Originally posted by UncleVanya Awesome @des Can you also just do one more test? At the short distance range - maybe 2-3 meters max can you show what the effective focal length of the PLM is compared to the DA/L? Use 300 on the PLM and then whatever is needed on the DA/L to give the same field of view? This is very helpful and I appreciate it even if everyone else may have lost interest .
Done. Here are three comparisons in which I have tried to replicate with the DA-L the FOV of the PLM at 300mm: one with the distance to subject at about 1.4m, one at 2m, and one at 3m.
Summary:
- At 1.4m from the subject, the FOV at 300mm on the PLM is equivalent to 210mm on the DA-L.
- At 2m from the subject, the FOV at 300mm on the PLM is equivalent to 230mm on the DA-L.
- At 3m from the subject, the FOV at 300mm on the PLM is equivalent to 260mm on the DA-L
Sequence of images:
1. PLM 300mm, distance from subject 1.4m
2. DA-L 210mm, distance from subject 1.4m
3. PLM 300mm, distance from subject 2m
4. DA-L 230mm, distance from subject 2m
5. PLM 300mm, distance from subject 3m
6. DA-L 260mm, distance from subject 3m
