Amateurphotographer has interviewed Sony manager talking about the new a7R IV (B&H Photo Video/Adorama/Amazon). During the interview, Sony manager said they would release f/1.2 prime lens if there is a market for this kinds of lenses. And they will also keep lenses compact and affordable.
Finally, a word about lenses. Sigma has an f/1.2 prime for Sony that is faster than anything in Sony’s own range. Do you see a commercial demand for lenses that fast?
At the moment we have 34 full-frame lenses, covering a wide variety of sizes. There are plenty of fast lenses to choose from, including the 35mm f/1.4, but if there seems to be a market for an f/1.2 lens we will certainly consider it. We’re also keen to keep our lenses relatively compact and affordable.
