Hi folks
I just acquired three of these TV-Proclar f1.2 135mm lenses from an old rear projection TV.
Unable to find any info about them, anyone know anything about them or even used one?
They are huge things with 112mm diameter front element. Definitely coated as they have a deep purple colouration, rear focal distance seem pretty short, might be able to trim the barrel somewhat though. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

Make sure it's not the charger. I had a problem with my 10D where the light would flash and then come on full to say the battery was charged, but it wasn't at all. Battery was fine. Charger was b*ggered. |

Just a guess, but, aren't all the lenses designated/marked TV, for TV cameras?
I further guess, it would be closely comparable to a C(Cine) mount lens? |

From the application they are designed for one can make some asumptions:
Fast to give bright image - ok that was simple.
Furthermore optimized for a very high image contrast - but low resolution.
But I am very eager to see images made with such a lens Dreamy background with very short DOF - but is sharpness ok? _________________ Camera modification, repair and DIY - some links to look through: http://www.4photos.de/camera-diy/index-en.html

That's a good thought, perhaps the coatings/optics are specifically designed individually for a particular colour
Come on Ian, get that battery fixed |

Jump start the old one from a car battery - as long as you take the leads off before it gets too warm you'll be OK! |

So how come your next one is on a slow boat from.............. China?
I sympathise. I have managed to revive batteries like this with a jolt charge, but it's never permanent. Once they start to go, that's normally it. |

Pretty sure the three lenses are RGB, especially if its an old project TV.
Any more info how this turned out? Borrow a friends camera for crying out loud! I wanna see how this thing performs (or I might have to go cannabilize some TV myself) _________________ Nikkor

Here are a couple of pics, these are colossal lenses. I think they are for a component video system as they have Cyan, Magenta and Yelllow coloured coatings.
The small lens sat on top is a Canon FL 2.5/35 for scale.

Well, the lenses are in two pieces, I took one apart and there is an optical block that appears to be the lens and a mount which has a strange rear element in it. This element is tinted (in this case, blue) and is flat at the back but extremely concave at the front. It appears the colouration I was seeing isn't the coatings or the lens itself, it's just the rear element.
It is going to be a reall challenge to get one of these working as a camera lens. If I do successfully convert one, I'll convert the other two and offer them for sale here.
I think I might have to email Schneider for some data on these lenses. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

they are aimed at projecting R, G and B colours separately. If the back element contributes to optical scheme (likely it is, since is not just a flat filter), best thing is to use them for b/w. _________________

Yes, I have a feeling they will only work for BW. Rather than being RGB, they are Cyan, Magenta and Yellow. Component video can be either RGB or CMYK (K being black so is not projected). _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |
