something like 70-300mm kind? is it impt to have good aperture for those lense..
for example: AF-S VR 70-300mm f/4.5-5.6G IF-ED but its only f/4.5-5.6G...

summary = if not shooting fast moving object, no need big aperture for zoom lense?
think i got it THANKS!

I initially oso tot about the bokeh effect thingy...
but after i read this remark, i am confused...
then does it have to do with these remark "a faster lens'll allow you to capture fast subjects in dim condition"
need enlighten...
A faster lens means larger aperture.
Larger aperture means more light will get in.
More light get in means your shutter speed will be faster.
Faster shutter speed means fast subjects can be captured without motion blur.
If your subject is not moving, you don't need such a large aperture.
But, still depends on the available light.
If it's too dark, you may still get blurred images because of camera shake.
Why? Because less light means slower shutter speed.
Slow shutter speed means your camera shake is more visible.
It's all about lighting. If there is enough light, you don't need to use a fast lens to shoot a fast moving object.does it has the same meaning as this remark "summary = if not shooting fast moving object, no need big aperture for zoom lense?" :dunno:
Does one define faster lens by looking at the f3.5 ~ 6.3 (smaller numeric the faster it is?)
Thanks
Assuming the object is a walking person from a distance. Weighing both lenses does the higher range(18-270mm) has an advantage over the shorter range eventhough the f. is lesser?
