  • 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 :)

Arri Alexa & RPP

Yes they will work on Alexa.

Jonnycom.

How can you confirm this. There are film camera's on which the RPP glass can not be used based on the fact that it would interfere with the mirror.

Have you tested this?

It's true they won't work with film camera's due to the mechanical shutter i thougth?? But that's not the case with Alexa.

great to know,

this question has been answered so this thread can be closed.

Red Pro Primes can be used on cameras with mechanical shutters except for the 18mm. The A-OV variant of the Alexa has an optical viewfinder so the 18mm is not compatible with it. However all RPPs are compatible with the other two models which have electronic viewfinders.
 
OVF popular?

As vocal as the ovf fans are I think it's on it's way out-certainly for electronic aquisition cameras. There is a slew of OVFs coming due to the DSLR popularity- I know I'm making one. They are getting better and cheaper by the day so the limitations and legacy of OVF have to go...
I think that Alexa with OVF is going to be a very obscure, rare sight..
 
Guys the red flang distance is 52mm but the alexa flang distance is 54mm so how you see this in terms of colimetery dose they need to be colimated every time we use them with epic or alexa?
 
optical is definitely on its way out!!

i was talking with an AC the other day about this.. he was saying "no no no.. optical wont go away.. its what I use", he said..

well hes got 15-20 years on me...
im 27 years old...
When i went to film school, we used a film camera when we were LUCKY.. but the majority of time it was allll digital cameras.. with ELECTRONIC VIEW FINDERS...

its all the new generation knows.. and thus.. it will be the new generation of things

I have used all my RPP's on my Aaton Prod without problem. Including the 18mm

Optical isn't going anywhere, it's still the best way to view an image, through the lens. it's easier on the eye, EVF's are hard work on eyes. For those who can afford the luxury of an OVF, they will have it. If i could have it on my RED for a few thosand more bucks i would, it won't happen, not for that money anyway, but that would be the icing on the cake for me.
 
Robert if you dont mind me asking what is your age group?

the reason I ask is because i see alot of guys who are 35 and up saying the same thing..

but alot of the younger guys who grew up digital, only know digital..
there are a few guys who may have been lucky to go to a real FILM school.. but most schools teach with digital cameras...
and thus thats what we know.

optical is great, but you cant see what the sensor sees.. you cant judge exposure except for a meter.. this is why i think evf's will be more abundant..
obviously guys will still want optical.. but in this day and age.. with budgets where they are... it looks like EVF's will be the future.

The above quote is the best proof for my statement. A big (?) fan of OVF that won't get it. Because you don't really need it. If you really needed it you would get it regardless of the price. Like camera, lens, monitor, media, tripod, etc. The OVF is not on the same list- it's a legacy that finally comes to an end....
 
With a film camera, an OVF is the only way to go, with the alternative being a parallell viewfiender. (they don´t make those anymore, and for a good reason)
With any digital movie camera, having an OVF will only result in you seeing exactly what you are NOT shooting! (as whenever you see an image, the sensor does not, and vice versa) So for digital aquisition, an OVF simply does NOT make sense in my humble opinion. The only market for the OVF is for the old timers who are so used to it, they can´t feel comfertable with an LCD or EVF. (but they will risk making bad decisions based on what they see in the OVF, which will be the images that does NOT reach the sensor)

Then there is the component of possible mechanical failure to the OVF.
 
A digital sensor is like a film stock. You quickly can get used to knowing what its exposure range and sensitivity is. I would never judge exposure by what I see in an electronic viewfinder or onboard LCD, but I certainly can train my eye to know how to expose based on the light around me and what I see through an optical viewfinder. A good DP -- and I don't care if you are 18 or 80 -- can quickly get used to the relative sensitivity and range of the imaging medium he/she is using and then only check the lightmeter for backup.

I've shot several dozen features. For the most part I would pick my combination of T-stop, lighting package and film stock (or electronic sensor camera) in preproduction based on a variety of factors (artistic, economic, logistic, etc.) and go from there. A movie would want a certain relative depth and light level to my thinking and I could plan accordingly. I shot a 35mm feature where my light meter actually broke the first day of principle photography. I sent it off to be repaired and the gaffer gave me occasional readings, but based on the light around me, my familiarity with the lights & stock I was using and what I saw through the optical viewfinder, I knew I could set the lens at my planned T4 and be pretty much spot on. If you train your eye it is not that hard. In fact, I ould say that it is a valuable discipline.

The last thing I want to rely on while looking through the eyepiece is that histogram and traffic light. That's for when I set the lights beforehand and when I'm getting to know the camera and settings I've made. After that I don't want to think about it, as I have more important craftwork to do.
 
You also have to factor that in a bigger union show, the DP isn't behind the camera, he's at the monitors, and often the operators want to turn off any exposure information on the viewfinders as being a distraction. So many prefer looking through an optical viewfinder (less eye fatigue) except for certain camera moves where it is easier to operate with an onboard monitor (and there's nothing stopping you from having both in that case.)

There are pros and cons either way, OVF and EVF (as I said, you can use an OVF and an onboard monitor and get the best of both worlds) but if I had to choose, I'd stick to the EVF for digital cameras just because you need that info sometimes, and it's a good idea to see what signal will be recorded. But it's silly to deny that there are some good things about an optical viewfinder. For one thing, you can line-up a shot without turning on the camera, saving on batteries and not dealing yet with boot-up time.
 
Seriously?!!!!

You are kidding right!!!
Ask any video camera operator- they've been around electronic acquisition much longer than anyone and they wouldn't dare expose without waveform. Exposure is the single most important aspect of electronic acquisition because of the limited dynamic range and the linear nature of sensors. Film let you get away with a murder in comparison....
Looking through a finder and its stop loss, the (unknown)lightloss on GG grain?
Good luck exposing with that!!!:nono:
