I remember starting a thread in 2012 about what a year for photographic gear it would be.
It’s 2018 and this year’s Photokina show is shaping up to be the most exciting it’s been in years.

Already announced products:

Nikon Z system
Nikon 500mm f/5.6 PF

Canon RF system
Canon 400mm f/2.8
Canon 600mm f/4

Fujifilm XT-3

Sony 24mm f/1.4 GM

Tokina 50mm f/1.4 Opera


Leaked:

For FF DSLRs
Sigma 28mm f/1.4
Sigma 40mm f/1.4
Sigma 70-200mm f/2.8
Sigma 60-600mm

For mirrorless APS-C and m43
56mm f/1.4


Rumoured:

Panasonic FF mirrorless system

Sony A7S3
Sony 135mm f/1.8

Ricoh GR3

I’m sure there are many more items I’ve missed but it seems like there’s something for every brand/system buyer although the new products do tend to look a bit high end.
