18000 euros and open to negociation , need to sell juste because i have a big project ( buying a house).

Bump 19000 euros for the SR3 and accessories

Hello, Price drop: 21k euros for sr3 package 16k euros for lenses

It seems that I can’t find a way to modify a post , and yes I can sell the lenses separately

Sorry yes I mispoke there is a analog to hd-Sdi converter built in the vlock plate . I did not want to be misleading in anyway , bad mistake .

Hello everyone, I am selling my Arri SR3 in perfect condition and serviced by RVZ in France.

i'm wondering is it not just the high voltage which is important? the way i understood that is the ADC has a Voltage ref which is set up in reference to the high analog signal voltage. Then it divides the Vref/ N bit (res of the ADC), we get the LSB, so if i am not wrong (i have been learning about all this for 2 weeks so i'm not sure). With the LSB i know that if there was info under that LSB minimum voltage it is rendered as black by the adc.? So in a perfect world the ADC never limits the range of the sensor. is it more often that way that the other way around?

HI, i would like to know what is the way engineers set the output voltage of a signal in RAW, their maximum output voltage is set in regard of the full well capacity or the amplifier in pixels or column? Also , After in the A/D converter the voltage reference of the converter is something that can be set or it's its resolution that locks it in a certain range? I'm Belgian, so sorry for my english, i'm not sure i as using the right terms. I'm student in a film school but i'm very curious about sensors, i'm not a pro so i'm just trying to learn.

Indeed, i understood That it has a dual gain amplifyer and two 14bit adc and so arri combines the two in one 16bit linear signal. So arri is doing 12bit raw log from 16bit linear, correct me if i am wrong? I am not trying to say That it is bad or something but Just understand the principles. In fact, my first question is, is it right That if i have a 16 bit linear file from which i did a 12bit log i am Just getting rid of some values in highlight but not gain any precision in shadows and midtones. So if they were 64 values in one stop in the 16bit linear i Will not gain more 'shades of gray' by encoding this stop with 300 values in log? Thank you David for your answers, i read you on this forum for a long time and it has helped me à lot. These questions must seem stupid to you.

Hello Everyone! Sorry my English is bad, I’m Belgian. I have to say I’m new to all this , log etc. I’m in a Film school in Belgium. Often on forums and informations about Log encoding I see that it allows to allocate more code value in the range of shadows by giving the equal number of values in each stop of dynamic range. I think I understand the principles of Log Vs Lin. The fact is linear encoding gives too much code values to the highlight where the eye is not able to see the tiny changes in brightness in the higher stops. But I’m not sure, I understand everything. If the ADC in most of the sensor is working in 16bit linear, so the 10 th stop under full well capcity has just 64 code value. I could do 12 bit log and have about 300 values per stop (I know, It’s not exactly equal but it’s to make the point) but I’m wasting many values since the 64 values I got is all I can get, right? Is that possible to have an ADC that quantizes the analog signal directly in log, would it be better? I red a lot on this forum and on websites but I’m not sure I’m understanding it all. I am not an engineer or anything, I am just curious of understanding the process, If someone could enlighten me?
