Sigma Sigma 70Mm F/2.8 Dg Macro Art Lens For Leica L-Mount Macro Lenses

Optimized For Notable Image Clarity At Close Working Distances, The Sigma 70Mm F/2.8 Dg Macro Art Lens For Leica L-Mount Is A True 1:1, Life-Size Macro Lens Well-Suited For Close-Up And Macro Subjects. As A Member Of The Esteemed Art Series Of Lenses, This Short-Telephoto Prime Is Also Distinguished By Its Sophisticated Optical Design That Makes Use Of Two Fld Elements, Two Sld Elements, One Anomalous Partial Dispersion/High Refractive Index Element, And Two Aspherical Elements To Limit Both Chromatic And Spherical Aberrations For High Clarity, Sharpness, And Color Accuracy. A Super Multi-Layer Coating Also Enhances Image Quality By Suppressing Lens Flare And Ghosting For Improved Contrast And Color Fidelity In Strong Lighting Conditions. Additionally, A Rounded Nine-Blade Diaphragm Contributes To A Pleasing Bokeh Quality.

Benefitting The Imaging Assets Is A Coreless Dc Motor That Offers Quick And Accurate Autofocus Performance Along With Full-Time Manual Focus Override. The Physical Design Utilizes Thermally Stable Composite Material For Durability In A Wide Range Of Environments, And A Brass Bayonet Mount Also Offers Rigidity And Mounting Precision.
