That's true and thanks for the reminder. I've still a full article to write about that. Examining resolution, typical corner resolution for full frame lenses and what film can resolve in the center and all this.
But here is a quick and dirty upload of three focal lengths of the DA*60-250 fully open on Film.
Focal lengths in order:
- 60mm
- 60mm f/4
- 135mm f/4
- 250mm f/4
Note that TMax 100 is a film with hard gradation and will exagerate any vignetting effect in the corners. Also note that the black effect at the left edge and in the lower left corner is shadow on the wall. Also note that I cropped the scans (with 3/2 ratio for 24x36mm) to get rid of the black borders. The scan area may have been slightly greater by a few pixels.
Vignetting is most visible at long focal lengths and fully open aperture. But vignetting is always partial only, i.e., can be corrected. More cumbersome is a certain softness in extreme corners at the short end and fully open aperture. Both effects rapidly disappear when stepping down.
In order to set all this into perspective, I have to compare results with a dedicated full frame lens. I already measured the FA*300/4.5 (and previously, the DA*300/4) but didn't find the time yet to publish everything side by side.
