Some cameras have the DOF scale not on lens barrel, but on focusing knob or dial; for example, the Rolleiflex TLR has its DOF scale on the focusing knob; the subminiature camera Tessina has DOF a scale on the focusing dial. Source: Internet
Some TLR had interchangeable lenses but as these had to be paired lenses they were relatively heavy and did not provide the range of focal lengths that the SLR could support. Source: Internet
The advantage of a TLR was that it could be easily focussed using the viewing screen and that under most circumstances the view seen in the viewing screen was identical to that recorded on film. Source: Internet
Thousands of genes are activated by TLR signaling, implying that this method constitutes an important gateway for gene modulation. Source: Internet
