  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

New Cooke Panchros anybody?

well, it depends on if you get the 18mm or not.

The standard 5 lens set 25mm, 32mm, 50mm, 75mm, 100mm runs $33,600.

I got the 18mm as well, but its currently back ordered till the end of this month.

The 18mm adds $8,900 to the above set.
 
The 18mm is well worth it! I didn't think I'd use it as often as the 5-set lenses, but on my last film, I found myself on the lens as much or more than any of the others.

Of course the material and requirements of the particular story dictated such, but none-the-less, I walked off that film and thought, "by god, I can't imagine shooting this two months ago and not having the 18mm."
 
Faster than 2.8?

Faster than 2.8?

Just had a thought: If the irises are hard stopped before opening to full clear glass aperture would there be a possibility to open them up and gain extra stop or so?
Can you guys look inside the lenses and let me know how much of the iris blades you see wide open? Or are they completely hidden?
I know S4s have irises stopped down for baffling the stray light....
I'm willing to go see myself if someone has them in Los Angeles...
 
Jacek, my Panchro/i's have a matte aperture behind the iris... providing nice bokeh wide open. Some of the lenses seem to open a little more beyond that....so, if you removed the mattes you might get a little more.
 
Waterhouse stop

Waterhouse stop

So they have a sort of waterhouse stop beside the iris.
One would have to remove it first and make the iris open wider than the glass diameter to maximize the speed...:coolgleamA:
 
I believe the thinking is these lenses are "pre stopped down" for best performance. Yes technically the iris can open more, but you will probably have poor optical performance "wide" open.

The panchros are tack sharp wide open at T2.8 and stay that way...

Jacek, I don't have a particular reference, but I have heard of someone doing exactly what you just said. they opened up the lens and took out the matte and it opened up to a t2 like an S4, but it was also crazy soft. so it's def doable, but I think the loss in quality out ways the benefits of doing so.
 
Thats AC's..... I'm Talking DP's.

I mean the full knock down drag out, activation of beast mode, for a DOP is lighting a set to a T16. Thank you Gregg Toland for performing a pile-driver on the photon.
