So Christmas is on it's way, and it's time to start coming up with things for my gf and family to buy me (I'm selfish...sue me ;)). I love macro photography, and have the Tokina 100mm f2.8 macro lens and love using it for bugs and flowers. What I want to be able to do is get those amazing, high detail close-ups of the bugs faces that a GIS of "bug macro" always seems to bring up.

From my brief research it seems a set of tubes will allow this. Am I correct? I haven't seen many shots on here that specify it was taken with a dedicated macro with a tube of some sort...just a 50mm (or any regular old lens) with a 12/24/36mm tube. Is using a tube (single or stacked) with a macro lens somewhat impractical, or is it really the only/best way to get those awesome insect headshots?

It'll get you pretty close.

A lot of those guys also "stack" images.

I'm not sure how the calculations work but I can only put so much extension on my 105mm. It moves the pocal point behind the front element.

Cool. I've done the stacking thing which is pretty neat. Now by moving the focal point behind the front element, it basically is making the image un-focusable (very bad) then right? Would a teleconverter serve any better?

Nah just be careful. I think the max I can use on the 105 is 12mm

This guy is on one of the Aus forums and does amazing work. Have a read through his page

Thanks a lot guys! Warus, the opening picture of the link you provided is EXACTLY what I hope to achieve (I'm reading right now so we will see what that actually takes), and Ben I read that earlier, didn't re-search for it so thanks for bringing it to the fore-front. I think tubes should be an adequate addition to my macro lens. These pictures on that site are INCREDIBLE. It's seriously hard to believe how beautiful 'gross' bugs are.
