35mm sensor in the dvx..

crazy thought here... but i am planning on buying the red one (was thinking of getting an older arri super 16 or russian made 35mm) but im pretty sure red will be the video worlds panavision and i want to take that leap. ANYWAYS.. ill have my dvx getting dusty once i get red so i was curious if anyone thinks a hack would be possible to put a 35mm sensor from a canon or nikon digital camera and work magic to set it up in the dvx...
do these digital camera even have a 35mm type sensor?

let me know what you think

most of them don't, but more than thatthose sensors are not meant to capture 24fps. Im not sure what the hurdles are, but i don't hink it's possible, at least not without probably more money than it would cost to just buy the red.
 
This idea has about as much sense as replacing honda engine with a 32 liter, 10 ton marine diesel.

- original sensor about 6mm, new 36mm wide (fitting problems?)
- lens would cover about 6mm circle in the middle with a decent picture, talk about vignetting...
 
One day and its going to be just around the corner, prosumer camcorders are going to have (if not full 35mm sensor) large CMOS or CCD sensors. IMHO its the way to go. What else can manufacturers do in terms of a better camcorder? When that happen, DOF isn't going to be an issue anymore and everyone can enjoy filmlook video recording.
 
Prosumer camcorders ARE NOT going to have bigger sensors. Why? Buyers (us) do not want to buy bigger, heavier and much more expencive cameras in great numbers. If they did, they could buy them even now (1/3" sensor pro cameras), but they do not. Do we?

Just a decent zoom lens for large format video weights several kilos and costs over $10000. It is not just economy in numbers, also laws of physics. Big sensor (HD) video camera can not be cheap, mostly because of the lens. Electronics might be cheap.
 
I doubt that they will put 35mm sensors in prosumer camcorders. The manufacturers market of users simply don’t want amazingly shallow DOF, even though users of 35mm adapters is growing, a 35mm image/DOF is impractical to the majority of the market.

Yep, most people just want point and shoot. And with a deep depth of field that makes it so much easier to do that. :D Also makes auto focus easier.
 
You got a point there :):thumbup:. too much DOF may knacker the auto focus drive real quick, wouldn't it. hehe...

But (and this is just a thought) why can't they (the manufacturer) opt to make a few models at prosumer level that has full frame sensor? Look at the SLR and DSLR camera. The digital ones aren't any bigger than a standard SLR camera. If they put in a full frame sensor in a camcorder, I doubt this will cause the size of the camcorder to increase in size substantially. Lots of empty space inside anyway. Just a thought and probably wishful thinking.
 
Have you seen the 70-200mm f2.8 zooms for DSLRs? Zoom factor less than 3. Weight 1.6 kg or somthing, cost $3000. We video shooters are used to 8-20x zooms.

24-480mm f2.8? 6 kg, $50000?

If you were content to use only primes, it might be possible.

But, if there were a market, there already would a video camera like that.

a larger sensor has nothing to do with the size of the camera... red is small.

and im not talking about making an average home camera have this technology.
im talking about a mod like andomeda. we send it out.. get it back in a week. its up to a chip manufacturing company to design it and sell it. once designed it shouldnt cost that much to produce and sell

you dont need hd lenses to project on a larger chip.. case in point RED.. you can shoot with any super 16 -35mm cine lens. zeiss, panavision, arri... and i believe i read that if you buy the mount you can shoot through nikkon lenses if you were that broke after buying the body.
 
im telling you guys.. once red hits the market. panasonic will be in a rush to produce a similar camera.. as will cannon.. the price of varicam wont stay where its at thats for sure. i think i have seen it already dropped a little bit.
 
Basically cine lenses ARE HD lenses, and so are all SLR lenses. A lens being HD does not make it bigger, the focal length and speed does it.

In DVX100 we have a 4.5-45mm lens. To make it f2 (which DVX lens is not at tele) the lens diameter has to be 45/2 = 22.5mm. For 35mm sensor the same lend would have to be about 8 times the focal length; 36-360mm. At f2 the lens diameter (the glass, not from the outside) would be 160mm.

As the size and weight grow at third power of the size difference, the comparable 35mm lens would be 8x8x8=512 times as big and heavy...

There goes the size, price, reason...

OK, take DVX100 apart and see what size the chamber holding the sensors is, then put a 4 times bigger sensor there...

word. well it was just a thought. im still on the list for red either way.
 
Can someone direct me to some RED info. I heard of this thing but am interested to know more. I tried searching this forum, no result. Thanks.
 
Had a look at RED. Man that is one high end quality stuff. Simple principle. Compact and HDTV. Surprise P+S never caught on with the sensor method and build one.
 
I am slow I know, but had a read tru some more info on RED in DVinfo and interesting to know that RED is being financed, design and manufactured by none other than Oakley Optic owner Jim Jannard. Didn't know that until today.
