Tamron Announced SP 90mm f/2.8 Di Macro Lens for Sony A-mount
The new SP 90mm f/2.8 Di Macro Model F017 delivers the same excellent resolving power and remarkably soft background blur effects. The 9-blade diaphragm retains a nearly perfect circular opening even when stopped down by two stops.
The advanced construction includes one LD (Low Dispersion) glass element that maximally limits the dispersion properties of light. The two XLD (eXtra Low Dispersion) glass elements that correct dispersion properties to an even greater extent. From 1:1, life-size close-ups to the most distant horizon, this new 90mm Macro lens achieves outstanding image quality.
