Mine needs quite some tweaks in focusing. At 205 grams it has the heft. Material is good while construction is just OK (a typical Chinese impression) - the helicoid feels somewhat rough, the movement like gears grinding. I exchanged for a new one and it improved, but it's still not as smooth as you'd expect from a brand new Japanese lens.
Resolution wise it never gets quite sharp...definitely not up to the CV 35/2.5 and the ZM C-Biogon (surely Zeiss wouldn't call this a "Sonnar" either) 35/2.8 with which the 7 Artisan shares a strikingly similar diagram. I think by making the lens f/2 (plus some other shoddy "improvements") they are stretching the design too far - just like Miyazaki-san did with the double gauss 28/2. Distortion is obvious, artifacts seem to be all over the place, but not unlike the other two "Biogons", on digital it's free from focus shift.
It's cheap, but the blistering sharp and constant CV 35/2.5 is not much more expensive. So at wider apretures it's more like a special purpose lens, fit for utilizing its (may I say LOMO-ish?) signature. Hmm. The same way you'd use a v1 35 lux.
