as the qns above, doesn't crop sensor capture less amount of light?
Aperture will still be f1.8. Due to crop sensor factor, focal length will multiply.
Light going through the lense might be lesser (depending on scenario) by 0.3 stop etc.
does that mean the bokeh effect of F1.8 in full frame is the same as cropped frame? I think the bokeh effect is larger in cropped frame because the effective bokeh that you are looking at is at a larger focal length due to the 1.6X factor.
It is still the same lens, how can the focal length change? Only FOV changes.

Bokeh effect as in?
Bokeh should be dependent on the lense no of blades.

Actual focal length DOES NOT multiply.
Assuming you have 2 cameras, one full frame and one with a cropped sensor that are both 10MP, have 2 exact same lenses on both cameras, taking the same photo from the exact same spot and settings will give you the same DOF.
erm, but when i use the online DOF calculator, at same focal length, aperture and subject distance, DX camera will have less DOF than FX camera.
anyone can explain? :think::think:

You can't compare FF and crop at the same subject distance as the FOV is already different.
If you compare using subject distance on the SAME FOV, you will get equal DOF
As others mention above, if picture taken at the same spot, there is no differet. However, to achieve the same framing, u need to stand closer to the subject with the full frame, which lead to shallower DOF.
