Curiously I have reversed or perhaps re-reversed my habits for a 'carry-round' camera.
Twenty years ago, the carry-round was a neat little Olympus XA2 35mm-Film compact, to a bag full of OM SLR's.
I had toyed with going 'Auto-Focus' in the mid 90's, then again in Y2K with a healthy redundancy package, co-incident with infant Digital opening up options, and I shunned both in favour of a dedicated film scanner... and a bulk reel of slide film.
Three years later, when consumer compacts, which evolved far more rapidly than 'serious' digital cameras, dropped under £200, I bought one... 1.3 MPix, through-the-lens composition like an SLR, it was amazing! And used batteries faster than my notorious OM4! Making it also more expensive per shot than film! so 'not quite there yet' was the conclusion. It sort of became the carry-round, though the XA2 would often be close by for when the batteries went!
Three years after that, another, Kodak, compact, with 7.1Mpix, a 3x zoom and a long lasting, rechargeable battery, proved a bit more 'viable', and became the carry-round, and with TTL composition, and choice of 100, 200 or 400ASA, sort of challenged the SLR for a lot of situations, and saw them 'retired', as 'convenience' won out more often over anything else.
Three years ago, when the Kodak(s) had were finally deaded by kids.. and I needed a new camera, I went shopping and with entry level DSLR's having caught up and dropped into the £300 price bracket, the dilemma between a consumer compact, mirror-less or DSLR was 'eased' by mirror-less being bludy expensive for what they offer, and limited in the support their systems get. Consumer compacts? Choice has become dire, with camera-phones cutting the sector in half, leaving them either utra cheap 'toy' cameras, or much more expensive neither fish-nor foul almost 'bridge' or almost mirror-less cameras. Bang-for-Buck, entry level DSLR just chose itself!
AND begged the old gadget bag off the top of the wardrobe to lug it around..... or be left at home....AND... the 'old' 35mm film compact is back in my pocket more often than not!!! Reversing the habit of film SLR for 'serious', Digi-Compact for carry-round convenience.
Curious about turn that. Film was supposed to be the 'faff', Digital the 'convenience'! Has digital disappeared so far up it's own aperture, its now more faff than film?
It does bear some thought! And with so many spending so much time pontificating about white-balance, deliberating over 'RAW' and spending longer in 'Light-Room' than I ever did in the Dark-Room, analysis of the notion would certainly support the idea a long way!
Which begs some thought.. because that XA2 compact with it's fixed 35mm 'wide angle' lens was my only camera until 1989, and much travelled, much used it's delivered a heck of a lot of fantastic photo's over the years.. in years past we made-do without huge zoom ranges, even in the SLR world, all you might have was three 'primes' the standard 50, a 'wide' 35 or 28, and a tele, 90 or 135. Which begs a further thought, how much 'technology' do we really need? How much s actually 'useful'?
More thought, the other day, I was trying to squeeze my new lens into the 'old' camera bag. Err.. "WHY wont this fit!" was the quibble point, followed by "I USED to have two OM' with winders, and short zooms, on them in here, a long zoom, a tele-converter, 50 and a fish-eye, big 283 flash, small 'fill-in' flash; 16 spare AA's and a charger! And a dozen rolls of film or more, AND have space for a changing bag and a packet of wet-wipes! WHY when this 'electric picture maker' is supposed to be 'small', is just ONE camera body, FILLING the same bag, and I don't have room for a third lens?" Reminds me of an old adage; "Work expands to fill the time available; Clutter expands to fill the space available"
Stripped of it's winder, I was fiddling with the old OM10, and reminiscing, and it struck me, how way-back-when, rather than lug a whole back of 'kit' to the top of a hill, I'd leave it all in the car, and just slip that body on one pocket of my coat, and the lens in the other... it was always a 'compact' 35mm SLR, and side by side with my D3200, applauded by many for being so 'compact' as DSLR's go... made me wonder HOW they ever got SO big! It was interesting, picking up the 'little' super-zoom bridge I got as a 'carry-round' (to see where my daughter had hidden my spare SD Card!) and picking the OM10 up off the desk to make space for them both, having both in my hand at the same time, begging comparison not in the favour of the electric picture makers!
This probably doesn't help you answer your question. May yet beg suggestion I am advocating 'film', to which there could be some masochistic merit, But, I think, the conclusion it suggests is... there ISN'T an answer. It's all about compromise, and you just cant have your cake and eat it.
An 'everything in your pocket' compact will be compact, but the compromise is it will either not be very cheap or not be very wonderful, or a bit of both. A versatile SLR, will always offer 'more', but it wont fit in your pocket, and still not be all that cheap. In between? Bridge and mirror-less, lots of swings and round-abouts nudging the compromises, one way or t'other, usually upping the cost for little or no gain in compact-ness. You pays your money and takes your chances, and find what works for you the hard way....
But, while you have your pay-pal details to hand..... ;-) you might like to check out old high end 35mm film compacts on e-bay! You can pick up super-compact Olympus XA's, or Minox or Contax 35mm 'folders' for stupidly little money these days, and they make a great 'carry-round' besides a DSLR! LoL.
