The tube and the converter have very different effects and usage.
Tube is making the lens to focus closer while the TC makes the lens appear as 180mm and increases the working distance.
It may even be interesting to combine both.

Hi all
I'm a new member and this my first post.
I've just purchased a Tamron SP90 F2:5 macro plus the Tamron extension tube with Pentax adapter. My question is would i be better off getting a 2 x converter instead of using the extension tube. As i've found that if i wish to use the lens normally instead of 1:1 macro i have to remove the tube, so i was wandering that if i used A 2 x converter then it would always be on the lens and ready to use for other shots when needed. I do hope this makes sense as i've only just started with macro.

Thanks Richard
