Conclusion

The Sigma 35mm F1.4 DG HSM for Sony E-Mount is a very fast, very sharp lens that exhibits low chromatic aberrations and little barrel distortion. Vignetting at wide-open apertures is the only real optical issue of note, something that other similarly fast lenses also suffer from, and stopping down to f/4 solves the problem altogether.

Build quality is excellent, with the brass lens mount and sober all-black design adding to the high-quality feel, and Sigma have even generously included a very good lens hood and padded case. Focusing was quick on the Sony A7R III that we tested the lens with, and manual focus over-ride at any time is a great feature. It is undoubtedly a big and heavy lens, though, given the modest 35mm focal length.

It also has the same lack of weather-sealing and image stabilisation that the DSLR version suffered from, although at least the latter is addressed if you're using this lens with one of the latest generation Sony cameras that offer in-body stabilisation, such as the A7R III that we tested it with.

Sigma have sensibly priced the Sony version of this lens exactly the same as the DSLR version, which in turn makes it much cheaper than its main rival, the Sony FE Distagon T* FE 35mm F1.4 ZA - in the UK, it's less than the price! If you want a signficantly lighter, more compact lens, then the well-regarded Sony Sonnar T* FE 35mm F2.8 ZA is worth considering, but it's obviously a lot slower at f/2.8 and is actually slightly more expensive than the Sigma 35mm F1.4 DG HSM.

So, in summary, the Sigma 35mm F1.4 DG HSM for Sony E-Mount is a fantastic, if undeniably big, lens that outperforms its smilarly priced Sony rivals in every way except for size.
