MiG-25R & -RB cameras?

I struggled over whether to put this in Historic or Modern, but given that some MiG-25 could still be operational I went for Modern…

I have a number of questions regarding the MiG-25R and RB… but I’ll start with this one…

The camera fit for both was 4x A-70M (oblique, unknown focal length) and 1x A/E-10 (vertical, with 1300mm focal length), with other options being 2x A-72 (150mm focal length) or 1x A-87 (650mm focal length)… please correct me if these are wrong. My question is, what format (i.e. film dimensions) were these cameras… especially the A/E-10?

Many thanks

Andy
