Analog film photography and cameras

Thanks, took it with this pressed metal beast

Does anyone know what that circular effect you get in the out of focus areas is? I only seem to notice it on cheap medium format cameras.

don't know what the effect is called, but i've achieved a similar, albeit more exaggerated one using an enlarger without a negative carrier - i.e. different parts of the negative are different distances away from the bulb/lens rendering the edges of the photo with this circular blur kind of thing!
