аж 200 с лишним листов (практически все кто купил и тестил эту линзу нашли проблему бякфокуса) можно конечно посылать в сервис (50$ - каждая посылка со страховкой)
только судя по форуму это мало помогает
люди просто мирятся с этим и как то привыкают к этому
-----------у меня вопрос такой если вероятность найти нормальный экземпляр (брать буду по интернету) могу конечно менять бесконечно но это те 50$ (insurance and confirmation) за каждую посылку.

When shooting at close to minimum focusing distance, AF seems spot-on at f1.2, but way off at f3.2.
Both shots with center focusing point, focused on the D in DNK. First shot is f1.2, second one is f3.2. I shot about 5 of both, with the same results.

а этот вроде справил - правда с третьего раза
It was sharp enough that I sent my first one back 3 times to Canon trying to get them to fix it where it would AF as well as it would manually focus...
I was impressed and really wanted it to work right.
One of these shots was with the old 50L f/1.0...so don't confuse it....it is clearly labeled....I included it in the series for comparison.
But this sequence was essentially manually focused...and shows that the lens was fairly sharp through all apertures....I focused once and left AF off for all consecutive shots..

Well mine was one of the UU1100 and I returned it. It displayed very irregular focusing issues. Sometimes it looks ok and sometime it back focus very badly. I returned to my dealer and he did their own test and confirmed my issues. I decided not to get a replacement.
Here is a sample. I focus on my son's left eye and see how sharp his right eye is. Would you believe it. I have confirmed the focus point as well so I did not make any mistake about which eye I focussed on. I was totally shocked when I saw this result. I really didn't want to return the lens as I keep convincing myself it was my focusing error until I did more test to display this inconsistancy

Логических расуждений и сылок на тесты я не хочу - нужно только мнение довольного владельца этой линзы (если здесь такой есть)
