I just weighed mine. 1.3kg and then thought hang on there is a rather compact small umbrella in it. 150g. That makes it very similar to an OM1 with the 12-100 F4 on it.
I use a Troop shoulder bag as it's waterproof, Heavy canvas outer so gets heavier if wet.
I've no interest in bags that need a rain cover. Main reason I bought the Troop. Any suggestions where there is a range of sizes?
1.3kg is ~2.9lbs
I have been known to take photo's in the rain so easy access is important.
