I rented a BMPCC with this lens, and at the same time shot it with the GH-1. There is nothing interesting in this lens. You can have it as a universal wide-angle on some GF5, for example, then you get a compact camera that has an angle of view similar to that of a camera in some kind of smartphone, but the pictures will certainly be better. As for a slightly more serious application, I don’t see any particular point in it - the Panasonic 14-42 whale zoom at the same focal length is a little more than 1 stop darker, but it has optical stabilization (relevant for photos and videos), a similar picture ( in some places it can even be more contrast), and additional focal lengths from "even wider than 17" to a normal, and portrait lens. This lens has no particular advantages over the standard zoom. If the same pan-watering can 25 / 1.4 has both aperture, and pattern, and contrast, and sharpness, and smoothness, and everything that I would like to see in any fixed lens, and I don’t want to shoot it, although 25mm without zoom greatly narrows the creative possibilities , not to mention the lack of stabilization, but they give an image that more than covers all these shortcomings, then the olympus 17mm 2.8, having at least some kind of zoom, makes no sense to buy. The only thing it is useful for is if there is no zoom covering such a focal length, or it is not needed, then you can take a 17mm Olympus and a 25mm panel (for example) and some very tasty telephoto, or a 45mm macro panel - then you can use the 17mm Olympus. As for shooting on bmpcc, in the absence of other lenses, you can shoot with them, but for some kind of serious shooting, or even for yourself on vacation, it will not be enough.
