I was referring to exposure rather than total light gathered.FF sensor gathers 4x more light than a m43 sensor. So m43 is still under by 1 stop disadvantage i.e. it'll still gather one stop less light.
This basically reflected in FF having about 2 stops more ISO advantage over m43. m43 makes up for one stop from a f2.8 but still down a stop
I agree, it’s only really useful to know at high iso and/or if you really need the DR.I just think that the view often expressed on forums that FF captures x times the light and has x stops more advantage has always seemed at odds with what ordinary non pixel peeping obsessives see when they look at pictures and needs qualifying and explaining.
Yep, and I would add that lenses (obviously) and the way you process make a huge difference too. I’ve recently been playing around in LR with my Olly images and have developed a preset which (imo) has transformed my images.A ps to that.
When looking at FF v MFT or APS-C you have to remember that with the smaller formats you're likely to be using a wider lens...
FF = 50mm f1.8 = aperture of 50/1.8= 27.7mm.
MFT = 25mm 1.8 = aperture of 25/1.8= 13.8.
Theory is nice but take a FF and MFT out and shoot them side by side applying the crop factor (shoot FF at f8, MFT at f4) and few people will be able to tell the difference.
I spent a lot of time and money on this comparing FF, APS-C and MFT and concluded that I'd mostly wasted my time
Whilst I’ve always been happy with my Olly images they didn’t have the clarity and punch of my D750 images, but I’ve recently discovered that Olly images need quite a contrast boost in LR (I use the tone curve for this). The trouble is that when you first apply them to the RAW it’s quite an extreme change so I’ve thought I was over baking them in the past, but when I compare them with my shots from the D750 they’re not. I’m therefore assuming the Olly RAW files lack quite a lot of contrast by default. I’ve also noticed that often the don’t spread over the full luminance scale of the histogram and by adding the high contrast hike they do then reach the blackest blacks and whitest whites (although of course this doesn’t always need to be the case).
Anyway, my point is that at normal viewing sizes I can struggle to tell the difference between my Olly and D750 now (scene, lens and DOF dependant )
