sure will be different.... especially 24-105 vs 16-35... two off this lens will get the different even you set the same aperture and speed... mean different lens got different dept of field... did i answer you question and any pro can give advice?
Hi Guys,
I have a dumb question about Canon L lens.
Comparing the f2.8 lens vs. the f4 lens (both L lens), would performance be the same if I am taking landscape and I set to f11 using aperture priority? All else equal.
step down like F4 vs F2.8, the sharpness and detail most performance in good result with F4 lens...! it's correct sir?
But I guess, the real question is... Can you tell the difference yourself if you saw the pics side by side? I bet not.

So, reading all your replies... my understanding is the advantage (more light, faster shutter speed) only sets in when I have my aperture set between 2.8 to 4.
Anything above 4, the 2 lens should be equal meaning that my shutter speed can achieve same speed for the same light conditions.
Wrong.... i think you better read this: http://www.clubsnap.com/forums/showthread.php?t=309544
You need to take note that every aperture opens the hole bigger or smaller....
f2.8 vs f4 = bigger hole vs smaller hole
therefore, f2.8 can afford to have a faster exposure/ shutter speed. therefore chances of hand shake syndrome can be reduced.
Aperture number getting bigger = hole getting smaller. therefore even after the aperture f2.8 and f4, the aperture will also affect the amount of light getting into the camera....
Suggest you read the guide ba~
Hi, thank.. this is exactly what I was asking...
Under low light conditions... if I set aperture priority for both lens at f11, would the shutter speed on the f2.8 lens still be faster? or equal to the f4 lens?
My understanding from reading the guide is SAME SHUTTER SPEED cos already forced both to f11.
Is this not correct?

Would be the same.
The only difference is that the f2.8 one will give you a brighter picture thru the viewfinder....
