I have a Canon 7D and a 70-200 f/4 IS L, and lately (well, at least since around the start of the pandemic) I've been noticing that I can't shoot anything sharp with it for the life of me. But it seems like more than just being out of focus. In fact, images look more like something from a Holga or one of those toy cameras with deliberate irregularities.

This image is a good example of the issue.

Anyone seen anything similar, and have an idea as to the cause?

My 70-200 f/4 IS L suddenly developed a similar problem. I could not get a sharp image even when focusing manually. I sent it to Canon USA for repair and they fixed it for $200 (in 2013).

hi Dave, did you ask canon what the issue was--and what was their answer?

I was on a hike and using that lens and the problem started suddenly. I don't recall impacting the lens.

ok, pixseal, that explains it...your lens had decentering issue--it can happen to any lens! i had this lens and loved it, it is one of the best canon makes. i lost mine in a park but replaced it with a new canon 100400 II at the time and never looked back. i am getting the itch for a 70-200 f4.0 IS again, and i am very close to get a copy. it is a great small tele lens for travel, producing some high quality photos! good luck.

if you look at God real close and for very long, you'll find defects!!!
