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:
Pros
- 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
Average
- 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)
Cons
- 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)
