Ngl, I feel your pain so much on the dust issue. It drives me absolutely insane how fragile that sensor feels when it's just wide open like that. Even though I'm super happy with the results I get, that constant fear of a speck ruining a session is always in the back of my mind. The technical side of why it happens is basically a perfect storm:

• Short flange distance means the sensor is physically closer to the elements.
• Lack of a mirror box means there's no physical baffle to catch debris.
• The electronic shutter curtain is incredibly delicate if you have that set to close. I've been using the Canon RF 50mm f/1.8 STM lately because it's so cheap and honestly performs way above its weight class, but I still hate that feeling of exposure. It's like you save money on the glass but then spend all that mental energy worrying about a clean sensor... anyway, glad you're enjoying the jump to RF so far!

Like someone mentioned, that sensor exposure is no joke. I remember when I first made the jump to mirrorless, I treated the body like my old tank of a DSLR. Ended up with a massive spec of dust that looked like a bird in every single shot of a wedding ceremony. Technical specs show the clearance between the mount and the sensor is way tighter now, which makes the airflow patterns during a lens swap pull in more debris than youd expect. Heres a few things I learned to avoid:

• touching the gold pins on the mount since skin oils can actually increase resistance and cause lens communication errors
• leaving the body open for more than a couple seconds even if youre pointing it down
• blowing into the chamber with your mouth because of the moisture risk Honestly, its mostly about being methodical. I usually keep the rear cap of the new lens loosened and ready to go before I even take the current lens off the body. Keeps the exposure time to a minimum.

> Thanks! Glad you finally settled on something. I have been really happy with the RF system since switching over, no complaints at all about the image quality. One thing you gotta watch out for tho is the sensor exposure. Since there is no mirror in the way, its super easy to get dust on the glass when you are swapping lenses in the field. Always point the body down. Also, stay away from those dirt cheap non-electronic mount adapters you see on auction sites. They might save a few bucks but losing the autofocus and lens data makes the whole experience pretty frustrating, honestly. Not worth the headache when you want things to just work.
