It’s rumored that in late 2023 OM Digital will announced those two new zooms:
- 50-200mm f/2.8 PRO
- 50-250mm f/4.0
Both are compatible with the MC-14 and MC-20 teleconverters and both are IP sealed. But I am not sure about the IS feature. For now it looks like the 50-200mm has in lens stabilziation while the 50-250mm might NOT have it.
