Most of the day spent trying out various different lenses on the K1 ii. I don't know if its me, the camera or the camera lens combination, but many of the lenses do not behave in the same way on FF as on crop (not talking about FOV or DofF). Some are better, some worse and some about the same.
Better (so far):-
M 20mm f4 - very meh! on crop but pretty decent on FF.
Voigtlander SL II 40mm f2.0
About the same:-
K 28mm f3.5 - really pleased about this, as it will be part of my landscape kit
HD FA 35mm f2.0
M 100 f4 Macro
K 55mm f1.8
HD DA 70mm f2.4 Ltd
M 85mm f2.0 - finally I have use for it! Only bought it a few years ago as it was way under priced.
Worse:-
K 35mm f2.0
K 50mm f4 Macro - surprised about this. It's easily my favourite 50mm on APSC, but on FF my copy seems to exhibit a lot of glow.
Some pictures.....
K 55mm f1.8
Voigtlander SLII 40mm f2.0
M 100mm f4
And two at 70mm. HD DA 70mm f2.4 and Tamron SPII 70-210 f3.5/4, ancient two touch zoom (but I love it)
