Just got a new camera - Sony F35

Keith-

You can turn off VF warnings in the menu- but back to your question- yes 5600k gets recorded.

Here is what is happening:
Normally most ccd or cmos sensors are balanced natively to daylight, on those cameras- when you switch to tungsten, you see a 2x noise spike in the blue channel. The f35 is unique in that it is one of the few large sensor cameras where the sensor is natively Tungsten balanced. Im guessing this was done as the f35 and genesis were designed as a film replacement for studio based TV/Films (with many of those at the time shooting fast tungsten film on sound stages).

So theoretically, when you switch the f35 to daylight, your using the DSP to process the tungsten image to 5600k- this makes a spike in the red channel (opposite effect as on daylight native camera) but because you have much more light usually in daylight settings- you shouldn't visibly notice the red noise spike (I dont) but you can notice if viewing an RGB parade.

So back to why the camera is giving you a warning- I think if you were to shoot daylight on the f35 the intended way, you would pretend the camera was loaded with fast tungsten film and throw an 85 filter into the mattebox and get to work outside (very common practice for film shooters). Hope that helps answer your question.

Art adams wrote an article about this and concluded that while using an 85 filter would make more sense, using the daylight preset achieved better results.
 
Of course, after kitting-up with a lot of expensive daylight lights, the F35 likes Tungsten. I lit a big set the other day and went all tungsten just to see--looks great! Footage beats F3 on same set in every way. :thumbsup:
(still love my F3 though).
 
I apologize for any confusion regarding the AJA Ki Pro Quad technical specifications. I'm not sure how Apple ProRes 4444 was left off of the list of supported codecs for the AJA Ki Pro Quad on this page:
http://www.aja.com/en/products/ki-pro-quad/#techspecs

I have contacted the marketing department which manages the web pages to correct this and add Apple ProRes 4444 to the list. Sorry for any confusion this may have caused.

Thank you for bringing this omission to our attention,

LMAO! OK Jon, we'll let you off the hook now! (sorta)
Can you verify that the Quad will record SLOG properly? (values beyond REC709)?
We've had problems with other devices not handling this properly with ProRes4444 and SLOG.
Thanks.

BTW, when is the Quad available for purchase?

Fantastic news Jon,
thanks for being around here.
I bet this toy is going to sell well.
 
The Ki Pro Quad is in the pre-release QA process; it is not yet available for purchase. I will need to verify the SLOG question for the Ki Pro Quad specifically, but I would assume that this is not an issue since the Ki Pro Mini (albeit only capable of 4:2:2) is used with the SLOG output from the Sony PMW-F3 often.

Again, I apologize for the error on the AJA web page that was noted.

I hope this information is helpful,

For those having fun with their F35...

Sony have a little warning light (!) in the viewfinder menu, which can be preset to come on under certain circumstances. You'll find a menu which tells you what triggers it, including the white balance setting. This setting in particular was a very handy reminder for people using the old black and white finder on the HDCAM etc... cameras that they've left their 5600K balance, or filter wheel, in the "wrong" slot. On those cameras you could click a button to see which setting were prompting the (!), but I don't think the F35 has a similar toggle.

BTW, I don't know if you know this, but you can configure the menus that appear on the LCD in the body, so that only the pages that you want are shown. For example I've removed most of the pages and left only WB, shutter speed, and frame rate options. It's much faster to operate this way.

I have never heard of anyone doing it, although I know the SRW9000 was sold as being upgradeable. It was also supposed to get a solid state recorder, which never properly materialised.

The F23/F35 share boards, there is just a different connector depending on the front end.
 
Um... dang.
Anybody ever have a situation where when you turn the camera on you don't get an image? It's been a few days since I turned it on. First time I turned it on I had nothing but vertical white stripes on a black bgrd in the VF. Turned it off, then on again and the vertical white stripes were gone, but I had just blakc. Tried a black balance and it timed out at the R-B phase. It goes through threblack balance and then just sits there on that R-B part, then gives an error that it's timed out.

Did this thing just brick on me?

I think there is a way in the matainence menu to check the Status of the boards- maybe try plugging in the ethernet and going through them? That sucks man, hopefully it's nothing.
 
the only thing is that I have different batteries. I got new ones that are 14.8v 190 wh. Would that be a problem? I've tried thru the IF box and the Lemo pin on the cam. After a bit the camera is saying Fan Max, shut down camera, and various boards are spewing NG errors. Is this battery too hot for the thing? the owners manual says it has an operating range of 10.5 to 17 volts, so I thought a 14.8 battery would be safe.
 
Ah. The fan max was me having fat fingers and setting that accidentally. No further errors on the boards. Was a weird deal. Ran thru the menus in system diagnostics and everything checks out fine. All boards and systems report as good. Still can't get an image and still craps out halfway thru a black balance. Thought maybe it was a stuck shutter, but nope- that pops open on start up.
So... anybody know a place to send this for repairs? I purchased it from The Camera House in N. Hollywood. I could send it back since they'll know the unit, I suppose.

I talked with them before about other gear sales, they seemed really genuine and friendly. I'm sure they will help you out, keep us updated.
 
Keith,

Your situation sucks. Just checking, but have you plugged the camera into an external monitor too? Just want to eliminate VF issues.

I really, truly hope that your situation can be resolved, but I think we all bought these cameras fully aware if anything went wrong with them it was beyond economical repair for us. Especially with bodies floating around for $6,000 or so.

Repairs are quite expensive when it comes to internal damage. The damage I got repairs for a couple of months ago was simple mechanical stuff, but is still cost me a juicy $3000. I hope everything works out for you!
