Tamron SP AF 17-35 mm f/2.8-4 Di LD Aspherical (IF)
11. Summary
- sensational image resolution in the frame centre,
- low distortion at focal lengths higher than 17 mm,
- very low coma,
- astigmatism quite well-corrected,
- there’s no problem with vignetting on APS-C/DX,
- good build quality,
- smaller dimensions than those of competitors,
- quite affordable price.
Cons:
- weak image quality at the edge of the field, especially in the 17-24 mm range,
- chromatic aberration from medium to high level,
- too big geometrical deformations at the widest angle,
- a lot of mis-autofocused results.
The Tamron 17-35 mm seems to be a quite good option. An affordable price, a splendid image quality in the frame centre along with medium or good results in other categories and only one slip-up, connected with the weak image quality at the edge at 17-24 mm – all these results allow us to recommend the purchase of this lens. Convinced APS-C/DX format users who don’t plan on doing any full frame swap could decide, however, to buy another Tamron instrument, the 17-50 f/2.8, which fared very well in the tests and would give you even better photographic performance.
