70 - 200mm 4L vs 70 - 200mm 2.8L mkII

[Snoweagle]

I actually have 1 question, Lets say i use 70-200 F4 and 70-200 F2.8, both in same aperture, lets say F4, use same focal length lets say 200mm, taking same subject, will the F2.8 give me nicer bokeh than the F4? I cant really test it since i only have the F4 , i'm only sure that the F2.8 will be sharper at F4, but how about the DOF and bokeh?

DOF is definitely shallower as the number says it all. Bokeh wise honestly if u just look at the picture as a whole there wouldn't be much difference unless u really go and take note of all the details of the blurred background.

Hmm.... Im having the f2.8 mkii, are you using it as walkabout lens? For info, the mkii is about 1.5kg without body, twice as heavy as f4.

Did not have chance to compare IQ between the 2 but the focusing speed and sharpness on the mkii is excellent. By the way, I'm using 550D body.

70-200 is too tight as a walkabout lens on a 1.6x crop, but does very well in this respect on a full frame sensor.. at least in my opinion.

And yes, the 4L IS makes a far better lens for overseas trips, for its (much) lighter weight and more compact body.

But on the 200mm end on FF, is a tad short IMO.

aero93t, can you take a photo with both the 70-200 lenses at f4 and tell us if there is a difference in DOF and bokeh?

Sure. Took some photos with the 2 lenses, all taken handheld with a 5D II, with both the lenses at f4 apertures -

1) 70-200 f4L IS at 135mm:

2) 70-200 f2.8L IS II at 135mm:

3) 70-200 f4L IS at 200mm:

4) 70-200 f2.8L IS II at 200mm:

I feel that the f2.8 bokeh is smoother and less harsh

 

[Kenneth67C]

I think the difference is marginal at best, question is whether that difference is worth 2x the price of the f4?

 

[aero93t]

Actually i would have expected the DOF and the quality of the bokeh to be identical since both lenses were set to the same aperture..

 

[Aliva]

well, it seem that f2.8 is smoother.. any pple use f2.8 thinks it is worth it ... coz of the DOF .. or f4 will be better in turn of price and weight and yet can produce almost the DOF as f2.8

 

[engrmariano]

definitely yes for me... but i already ditched my 2.8L zooms to go all prime...

 

[Aliva]

prime is better?

 

[Snoweagle]

prime is better?

In terms of speed and aperture, it's indeed better.

the F2.8 IS II is pretty sharp even at F2.8,no need to stop down is good enough..
