35mm adapters have not gone away for good. You might shudder hearing that statement, but as cameras continue to get even higher resolution, and it becomes harder to differentiate them from each other, there may be opportunities to get an interesting look in the camera by using a tool many of you probably thought was extinct (in this case the Redrock Micro M3):
It might seem like a ridiculous setup, and while it defeats the purpose of the 1" sensor, fixed-lens XC10 on its own as a small camera, it does give you a very interesting look — and of course — lets you get the full view out of your 35mm still lenses. You can get 35mm adapters for dirt cheap these days, so it's not quite as ridiculous as it might seem at first, especially if you were already going to get the XC10 (or you own one).
There are some interesting side effects with using these adapters. Not only do you get your highlights to bloom nicely, but with a spinning adapter like the M3, because the ground glass is not in the same place frame to frame, you're actually getting a look that can't be replicated any other way. In some ways digital cameras were a step back from film because of the fixed pixel design. Only one camera, the cancelled Aaton Penelope Delta, tried to mimic this and increase temporal resolution by shifting the sensor slightly from one frame to the next. Whether or not you're getting that much of an improvement with a 35mm adapter is up for debate, but there is no question it provides an in-camera look that's extremely difficult, if not impossible, to get in post.
