I ran across these stretchy silicone bands at Amazon that fit the E-mount lens perfectly. I use them to seal the flange where lens attaches to cam body. They can be easily rolled on and off the neck of lens to fit in the small recess groove next to the orange ring at the body mount (face of cam).

They are relatively cheap IMO, and may function to help seal the flange where lens attaches to camera. However, the lenses fit so tight in the Sony body flange, I question if this ring seal will really help all that much for dust. You'll have to decide if it's worth it.

They come in a 3-pack each having 16 bands. Multi-colored bands are also available. When changing lenses, simply roll the round band back against lens shoulder. Each lens can have one remaining on the lens when not in use. I've used them and they fit snug. Also can be used to bundle or tie wires, cords, cables, etc.

Can't believe I didn't see this earlier! Just finished an Amazon order... which, living in Chile, isn't something you may want to do whenever you feel like. Well... added to a list, I'll get'em next time. Can't wait to have the orange ones on my Alpha :D

Warning: The orange silicone band color is NOT a perfect color match to Sony's anodized orange flange ring. :(

But they do roll on and off lens barrel/flange groove quite nicely. That part you'll like a lot.

Ivan, I wasn't trying to discourage you w mentioning the color. Rather you seemed excited about adding O-ring to your Alpha, and you mentioned the hassle ordering by being in Chile — I thought it prudent to warn you about color match. I didn't want to feel responsible for your possible disappointment if you were expecting a perfect color match.

Sony's anodized ring is a deeper metallic orange that is likely harder to match exactly. In first two pics, I rolled the O-ring off the groove for easier color comparison.

And I'm adding these attachments for other people as well:

Absolutely! Wouldn't have liked to have that surprise... I'm super OCD on that, so thanks for that.

Love the idea, I ordered the all black ones... more of a goth look for my Sony...
