Is a Micro 4/3 a silly idea

[Mr niall]

Hello all

I'm struggling. I own a Lumix G2. It is indeed a very elderly camera (bought new for £700 (ouch!) in 2009). Its a Micro 4/3 format and it is definitely my favourite camera ever ever.

But it needs upgrading. I have owned a Nikon D3400 and an EOS 1300d, which were nice but a bit too big for everyday use. I also had a EOS M10 which was amazing but with no way to attach an intervalometer and a max 30 sec exposure wasn't really much use for astronomy. They all got moved on.

I'm really considering getting a Lumix GX800 as it would be a considerable step up from my old G2, and it could use my G2 lens too. But would it be a silly idea if my biggest reason for upgrading would be to use it for imaging? I'm not a very good imager at the best of times (only widefield playing up to about 150mm) but would the move to a micro 3/4 be tantamount to shooting myself in the foot? I've had a look at sensor sizes and it is a fair bit smaller than an APS-C. But then again I've never really heard a huge amount of argument about APS-C being pointless compared to Full Frame...

I don't know... has anyone had much success with a 4/3 (I know the ASI1600 is 4/3 but that isn't really a fair comparison!)

Thanks all.
