So do these photos look unusable to you? (rhetorical question) I recently got a mirror lens – the Tamron 55BB 500mm F8 – to be exact. Many dislike mirror lenses because they can be finicky to work with due to the fixed F8 focal ratio, shallow depth of field, and long focal length. All of which makes getting focus and capturing sharp images challenging. These lenses also have very distinctive bokeh due to the obstruction from the secondary mirror. Can you see the “donuts” in these photos.
I quite like these photos. They remind me of old film photographs. As you can probably tell from this blog, I am not one who is too fussed about “tack sharp” as a photographer. If a photo is acceptably in focus, I’m good. I do have to say that this lens does really need daylight. Low light would require a tripod and long exposure times to compensate for the F8 aperture.
