Inside Sigma’s Vision: LensVid Interviews CEO Kazuto Yamaki at IBC 2025
Lensvid sat down with Sigma CEO Kazuto Yamaki — here are a few key takeaways:
1. 2025 Lens Lineup
- Nine new autofocus lenses: 200mm f/2, 12mm, 17–40mm, 300–600mm, 135mm f/1.4, 20–200mm, plus two cine zooms (28–105mm, 28–45mm).
- Small, motivated R&D team of photographer-engineers; long tenures enable efficient development.
- Market is saturated; innovation is essential for adoption and survival.
2. 135mm f/1.4 Highlights
- First 135mm f/1.4 AF lens on the market, about 1.4 kg.
- Challenge: top optical quality while keeping size and weight reasonable.
- No optical stabilization; relies on camera IBIS which performs well up to ~150–180mm.
3. 20–200mm Zoom
- Versatile travel range starting at a very wide 20mm; addresses users accustomed to smartphone wide angles.
- Aim: high optical quality with useful close-focus at some focal lengths.
4. Cine Lenses (Autofocus)
- Two AF cine zooms (28–105mm and 28–45mm) inaugurate a mirrorless-focused cine line.
- No immediate plan for cine primes, but strong customer interest may influence future development.
- May reuse still-lens optics if they satisfy video needs (e.g., minimal focus breathing).
5. AI and Industry Outlook
- Current AI termed “baby AI”; role will grow but creativity remains human-led.
- AI creates from existing data; truly new, innovative work still requires human creators and real cameras.
Key Takeaway: Sigma is aggressively innovating with passionate engineers, launching bold optics while keeping human creativity at the core.

It’s finally happening — the Sony A7V has just been registered in Indonesia!

The Indonesian certification agency has registered a new Sony camera under the code “WW824259.” The device is manufactured in Thailand, just like the current Sony A7 IV. This model is almost certainly the upcoming Sony A7 V, which is expected to be announced in mid-November and begin shipping around January or February.
I still haven’t been able to confirm whether the A7 V will use the same 33MP sensor found in the A7 IV. Below is a photo of me doing my best to convince Sony to give us a new 33MP partially stacked sensor for the A7 V :)

Here is the leaked image of the Sony A7V I posted two weeks ago:

Amazon Prime deals will end on midnight at Amazon US and Amazon Canada. in EU at Amazon DE, Amazon UK, Amazon FR, Amazon IT, Amazon ES, Amazon NL, Amazon SWE, Amazon PL. In Asia/Oceania at Amazon Australia.
Sony A7V shipment start in Q1 only!

Following the announcement of the excellent 100mm GM macro lens, it’s time to prepare for what could be the highlight of the year: the Sony A7V!
While the exact launch date hasn’t been confirmed yet, three reliable sources reported that Sony has informed the camera shipments will happen from Q1 only. This means that at best we might get a Sony A7V announcement in mid November.
Sony A7V specs known so far:
- Leaked image seems to suggest it has 33Mps sensor (we don’t know if it’s a tweaked A7IV sensor version or a new partially stacked)
- new AI chip like the Sony A1II
- Same Sony A7rV body design. This means same 4 way fully articulating screen and same controls
- It does NOT have the Sony A1II/A9III grip design
- price close to $3000
- Announcement likely in November at earliest with shipment start in January/February

Hope to be able to share more info soon ;)
