  • 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 :)

OK.. sorry for delay.. heres my cooke 25-250 v zeiss zf test

does anyone know if there is a filter that rounds the picture off?

sharper in a circle in the image, the curved sides fall off a little bit more?

this would be an amazing filter for when you want new glass to feel older...
 
Ironically I like the look of the ZF much better! Thanks for the test...I am going to be ordering our ZF set this summer and have them cine moded like you did....
 
I'm all for doing an effect in-camera as opposed to during post, but I think the "falling off at the edges" look might be a good one for some post filtering, where you can experiment with the degree of fuzziness without baking it in.

Otherwise, some Vaseline on the edges of a clear filter, perhaps?
 
ZF's are really great.. and like I said.. diffuse them a little with classic soft or low con to give them that more organic feel... (or if they have a filter like i mentioned above)

and your set..

zooms are still amazing though.. I really like the flexibility of being able to go from one focal length to the other in a split second.. or even using the zoom function in a shot sometimes. (80's 70's, comedy)

I just posted an OLD short I DP'd/operated..

it was shot with the older cooke 25-250 mk1 and also a red 18-50

The Zeiss looks more ... German (brighter/sharper). The Cooke looks more ... English (darker/smoother).
 
Thanks Zakaree for the comparo :)

I own ZFs and i like them.

In this example, i much prefer the look of the Cooke.

...but maybe it just depends on two things, maybe...

1) For a given T stop, the Cooke is more optimistic :) ie T4 mark = real T4.5
…so the image appears a little darker

2) The color temperature of the Cooke is a little warmer to start with…

…maybe they could match if you set the color temperature a little warmer with the Zeiss.

The Cooke images reminds me so much the good old Canon FD's...really

Thanks for this test Zakaree.

I like the results from both the Cooke and the ZF's but think there is more flexibility to post-process with the images from the ZF's.

For my needs that's why I would prefer the ZF lenses.

Just using a gauss blur may be too soft, but if you make two sets of frames, one normal or sharp and another with a guass or equal blur of maybe 3 to 5 pixels raidus then mix the two together (like double expose, you divide the brightness then at so the sum is 1.0, like sharp at 40% blur at 60%).

To get a ring with a spot like the Astro Berlin, you can make three sets,

A) Sharp

B) Blur to 6 pixels radius (for 4K)

C) Blur to 4 pixels radius

Subtract C from B then add A like this,

((B * 1.4) - (C * 0.9)) + (A * 0.5) = result

Hi,

Cooke measure & mark each lens individually T4 is really T4.

Even on their older glass?

I shot a short earlier this year using two Red's- one with my set of Cooke S2/S3's and the other with RPP's (I could not get a hold of a second set of S2/S3's). To get the two to match, on the RPP's, I put a 1/8 Classic soft, 1/4 Coral, and stopped down the RPP's by about 1/3-1/2 extra. And that seemed to get the lens in the ball park of the Cooke's.

I must say, I LOVE Cooke glass, and I have a special place in my heart for the older glass ...
 
Having shot with a wide variety of lenses on the RED, I have to say that my favorite footage seems to come from the Cooke glass. S4s, and the Techno 18-90 I owned for a while gave very pleasing results, instant cinematic gold. Great results from other lenses as well, including RPPs but a different look. All depends how you're filtering of course, but just straight up I seem to favor Cooke's.

When they left the factory they were correct, if the coatings have been 'cleaned' away or replaced then it's anyones guess.

I don't know how accutare the T stop marks are on the RPP's but there was a HUGE innaccuracy on the 18-50 I tested at a rental house a couple of years ago.

The 2 filters (probably 4 uncoated surfaces) would loose some light.
