Japanese manufacturer Sigma's new mirrorless BF camera is freaking unibody. It is machined out of a single block of aluminum, and the milling process reportedly takes seven hours. Why? Does this make the camera take better pictures? Is it easier to use? No. About the only tangible UX benefit is that the camera is lightweight, at 15.7 oz with the battery; the competing Canon EOS R3 and Nikon Z9 weigh more than double and triple that, respectively. The interface has been minimalized, with just three buttons, one dial, the trigger and the power button. The BF may give heavy shooters storage anxiety; the camera features no SD card slot. Instead there's 230GB of internal memory, which the company says can store "more than 14,000 JPEG files, 4,300 uncompressed RAW images or 2.5 hours of video at the highest-quality setting." Transferring is done via a USB-C port. The 24MP camera will launch in April, and will reportedly retail for two grand.
