Hello,
We decided to build a light dome at my university, but we are having some difficulties with the lenses. We have a Nikon D7100 camera. One of our options is Sigma 70mm macro lens, it has some good reviews at different websites. However, when we asked a photographer, he suggested that we should use Nikon 105 mm instead. We are planning to photograph fingerprints on clay objects. Since our budget is tight and we don't know much about lenses, any suggestions or reviews about these or possibly other lens options is more than welcome. Thank you all!
