Default reverse lens macro - my howto

Thought i shoud make a small tutorial ( or just wanting to share a metod )

I`m into macro ( much more than 1:1 ) and having no money i decided to go on reverse lens.

So .. i took my gf`s 70-300 an 18-55 lens
mounted the 70-300 normally on the camera, 18-55 reversed on the end of the 70-300.

now , please do not laugh, i stuck them together with electrical tape ( rubbery like, colored, 1 dollar thingie ). holds very good, leaves no glue marks.

now .. the actual photography, can`t do field work so you have to bring the critter / object home. - light was provided by 2x 300ws excella studio flashes. ( needed focusing light so i used the modeling light - 2x 60w light bulbs )

Zoom ratios are impresive : camera is a canon xti/450d ( 1,6x aps-c )
300mm + 55 mm = ~8.7 times
300mm + 18 mm = ~ 26x !!!!!!

not shure the calculations are exact, but the result is impresive .. see for yourself :
Fly is ~ 3 mm in length . / the screw is a drywall screw ~3cm overall lenght.

fly is captured at 300mm+18mm, screw at 300mm+18mm and 300mm+55mm.



i think you can see the cells on the fly`s back :|


now the screw .. 300mm + 18 mm / lights @ 1/2 power 20 cm distance



300mm+55mm / lights @ 1/11 power 20cm distance
