Related Questions and Answers

Q: 1. Ryan, if you're out there, I would be very interested to know if Canon's 18Nov2019 firmware update solved your IS issues (which you posted a detailed review about on 11Sep2019)?

A: Update: the following issue has been addressed via a firmware update. Note that a 600mm III lens image stabilization problem was being reported by, initially, some 5D Mark IV and other camera users. Reportedly, this lens produced a ghost-like blur at longer shutter speeds when shooting through the viewfinder with IS enabled. Initial reports indicated that 1/250 or 1/200 and longer shutter speeds produced this effect and further reports specify that the blur disappeared at 1/250 and only longer shutter speeds are concerned (1/160 was reportedly the worst). Again, this issue has been addressed by firmware update v1.1.2.

Q: 2. Is their any reward on the 600 III that I just preordered , other than having a great lens?

Q: 4. I own version II of this lens and want to upgrade to version III. I also own both a 5D Mark IV and a 5R. I am concerned that version III image stabilization will not work well with either camera. Is there any update on this issue particularly with the Canon 5R?

A: Canon did release a firmware update for this lens that addresses known focusing issues with this lens.
