rule of thumb...look at ur thumb 1st...lol...
the flash is another tool to use to get the best pic.
even the nikon top flash sb900....is not even 1/2 the price of a 70-200 f/2.8
i think ur teacher operates the shop u buy ur stuffs from....Lol...no offence
Now let's see. You were shooting your 2nd pic at 200mm. After the crop factor, your effective focal length is 300mm. Using the rule of thumb of 1/focal length, you need a shutter speed of 1/300s. With the 70-200/2.8 VR, the VR gives you more 2 stops. So you'll need a min shutter speed of 1/75s.
The exposure value of your 2nd pic is ISO1600 f/5.6 1/8s. So with the 70-200/2.8 VR, from f/5.6 to f/2.8 you gain 2 stops. Let's say you shoot at ISO1600 f/2.8. Since you gain 2 stops, the shutter speed is now 1/32s, which is still 1 stop away from the needed min shutter speed.
The above assume that the original lens you used to shoot the pic has no VR. If it has VR, then you do not gain the 2 extra stops from VR, and you're now 3 stops away from needed min shutter speed.
So as you can see, buying the 70-200/2.8 VR is not really a good solution to this problem. What is a good solution? Learn how to use flash properly. I have a friend who insist on not using flash even in poorly lit condition, "to capture the atmosphere". And so what happened? He got all blur pics while I got good ones, simply because I used flash. :bsmilie:
How do u know howmuch shutter speed do you need in-order to get a clear picture ? hmm ...

hi..
errr..
what u mean by "So you'll need a min shutter speed of 1/75s"??
how to get 1/75??
cuz if 70 * 1.5 will get 105..
sorry..
i dun quite understand much abt the stop that the VR system has and how it really works..
Heh , i asked my teacher he said he rather i get a 70-200 f:/2.8 then getting a flash ?
Flash is not a preference. It is a necessity.
For better understanding of relation between ISO, aperture and shutter speed, please take a look at this article from me (wrote long long time ago :bsmilie. Try to understand at least from 1-9.

The statement is true only if you do outdoor shoots on a sunny day. If you do not like to use flash, you have no business shooting a DSLR indoors. Flash is not a preference. It is a necessity.
Time to fire your teacher. (hope you did not pay him any fees.)
