I think I am likely to give up both DSLR by mirrorless, probably some of the lenses too like the Sigma 50A.
The lists of lenses to replace…
16-35/2.8 - This will cost me a fortune to change as my Canon isn't worth a lot, it's the mk1.
24-70/2.8 - might not even bother because i seldom use this. Might get the Tamron 28-75 instead.
24L mk2/1.4 - Already have Sigma FE mount on order
100L/Macro - I can probably swap for Sony 90mm Macro like for like
135/2.0 - Sigma 135/1.8, by all accounts a better lens
20/1.4 - I could either sell and rebuy on FE or get the mount changed.
35L mk2/1.4 - sad to see it go but it's a lot of money to sit in a case, already have the Zeiss replacement
Will keep
45/2.8 TSE - manual lens, so make no difference
85L/1.2 - I can't bring myself to let this go just yet, until Canon make one on the RF mount
