the Sporti is 6x6 on 120 film with a lens which I think is just a little bit wider than standard for that format. It was not actually marked on my Sporti 6 but I think it was around 75mm. The lens on my 'new' Balda is 72mm, also on 6x6 format.

I think the 'working aperture arm' refers to the fact that the aperture selection on the Holga doesn't actually do anything.
