TC will give you a longer working distance but not really more magnification and it will also set you back by 1 to 2 (1.4x or 2x TCs) stop of light. The tube will give you some magnification depending on the length of the tube. Close up filters also will give you more magnification. Both tube and closeup filters will make your focusing distance neared. With tube and/or closeup filter, you cannot focus at infinity whint with TC you can.

Combination of Tube and closeup filter can also be used. Join us for macro shoot and you will learn more than equipment only.

Seriously? Learn to shoot better first. And get the fullest out of your lens. What is wrong with having a 1:1 macro? It can do a lot. And that is probably more than what you can find around most of the threads in the Macros section. I've had my 90mm for years now, and there is still a lot more I can do with it before thinking into add-on gear.

both the extension tube and tele converter let you get higher magnification although on a different contex. The Ex tube "reduce" your focus distance therefore higher magnification. And becuause it has no lens element, it will not affect image quailty in any way. While the TC has lens to magnify the image and will also slow down the lens (eg. if its 2X TC, then your f-stop will be increase by 1 stop). The advantage is you do not have to get closer to the subject (a good thing for insects) to get the magnification....

hope that helps......

correction, 2x tc will lose 2stops of light, while 1.4x lose 1stop of light.
and do note that not all lenses perform well with 2x lens, but there are some which are still very good even with it... ie 28-75 is 1 once stopped down to f4.

You can see the TC and the EX25 being used. Light is reduced, so a macro flash is useful (but not absolutely necessary). I also have a focusing rail on a sturdy head but light tripod, and a cable release. Other than that, a basic setup. For closeup filters, I have not managed to find a 500D for a 72mm thread in stock.

Thks for the nice info abt setup , but i think the setup is too heavy for my wife , all i have now is a sb800 , tamron 90mm , tripod , cable release , will add in a 1.4 tc and a closeup filter too my setup wat do u guys think ?

Just tamron 90mm, SB800, tripod will do. If you need more magnification, can add tc or closeup filter, but the first setup will do mag 1:1.

Arto.
