Replace my well used t3i.

I think I finally killed it. I think the dampness of many trips on the boat, plus 2 serious splashings, like a bucket of water, have finally cought up with me.

So here is my challange.
I am going to stay Canon.
I am going to stay dslr
And I am going to stay cropped sensor.

The choises, for me, boild down to a 80d, 90d and 7d mk11. Probibly used.

I have done my homework and any of the 3 should meet my needs ( mostly birds and sealife from an open boat)

My big question is about weather and dust resistance. How sealed up and robust are the 80d and 90d bodies?

Obviously none of these are intended as underwater cameras so serious drenchings are another matter but what about reasonable splashes and damp conditions like life on a boat?

Btw the 3ti is now resting in a container of dry rice. After a week in the container it is showing some recovery but I doubt it will ever fully recover It's just a matter of time before it moves across the Jordan to it's final resting place.

Thanks
Bill
