DA lenses on Full Frame: Test Shots

[falconeye]

Hi everybody,

I would like to open up a thread dedicated to one topic:

DA lens on Full Frame: a sticky test shots thread.

This thread shall be dedicated to test shots of a DA lens mounted to a full frame body (e.g., a film camera body). By test shot, I mean shots dedicated to evaluate the performance. Shots of ordinary subjects aren't suitable to this task, normally, and should not be posted. So, these are the rules:

• K mount lens dedicated to the APS-C form factor is used.
• Image is taken full frame 36mm x 24mm.
• Lens hood was removed.
• The aperture used is specified (note that film cameras don't record EXIF...).
• Sample image shows the entire field of view.
• Sample image(s) show(s) corner, border and center performance at 10MP-100% (multiple crops, or single not-resized image).
• The subject is such that resolution and vignetting at the borders can be compared to the center.

The idea behind this thread is obvious: To compile enough data to assess the spectrum of available lenses for a forthcoming full frame DSLR in K mount.
