My em1X arrived the sme day as the announcement. I'm keeping it, because I like a grip fpr verticals, especially with long lenses, among many other reasons. The original idea was to get the new long zooms, so I REALLY hope they still get released. I have the P/L 100-400, and it's OK, but I'm not in love with it and want to keep OLY lenses on OLY bodies. Also have the 300/4, and it's a great lens.
I also have a Z7, and among others the 500/5.6. Nice combo, but I prefer zoomz, and m4/3. Still, considering the news, it's nice to have options.
How do you like the 500 with the Z7? That is probably where I am heading in 3ish years if Olympus goes away. Right now the Z series and the 500/5.6 are the only combo of camera and lens that meets my requirements for weather sealing and weight/size. But I am honestly holding out hope that Olympus or whatever they name it continues.
