Well I managed to pick up my Sigma 85mm f1.4 tonight as the drop off point doesn't close til 10pm. First the good news, condition is so much better than I thought. It almost looks new, and it comes with all the caps, hoods and case. Now the bad news, it front focusses like a bugger, and AF doesn't work in liveview. With regards to the front focussing, AF fine tune makes little to no difference, something I've had with Sigmas and my D750 in the past. However, if I change the AF fine tune default setting (rather than saved value) +3 sorts it out. Default AF fine tune seems to make far more difference than "saved AF fine tune" as normally with this amount of front focussing would've expected +16 to +18.
So the questions are, why do we have two different types of AF fine tune, and will me changing the default effect all my other lenses. The fact it says default would suggest it'd affect all lenses, BUT reading the manual it says that it uses the default if no saved value for that lens is set, suggesting that it uses the "saved AF tune" setting first, if it doesn't have one then it'll use the default. As all my other lenses have some AF fine tune stored then I would assume that the default setting won't therefore affect these. Can anyone shed some light on it?
Next questions are,
is it normal for it not to work with liveview? Would others accept this lens with the AF tune behaviour. My camera does cause front focus on most of my lenses, with the 50mm f1.8 and 70-200mm being the worst at +18 and +16 respectively, but then I do have a couple that are +1 and +2.
Normally I wouldn't accept a lens like this, but if I can 'fudge it' to work (ie use default fine tune rather than saved fine tune) then it's an absolute steal, £380 for an almost mint Sigma 85mm f1.4 with 6M warranty.
