I've been looking at camera bags and they all seem quite bulky to me. Seems they mostly cater for buly FF gear? So I was wondering if there was a small-ish bag that could be used to house three or four of the small primes (eg: 20mm, 45mm, 25mm). You could almost roll them up in a sponge cloth and be done with it One idea I had was to find a small toiletry bag and pad it out with some soft lining. But is there anything small and designed specifically for 3 or 4 tiny MFT primes?
