Analog film photography and cameras

Point taken. However I had a Rollei on loan for a few weeks and it's da bomb, taken some stunning photos. Never used the TLR, any significant differences? Naturally I'm looking to save cash money If I can.

The only real difference with Twin lens rather than Single lens is 'Parralax Error'. This is the difference between the viewing lens and the taking lens, it's hardly noticible when taking wide angles or landscapes, but becomes more of a problem when shooting up close. However if you are aware of it you can clearly correct for it.

There's lots of graphs and diagrams online that explain the exact difference, but it's never been a problem for me.
