macro newbie qns

[F34r]

im super newbie to macro.. if my qns has offended any macro pros here please forgive me

given that there're 2 lens of equal focal length and maximum aprature but one is macro and another is not. what are the differences, pros/cons ?

i also noticed that most macro shots uses a high f value and still able to achieve that nice bokeh.. why is a higher f value used compared to non macro lens?

thanks!

The view is the same, except that a macro can keep focusing down to a small distance, and that's when you get a higher magnification. A non-macro may only focus to a longer minimum distance, so the largest subject size is not so big.

Not really. The bokeh is also dependent on the focal distance, the closer the focus point, the less the depth of field. When people use high f-values, they are actually trying to get maximum depth of field otherwise not much of their macro photo will be focused.

I'm also a macro newbie . May I know if flash is necessary when shooting macro?

When shooting landscape in daylight, is it necessary to use flash?

On the subject of DOF, correct me if I'm wrong:
Bigger Aperture (small F no.) = smaller DOF
Smaller Aperture (big F no.) = bigger DOF

Not always. Flash may be required to give more light to:
allow use of smaller aperture
allow faster shutter speed
freeze subject motion
soften harsh shadows

What for??

That's correct!
