I don’t know if you had a chance to look at the pictures I put up, but the difference in image quality is very slight between the different combinations. If the lens mount is my problem, what would you recommend changing or replacing? Should I buy a new camera…Read more

I cannot tell too much from them. All of the pictures were taken from a tripod with IS off. The pictures named whatever 100mm were…Read more

One thing that I though of, my lens no longer fits snugly to my camera body, it used to, but now I can turn the lens on the camera some even when it is locked in. I did try the suggestion of switching camera/lens combos to try to pin point the problem.…Read more

Do any of you have a list of the Canon bodies that allow for micro-adjustments?

Usually I shoot Al Servo.

I do understand that my lens was created a long time ago, but I have only had it for a year and a half. Even though it is old, it seems like Canon would have made a better product than that. The 7D Mk II is sort of expensive, but not more than I am willing to…Read more

As for the picture I posted, that is perhaps in focus, but not crisp. The glass in the L lens is or was great, I could see every detail in feathers. I will post a few good pictures so you can compare. Here is the google…Read more

I have been shooting with the same camera body, I also took the photos in plenty of light. It is odd, sometimes I will get consistently out of focus pictures, and then randomly, a fantastic shot.

This picture I took at 400mm, from a tripod with the IS off, it was on a bright day so my…Read more

I own a Canon 100-400mm IS L first generation lens. I have had it for about a year and a half. I took a trip last weekend and took lots of pictures on the way, I was very disappointed when I looked at them on my computer and discovered that nearly all were blurry. Rather than motion blur, these seem to always be just outside the plane…Read more
