too small for my 90mm Tamron. What are the equipments needed to shoot
such small bugs and what's the settings?
I dun think there are any obvious diff in quality produced by T90mm and and 180mmL especially you are shooting spider. You still get 1:1 at their minimum focusing distance. Perhaps the L give you more superior quality but not significant.Snoweagle said:In SLRs, you may want to get an extension tube for further closeness or if you have more money to spend, get the EF 180mm f/3.5L Macro USM with the extension tube. Results will be superb

90mm couples with tubes is better than 180mm with tubes, FYI. 90mm only needs 50mm tube while 180mm need to couple with 100mm tube.
dRebelXT said:Thank you all.
What is the equivalent focal length if I get a 50mm ext tube for 90mm Tamron?
What might be the cost?
dRebelXT said:Oh! Googled, and Canon 25mm Ext costs US$120. Sigh.

If you wanted 1:1 for a 90mm, then it's 90mm worth of tubes you need to stack on.
catchlights said:The Tamron 90mm is able to shoot 1:1 without any extension tube, just double check again on my lens.
Snoweagle said:Even better, get the MP-E 65mm Macro. U get 5:1!
Terence said:The shot above was made with the MP-E 65 at 5x. Not an easy lens to use.
