effect on contrast and saturation that comes from decades of heavy cleaning marks.
The lens:
A quick test shot from early this morning:
The only processing is to set black and white points. The whole point of this is to get the look I want optically rather than Photoshopically. I reduced it to web size without any sharpening, so it looks softer than it actually is, and I'm very happy with the way the lens's hard edges have been (literally) sanded away.
And anyway, somebody has to provide some comic relief around here.
Dave, you have reminded me that I have a 58mm Asanuma Softon filter that I bought was back in the 1980s and I only ever used it once or twice way back then. I have a 52->58mm step up ring and I will give it a try tomorrow on my 18-55mm WR (on my K-3) to show you what effect it produces. I did a quick Google search and I don't think they are still available but that is not a concern for you because you have already found a DIY solution.
I still feel a little uncomfortable when I look at what you did to your lens but that is just because I treat my gear with the utmost care. You are at liberty do whatever you want with your gear. As long as it does what you want it to do then that is all that matters.

I had a few moments to spare and I did the test with my K10D (so that I could post the images here without guilt!). Images are JPGs SOOC with only resizing for web (2048 pixels on long edge).
The difference is pretty obvious but I not sure if that is what you were after, Dave. I think the filter lived up to its name.
K10D, SMC Pentax-DA 18-55mm F3.5-5.6 AL WR, no filter.
