Shot my first couple of rolls on the new Fuji and a thing I am noticing is the oval bokeh. I have attached an image below (excuse the absolutely scratched flat-bed scanner, it's all I have access to for now). This was shot wide open, so really the oval bokeh is making no sense to me. Any explanations?
Another thing I have been noticing in my camera is quite a bit of light falloff towards the corners. Is that a thing I just have to get used to on medium format?
I'd love to get more of an insight concerning the optics that are built into this camera, so if anyone wants to share or has a link they can point me to, I'd be very grateful!

It happens quite usually wide open. My 50mm f1.8 does that too until 2.8.
I remember an article about it, here's the link:
http://toothwalker.org/optics/bokeh.html
He describes it as a "cat's eye effect" due to optical vignetting. It's best explained there!

Wow really helpful, thanks! I guess I just never noticed it with my 35mm.

Also, as shown in the first pdf link, if the lights themselves are not perfectly round, the bokeh will not be perfectly round.
