The A35-105 is a nifty lens, but can be a little finicky when the light is too direct or bright. Contrast is one thing and a little layering of brightness from center going toward edge. Best when light is angled closer to 90 degrees or higher.
The interpolating expansion algorithm that I have been using is bicubic based and seems to bring forth the image with minimal distortion. My impression is that this may be included in many post processing software packages. I use Corel software. You have to denoise and sharpen carefully. The enlargement algorithm expands the noise, also. If you try to sharpen too freely, you will generate halo effects on the edges of contours and the skyline. I look at enlarged sections to make sure the overall image will be reasonable. I have used it to enlarge K200D 10MP, K-5 16MP, and K-3 24MP images also. But not that large.

My issues with the A35-105 have been on low-contrast scenes, so quite the converse of yours. Thanks for the information on the enlargement algorithm.

It’s a lovely piece of work, and optically it’s a good lens to add to your collection. I find using a manual focus lens occasionally slows me down, which is good for the sort of shooting I usually do.
