Perhaps a specific scenario might help focus the discussion .

I went to a fundraiser on Tuesday night for a local charity.... they had several trips for auction that where on my bucklet list so I thought I would bid on a couple of perhaps get lucky..... well..... 1 trip to Iceland and 1 to Africa later.....

I have 3 years to take the trips, and the wish list is now what lenses should I take - and even what camera body - I have a R5, but for Africa would a rental of a R1 or R3 be more appropriate?

What lenses would you take on either or both?

Thanks for the guidance.
