Sigma BF vs Sigma fp Specs
Video resolution
The Sigma BF records video in 6K resolution with L-Log support. This format captures a wide dynamic range, allowing for greater flexibility in post-production color grading. The Sigma fp records UHD 4K video at 24, 25, or 30 frames per second. While 4K is standard for many workflows, the BF’s 6K capability provides higher detail and cropping options. If your projects require maximum resolution for large displays or heavy digital zooming, the BF has the advantage. The fp remains a solid choice for standard 4K delivery.
Physical size
The Sigma fp is designed as a compact camera, measuring 4.43 by 2.75 by 1.78 inches. It fits easily into small bags or pockets for travel. The Sigma BF measures 9.1 inches in width, height, and length, making it a large, cube-shaped device. The fp is significantly smaller in every dimension. If you prioritize portability and low profile, the fp is the clear winner. The BF’s larger form factor may appeal to those who prefer a substantial grip or unique aesthetic, but it is much bulkier to carry.
Weight
Weight is a major differentiator between these two models. The Sigma fp weighs just 14.9 ounces, which is approximately 422 grams. This makes it one of the lightest full-frame cameras available. The Sigma BF weighs 9.1 pounds. This is a massive difference, as the BF is over ten times heavier than the fp. Carrying the BF for extended periods will require significant strength or support gear. For handheld shooting or long days on location, the fp is far more manageable.
Build structure
Both cameras use aluminum bodies, but their construction methods differ. The Sigma BF features a true unibody structure, carved from a single block of aluminum over seven hours. This provides unprecedented rigidity and durability. The Sigma fp also uses an aluminum body with a dust and splash-proof design to protect against harsh weather. While the fp is robust and sealed, the BF’s monolithic construction offers a different level of structural integrity. If you value extreme rigidity and a unique manufacturing process, the BF stands out.
Image stabilization
The Sigma fp includes built-in Electronic Image Stabilization (EIS). This feature helps steady your shots, ensuring sharper images and more stable videos when shooting handheld. The data for the Sigma BF does not list electronic image stabilization. Without this feature, handheld video from the BF may rely more on lens stabilization or external gimbals. If you frequently shoot video without a tripod or gimbal, the fp’s EIS provides a practical advantage for reducing shake.
Sensor resolution
The Sigma fp features a 24.6-megapixel full-frame BSI CMOS sensor. This resolution captures detailed images suitable for most professional and enthusiast needs. The data for the Sigma BF does not list the specific megapixel count of its sensor. Both cameras use full-frame sensors, which offer similar low-light performance and depth of field capabilities. Without the BF’s resolution data, we cannot compare the level of detail each can capture. The fp’s 24.6MP is a known quantity for your workflow.
