In this video I put the Kase 85mm f/1.4 through real-world portrait shooting and break down what matters for this kind of lens: build, handling, autofocus, and optical quality. This copy was a loaner from SLR Revolution and Kase, and by the time you’re watching this it’s already been returned—so this is purely my experience after testing it. Right away, the big “Kase” advantage is obvious: they’re a filter company, and the magnetic filters fit perfectly. For portraits, that slight glow/softness from something like a Black Mist or Dream filter can be exactly what you want, and on this lens it’s basically a plug-and-play setup. Build-wise it’s a nice metal/plastic mix with well-dampened focus and aperture rings, plus a de-click switch, AF/MF switch, and two function buttons. It’s also compact for an 85/1.4 (72mm filter thread, 580g) and balances well on Sony bodies, relying on in-body stabilization (I was getting stable shots around 1/20–1/15). Optically, it’s very sharp wide open (not quite Sony GM2 “critically sharp,” but still very sharp), and chromatic aberration is basically a non-issue—lateral is nowhere to be found and longitudinal is just a tiny smidge. The main drawback is autofocus confidence: after the firmware update it’s much better, but it’s still not Sony/Sigma level, so I’d call it a killer value for portraits, not a sports lens.
