As promised, I divested myself of the Canon 28-90. I made some attempts to use the Canon 35-80mm F/4-5.6 III, which is slightly less bad but still awful. Color transmission and contrast are both lacking. Distortion is present, but far less so than the 28-90.
The MV museum's parking lot. 35-80 @ 64mm, F/18, which is probably well into diffraction territory. I worked this image over pretty thoroughly in Luminar 4 and Photoshop.
A few feet back, also 64mm and F/20 which is ...excessive.
EDIT: Hours later. One goddamn wrong link fixed.
Sweetened Water Farm, across from my house. Golden hour sun. Less editing than one might think (contrast enhancement mostly). 80mm, F/18.
That famous little shack, which is one of my regular test subjects. 35mm, F/14. Much work done in Photoshop correcting distortion, boosting contrast and colors. That's probably it for me and the 28-80. It manages to suck less than the 28-90, which is damnation with the faintest of praise.
Tune in next time when I take the Nifty Fifty to the famous Lucy Vincent Beach and the Gay Head Cliffs (yes, that's really their name.)
