I think the exquisite  shade of colors here you are delicately showing when shooting wide open and close.

Very nice shot.  I've heard a lot of good things about the Vivitar 90mm f2.5 -- but... 

There were at least two versions of this lens (Vivitar also sold 90mm f2.8 macro lenses).  One of the f2.5 versions was made by Komine (serial # starts with 28), and does not need an extension tube to reach 1:1.  Another is a Series 1 made by Tokina (serial # starts with 37) which does use an extension tube.  Is yours one of these?

I've got the Vivitar 55mm f2.8 macro (made by Komine) and the Vivitar Series 1 105mm f2.5 macro (made by Kiron).  Both focus to 1:1 without the need for an extension tube.  I've never used either on my digital cameras, only because I have extremely nice Minolta bellows lenses.  Thanks for giving me the idea!

Using a manual focusing lens in macro work, not only saves money over auto-focusing optics, but manual focus is essential in macro work.

El mío es el fabricado por Tokina.

Me gusta bastante pero desde que tengo el Sgima 105F2.8 DG DN ART no lo uso.....
