Understanding the Myth of a Large Diameter: Why the SEL85F1.4 is a Premium Lens

In the world of photography, lenses with a large diameter, or more precisely, a large aperture, are often mistakenly believed to be the sole markers of a premium lens. The notion that a large aperture automatically equates to superior quality is a common misconception. This article aims to debunk this myth and explain why the SEL85F1.4, a lens with a small aperture, is indeed a premium choice for professional photography.

Myth Busting: Large Aperture ≠ Professional Quality

Many enthusiasts and amateur photographers tend to believe that lenses with large apertures are inherently superior. However, this belief is often misguided. The quality of a lens does not solely depend on its aperture size. Professional quality lenses have historically been produced with large apertures for a specific reason: lower light conditions. These lenses were designed to perform excellently in low-light scenarios, which were common in the pre-digital era when film sensitivity was much lower (e.g., 200 ISO).

To understand why aperture matters, one must first appreciate the role of light in photography. In the 1960s and earlier, film cameras had a lower ISO sensitivity, which meant that even a small difference in light could significantly affect the quality of a photograph. For instance, in the case of sports photography, a large aperture could mean the difference between a usable shot and a completely blurred image. This is exemplified in the iconic swimming photo of Mark Spitz taken in 1972. The photograph was taken indoors with relatively high shutter speed, and the lack of an adjustable ISO made a large aperture critical for capturing the moment clearly.

The Role of Aperture in Modern Photography

Today, modern digital cameras offer a wide range of ISO settings, making it much easier to capture images in low light. So, does this mean that a large aperture is no longer necessary? Absolutely not! While a large aperture can be advantageous in certain scenarios, especially for wildlife or low-light photography, it is not a strict prerequisite for achieving high-quality results. In fact, shooting at apertures such as F8 often yields better results with less noise and better overall image quality.

The Case for the SEL85F1.4

The SEL85F1.4, a lens from Sony, is a perfect example of a premium lens that does not rely on a large aperture to deliver exceptional performance. Introduced in a 2023 update, this lens is designed for Canon full-frame mirrorless cameras. While it features a fixed f/1.4 aperture, which is indeed large, it is not the primary factor that elevates it to a premium status.

The SEL85F1.4 is praised for its consistent optical performance across its entire focal range. The lens is characterized by its sharpness, excellent color rendition, and low distortion. These qualities are achieved through advanced lens design and superior manufacturing techniques, not solely through a large aperture. The lens also boasts high reliability and durability, making it a trusted choice for professionals who demand consistent performance in various shooting conditions.

Conclusion: The True Marks of a Premium Lens

While a large aperture can be beneficial in certain photography scenarios, it is not the only, or even the primary, determinant of a high-quality lens. The SEL85F1.4 debunkes the myth that a large aperture must be the hallmark of a premium lens. Instead, its premium status is derived from its consistent optical performance, reliability, and durability. Understanding the true marks of lens quality can help photographers make informed decisions and choose the right tools for their creative vision.
