Sigma's BF Model Minimalist Camera Ditches SD Cards

Sigma continues to make the weirdest cameras for no one in particular.

Sigma made headlines again yesterday with the announcement of its new BF model 24.6 MP full-frame camera body.

The most shocking thing about this camera is not its minimalist design that many camera-heads are comparing to Apple, but rather it's lack of SD card compatibility.

The camera comes with a 230 GB solid-state drive built in, and as cool of an idea as this sounds, this can fill up rather quickly—especially when you consider its 6k 120 fps capability.

And what creator wants to press pause on a project to download files from the SSD before continuing the shoot? *crickets*

It's an inconvenience disguised as a convince. A con disguised as a pro. A cheap trick presented as a luxury.

That being said, the design is rather cool. You can see obvious comparisons to a Leica build type, but even more minimalist. The entire camera has only four buttons and one dial on the back.

The rear 3.2-inch touchscreen display does not flip out and is aided only by the small Status Monitor screen located on the top right—oh and you may notice its lack of a viewfinder.

The actual camera uses a 35 mm full-frame sensor that can obtain a shallow depth of field.

Here's the full specs:

Type: Mirrorless
Sensor: Full-frame 35mm
Resolution: 24.6MP
ISO Range: 100 to 102,400
Display: 3.2-inch hi-res touchscreen
Video Capability?: 6K at 120fps
Mount: L-mount

So who is this camera for? To be honest, I don't see many—if any—professionals moving to use this camera for their professional work.

That being said, it could be a really cool everyday-carry camera. It's basic, and it looks cool (like a cyber truck, Apple Vision Pro, etc.)

If it helps even one person get into photography or videography, then I support it.

But, if we know anything about the Sigma community, we know that they will be up in arms to defend this camera from any criticism—just like their glass ;)

But seriously, I think it's a cool idea with obvious weak points (no SD card slot is actually insane to me) that would ever prevent it from being considered as a "primary camera."

It's listed for $1,999 and should be available by April.
