Strange: Did Sigma design the Olympus 8mm f/1.8 PRO lens?

Egami spotted a new Sigma patented a new 8mm f/1.8 Fisheye lens design. This seems to be the same kind of design of the new Olympus 8mm f/1.8 Fisheye prime lens:

Marius: “Sharing this in case it’s of interest to your readers; I’m a Fuji shooter, but I recently reviewed the PEN-F and it…didn’t go the way I expected. https://mariusmasalar.me/olympus-pen-f-25e291eda979“

Olympus released their full Q2 financial reports. And the news aren’t good:
Sales down close to 30% YoY due to market contraction and impacts of Kumamoto earthquake
This comes as no surprise as Olympus did forecast this in Q1 after the Kumamoto earthquake:
Sales in line with forecasts announced in 1Q despite difficult operating environment thanks to strong sales of existing mainstay mirrorless camera models
Still Olympus revised upwards the forecast for Q3: They expect to +3% in sales and +1% in income compared to the previous forecast


In many occasions and even on their own website Panasonic promised to release a firmware update by February 2016 on four MFT lenses to enable DUAL-IS. The owners of that lens are still patiently waiting for Panasonic to keep that promise…
