I totally feel your pain. Which is why I'm still at 11.0.2, which is stable as hell on my PC. :)
Adobe'll figure it out at some point. It's not a great business model but for the kind of work I do (shooting, editing, color, and delivery on a tight turnaround) their system works perfectly.
Tone can be hard to read in comments that is very true. heh.
I wasn't specifically talking about/to you, however, but just the general theme of this thread. These camers should not have been listed in the same article as if they're being compared to each other. They're different tools. That's all I was getting at. :)
Why are you guys trying to compare these cameras in video terms, as if Canon has somehow failed you? It's nearly like comparing a slider to a tripod, saying the tripod is too stationary. C'mon people. I know we all love to complain about something, but these are not aimed at the same use or user.
I know it's nice to think of a camera that can do EVERYTHING we want it too, but as someone who shoots both stills and video for work, I haven't never found that camera, and honestly don't really want to or need to. I like having my solid DSLR for stills work, and I like having my cinema camera for video work. They each have their own accessories and gear and live in different bags.
To each their own, obviously, but I just don't get this outrage.
Also I think one of the main points here is that even though the iPhone shoots 4k, teh Alexa's 1080p still outperforms. This is again, something some of us may know, but with the race for everything to be 4k it's important to have some solid side by side to show that it's not always better. And I'm talking about even real 4k cameras that are for production. Sometimes 4k just doesn't solve things and as someone else pointed out in the comments here, it's good to have that to take to some clients.
I use that lens (as well as the sigma 50-100) on my c100 mk1, and I haven't really experienced this issue. It's possible you just have a bad lens (or, some of these can be recalibrated using software). I never personally trust focus peaking (it has ruined shots for me in the past many times). In general though the Sigma Art series is one of the best lenses for sharpness and built/price I've found, even fairly wide open. So in general, I mean, I would say it's NOT the lens.
If you're shooting at F10 or so, you should be able, for the most part, focus by sight using the viewfinder or LCD and just try that. Also, haze can affect the shots as well. Have you experienced this issue in other locations?
