Not really. Depends on lens quality as well. FF lens can be cheaper than m43 cause it doesn't need to be sharper due to bigger pixel on FF if both have same mpixel. M43 lens can be more expensive cause the sharpness has to be very good on a smaller sensor with higher megapixel density.

Also u cannot compare f2.8 FF lens to f2.8 m43 lens. On equivalent bokehness, the f2.8 will look like f5.6 on FF. Yes, there will be less light but since it has much bigger sensor, it also collect more light than m43 so really it balance out.

Yes bokeh and higher sensitive sensor are advantages for FF sensor, but my concern still shutter speed.
Not sure if got article to support or not, but in theory higher ISO will lower dynamic range ? Thus large aperture ( thus higher shutter speed and/or lower ISO ) gave good dynamic range ?

Ya but f2.8 lens mostly are more expensive on larger sensor system as size grow.

I keep dream but didnt upgrade to A7III, due to around-RM10K price tag of f2.8 GM lens  cry.gif

not only that most FF and APS-C lenses cannot match m43 sharpness wide open.

Not larger aperture, but amount of light. Short answer yes, lower f stop means more light (approximate but not actual measurement) so more light data collected so higher dynamic. ISO signal only boost the signal collected on the sensor just like how u move the exposure up in lightroom (except it boost exposure before being processed incamera).

But again it also depends on sensor tech in how efficient it can collect light data. Sony and nikon boast impressive sensor that have very high dynamic range on their FF even with very low light. Even Panasonic m43 sometime ago boast high dynamic range using new organic sensor.....but never heard from again.

U can collect more light aka more dynamic range if u use longer shutter speed. But if u want freeze subject, no way around physics but with bigger sensor and larger aperture and maybe one day impressive sensor.

I would ask back one question: if you intended to stick to only this setup, or will probably upgrade lens in future.
The 12-35 f2.8 are sharp lens, while 18-105 f4 are no where near. If will upgrade better lens in future, then can consider A6xxx or even jump to A7III which are really good body.
But f2.8 lens on m43 still give you f2.8 exposure, which helps low light with higher shutter speed.
For lazy zoom lens people like me, below are tempting  drool.gif
But the size ( next to panaleica 12 60 ), and likely the price will be big issue  sad.gif

a7iii is tempting for me too.
but FF size always holding me back.
thank goodness for that.

Don't go Fool Frame tongue.gif tongue.gif , you will regret it. I just sold my 45mm f1.8 lens a few days ago to a chap who just joined the m43 party. He told me he used to own a D7000 and is switching over to m43 due size. Hence he bought his first prime from me. I was tempted on and off to go FF (GAS lar), but whenever I look at the total system size, I lose motivation to take them out to shoot.

Ooooo yes, the Pana 10-25mm f1.7 is super tempting. I am starting to conserve bullets for that lens already, for once I want to try to own a pro lens like incubus_skj taikor. He probably has a money tree growing somewhere which he is not sharing with us. tongue.gif

The 10-25mm would really be the perfect lens for me were it not for the size. A bit too long at 13cm for me, had it been like 10cm, would be great. I also dread the weight. Really wish Oly would come up with a smaller 10-25 f2.

Generally m43 are significantly cheaper when compared to FF. Only in select cases are FF cheaper.

Also, for exposure, f2.8 is f2.8. We can talk about noise at same ISO, but I don't see any FF camera that actually offer 2 stops less noise at same ISO, although that's the theoretical difference. So to me, FF is not really 2 stops lesser noise. More like 1-1.5 stop if anything.
