Macro Question - Need Advice regarding closeup shots please

yes i have the Sigma MACRO 105mm f/2.8 EX DG, im happy with the resalts its a great lens, i took this picture of a fly, cropped

first shot not bad second shot you have missed the focus abit!

yeah 2nd shot was with my 18-55 lens, without proper fitment just testing it.

will the 18-55mm lens be ok as a reverse lens? as heard people just talking about the 50mm?

also what do you guys thinks the best for closer shots kenko tubes, jessops 2x convertors, cheaper ebay tubes, diopters, or lens.

I'd get a set of Kenko ext tubes - easiest to use and no IQ loss. With the cheapo ebay ext tubes you lose control of the aperture which is a pain. A set of Kenkos will take you to 2:1 max with your sigma.

thanks lordv, can i ask what magnifacation the 18-55mm lens reveresed on my 105mm will take me two? or could i maybe use the 105mm, the kenkos, and reversed lens together for more magnifacation?

i have just got some jessops 2x teleconvertors at a bargain price too can these be used in the mix?

IMO get the tubes and forget about the rest of that stuff. The tubes will get you 2:1 and if you need more magnification you can look into it after that, but for the most part 2:1 is going to get the job done for you.

A cheap teleconverter is going to destroy your image quality.

ok thanks,

so would you say the kenko tubes will give me more magnifaction than a reversed 50mm prime lense on my sigma 105mm ?

Another vote for tubes.

Hard to say what mag the reversed lens will give you. Haven't tried it, but you can! Use just the bare 105 macro lens and min focus distance. You know that's 1:1. Take a shot of a ruler or something. Then add the reversed lens with macro lens and focus as close as you can and take a shot of the ruler and compare.
