Fujifilm UK kindly lent me the new 30mm tilt/shift to have a go with - unfortunately they did want it back...
I'll happily say that it's by far and away the best quality wide tilt/shift lens I've yet tested...
I was able to test it on my own GFX100S and for a short while on a GFX100II [spoiler alert - no significant differences ;-) ]
I've a longish written review [over 5k words] at:
https://www.northlight-images.co.uk/fuji-30mm-ts-review/This includes two videos:
The first is about the lens itself [~19 mins]
https://youtu.be/YqM5CYpIeoYThe 2nd is about using it and its quality [~34mins]
https://youtu.be/ODRtFF_9ciAI'm now hoping to get the 110mm to test some time.
Definitely left me wondering what improvements both Canon and Nikon could manage when they finally bring out T/S lenses for RF and Z mounts.
Hope it's of some interest.
PS Now waiting for the 110mm TS lens to have a look at
