Tamron SP 90mm f/2.8 Di VC USD Macro

The Tamron SP 90mm f/2.8 Di VC USD Macro (F017) is a refined version of a classic macro design, offering 1:1 magnification and full-frame coverage. This 'new SP' version features improved Vibration Compensation (VC) with an accelerometer for better shift compensation at close distances. It uses a USD motor for fast autofocus and has a moisture-proof construction. It is highly regarded for its sharpness and smooth bokeh, making it equally capable for portraiture as it is for macro work. Check the focus limiter switch to ensure it correctly restricts the focus range, which is vital for quick operation. The VC should be tested specifically at close focus distances where it works hardest. SDS examines the internal elements for any signs of haze or dust, though the weather-sealing generally prevents this. The matte finish on the lens barrel is prone to showing minor scuffs, so check for cosmetic condition. The focus ring should be checked for its full travel to ensure the internal mechanisms are unobstructed.
