What Buyers Say
Tamron Di III-A B070 17-70mm
The Tamron 17-70mm f/2.8 Di III-A VC RXD lens is widely praised for its sharpness, versatile zoom range, constant aperture, and effective stabilization, making it an excellent all-around lens for APS-C cameras. Users appreciate its solid build quality and value for money, though many note it is noticeably heavier and larger than typical kit lenses, which can feel unbalanced on smaller camera bodies. A few reviewers mention minor issues like chromatic aberration at the longer end and noise from the aperture blades at certain settings, but overall sentiment is very positive.

Canon 3560B002
The Canon EF-S 15-85mm f/3.5-5.6 IS USM is widely praised as the best walk-around zoom for APS-C cameras, offering excellent sharpness, fast and quiet autofocus, and effective image stabilization. Many users compare its image quality favorably to L-series lenses, though some note it is not as sharp in the corners and can suffer from lens creep. A few reviewers experienced autofocus motor failures or inconsistent optical quality, and the lack of a constant wide aperture is a common drawback. Overall, it is highly recommended for those who want a versatile, high-quality single lens for crop-sensor bodies.
Pros
- Excellent image sharpness
- Fast and quiet USM autofocus
- Effective image stabilization
- Versatile 15-85mm zoom range
