An old projector lens, fast, but flat in sense of contrast, color, CA, etc.
Needs a lot of PP ... but not bad for a $5 lens.
thanks for looking. |

thank you. Received both lens and rings, a quick try (only converted to JPEG, nothing added). I see some vignetting but colors are vivid. I cannot focus more distant than this, the back lens hits the body, but maybe is the right distance for portraits (I have to wait my wife for testing - babies are too quick for manual focus at f/1.2 ).

Pictures are straight from the camera (except conversion). The orange tint may be due to sunrise (windows on my right, East), I will check in some other time of the day. Bokeh is smooth. Natural vignetting is very nice; this is on Nex 3 (so less than on A7r). Also DoF is slightly less impressive in my pictures due to crop sensor.
The first picture after adding clarity and white balancing:

well, if you had to add contrast and so, there is indeed some difference, because I don't think is needed with my copy. Maybe also interaction with full frame could be an issue? _________________

Guys, I am confused. Received that projector lens (Bell & Howell 51mm f1.2) and can have an image in focus at a distance greater than 20cm if only touch the interior of my NEX-5N with the back glass of the lens. How did you manage to make your images, the great topic starter's portrait, those of children or of the rose, at a distance which seems to be 1.5 meter and more?
Here is a sample with a custom adapter, flange distance at around 30mm:
And here is a sample of the maximum protrusion into the NEX body when the lens barely touches the sensor, so the flange distance is around 3-5mm:
The magenta light "leak" comes from the hole which remains when you insert the lens directly to the body.
How could the flange distance be less than 5mm for a lens destined for 16mm film projection?
Otherwise the image delivered by the lens is a real pleasure. |

Hi Alex, I don't remember exactly how far was the back element from the A7R sensor, but pretty close for sure. If memory serves me well the max focusing distance was about 1.5m ... that's all I can tell, ... sorry have no idea why your lens doesn't focus further. |

"Thorium coated" does not exist, it was used as an add on to the glass mix to achieve a higher refaction index. _________________ Klaus - Admin
