This one has taken me a while to get to! I was scheduled to review the Sigma 40mm F1.4 DG HSM ART months ago, but then Sigma announced and quickly released a trio of new lenses for Sony FE (and Leica L), which I prioritized covering. The first I reviewed was the little 45mm prime lens. The second of these was thenew Sigma 14-24mm F2.8 DG DN ART wide angle angle zoom, which I reviewed here. The final member of the trio is the beast – a massive optical jugernaut – the Sigma 35mm F1.2 DG DN ART lens – which in many ways is most like the 40mm F1.4 ART that I’m now finally covering. I haven’t yet released my final review of the 35mm F1.2, but I’ll update this once I have. I had an option of reviewing the Canon EF mount of the Sony FE mount version, but I elected to go with the EF version as I’ll be reviewing it not only on my Sony a7RIII and Sony a9 bodies, but also on a Canon EOS R body that I recently acquired to do RF mount lenses reviews on. I grabbed the EF to RF Control Adapter which makes using most EF mount lenses seamless of the RF body. You can get a sense of the lens’ performance from the images below, and stay tuned for my ongoing coverage.
