Well hello.
I'm a little late with an update. That's primarily because of lockdown and working from home and, well, life in general.
Okay, so I'm running the FP on v 2.0 firmware, which in the main is focused on the Cine side of things, with the exception of perhaps cinemagraphs and improved AF.
So, how have I found it? Got to admit, the absence of an integrated viewfinder is perhaps the most glaring omission (but I think this will be addressed if/when the Mk 2 is released). I don't have the LCD viewfinder and I won't be getting it, no matter how much its helps, which sounds a little petulant, but I'm a stills shooter in the main and I think I'd feel a little self conscious.
So, at the moment I'm left to composing via the LCD. Which I never had a problem with on the GR, yet on the FP, seems a little weird. The LCD is reasonably bright, but I have maxed-out the brightness of the display to combat the current bright light we are having. In really intense light, it is a struggle - although thankfully, living in the northwest of England, that won't be an issue very much.
I have always used single point AF and focused / recomposed in most cases, so I can't advise on how well multi point does or tracking. Considering the FP is contrast detect only, it fares no worse than other cameras I've used with the same system. It's quite snappy. I've learned not to use the smallest focus area for critical focus, as the medium size appears to have greater chance of locking focus on areas of different contrast. The smallest focus area should be reserved for less time critical work.
Under normal circumstances, I have always been a people shooter. I'm happy to report that the face/ eye detect does the job just fine - and another reason not to attempt to use the smallest autofocus area for critical focus - let the tech work its voodoo (I realise this is hypocritical as I don't use multi point lol). I haven't tried Pre AF yet. Probably won't bother, either.
The FP seems to overexpose a little, whereas I like to perhaps underexpose, so it's normally a case of tweaking the EV comp by around 0.3. But it is a little inconsistent (or my eye is?).
The RAW files are nice. They don't require much work on the whole. They remind me very much of RAWs from the Sony RX1.
The 45 2.8 is also a really nice, capable lens, if a little too long (focal length wise) for me. Close focus is something silly like 20cm, so you can get fairly intimate with subjects and, whilst f/2.8 isn't considered to be overly bright/fast, the bokeh is fairly pronounced wide open, so would definitely lend itself well to portraits. It's a nicely built lens too - hope Sigma do more like this (preferably between 28mm-35mm, where I'm happiest).
There are many superfluous options that seem a little like overkill to an amateur like me. I use digital cameras very much like I do film cameras. I do kinda think that if Sigma put a little more effort into their baked in presets though (as I know that film simulations and the like are currently in vogue) then they may broaden their appeal a little more.
My intention with the FP was for it to be there to support my Foveon bodies when their operational limitations were exceeded. I'm a big fan of Sigma, but not so much that I can't see issues.
You're probably expecting example images? I'm afraid I'm a little bit shy with these things, until such time I feel I have been able to photograph something that suits my style of shooting. So, no coffee or cat shots from me, I'm afraid.
Lockdown is, rightly or wrongly, easing in the UK now, so I'm confident I'll perhaps have something to share soon. However, I'll leave the floor open for questions, if anyone has any...
