Огромное спасибо :beer: ,
но 2я ссылка про б-ф фокус камеры а не объективы…
3я ссылка- известная методика и табличка (в pdf)
В 1й ссылке есть немного инт. ин-фы.
Только про одну линзу относительно подробно: 24-85:

"I decided to try this test with my new 10D and 24-85mm lens. I considered the exercise just another part of my learning curve as I continue to master this camera. I put the camera on a tripod, ~ 19" (minimum focusing distance) from the center of the chart, at the prescribed 45 degree angle, and used the self-timer to trip the shutter. My results:
@ 24mm, F/3.5; auto & manual focus: DOF normal :rolleyes:
@ 62mm, F/4.0; auto focus: DOF slightly forward
@ 62mm, F/4.0; manual focus: DOF normal
@ 85mm, F/3.5; auto focus: DOF forward
@ 85mm, F/3.5; manual focus DOF slightly forward
I chose 62mm as the midpoint, as this was the closest I could zoom in and still obtain an F/4.0 aperture. In all cases, the target center line was sharply in focus, so I'm content. I should qualify myself by stating that, until last week, I haven't touched an SLR since the 70's; and have been using AF compact 35mm and digitals for the last 12 years. Also, I've gleaned a ton of current information from this site in the weeks preceeding my purchase, and I happily linked through to one of Photo.net's featured vendors to make my purchase!"

Пропущены фок. раст-я: 35мм., 50мм.
Выводы по 24мм ф. раст. вызывают сомнения в результате богатого опыта общения с 24-85…:fingal:
Интересуют тесты на б.-ф. фокус на РАЗНЫХ фок. расстояниях линз.:pray:
