The Tamron SP 45mm f1.8 Di VC USD is a 10-element, 8-group construction lens, utilizing two moulded glass aspherical elements and one LD (Low Dispersion) element. Two of the aspherical elements effectively correct the field curvature to ensure planarity of the image plane, while efficiently compensating for spherical and chromatic aberrations to achieve superb uniformity across the field with high-fidelity point spread reproducibility. Outstanding resolution is rendered from corner to corner and the sagittal chromatic flare (a type of aberration that a point image at corners induces a comet tail-like blur), which tends to become prominently noticeable in night scenes, is thoroughly corrected. The LD glass element optimally compensates for chromatic aberrations, which tend to become particularly prominent in fast-aperture lenses in general, and delivers crystal clear images without any residual colour fringe.
