If so, I'd be very interested to hear from you with your experiences. The 75 has been the only reason I still cling to my m43 gear (it was stuck to my E-P5 before some teenager known to me broke it). Today, in the camera shop, I attached the 90 on to my X-E3. Didn't use it, just wanted to know how it felt in the hand in comparison to the E-P5/75, which I've always found astounding on a size/ performance ratio. And it didn't feel as big as I'd feared - got me thinking this really could be the one that replaces the 75. So I thought I'd aim this question at anyone who's gone through this process, for only you will know this weird feeling of actually bumping the 75, something I never thought I'd consider.
