Before to move on to BIG rumors let’s clear the path by posting some minor news and rumors:

One:
Canon PowerShot SX70 HS Digital Camera has been announced yesterday and you can preorder it at BHphoto.

Two:
Sony registered a new compact camera named WX800 (via Nokishita)

Three:
The Fujifilm Instax Square SQ20 (read more at Fujirumors).

Ok, reayd to go now? Big rumors coming!

And so all cards are on the table now: ON September 25 Leica, Sigma and Panasonic will announce a new profound partnership. Together they will develop cameras and lenses based on the Leica SL mount.

Expect them to announce cameras and lenses that will likely out-wow what Canon and Nikon announced weeks ago. But will that be enough to get a meaningful market share in the FF mirrorless world? You tell me in the comment system…

First the bad news: Tomorrow Sony will NOT announce any new camera. And now the good news: Sony will announce a new 24mm f/1.4 GM and possibly a new 135mm GM lens too. The image on top shows the 24mm GM lens which looks quite compact in my eyes. Nice lens! Let’s hope Sony will not put a stupidly high price tag on it…

Fujirumors shared these accurate size comparisons with other medium format camera. The GFX50r will be announced next week and with a price tag of $4,500 be the cheapest and most compact medium format camera on the market.

Still the camera is much bigger than the X-E3:

Sigma 56mm f/1.4 DC APS-C E-mount lens

Sigma is going to make everyone happy by announcing a new set of lenses. The image on tops shows the Sigma 56mm f/1.4 which will be available for MFT and Sony E-mount users. Below you can find their new Full Frame lenses which I suspect will be made available for Sony FE too:

Sigma 28mm f/1.4

Sigma 40mm f/1.4

Sigma 70-200mm f/2.8

Sigma 60-600mm 4.5-6.3

Fujirumors shared these 100% accurate sketches of the new GFX-50R. Rumored specs beside the alreayd known 50 Megapixel sensor:

priced around $4,500
dual SD-card slot
no more cooling box
EVF only
2 axis tilt screen
first real life leaked image

This could be the first Medium Format for the masses! I know, $4,500 is still a lot of money, but only a couple of years ago you had to pay $10,000+ for these kind of cameras. And maybe next year the GFX-50R will get some discount and get closer to the $4,000 price…
