Many photographers argue that one is superior to the other, but is this really the case? In this article, we will delve into the differences between these two lenses, backed by real-world testing and expert analysis.

Introduction

Photographers often find themselves questioning which lens to opt for, especially when it comes to two lenses with similar specifications. After using the Canon 28-70mm f/2.8L USM for a few years and experiencing a sharpness/focus issue, I traded it for the Canon 24-70mm f/2.8L II USM. The testing conducted by DxO Labs shed light on the performance differences, highlighting the 24-70mm as the superior choice in terms of sharpness.

Testing and Expert Analysis

DxO Labs has conducted extensive testing to compare the Canon EF 28-70mm f/2.8L USM with the Canon EF 24-70mm f/2.8L II USM. Both are high-end, well-built lenses with their own unique characteristics. The testing has shown that the 24-70mm offers superior sharpness compared to the 28-70mm. If you prioritize top-notch resolution, the 24-70mm is the way to go.

Real-World Performance

While the 28-70mm is noted to be sharper at f/2.8 in the center, the difference in real-world usage is often negligible. Both lenses offer sharpness that varies across the focal length and distance range. It's important to consider the overall build quality, versatility, and specific needs when making your decision.

Pros and Cons of the Canon 28-70mm f/2.8L USM

Pros: Offers quick and easy access to the 28mm focal length, which some photographers prefer over 24mm. Two primes and some in-between focal lengths provide versatility. Slightly shorter physical length and about 70 grams lighter than the 24-70mm.

Cons: Sharpness may vary, and it may not be as sharp as the 24-70mm at certain focal lengths. Potential focus and sharpness issues that may be challenging to resolve.

Pros and Cons of the Canon 24-70mm f/2.8L II USM

Pros: Wider focal range, providing more versatility for landscapes, architecture, and events. Superior sharpness throughout the focal range. Better macro capability due to closer focusing distance.

Cons: Priced slightly higher than the 28-70mm. Heavier and bulkier in physical size.

Conclusion

Both the Canon 28-70mm f/2.8L USM and the Canon 24-70mm f/2.8L II USM offer excellent performance in different scenarios. If top-notch sharpness is a priority, the Canon 24-70mm is generally the better choice.
