I moved over from Sony lenses to Sigma lenses, still using Sony body. Both A9 II and A1.
What is my F2.8 lens lineup?
- Sigma 70-200mm F2.8 DG DN OS | Sports my “money lens” to shoot the ballet performances, Typically from the last row.
- Sigma 16-28mm F2.8 DG DN | Contemporary for architecture photography, theatre interior and exterior photos
- Sigma 28-70mm F2.8 DG DN | Contemporary for backstage and portrait photos
First — Sigma is a high quality lens. I can’t tell which of my photos are shot with Sony GM lenses and which ones with Sigma lenses. The last missing piece was new 70-200mm F2.8, which has the newest focussing technology and it is native construction for sony.
Secondly — I saved 4500 €, which is considerable amount of money.
Third — Sigma makes Contemporary line, which is a lot lighter than Sony F2.8 lenses. Weight and size is a big issue, when travelling. I travel always only with carry-on luggage. Less size and weight is a dealbreaker.
Fourth — Sigma 70-200mm F2.8 is black, not white as Sony 70-200mm F2.8 GM. Black is a much better colour choice when you want to be discreet during the performance.
Why Contemporary, not Art lens line?
Weight and size! Yes, zoom ranges are a bit different, but I am all covered. 16-28 mm is enough to shoot theatre auditorium, instead of pretty heavy and large 14-24mm F2.8 DG DN | Art lens with a huge front element. And 28-70 mm is totally OK, instead of much heavier 24-70mm F2.8 DG DN | Art.
Why Sigma 70-200mm, not Sony GM II?
Sony G Master 70-200mm f/2.8 OSS II is 3000 €, Sigma 70-200mm F2.8 DG DN OS is 1700 € = savings 1300 €.
I actually sold my ver I Sony G Master 70-200mm f/2.8 OSS and planned to buy ver II. But then I found out that Sigma still made direct competitor for G Master and I made a smart choice.
Drawbacks? Yes, some. First, there is no TC for Sigma 70-200mm. Secondly, instead of Hi speed 20 FPS I get 15 FPS using Sigma lenses on my A9 II body. This is the policy, I believe for Sony. They license their mount only to these third party manufacturers, whu accept this 15 FPS max constraint. But this is OK for me. Additional 5 FPS does not add much value for me.
Why I bought 16-28mm F2.8 DG DN?
I used Sony Vario-Tessar T* FE 16-35mm f/4 ZA OSS for interior and exterior shots. But it was F4 and pretty old design. Again, Sony G Master 16-35mm f/2.8 was huge, and expensive 2500 €. Sigma 16-28mm F2.8 DG DN was just 850 €, savings 1650 €.
