The noise at higher ISO levels isn't terribly realistic for modern SLRs, let alone full-frame pro SLRs. Here's a comparison of several modern entry-level SLRs:

You can go up to ISO 1600 and get (more or less) unnoticeable noise.
Note that you have to switch to RAW to show sensor noise-- JPEG mode will blur away noise, trading fine detail for smooth images.
Also that lens is really amazingly sharp at both ends of its aperture range. In the real world you wouldn't get anywhere near that level of performance without spending tens on thousands of dollars on a prime (non-zoom) lens.

- sbierwagen 16y agoIt's a learning tool, and so I would like it to teach that almost all lenses made of mortal glass are less sharp at either end of their aperture range; and that taking a picture of a landscape on a sunny day at f2.8 is a bad idea.
- mortenjorck 16y agoIt's exaggerated, to be sure, but it's an instructive exaggeration. Showing the noise visible in a 4k still at 8% enlargement isn't going to help a novice understand ISO tradeoffs.
