When it comes to photography, the camera lens is one of the most important factors in capturing high-quality images.

SINGAPORE, Feb 4, 2026 — As the Asia Photonics Expo (APE 2026) kicks off today at the Sands Expo and Convention Centre, Shanghai Silk Optical Technology is proud to announce its presence as a key exhibitor.

If you read the latest marketing brochures in the surveillance industry, you might think anything less than an F1.0 aperture belongs in a museum. The "Full-Color Night Vision" arms race has convinced many procurement managers and engineers that bigger is always better. But let's take a step back and apply some common sense. Buying an ultra-large F1.0 aperture lens for a brightly lit office, a warehouse, or a standard residential driveway is like buying a Ferrari just to drive three blocks to the grocery store. It is expensive, highly sensitive, and completely unnecessary for the task at hand. The truth that lens manufacturers rarely admit out loud is this: For roughly 90% of standard security and monitoring scenarios, a high-quality F2.0 lens is actually the superior, more practical choice. Here is a logical breakdown of why you should stop staring blindly at the F1.0 spec sheet, and why a precision-engineered F2.0 lens might be exactly what your BOM (Bill of Materials) needs.

Talk to any software engineer in the surveillance or machine vision industry right now, and they will tell you that hardware is dead. The current buzzword is AI-ISP (Artificial Intelligence Image Signal Processing). It makes you wonder if traditional optical manufacturing is about to be "calculated" to death by server farms and neural networks. let me give you the reality check that software sales reps won't. AI-ISP isn't going to kill high-end optics. In fact, it is creating the strictest, most demanding "Second Spring" the optical hardware industry has ever seen. Here is why.

In November 2023, the production of various types of lenses (security monitoring, car mounted lenses, starry lenses, etc.) at the direct factory of Shanghai Boshi exceeded 5.5 million. In December, to meet the order demand, new equipment was added and preparations were made in advance for production next year.
