CF Express A is hardly established. Currently, there are no cheap CFExpress B cards, which deters me from buying an R5. Sure, current CFExpress cards have better performance, but that doesn't matter if I'm shooting portraits, panoramas, or time lapses.SD Express has 0% market share. And SD is an obsolete format. Why replace SD with SD Express when we already have CF Express A&B established in a much more sturdy forms. You will be buying £250 SD Express cards or £250 CF Express cards, why let a format that should have ran its course years ago continue? Especially when consumer cameras are a dying breed themselves.
