Lens Review
Introduction | Tamron 150-600mm f5-6.3 Di VC USD lens performance on 5D Mark III | Tamron 150-600mm f5-6.3 Di VC USD lens performance on 7D | Tamron 150-600mm f5-6.3 Di VC USD vs. Sigma 150-500mm f5-6.3 APO DG OS HSM vs. Canon EF100-400mm f4.5-5.6L IS mounted Canon EOS 5D Mk III: Good overall IQ | Tamron 150-600mm f5-6.3 Di VC USD vs. Sigma 150-500mm f5-6.3 APO DG OS HSM vs. Canon EF100-400mm f4.5-5.6L IS mounted Canon EOS 7D | Conclusion

The same three lenses tested on the Canon EOS 7D reveal similarly that the Tamron is the better performer overall.

However, there isn’t much between them. Peak sharpness is pretty much the same, though at 400mm the Tamron maintains the edge in sharpness (predominantly in the outer areas of the frame) that was seen on the Canon EOS 5D Mk III. Both the Tamron and Sigma have somewhat disappointing sharpness (at least compared to the Canon EOS 5D Mk III) at their maximum focal lengths, however the Canon’s sharpness at 400mm is still good, at least in the centers of the frame (the periphery is noticeably lower). The Canon also better control of CA than the Tamron when compared at 400mm, but it has slightly higher vignetting albeit not particularly noticeable.

Open aperture performance is less impressive on the Canon EOS 7D at 400mm with the Canon lens leading slightly in sharpness centrally, although the Tamron has good uniformity. Unfortunately, sharpness degrades beyond this focal length.
