Thanks Lars! Nope, I don't think is will sufficiently cover that 36Mp sensor as this is a FF sensor
with 24x36mm needing at least 41mm image diagonal, and the Pen-F lenses are designed to cover
24x24mm with 34mm diagonal only - too bad. |
Yes, but I wonder if it might be a chance that it almost cover the sensor the way C-mounts do on m43?
C-mounts are also designed to cover a much smaller area than m43, right?

I think the slower tele-lens like Pen-F 3.5/100 or 150/4 will be more likely to barely cover FF although the edge performance may not be good. The Pen-F 2/70 may show some dark corners. If you have a large ground glass(or a focus screen from a SLR), you can test the coverage of your lens without the A7. _________________ https://lensfever.com/

Both of you are sensitive.
Instead of worrying the penf lenses cannot cover the FF, why dont you just use what you have, for penf lenses?
The small penf lenses and the small bodies - that's the point to get penf and small lenses, right? |

Some C-Mount lenses do cover FF and some FF lenses do cover 6x6 an so on so generally there could be chance of course. Easiest way to find out would be to mount one on an analog FF film camera. _________________ I'm not a collector, I'm a tester

When I hold the 60mm against a OM-2 camera I have, I don't see any vignetting looking true the viewfinder. Of course the register distance will not be correct (to long), but do the coverage change if the lens is closer to the sensor? And, is what I see true the viewfinder on this camera 100? _________________ Lars | Manuellfokus.no |

Thx for sharing the link! Not bad really, and longer lenses are probably even better.
Vignetting is similar to a 25mm C-mount on m43. _________________ Lars | Manuellfokus.no |

The 20mm vignettes pretty much. I have not tested the 42mm f/1.2 yet, but my guess is little or none vignetting from 42mm and up. _________________ Lars | Manuellfokus.no |
