I have dual card slots so not an issue. But even then if it’s important photos I’ll take both cards out and replace them with 2 different ones half way through. So at least then I’ve got something to fall back on if somehow had 3 failures

My 28-200! It’s my all in one travel lens. Sure it’s only f2.8-5.6, but it’s just a great range.

Followed by my 200-600mm, it’s basically permanently set to 600mm!
