Takumar lenses, made by Asahi Optical Co., are legendary for their exceptional build quality and optical performance. Among the most famous are the Takumar 50mm f/1.4 lenses, particularly the 7-element and 8-element versions. The 8-element lens, often called the “Planar killer,” is celebrated for its sharpness and clarity, rivaling the esteemed Carl Zeiss Planar lenses. This detailed review compares the Takumar 50mm f/1.4 7-element and 8-element lenses, exploring their history, optical design, image quality, handling, and overall performance.
Historical Context
Takumar 50mm f/1.4 8-Element
Introduced in 1964, the Takumar 50mm f/1.4 8-element lens was designed to compete with the best lenses of its time, including the Carl Zeiss Planar. Known as the “Planar killer” due to its outstanding optical performance, this lens aimed to maximize sharpness, contrast, and overall image quality, setting a new standard in the industry. It quickly became popular among photographers for its ability to deliver crisp, clear images with a distinctive character.
Takumar 50mm f/1.4 7-Element
The Takumar 50mm f/1.4 7-element lens was introduced in 1965 as a successor to the 8-element version. While the 7-element lens was more cost-effective to produce, it retained much of the excellent optical quality of its predecessor. The 7-element design was a compromise to reduce production costs while maintaining high performance. This lens continued to be a favorite among photographers for its excellent image quality and robust construction.
Optical Design and Engineering

Takumar 50mm f/1.4 7-Element
The 7-element version simplifies the optical design by using seven elements in six groups. Despite this simplification, the lens maintains excellent optical performance, delivering sharp and clear images. The 7-element design is slightly less complex, which helps in reducing production costs while still offering high-quality optics. The coatings on this lens are also effective in minimizing flare and ghosting, though some photographers note a slightly different character in the bokeh and color rendition compared to the 8-element version.
Technical Specifications:
- Focal Length: 50mm
- Maximum Aperture: f/1.4
- Optical Design: 7 elements in 6 groups
- Minimum Focusing Distance: 0.45m
- Filter Thread: 49mm
- Weight: Approximately 230g
Image Quality
Sharpness and Resolution
The Takumar 50mm f/1.4 8-element lens is renowned for its exceptional sharpness and resolution. At wider apertures, the center sharpness is outstanding, and stopping down improves edge-to-edge sharpness significantly. This lens performs exceptionally well on high-resolution digital sensors, retaining its legendary status even in the modern era.
The 7-element version also offers excellent sharpness, though it is slightly softer at the widest aperture compared to the 8-element lens. As the aperture is stopped down, the sharpness improves markedly, making it a strong performer across the frame. While not as razor-sharp as the 8-element version, the 7-element lens still delivers impressive detail and clarity.
Bokeh and Background Rendering
One of the defining characteristics of both lenses is their ability to produce beautiful bokeh. The 8-element lens, with its more complex optical design, tends to render background out-of-focus areas more smoothly, with a pleasingly creamy bokeh. The transition from in-focus to out-of-focus areas is gradual, contributing to a three-dimensional pop in the images.
The 7-element lens also produces attractive bokeh, though some photographers notice a slightly harsher quality compared to the 8-element version. The simpler optical formula can result in a more pronounced edge to out-of-focus highlights, giving the bokeh a distinct character that some photographers prefer for its vintage feel.
Color Rendition and Contrast
Color rendition is another area where these lenses excel. The 8-element lens offers vibrant, true-to-life colors with excellent contrast. The multi-coating technology used in this lens ensures that colors are rendered accurately, and the contrast is maintained even in challenging lighting conditions.
The 7-element lens also provides good color rendition, though some users note a slightly warmer tone compared to the 8-element version. The contrast is still impressive, though it may not match the higher levels achieved by the 8-element lens. Both lenses handle chromatic aberrations well, with minimal color fringing even at wide apertures.
Build Quality and Handling

The build quality of the 8-element lens is exemplary, featuring an all-metal construction that feels robust and durable. The focusing ring is smooth and well-damped, allowing for precise manual focus adjustments. The aperture ring clicks positively into place, providing a satisfying tactile experience. The overall handling of this lens is a pleasure, making it a favorite among manual focus enthusiasts.
Takumar 50mm f/1.4 7-Element
The 7-element version shares much of the same excellent build quality as its predecessor. It is also constructed from high-quality metal materials, ensuring durability and reliability. The focusing and aperture rings operate smoothly, offering a similar tactile experience. Despite being slightly lighter, the 7-element lens maintains a solid feel, making it a joy to use.
Practical Applications and Performance
Portrait Photography
Both the 8-element and 7-element Takumar 50mm f/1.4 lenses are well-suited for portrait photography. The 8-element lens, with its superior sharpness and smooth bokeh, excels in creating striking portraits with a pleasing background blur. The lens’s ability to render fine details and natural skin tones makes it a preferred choice for portrait photographers seeking high-quality results.
The 7-element lens also performs admirably in portrait photography, offering good sharpness and pleasing bokeh. Its slightly warmer color rendition can add a unique character to portraits, making it a popular choice for photographers who appreciate its distinctive aesthetic.
Street and Documentary Photography
The fast maximum aperture of f/1.4 in both lenses makes them ideal for street and documentary photography, where lighting conditions can vary widely. The 8-element lens’s excellent sharpness and contrast allow photographers to capture detailed and vibrant street scenes, even in low light.
The 7-element lens, with its slightly softer wide-open performance, can add a touch of vintage charm to street photography. Its handling and build quality make it a reliable companion for capturing candid moments and dynamic street scenes.
Low-Light Photography
Low-light performance is a crucial aspect of any fast prime lens, and both the 8-element and 7-element Takumar 50mm f/1.4 lenses excel in this regard. The wide f/1.4 aperture allows for ample light to reach the sensor, enabling photographers to shoot in dimly lit environments without resorting to high ISO settings.
The 8-element lens’s superior optical design ensures that images remain sharp and detailed even in low light, with minimal aberrations. The 7-element lens also performs well in low light, though it may exhibit slightly more flare and ghosting compared to the 8-element version.
Conclusion
In conclusion, both the Takumar 50mm f/1.4 7-element and 8-element lenses are exemplary pieces of optical engineering, each with its unique strengths and characteristics. The 8-element lens, often hailed as the “Planar killer,” stands out for its exceptional sharpness, smooth bokeh, and vibrant color rendition. Its complex optical design and superior performance make it a favorite among photographers seeking the highest image quality.
The 7-element lens, while slightly less complex, offers a distinctive character with its warm color rendition and pleasing bokeh. It provides excellent performance and build quality, making it a valuable addition to any photographer’s kit.
Ultimately, the choice between these two lenses comes down to personal preference and the specific needs of the photographer. Whether you prioritize the ultimate sharpness and clarity of the 8-element lens or the unique vintage charm of the 7-element lens, both lenses represent the pinnacle of Takumar’s legacy and continue to inspire photographers with their timeless performance.
