In this blog post, we will delve into the features and performance of both lenses, comparing their strengths and weaknesses, to help you make an informed decision about which lens would be the perfect addition to your camera bag. So, let’s dive in and explore whether you should buy the Sony 50mm f/1.4 GM or opt for its counterpart, the 50mm f/1.2 GM lens.

Sony 50mm f/1.4 GM vs 50mm f/1.2 GM: Should You Buy?


Sony recently released the new Sony 50mm f/1.4 G Master lens, which has sparked a lot of interest and discussions among photographers and videographers. In this article, we will compare it to the Sony 50mm f/1.2 G Master lens and explore whether it is worth the investment.


Based on the numerous YouTube videos and reviews available, it is evident that the Sony 50mm f/1.4 GM is a stellar performer. Sony has truly excelled in lens manufacturing, surpassing both Sigma and Canon in various aspects. Comparisons with the 50mm f/1.2 GM and the Canon RF 50mm f/1.2 reveal that Sony’s lens is superior in terms of design, weight, size, bokeh, chromatic aberration, and overall sharpness across the frame.

Affordability and Size

When Sony announced the 50mm f/1.2 GM lens, there were criticisms suggesting that they should have aimed for a smaller, more affordable option, similar in size to the 35mm and 24mm G Master lenses. Sony eventually fulfilled these expectations by creating the 50mm f/1.4 G Master lens, which is relatively the same size and weight as the 24mm and 35mm lenses. While it may be slightly larger than those lenses, it remains a reasonably compact option compared to the 50mm f/1.2 GM.

Sharpness and Image Quality

One fantastic aspect of the Sony 50mm f/1.4 GM is its comparable sharpness to the 50mm f/1.2 GM when both lenses are wide open. This means that shooting at f/1.4 on the 50mm f/1.4 GM yields the same level of sharpness as shooting at f/1.2 on the 50mm f/1.2 GM. This achievement is commendable, as the 50mm f/1.2 GM is known for its exceptional sharpness at f/1.2. Therefore, owning the f/1.2 GM and shooting it at f/1.4 results in even greater sharpness.

Is the 50mm f/1.2 GM Worth the Price?

The 50mm f/1.2 GM undoubtedly boasts additional features, such as enhanced autofocus capabilities and other technological advancements, warranting its higher price tag of around $2000. However, for most photographers and videographers who do not necessarily require these extra features, the 50mm f/1.4 GM offers an excellent alternative. The question then becomes whether the additional $700-800 for the f/1.2 GM is justifiable.

Videographers vs Photographers

While photographers may find the f/1.2 GM lens more appealing for its superior sharpness and image quality, videographers often prefer lenses with a certain character and imperfection. They often use filters and techniques to achieve a less clinical and perfect look. In this case, the 50mm f/1.4 GM is more than sufficient for most videography needs. It provides a desirable look while being more affordable and compact.


In conclusion, if you are considering buying a Sony 50mm G Master lens and do not already own the f/1.2 GM, the f/1.4 GM is a highly recommended choice. Its affordability, size, and impressive performance make it a fantastic option for both photographers and videographers. While the f/1.2 GM offers additional features and superior sharpness, the majority of users may find it unnecessary or overpriced compared to the f/1.4 GM. Ultimately, your choice should align with your specific preferences and needs as a consumer.
