Comparing Olympus 40-150 f4 vs f2.8 lenses


In this article, we will be discussing the differences between the Olympus 40-150 f4 and f2.8 lenses, helping you make an informed decision when choosing the right lens for your photography needs. We will compare the two lenses based on their aperture, image quality, and price, ultimately providing you with the information you need to choose the best lens for your photography.

What is the difference between f4 and f2.8 aperture?

The primary difference between f4 and f2.8 aperture is the amount of light that the lens can let in. The f-stop number refers to the size of the aperture opening, with a lower f-number allowing more light to pass through. In the case of the Olympus 40-150 lenses, the f2.8 lens allows for a larger aperture opening compared to the f4 lens, meaning it can capture more light, resulting in better performance in low light conditions and a shallower depth of field.

Additionally, a larger aperture opening also allows for faster shutter speeds, making the f2.8 lens more suitable for capturing fast-moving subjects and reducing the potential for motion blur in photos.

How does the aperture impact image quality?

The aperture of a lens also impacts the overall image quality, particularly in terms of sharpness and bokeh. A larger aperture, such as f2.8, can create a more pronounced background blur (bokeh) due to its shallower depth of field, making it ideal for portraits and separating the subject from the background. On the other hand, a smaller aperture like f4 may result in more of the scene being in focus, which can be advantageous for landscape and architectural photography.

However, it’s important to note that the quality of the optics and construction of the lens also play a significant role in overall image quality. While the f2.8 lens may have an advantage in low light and depth of field, the f4 lens may still produce outstanding image quality, especially when stopped down for optimal sharpness.

What are the price differences between the two lenses?

One significant consideration when choosing between the Olympus 40-150 f4 and f2.8 lenses is the price difference. Typically, lenses with larger maximum apertures (such as f2.8) command a higher price due to the more complex optics and construction required. As a result, the f2.8 lens is likely to be more expensive compared to the f4 lens.

However, the price difference may be worth it for photographers who require the benefits of a larger aperture, such as improved low light performance and depth of field control. For those with a more limited budget or who may not require the advantages of an f2.8 aperture, the f4 lens may be a more cost-effective option without sacrificing too much in terms of overall performance and image quality.


Ultimately, the choice between the Olympus 40-150 f4 and f2.8 lenses depends on your specific photography needs and budget. The f2.8 lens offers the advantages of a larger aperture, improved low light performance, and greater depth of field control, but comes with a higher price tag. On the other hand, the f4 lens provides a more budget-friendly option while still delivering excellent image quality and performance. Consider your shooting style, subjects, and budget when making your decision, and you’ll be able to choose the lens that best suits your needs.


1. Does the aperture size affect the overall weight and size of the lenses?

Yes, generally speaking, lenses with larger apertures (such as f2.8) tend to be heavier and larger in size compared to their f4 counterparts due to the additional glass elements and construction required. This is something to consider, especially if portability and weight are important factors for your photography.

2. Can I achieve similar results with the f4 lens by adjusting my shooting techniques?

While the f4 lens may not offer the same benefits in low light and depth of field as the f2.8 lens, it is still capable of producing high-quality images when used correctly. By adjusting your shooting techniques, utilizing proper lighting, and maximizing the lens’s strengths, you can still achieve outstanding results with the f4 lens.

3. Is the f2.8 lens worth the investment for portrait photography?

For portrait photography, the larger aperture of the f2.8 lens can provide a more pronounced and aesthetically pleasing background blur, making the subject stand out. Additionally, the ability to capture more light in low light conditions can be advantageous for indoor or evening portrait sessions. If portrait photography is a significant part of your work, the investment in an f2.8 lens may be well worth it.

4. Are there any trade-offs when choosing the f4 lens over the f2.8 lens?

While the f4 lens may offer a more budget-friendly option, especially for photographers just starting, there are trade-offs in terms of low light performance and depth of field control. If you frequently shoot in low light conditions or require a more pronounced background blur, you may find yourself limited by the capabilities of the f4 lens.

5. Can I use these lenses on any Olympus camera body?

Both the Olympus 40-150 f4 and f2.8 lenses are compatible with Olympus Micro Four Thirds camera bodies, providing a versatile and high-quality lens option for a range of Olympus users. It’s important to ensure compatibility with your specific camera model, but in general, these lenses can be used with various Olympus camera bodies for exceptional performance.
