close up filters of +1 +2 +3 +10

[paktire]

hi all,

(repost)

i am using AF MICRO NIKKOR 105mm 2.8 D and trying to get micro shots but not getting good details. the final focus area with FULL focus is around 2.5cm x 2.5cm. whereas i want to keep focus from much nearer so that the super finest details come out.

should i use +1,,,,,+10 close up filters. what filter will be good for insect photography.

thanks.
