FS5: Operating Hours

What conclusions can I draw from the operating hours of a SF5? What is considered excessive? Can one draw some conclusions about the life of the OLED? I am asking because I have recently acquired a used FS5.
 
Not sure on the FS5's, our FS7's had 500+ when we sold them, and our F55 has 750+ and still going strong. With no mechanical parts to speak of, I would expect these cameras to go for a very long time before they start having faults.
 
Operating hours used to have a significance back it tape days where there were many moving parts that were costly to replace and repair like the video head tape motors etc. modern cameras have little to no moving parts the fs5 doesn't even have a mechanical ND. It's almost wiser to judge a camera cosmetically (water damage etc.) production companies have a early release of c300's that have thousands of hours on them and are still going and will continue.
 
Hours don't mean what they used to. I think my F55(and it has the OLED VF) had over 1,000 hours on it already, when I bought it two years ago. You will probably have moved on from the camera(several times over) before the VF would become unusable. LED and OLED VF's don't degrade anywhere near as fast as our old CRT's. I think OLED TV manufacturers rate life expectancy between 50K-100K hours, if that tells you anything.

I'm not sure if this is the most relevant information (much as I wish it was!). Although the LIFE of OLED displays may well be this high, the major challenge with OLED viewfinders is burn-in of areas of static contrast (i.e. overlays, which remain largely static, despite the image displayed changing.

I'm not speaking from a vast technical knowledge on the subject of OLEDs, but rather from my own experience with the Zacuto Gratical. I had my first EVF for two years before upgrading, and by the end of that time there were clearly visible 'ghosts' of the data overlays visible, even when they were switched off. Whilst I have no idea if the Gratical OLED performs the same as the FS5 internal VF, I also have no reason to imagine otherwise!

Of course, the main determining factor on the condition of the OLED is not actually the operating hours per se, but rather how much of that time the data overlays were switched on. I'd say it's a suck-it-and-see situation. If you point the camera at a solid colour, with the overlays switched off, do you see any ghosting?

Interesting anyway,

The cameras own oled isn't effected by display overlays as the pixels shift to avoid burn in. 3rd party oleds do so it's smart to limit usage of camera display on them the oleds own display characters don't burn in as they are able to shift pixels .

Fascinating. Genius idea that seems completely obvious now you mentioned it.

Seems like it would be a worthwhile feature to include the pixel-shifting overlays when piped out of the SDI or HDMI to an external monitor too - no? I think I might mention it over on the Sony boards as a FW update request. I wonder why it's not standard?

I guess it's not as if there aren't many other 'obvious' features that could've been implemented in the FS7/5 FW that haven't!

Thanks for explaining,

I learned the hard way by burning in on my first EVF and I now tend to have all the display on there FS7 monitor while keeping the graticle clear. Check with Zacuto they have a burn in cleanup for a fee i believe it was around $400.
It would be great if there was a pixel shift going out on the SDIs and HDMIs but Im not holding my breath.
