  • 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 :)

I just had a quick question, when the scarlet FF35 is released, how will it handle PL lenses that were made for regular 35 or S35 film or chips? i.e. Wouldn't there be some type of vignetting? I've been searching trying to find a reasonable explanation but either i'm too dumb to understand them, or the question hasn't been directly explained. I appreciate it!
 
Hey...I am no genius (first post actually...might not want to listen to me)... but from what I have read, I think you will be able to use a PL lens, but since the image circle is smaller there will be vignetting at 5k. Now...if you window your resolution down to 4k or 3k the image circle will completely cover the active area of the sensor and there will be no vignetting issues!

Only downfall....can't go full resolution :(

If you are shooting canon or nikon now for stills, their lenses should provide full coverage for you with the appropriate mount.

Hope this helps

Thanks Scot,

That makes sense... I will plan accordingly. I guess if I use still lenses tho i'll have to deal with the focus breathing issues but hey... 5k!??! lol

Thanks again.
 
The scarlet FF with Zeiss ZF primes would look fantastic I assume, based on their super sharp performance on the RED one camera.
 
And Zeiss ZF primes has very minimal breathing and a long focus barrel throw, longer than most still lenses. I use them with my 35mm adapter.
 
Yeah, i was just insinuating that when working with such high resolutions do you have to be even more precise because it's such a large and sensitive image (5k projected would be HUGE), OR because it has so much detail could u get away with it breathing more and focusing not having to be spot on?
 
im confused.. breathing will happen the same on a 1080 2k 3k 4k 5k all the same.. just in smaller portions of the lens..but regardless.. the same amount of breathing will occur. There is nothing about being precise.. there is nothing one can do about lens breathing (unless you just dont pull focus) or your using lenses that simply dont breath (optimo= minimal, MP = minimal - none) all still lenses breath.. some less than others.
 
I'm trying to do the geometry in my head but I think the breathing would actually be less at a higher resolution and by resolution I mean larger crop.

If you crop in on lens breathing the breathing should become proportionally more of the frame.

EDIT: Nope. I'm wrong. It would still be the same proportionally too.
EDIT EDIT: Or would it?

If you have a 100mm lens and it breathes 2mm. Then if you apply a 2x crop then the equivalent breathing would be 4mm wouldn't it? Of course the equivalent lens length would be longer so as ... *head spins*

My gut says cropping a breathing lens would be more apparent.
 
no.. it would be the same.. try it out yourself.. 2k vs 4k... the LENS is totally separate.. from the recording format.. cropped or not.. the lens produces the same mechanics. small crop or large full frame. it wont matter.

if you have a 100mm lens and it breath 2mm.. then you apply a 2x crop.. the picture would change (obviously) but you would still breath 2mm.
 
Hi,
I am mainly a still photographer, with no official video or film education.
I'm not familiar with the "breathing" term. I would love if someone here could explain it.
What is it? and why wasn't I aware of it as a still photographer?

Thanks

"Breathing" is a visible zooming effect displayed by a lens when you change focus. If you would like to see breathing in action, take a still camera and set it on a tripod or table or something. Then set up three separate objects to focus on at different distances. Maybe one at a few feet, another at about 15 feet and one more at 25+. Focus on each object and take a picture, without changing the camera position. On your computer flip between the images from closest focus to farthest and back and you will see it. Each lens design is different and some breathe more than others.

As a still photographer, breathing isn't so much of an issue because when you shoot a picture it's just that one frame. With motion / video / cinema, it's noticeable and many people find it objectionable. Or we should say that many people prefer to use lenses that are designed to minimize breathing.
 
Oh OK, thanks!
Apparently I didn't know the "lingo" but I know the problem quite well.
In extreme macro shooting it becomes so severe that it's easier to focus by moving the camera (or lens) on rails instead of using the focus which changes everything.
(or maybe it has nothing to do with the breathing thing...)
