What To Know
- However, if you need a more versatile lens with a longer zoom range, a wider constant aperture, and improved autofocus performance, the RF-S 18-150mm is the better option.
- The RF-S 18-150mm is better for portraits due to its wider constant aperture, which allows for shallower depth of field and more flattering subject isolation.
- The RF-S 18-45mm has a wider field of view at the 18mm focal length compared to the RF-S 18-150mm.
When choosing a lens for your Canon RF-S mount camera, two versatile options are the RF-S 18-45mm f/4.5-6.3 IS STM and the RF-S 18-150mm f/3.5-6.3 IS STM. Both lenses offer a wide range of focal lengths, making them suitable for various photography genres. However, there are key differences between the two lenses that may influence your decision. This blog post will compare the Canon RF-S 18-45mm vs 18-150mm lenses to help you make an informed choice.
Focal Length Range
One of the primary differences between the two lenses is their focal length range. The RF-S 18-45mm offers a standard zoom range, covering wide-angle to short telephoto focal lengths. This range is suitable for everyday photography, including landscapes, portraits, and group shots.
On the other hand, the RF-S 18-150mm provides a significantly extended zoom range, reaching up to 150mm. This versatility allows you to capture distant subjects, making it ideal for wildlife photography, sports, or travel.
Aperture Range
Another important aspect to consider is the aperture range. The RF-S 18-45mm has a variable aperture range of f/4.5-6.3. This means that the maximum aperture changes as you zoom, which can limit your ability to control the depth of field.
In contrast, the RF-S 18-150mm has a slightly wider constant aperture of f/3.5-6.3. This means that the maximum aperture remains the same throughout the zoom range, giving you more consistent control over depth of field and low-light performance.
Image Quality
Both the RF-S 18-45mm and RF-S 18-150mm lenses produce sharp and detailed images. However, the RF-S 18-45mm generally has a slight edge in image quality, especially at wider focal lengths. This is due to its simpler optical design with fewer elements.
Autofocus Performance
Both lenses feature STM (Stepping Motor) autofocus motors, which provide fast and quiet autofocus. However, the RF-S 18-150mm has a slight advantage in autofocus speed and accuracy, especially in low-light conditions.
Size and Weight
The RF-S 18-45mm is a compact and lightweight lens, making it easy to carry around. It weighs approximately 130 grams and measures 76.6 x 44.8mm.
The RF-S 18-150mm is slightly larger and heavier, weighing approximately 300 grams and measuring 88.8 x 74.6mm. Its extended zoom range comes at the cost of increased size and weight.
Price
The Canon RF-S 18-45mm is the more affordable option, typically available for around $300. The RF-S 18-150mm is priced slightly higher, usually around $500.
The Bottom Line: Making the Choice
The choice between the Canon RF-S 18-45mm and RF-S 18-150mm lenses depends on your specific photography needs and preferences. If you prioritize compactness, affordability, and good image quality at wider focal lengths, the RF-S 18-45mm is an excellent choice.
However, if you need a more versatile lens with a longer zoom range, a wider constant aperture, and improved autofocus performance, the RF-S 18-150mm is the better option.
