RED 18-85 & Sony F35

[donatello b]

for your INFO ... the RED 18-85 will not mount on the sony F35..
the ears on the PL mount stick out forward a little ( toward lens ) and hit the F stop ring on the 18-85 so you can't seat lens back enough to lock it ( maybe 1/32" off) ...

and i do have to say the Red 18-50 looks excellent on the F35
on my RED when i frame a window i see CA ( lens wide open) around the window frame edges when i focus in/out ( green to purple edges) .. i also see CA using ultra primes, hi speed ziess, cooke 18-100 on same framing ... however when i use the Red 18-50 & other lens on the sony F35 i do NOT see any green/purple edges when i throw focus in/out
i'm not that technical so have no idea why it shows up on one camera ant the other ? maybe CCD vs. CMOS thing ?

has anybody used the 18-50 on the genesis or Arri D20/21 ?
was CA better or worse then when on RED?

any technical explainations why CA would be worse/better on one digital camera vs. another ???

When you say: "I see CA" do you mean in full screen image on just in viewfinder ?

I think the CA issue is about the sensor type...

The CCD used in F35 captures the color information in a different way than the RED Cmos.

This article have some interesting explanations about the differences: http://provideocoalition.com/index.php/aadams/story/non_technical_f35_guide/

The CA isn't about the sensor. I saw Valkyrie last night and I saw CA in that. This is a movie that originated on 35mm film. So how could it be a sensor issue.

Donatello said that the same lens (RED 18-85) show different results in two cameras, one with CCD, other with CMOS... Compare CA in a 35mm film with other lens than that means nothing to me...

Two cameras, same lens, different sensors, one with CA, other without...

I think it has something to do with the internal processing of the Sony camera...maybe.

Good point.

Sony F35 or REDONE ?

i'll go for RED

I've found that often times the RED HDSDI will appear to have more CA due to the down-and-dirty style quick debayer for HDSDI preview. In those cases, when you open up the files in Red Alert or another piece of software it isn't there.

Hey RED@BirnsAndSawyer.com .. you are correct.

on another note.. you better not let Christan see you trying to get away with that username
