Some time ago I decided to check how the depth-of-field and distance-from-subject are for close-up and macro photography using macro rings with high quality tele zoom lens. Now the time has come and I used 52 mm of macro rings, the Canon EF 70-200 f2.8 L lens and the 5d Mk II to photograph this little fluffy guy somwhere in the mountains this spring:
The cute little sad & fluffy guy in the image above is the caterpillar of Malacosoma Neustria (widely known al Lackey moth) and it was very cooperative for this photo session.
The experiment’s result was that neither the dept-of-field nor the distance-from-subject are bigger than using normal macro lens like Canon EF 100mm f/2.8L Macro IS USM. Moreover the big front of the tele-zoom lens tend to be a problem when shooting insects form close distance because the insect tends to move away from such a big object coming so close.
The final results of this insect photography experiment are about 3 mm DOF from around 5 cm distance.
