May 31, 2015 15:01 | #499 xmark402 thank you for the tests. There is some CA present, even at the 1280 px on the long side photos. At 100% crop it would be 4 times wider, probably similar to the old MkII. Gerry

Everything points towards replacing a perfectly good EF 50 f1.8 MkII with the STM! ![]() Ok, I did some comparison shots with the 50 and 85 1.8. Everything was shot at f1.8 with a 6D. Nothing is edited except for cropping. 85mm IMAGE LINK: https://flic.kr/p/tSyzeS CA checks 50mm IMAGE LINK: https://flic.kr/p/sXSTkw 85mm IMAGE LINK: https://flic.kr/p/tUU1SV 50mm crop IMAGE LINK: https://flic.kr/p/tUTW22 85mm crop IMAGE LINK: https://flic.kr/p/tCrGtH "We don't see things as they are, we see them as we are." -- Anais Nin

May 31, 2015 22:20 | #505 Well, the CA is par for the course, same as the MkII. Shouldn't expect much difference, since it is the same optical formula...Post processing can remove most of it, most of the time... Gerry

More info Post edited over 8 years ago by 05Xrunner. | Jun 01, 2015 18:42 | #508 just double checked to make sure its maybe not the body. tried same thing with my 85 1.8, 24-105, and 70-200 and taking multiple shots with them every shot was dead on focus. the 50 is the only one that is all over the place with accuracy. So it seems like it has the same inconsistent AF as the old MKII My gear
