  • 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 :)

Lens shopping...

I expect most current manufactured lenses by either Zeiss, Angenieux, or Cooke which is intended for ANSI S35 or Full aperture will work with this new 5K sensor size. Most of this glass covers more than the 24.9mm x 18.7mm apertures. If we do the math this puts the minimum image circle @ 31.14mm and in practice I can't think of any specific lenses which are vignetting this image area?

Matthew... nice to have you post here but we have current industry lenses here that do not cover past a 28mm image circle. "Most" is not "all". It is important to check and not assume. There are also new "4K" lenses being released at NAB that advertise a 30mm image circle.

A 28mm image circle will cover roughly 4.5K on Mysterium-X and 4K on Monstro
A 30mm image circle will cover roughly 4.75K on Mysterium-X and 4.5K on Monstro.
A 32mm image circle will cover roughly 5K on Mysterium-X and 4.75K on Monstro. (5K is possible with wide formats- 2.40:1)

And these numbers depend on how much, if any, vignetting you are comfortable with...

Zooms typically have less coverage than primes. All full frame stills lenses will cover the whole sensor, but typically breathe a noticeable amount. APS size still lenses may not cover the full S35 sensor.

Everyone needs to pay close attention to what the are buying and not just assume that all is well.

The right answer is the real one.

We designed the 18-85mm zoom before we decided on the new S35 sensor size.

Hi Jim,

can you also let us know about the image circle on the 300mm Pro? I want to think it does offer the 32mm circle as well, since we're being told that the Pro primes all offer this. it seems large from what I can tell, but have not had it measured.

Thanks :)

I was saying this the other day in a thread on the DSMC General subforum, I made this image showing what I thought would happen with an APS lens that was only exactly big enough to cover APS with no extra room :

I'm glad to see you confirm that I was right. I'm not that smart most of the time :)
 
1st... there is more than one APS standard so not all APS lenses will cover.

Next... our 300mm will cover up to 6K Monstro. Anyone who doesn't own our 300mm should consider getting one. You'll be surprised at what it can do and discover a new way to "see". That presupposes you have the $$$. :-)

Jim
 
Thanks Jim. Perhaps you could clear this all up and tell us which lenses you think will not cover your new sensor. Matthew

It is dangerous territory for us to do that... it is something a buyer needs to do. We walk a thin line between appreciating support from the community of 3rd party suppliers and throwing them under the bus. Plus, if we have bad info... and post it... that would not be good. Additionally, we just don't have time to do this.

Jim, I assume this is true for the original (used to be pro) 300mm and the new "PRO" 300mm?

(For those of us that didn't realize we should wait on buying that lens):violent:

EDIT: I'm not bitter, just gripey on this one thing :-)

The original 300mm and new Pro 300mm are exactly the same optically.

I suppose it has been mentioned already, and if so I am sorry, but has anyone seen Jim's post about Red Pro Primes being better than Cookes?!!

That is sweet. I love 2.4 so 5k on Monstro using Red Pro Primes is great news. I just hope there isn't a lot of vignetting, but why post that if they aren't "acceptable" to a large part of the lens gurus working at Red?

This just sounds bad-ass.
 
Jim,

Did i read correctly that you are finding out about your 18-85mm and its image circle in relation to 5K and 6K?

I would be good to know as i have ordered this lens from RED as well as looking to upgrade to EPIC when it is out, as i am sure many others are.

I was referring to "the industry" and the acceptability of some vignetting. The Pro Primes figures I posted have NO vignetting.

And Mark (OffHollywood) was the one that made the Cooke post.

I know the 18-85mm zoom will do 5K at wide formats... still checking on the actual specs. This lens is an unusual suspect. The vignetting is a slow-rolloff type so it is a bit more difficult to tell where the spec ends and usefulness continues.

However... neither this zoom, nor the Pro Primes (except the 300mm), will cover 6K on the FF35.

Please Make a Sticky.

Please Make a Sticky.

Could you guys put a Sticky for all the Red Lenses with Specs and proper compatibility? Maybe under the lenses section.

I think this would help future buyers on the decision process and stop future confusion.

Thank you.
 
Lobbying for a B4 mount.....what type of cigars will help my lobbying efforts!!

Before you may think to make a decision about purchasing lenses for the next RED cameras like an EPIC-x 5K...

than you should be AWARE of the two main things:


1. There are many PL lenses for S35mm that fit perfect with RED Mysterium ™ Super 35mm cine sized (24.4×13.7mm) sensor

2. There will be the CINE lenses that could (?) cover the size of brand new RED Mysterium-X 5K+... sensor that in the video world

translates to at least 5000 pixels of horizontal resolution and no any S35mm lens can cover that size properly without vignetting...(?!).

In that very scenario only available solutions right now are FF35 (still photo lenses), bigger photo format lenses or you could even ask for

Todd-AO and Super Panavision 70mm cine lenses...

After all that the question arises:

What you would get and what you would loose with that solution (5K+ sensor...)... (?!)

Obviously because of the law of physics that "today" is impossible to reach "speed of S35mm lenses" with the most designs of FF35 and larger format lenses...


Think about all those "issues"...


Today if you buy any of S35mm lenses maybe with that you would not be able to reach the highest resolution in the future RED 5K+ sensors cameras (???!)...

and at the first you would need to use a sort of special made lenses for that new format (something like a brand new RED primes...)

or the second you would need to use FF35 or lager format lenses... a both of them still photo lenses (?!).
