dof test by northy

dof test

no need to comment... just comparing dof from three different cameras to test the theory that sensor size impacts dof... i'd say the theory is confirmed...

I'd agree with your conclusion but then you also have to somehow factor in the difference in DOF with the difference in price etc.

Interesting exercise... the question now is what does one do with this knowledge?!

@vignouse not much really... I did it because someone started a thread w the question of whether it is possible to get good dof with a p&s... the guy at the camera store had. Warned me that dof on the micro 4/3 wasn't as good as with the cropped sensor, so I decided to see w hat the practical reality was...

@northy Fascinating subject - you use the phrase 'not as good' but I suspect many people would consider it better as those seeking a snap to record an event often prefer back-to-front sharpness in an image.

@vignouse haha! You are right about that... info believe he told me I would get better dof because more would be in focus... I, however, interpreted that the other way ;p

@northy @vignouse It most definitely does depend on the sensor size. In the same way that effective focal length does. f/1.8 on an APS-C sensor is close to an "equivalent" FF f/2.8. Another reason FF cameras (or even medium format) are the preferred professional portrait photographer's camera.

Very interesting exercise. Do you think the different lenses had an effect on this at all, creating another variable to the experiment?

@farmreporter hard to know... but I used high quality lenses on both the canon and em5 so I'm thinking not...

You are probably right - quality cameras really do make a difference!

Good to read the comments, the more I know and learn etc....

I never realized this. Fascinating.

I wondered about this myself and not having anything other than my micro 4/3 had no way of comparing. So thanks for that:)

Interesting - that explains a lot

That's actually quite a big difference - I'd have assumed the f2 would be shallower ...
