I have noted previously my lack of finance, or unwillingness to borrow, when I was moving from film to a good digital which spared me from exchanging my SLR for a DSLR but to getting a DSLR Like. I found that Nikon bridge camera quite tremendous to use but they didn't upgrade it the way I thought I wanted [ going for tight framing ] so I switched to Panasonic which over three models kept me happy except for the obvious problem of noise and small sensors. So in going to MFT I got a larger sensor without the weight and expense of doing it with a DSLR body. I had a basic D60 whose only purpose was to use extension tubes/bellows from film days and was given away to a 'good cause' when I got MFT.
The bridge goes to 430mm while the MFT is 280, but my original Nikon also is 280 and serves me well after a decade and I can add either legacy or current longer lenses and of course extension tubes/bellows with MFT.
My rig[s] suit me because I am less interested in ultimate IQ which I consider a fools errand but tools to capture what I see at a reasonable IQ standard. So MFT is both lighter and cheaper than DSLR and more than adequate and has opened up high ISO ventures which the bridge was incapable of.
EDIT As I dredge this photo out of my files I see it is not up to my 'reasonable standards' Sorry!
