I used my Pentax Z-1p 35mm film camera.
For some tests I also used my Kenko P-AF 1.4x TELEPLUS MC4 teleconverter.
I first shot a wall of my house in daylight, both with and without a tripod, and, except for the two longest lenses, without a lenshood (except where one was built-in).
But I mostly shot a simple target indoors illuminated by the modelling lights of two studio lights, using a tripod but not a lenshood (except where one was built-in). I used autofocus, except for two SDM-only lenses where I had to manually focus. I used aperture priority throughout. No filters (of any kind) were used. When I used a tripod, hence for all shots of the target, I used 2-second delay (which raises the mirror in advance) to reduce camera shake.
I made some errors while shooting, for example sometimes leaving the lenshood on when shooting the wall, and cases of camera shake and inaccurate focusing. It is unlikely that I will ever re-shoot those cases. This was a one-off exercise, and mostly I've learned what I set out to learn.
I converted these to JPEGs of the same resolution, hence about 4 MB or so each. I superimposed a rectangle corresponding to the size of an APS-C sensor onto each image so that the edge and corner definition of the lenses in their designated environment can be seen. These are the JPEGs linked to from the pages-per-lens.
There are 99 images, 45 of which used a Teleconverter:
- 18 of a brick wall with just the lens
- 10 of a brick wall with lens plus 1.4x Teleconverter
- 36 of a simple target with just the lens
- 35 of a simple target with lens plus 1.4x Teleconverter
