A few days ago I started a thread Anyone fancy a walk down some Devon lanes (sorry to you gear buffs, lots of images) and one of the responses (from Nic, aka Luckypenquin) queried the "tight cropping" of some of the images. I explained that I was using a 15mm lens (on a m4/3 camera) and that the location was such that I was physically unable to get further back from the subjects.
I've since taken another walk in that location and took the opportunity to take some photographs with a 12mm f/5.6 lens. Whilst I didn't always manage to stand in the exact same position as the previous shots I hope that I was close enough that the results are such that the difference in field of view of the two lenses is obvious, and that you can see how it affects the feeling of the resulting images. The 12mm image is shown first followed by its corresponding 15mm image. Again I stress there has been no cropping of width of the camera raw image, just a height crop from the original 4:3 format.

I would have to say that the shots with the 12mm focal length lens do tend in my opinion to set the subject material in context better than those taken with the 15mm lens. The bridge scene has of course been taken in landscape and I think being able to include the curving parapet leads the eye into the photograph more dramatically than the previous version.
I think the 12mm f/5.6 Voigtlander lens has produced images capable of being printed with little loss of image quality compared to the 15mm lens. Unfortunately my printer has thrown a wobbly and is printing a borderless block with one of the coloured inks overlaying the A4 print At a smaller print size the problem doesn't appear, all very odd and just when I've purchased a full new set of bulk coloured ink for it Therefore, despite many attempts I've not been able to produce any prints for a direct comparison at print size and resolution to judge the image quality of the two lenses, but I have a feeling they are not too far apart. I did use stronger sharpening, and indeed a different technique on the images taken with the 12mm lens which does appear to produce a softer image.
I trust this has been of some interest to some of you. I felt compelled to carry out this comparison following Nic's comments.
