nice write-up Jeffery.

the simplest way to know whether you can get true life size of 1:1, snap a ruler. then you can calculate how many 'millimeters' captured across the frame.

OK, this is the sample. taken with my AFS 300mm f/4 on stacked with extension tube onto Nikon D90 at the closest focusing distance less than 1m.

so, roughly it has 29mm over there.

D90 image sensor is 23.6 x 15.8 mm.

then 29 divided by 23.6 is 1.22. so I got almost 1:1 magnification here.

Fuiyoh.... too technical for me....



Good writeup never the less....
