I'm still in the pilot phase!!!
I just had a good think about what I shoot and the focal lengths I needed, and how many systems I needed. Then I sold off all the digital kit I didn't need, added one GFX lens and thats been it. I have bought a couple of cheap old MF lenses just to play with in the meantime but nothing like the dollars you Sony guys love to splurge
So my entire digital kit list (excluding the Sony ZV-1 which is purely for work)
GFX50S + GF30mm, GF45mm, GF63mm, GF100-200mm
X100F + Wide Angle Converter + Teleconverter
X100 - I'm keeping this cos its lovely!!
So single most of my shooting is in teh range 24-50mm (FF) my kit covers this.
Tthe only thing I have a bit of lust for is a GFX100 II, because this would give me much faster AF, an amazing EVF and IBIS, and I can use my Tilt-EVF adapter on it. but at £7K it can stay in the shop, knowing that in 12 months time a Fuji promotion combined with Black Friday will have it at a much more manageable price.
I also like the Leica Q2/Q3 but having used the GFX50S + GF45mm as my sole camera gear for a week in Malta, I 'think' I can give them a swerve.
But unlike some of you I don't shoot a wide variety of focal lengths, so I don't have to worry about telephoto lenses or super wide angle
