Olympus 12-40 easily beats the Canon 17-55 at f/2.8 (but not when stopped down).

with FF and 43 lenses then you know that you always need to stop down the FF lenses but generally don't need to do that on 43. I guess if you don't then you don't.

Exactly the otherway around.

Nikon 50 F1.8G and 85 F1.8G are very sharp wide opening, when used with a 24mp FF sensor. you can say it is bleeding sharp by m43 standard.

You mean just as bleeding sharp as the following figures suggest (line pairs per image height at MTF-50, center/average, based on unsharpened output from RAW files)?

Nikkor 50/1.4G on D3X (24 MP)

1.4 560/500

2.0 690/620

2.8 830/750

4.0 900/830

Panasonic 20/1.7 on E-M5 (16 MP)

1.7 870/835

2.8 1050/875

4.0 1075/880



On the other hand m43 with 25 / 0.95 and 42.5/ 0.95 are very soft wideopen by FF standard.

Digital lenses just seem to be of higher quality. It's a half thing. For the same quality the digital lenses are half the size, half the weight, and half the cost. LOL

Exactly the otherway around again.

M43 lenses of the same image quality - which has to mean equivalent aperture - are often heavier, larger and significantly more expensive than FF lenses. again, compare m43 25 / 0.95 vs Nikon 50 F1.8G.

So which FF Nikkors would you recommend as equivalent to the lenses I am currently using?
