Fujifilm Full Frame Mirrorless 28-100mm f/2.8 and 28-110mm f/2.8 Patents Spotted
FujiAddict reported today that Venus Optics is coming with a new Laowa 15mm full-frame tilt-shift lens:
“I received a new tip from a source that Venus Optics LAOWA has a new full-frame 15mm tilt-shift lens coming that has been tested on a 44x33mm sensor without much vignetting. This lens is still in development so details may change, but on the GFX you can safely shift by 7-8mm diagonally and vertical shift by up to 11mm. Many in the GFX community have been eagerly awaiting a good shift lens so this will give them yet another option when it is formally announced.”
Maybe this is the Venus Optics Laowa 15mm f/4.5 W-Dreamer shift lens I reported a few months ago here and here:

Today Olympus officially agreed on the transfer of their Imaging Business to Japan Industrial Partners (JIP). The name of the new company will be “OM Digital Solutions Corporation” – this is pretty much the only new information provided. Similar to previous interviews and press releases, many questions remain unanswered and it’s still not even clear if the cameras sold by OM Digital Solutions will be under the Olympus brand.
Here is the full press release:
