DPReview has published their review of the new Tamron 70-210mm f/4 Di VC USD lens. It seems that they love this lens very much and it is suggested for “DSLR users looking to upgrade their kit telephoto zooms and those wanting to photograph moving subjects in good light, portrait shooters and outdoor events“.
Conclusion from DPReview:
The Tamron 70-210mm F4 represents a fantastic value in its segment. While it isn’t the sharpest option for demanding uses and the ergonomics might turn some users off, the overall image quality, stabilization and inclusion of weather sealing make it a truly compelling option for Canon and Nikon DSLR users.
