I tried shooting the same situation as u did and realised it wasn't big enough on my small digi compact.dRebelXT said:Last time I saw a very nice small spider with a prey on its net, however it's
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
The 180mm need to stand further away from your subject. Sometimes it's gd becos you can don't need to get so close to your subject.sumball said:I dun think there are any obvious diff in quality produced by T90mm and and 180mmL especially you are shooting spider.

90mm couples with tubes is better than 180mm with tubes, FYI. 90mm only needs 50mm tube while 180mm need to couple with 100mm tube.
50mm ÷ 90mm = 1:1.81 magnificationdRebelXT 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?
No need Canon tubes, they are too expensive. Go look for the Kenko, the 25mm tube is about S$80 and they are also sold in a pack of 3 of various lengths, I think about S$150+.dRebelXT said:Oh! Googled, and Canon 25mm Ext costs US$120. Sigh.
The Tamron 90mm is able to shoot 1:1 without any extension tube, just double check again on my lens.Terence said:50mm ÷ 90mm = 1:1.81 magnification
If you wanted 1:1 for a 90mm, then it's 90mm worth of tubes you need to stack on.
