If you're used to shooting 2/3" CCD video with B4 mount lenses, the conversion factor is 2.5X, so a 7.5mm lens in 2/3" CCD would give you the same FOV of an 18mm on the RED/Super-35.
If you're used to shooting 1/3" CCD video, then it would be a 5X conversion, so 3.75mm would be the equivalent on a 1/3" CCD video camera as the 18mm on a RED camera.
In other words, 18mm is fairly wide-angle.
However, if you shoot in 2K windowed mode, then an 18mm is not so wide-angle.
I agree with the 15mm wider angle perhaps helping in windowed mode, and I'd love to see the 15mm stay as an available lens, but I'm just talking about having a matched set of lenses...
I also generally stay with longer lenses, and usually am using super speeds where the 18 is a bit softer than the 24mm. However, there are times (in tight spaces where I still need some degree of a master shot) where I need that wider lens, and I'd like to get the widest I can while matching the rest of my set.
If I'm also having to shoot wide open I'd hate to have to light to a 2.8 just because I am having to use the wide. Whereas I'd otherwise only have to do a 2.0.
Do you have a notion of which manufacturer could cooke up such a lense? Sorry for the typo! It does however beg the question of how any company could make these high quality lenses so cheaply... economies of scale?
Stephen which one is this? Cooke & ziess are german made, right? I don't know of any UK lense manufacture plant?
"In 2002, the first Cooke lens made for large format photography in 50 years is designed and made in Leicester.
The new Cooke Portrait PS945 lens for 4x5 format photography is a modern reproduction of the vintage
Pinkham & Smith Company's Visual Quality Series IV lens. The first lens of its type is a 229mm,
f/4.5. serial no. 0001 is auctioned at Christie's in South Kensington, London on July 16, 2002 to the highest bidder for 3500 GBP."

That makes a lot of sense then as the red lenses I held at NAB reminded me a lot of cookes.
