I am curious if anyone else has had issues with the RF 24-70 2.8 sucking lots of dust and debris into the lens.
I am a photojournalist who has been covering the recent large fires in Northern California and have had to send my RF 24-70 to Canon twice to be cleaned within a month due to getting tons of dust and ash inside it during the process of photographing the fires. I made the transition over to the R system this year, so all of the bodies (R5's and R6's) and lenses are less than a year old and still under warranty and these are the first large fires I have covered using the RF system.
I have been photographing fires for almost 30 years, most of it with Canon's EF zooms (16-35, 24-70, 70-200 and 100-400 of both the earlier and more recent versions of these lenses) and have never had any issues with crap getting inside the lenses while covering fires on a consistent basis.
I have also had no issues with dust/debris intrusion into the RF 15-35, 70-200 or 100-500 during fire coverage this year... only with the 24-70.
I am also not changes lenses when out in the fires which obviously could introduce foreign objects into the rear of the lens. I am also not doing anything extreme with the lens, dropping it into piles of ash, or anything like that. Just normal use in covering fires.
Canon has happily cleaned the lens twice but has not been forthcoming as to why this lens seems to have such poor sealing compared to my other RF zooms, nor have they shared what steps they have taken (if any) to fix whatever deficiency is causing this lens to start looking like a 24-70 snowglobe after a few days out at the fires.
I am just wondering if others have had dust intrusion issues with this lens or if I just have one that seems to be missing some part of the weather sealing that keeps dust out.
