p.1 #1 · Sigma 50mm f/1.4 CL DG - new line of lens!
Nice. I'm happy to see new line coming up in Sigma lens.
This new Sigma 50mm f/1.4 CL DG, looks amazing, 56mm long f1.4 lens!
I'm guessing CL means Classic Line?
They added distance scale, amazing metal body like in I series.
Now I'm hoping for more CL lens. Some wider first? I hope?

Having 5 of the Sigma DG DN I Series for Sony, but not the 50mm f2, this looks enticing to me. It's smaller than the 50 f2, but weighs 30g/1oz more, probably due to the Rotary AF system.

Is Sigma the first lens maker that is going to get it?
Nobody wants bazooka zooms and MAssive 1.2 primes anymore- Thats the old guard. Its only the only reason I truly love M mount- A 35 1.4 is a package you can barely notice. I am buying this as soon as I can-

I looked at the sample gallery - the look and feel of the images remind me of my old Mamiya RZ lenses. Their description is apt: "softness, dimensionality, and warmth" but softness doesn't feel murky. If they come out with a short-tele it would rival my Batis as my portrait lens. Whoever came up with this at Sigma nailed it.

I also have 4 of the Sigma I-Series lenses (35/2, 45/2.8, 65/2, 90/2.8) but I didn't pick up the 50/2. Also used to have 24/3.5 and 20/2 but I've traded those away. I'm very interested in this new 50/1.4 and will likely get one as long as the price is not getting too high. I already have lots of 50mm primes (mostly MF) but this looks like an interesting and unique addition to my AF lens set.

I wonder what is this focusing mechanism - apparently helped to reduce size of the lens.
Here's some detail from DPR's article:
The lens’s focusing system is also built for compactness. Rather than focusing internally, Sigma says it uses a “new whole-lens extension focus.” The company is also driving focus in a new way, taking the coils and magnets from its linear motors and arranging them in a circle to create a “slim, high-torque autofocus mechanism.”
According to Sigma, this also lets you immediately switch to manual mode just by turning the focus ring (which happens to have hard stops at infinity and minimum focus distance), even if the lens is focusing, rather than needing to flip an AF/MF switch. However, the company also says it can wobble a bit, thus won’t be as well-suited to continuous autofocus for video.

The images from this lens have an interesting look that won't be for everyone but which I happen to like. In the sample gallery, it appears softer than the i series Sigma 45/2.8, which is my favorite lens, and softer than the "rounded sharpness" that Zeiss named and that I think they achieved in the Loxia and Batis lenses.
I will wait for a couple of well-done reviews and to see some more sample galleries, but I think I would like this lens for its rendering and the for the way its size (and perhaps its weight?) would fit on an A7CR.
When Sigma describes the focusing mechanism as involving the movement of the whole lens, does that mean the lens barrel moves forward and backward during focusing?
