Zhong Yi announced the new B4 to M4/3 2X extender:

UHD 4K + is a mount conversion extender adapter for mounting a 2 / 3-inch B4 mount lens developed by Zhong Yi Optics on a Micro Four Thirds standard camcorder. Equipped with a high-performance optical lens that doubles the focal length, the lens configuration is 8 elements in 5 groups, and by adopting a lens design optimized for the Micro Four Thirds image sensor, it supports up to 4K resolution (* used) If the B4 lens to be used is compatible with 4K).
The lens barrel is made of aluminum alloy, and the mount on the camera side is made of highly durable stainless steel used for cinema lenses. With a tripod mount that can be attached to and detached from an Arca-Swiss compatible standard tripod or pan head. (* Some are not supported.)

I just got this:

Olympus staff made redundant in UK today, some already gone in France and more to come across Europe in coming weeks!
Around 2/3 of workforce lost their roles in UK today.
Nothing published, but heard from Olympus employee whose last day was today!

Don’t know if this is a consequence of BREXT or also of the JIP agreement…

Robin Wong:

I have been receiving quite a lot of questions lately about whether to buy an Olympus camera or not, following the announcement of Olympus being sold to JIP, and exiting the camera business. I share your frustration, but taking a look deeper I think there is very little to be concerned about. Olympus is still operating as usual until the end of the year, and as JIP takes over, the global business will continue on, with full consumer and product support, that much I know. JIP and Olympus have made several announcements, and we know that the brand Olympus will be maintained, and the recently announced updated lens roadmap will also be fulfilled. Of course, I cannot speak for you, but the reason I bought and use Olympus OM-D system extensively was because it works for me and my photography, and that is not going to change. I can’t predict the future, no one can, but more news will come to light in the beginning of October when the agreement from both parties are firmed up.
