Well I have to keep the A mount stuff aka weddings and things no choice there. However I was thinking of giving the XS-1 to my son who is 10 next month, though I wonder if it's a bit "hefty" for his age (it's not a light camera)
The X10 isn't going anywhere it's a flawed gem but a gem, ditto film bodies I have plenty and they don't take up much space (have to finish off some Ilford in one film 7 body) F70 I used that quite a bit for casual shots and it's still competitive for a smaller sensor superzoom (IQ wise) I don't really need it though with the X10 around
The conclusion I've come to is the 18-135mm means I don't really need the XS-1 (Even though I like it, and it was a bargain and the 24mm is handy as is the mega range.) nor the F70. I'm finding I'm not using long tele that much and the XS-1 is a similar size/weight to the A57 or even A77 and 18-135mm...both bodies allow you to crop quite aggressively either in post or in camera with that lens.
I think we're probably spoilt in some ways the X300 was a reluctant acceptance as I've no interest in the old MF lenses, though I will throw a few rolls through it for those days I fancy a keep it simple 50mm outing.
I forgot I still have my IS-1000 Olympus which works 35-135mm I used that for years and the lens is very good indeed (the design is odd ball and it sucks batteries with powerzoom) When I got hold of a 28mm lens it was a revelation to me..though in some ways I think I must strip things down a bit here. I really only need 1 non SLR type camera.
Can't really justify throwing out the 35mm bodies I don't use much seems sentimentality rules to roost
