Olympus with 5 axis - advantages over bigger sensor or not?
I'm thinking of getting a Micro 4/3 in the future because of its small size and potential for great IQ (high res mode is amazing for object photography!). Plus the Olympus Pen F is absolutely gorgeous.
My question is: with Olympus' 5 axis stabilizer, which claim to be able to add up to 5-stop to your shutter speed, handheld without shake, how does it compare to a bigger sensor without stabilizer if the subject is people? For low light and social event situation.
Compared to say a fullframe (easier for math) with a 50mm F0.95 VS Olympus Pen F with a 25mm F0.95. ISO on fullframe is about 2 stops better than MFT since it's 4 times the surface and that F-stop is twice bigger, so that's another stop. So in theory, fullframe has 3 stops advantage over MFT.
In this case, if I shoot at 1/50 of a sec on the fullframe, it'll be around 1/6 of a sec on the MFT to be equal in IQ, which is doable by what Olympus claims (up to 5 stop). It's all good and fine, but how high is the pourcentage of having blurry shots because the subject moved?
Does anyone has experiences with that situation? Like using a Olympus with 5 axis at an event shooting with really slow shutter speed. How much is your rate of sharp photos?
