This year’s Photokina 2018 show is already looking as one of the most significant in recent years, particularly for the mirrorless format. Not only has Panasonic surprised everyone by joining forces with Leica and Sigma on two new full-frame mirrorless models, but this has also been the first Photokina at which Canon and Nikon have debuted their own full-frame mirrorless systems. 

On top of that, Fujifilm has announced two new medium format models – including one with a 100MP sensor – and Sigma has announced that its Foveon system will be going full-frame too. Leica, Ricoh Imaging and Sony have all had additional new products to confirm too, but with no product announcements and its Micro Four Thirds partner Panasonic focused on in its new system, Olympus has been overshadowed by pretty much everyone else.
