The poll is now lacking the Pentax 100 DFA WR. Seems based on photos like that is a significant update to the older lens. A lot nicer bokeh in particular.
This poll could be misleading because how many people that voted have used several of the lenses on the list, much less all of them.

Weird,

Nobody mentionned the fact that the Tamron 90mm had is focus outside the body of the lens ? so you have to move back and forth to ajust to the focus ?

The Sigma 105 had a internal focus that don't come out of the body... isn't that important ?

I have hard time focusing with the Tamron, maybe i don't use it well ? any advice?

No, you are wrong:



This is what the sigma looks like when focused to 1:1 with hood and extension tubes. Personally, I shoot macro A LOT and how I focus is first the magnification is chosen by looking through the view finder and than I move my body with camera in hand back and forth until I believe it is perfect. I can't imagine another way

Another way to fine focus with high mag macro is to use a tripod and focusing rail.
