SAB: Tamron 50-400mm f/4.5-6.3 Di III VC VXD Review

Sony Alpha Blog posted its full Tamron 50-400mm f/4.5-6.3 Di III VC VXD review, which you can read here or check our the exhibits below:


  • Excellent sharpness wide open in the centre on most of the range (50 to 300mm) , very good at 400mm
  • Very good corners
  • Very versatile lens with 8x zoom : portrait, proxy macro, street, travel, landscape, sport or wildlife
  • Soft background blur
  • Good color rendition
  • Good ergonomics with possible customisation via Tamron lens utility
  • Very Good build quality
  • Very good AF in most cases
  • Low focus breathing
  • Min focusing fistance at 50mm is 25cm allowing to do proxy photography (0;5x magnification ratio)
  • Resistance to flare


  • Weight and size (but better than competition)
  • Price
  • AF for erratic movements
  • Level of CA at 50 to 100mm
  • Tripod collar is optional (129$)
  • Min focusing distance at 400mm : 0,25x magnification action
  • Zoom ring a bit hard
  • Small aperture make ISO climbing fast on the long range (like all 100-400mm)


  • Distortion and Vignetting (but this should be automatically corrected in Lightroom in the future)
  • Gasket for weather resistance too thick making it difficult to mount on some cameras (on my test sample – could not be the case on future samples of the lens)
  • Not Compatible with TC (like all non Sony lenses)
