| p.1 #1 · Canon 600mm II problems |
just took delivery of a brand new Canon 600mm II on Thursday. Since i didn't have time to try out this beauty that day, I decided to see how it was on Friday. Well, it seems that i'm having focusing problems with it. I mounted the lens to my tripod and gimbel head and then mounted my 1Dx to it. I focused on an object approx 30' away and took a few shots. They were all soft. I checked the settings on the camera and took more shots of various other objects ranging from 15' - 40' away and had the same problem. I also noticed that when looking threw the view finder i could see that although the camera acheived focus, they were definately out of focus. I started shooting at iso 400 f4 and about 1/320 sec. with the is turned on. After seeing the results, I cranked up the iso to 1600 and f/4. at these settings the shutter speed was between 1\4000sec to 1\6000 sec. I did this to eliminate possibility of camera shake. the photos were still extreamly soft. Then i turned the IS off to eliminate the possibility that the IS wasn't catching up to my shooting and still the same results. Today, i'm going to try it out again with my 1DsMIII and check the results. It they are good today with that camera, i'm going to assume that Canon didn't apply the new firmware update to this lens. If anyone else has experienced these problems with this lens, please let me know what the outcome was. I know i can send it to Canon for repair, but i would really not want to take this course of action since i've had a few absolut horror stories dealing with them in the past.
