hmm think i got mixed up
cuz usually i see that lenses state the they can go from e.g. 2.8-6.3.
but i suppose that the can go up to 22~~ or higher

Also to add on, sometimes you stop down to do stuff like.. Smooth out waves for that blurry smoothed out effect.To add one more point - normally beyond F/11 defraction starts to set in so don't close it down too much unless you really need the DOF badly.

No no no. What I'm thinking is that you see the 2.8 - 6.3 is the maximum aperture (or rather, smallest f-stop number) that the lens can go from a certain range.
i.e. when a lens is 70-300, f/2.8~6.3, it means that maximum aperture at 70mm will be 2.8, and at 300mm will be 6.3.
But anyways, f/8 and f/22 - f/22 will definitely give you a lot more DOF, but more often than not this is not discernible or evident if you're shooting landscapes - more evident when you're shooting stuff like macro.
ya lor...shoot spider sometime f32 also not enough
Macro lens is different. It is the design of macro lens you will lose the stop. At minimum distance (macro distance), the aperture will stop down (1 or 2 stop IIRC, depend on what macro lens) from aperture it can achieve in long distance.Tat brings me to a point... What is the minimum aperture that a lens is capable of?
I just tried my Tamron macro and it allows me to take it down to f64 when the lens aperture ring only shows up to f32. :think: :dunno:
