Specification :
Designed for close distances, the 40mm f/2.8 Macro from TTArtisan is a macro prime offering a 1:1 life-size maximum magnification along with a 6.7" minimum focusing distance. Benefitting both close-up shooting as well as working at greater distances, the optical design uses 8 elements in 7 groups to maintain consistent image quality and sharpness throughout the focusing range. The 40mm f/2.8 has a manual focus design and an 11-blade diaphragm that contributes to a smooth bokeh quality, making it an excellent portrait lens.
