Hi chings,

I wanna to know for 70-200 IS F/4 L, at 200m and F=4, is it possible to create 淺景深 - just like I am using my 50.8 at F=2.8?

Similarly, for 24-105 IS F/4 L, at 105mm and F=4, is it possible to create 淺景深?

I am considering these lenses vs 24-70 F/2.8 L and 70-200 F/2.8 IS L.


THANKS

anyone here can help?

I know f2.8 can make 淺景深 but not f4.
but for tele, it may be different (I mean at tele side). I never use a tele before, so need to seek someone's opinion here.

THANKS

長鏡景深同大光圈景深好似好唔同....
其實有時攞的角度OK都出到好靚...
最緊係睇下你想影咩多.,,,
如果只講景深唔計其他野.,.,.
18-55都做到....

Short focus distance, large aperture and long focal length are the 3 key elements of generating "Shallower Depth of Field"
