If it delivers similar quality as Sigma's recent art lenses I'll run to buy it as soon as it's available. I've dreamt of a lens that would cover something like 28-40 at fast aperture... and this is probably even better!
I think I'd find the limited range very motivating. more thinking, less zooming... but still with some ability to change the focal length.
As exciting as all their products are, I wish they've invested a bit more effort in having proper promo videos with examples of the footage shot using all of the products.
My initial excitement for the Pocket Slider is fading out as I wait and wait.
Come on Edelkrone, you can do it!
