The Leica R system, while largely superseded by digital offerings, continues to hold a special place in the hearts of many photographers. Within that system, the 90mm focal length offers a compelling portrait perspective, and the choice between the f/2.8 and f/2 versions presents a crucial decision for serious users. This comparison delves into the key differences, helping you determine which lens best suits your needs and photographic style.
What's the Difference in Aperture?
The most obvious distinction lies in the maximum aperture: f/2 versus f/2.8. This seemingly small difference translates to a significant advantage for the f/2 lens. A wider maximum aperture allows for:
- Faster shutter speeds: Crucial in low-light situations, enabling sharper images by minimizing motion blur.
- Shallower depth of field: Producing more pronounced background blur (bokeh), a highly sought-after aesthetic in portrait photography.
- Better low-light performance: More light reaches the sensor, improving image quality and reducing the need for high ISO settings, which can introduce noise.
Image Quality: A Close Contest
Both lenses are renowned for exceptional image quality, exhibiting the hallmark Leica sharpness and contrast. While subtle differences exist, they're often only noticeable under rigorous scrutiny. The f/2 lens might exhibit slightly better micro-contrast and potentially smoother bokeh at its widest aperture, but these are nuanced distinctions. Both deliver images worthy of the Leica name.
Size, Weight, and Build Quality
Expect a slight difference in size and weight, with the f/2 lens likely being somewhat larger and heavier. However, both lenses share the robust build quality typical of Leica, featuring durable construction designed to withstand professional use. The added bulk of the f/2 lens is generally considered a worthwhile trade-off for its performance advantages.
Price: A Significant Factor
The f/2 lens commands a significantly higher price than its f/2.8 counterpart in the used market. This price difference is largely due to the increased demand for the faster lens and its more desirable optical characteristics. Consider your budget carefully as this could be the deciding factor for many photographers.
Which Lens is Right for You?
The "best" lens depends entirely on your priorities and shooting style.
Choose the Leica R 90mm f/2 if:
- Low-light photography is crucial: You frequently shoot in dimly lit environments.
- Shallow depth of field is paramount: You prioritize background blur for artistic effect.
- Budget allows: You're willing to pay a premium for the enhanced performance.
Choose the Leica R 90mm f/2.8 if:
- Budget is a major constraint: You need a high-quality 90mm lens but have a tighter budget.
- Size and weight are concerns: You prefer a smaller, lighter lens.
- You rarely shoot in extremely low light: You primarily shoot in well-lit conditions.
Is the Leica R 90mm f/2 worth the extra cost?
This is subjective. The f/2 lens offers noticeable advantages in low light and depth of field control, but the f/2.8 is still an excellent lens. The extra cost is justified for those who frequently benefit from the wider aperture, but for others, the f/2.8 represents exceptional value.
Are there any significant differences in sharpness between the two lenses?
Both lenses are exceptionally sharp. Any differences are likely minimal and hard to discern except under very controlled testing conditions. Sharpness is not a defining factor in choosing between the two.
What about build quality – is one lens more robust than the other?
Both lenses are built to Leica's high standards, known for their ruggedness and durability. You won't find a significant difference in build quality that should influence your choice.
In conclusion, the choice hinges on your priorities and budget. Both lenses are excellent options within the Leica R system, providing exceptional image quality. Careful consideration of your shooting style and financial constraints will lead you to the perfect lens for your needs.
