100 - 251?
 
Hey people

What is the real differnece that is sparked between these cameras, all i can tell on other sites is that the 251, has a HDMI port ... is that the only difference? or are there some other ones i dont know about?

Any help would be much appreciated! Thanks

60p and the ability to flip image for lens adapters.


Those are the few I know.

Thanks Ted,

But what do you mean by flipping the image?>

Ted Ramasola June 27th, 2007 04:04 AM

Jim,
The HD200 series incorporates a menu feature that will rotate the image in the LCD and VF around 180 degrees.

If you use this cam with a 35mm lens adapter, or in my case a 645 lens, you wont need another monitor thats mounted upside down to view the inverted image of several lens adapters found in the market today.
The PS technik mini35 and the letus flip already has a right side up image.
The redrock, brevis and SGpro currently does not. Though they are making flip modules soon.

Im using the HD100 and I have to physically rotate my VF and or attach another monitor to view my shot with my lens adapter attached.

Ted

I understand now. i was just looking the 35mm adapter, so you use a 645 adapter, what lenses do you have? sorry for all the questions btw, but your really helping me get a better understanding

Ted Ramasola June 27th, 2007 05:02 AM

Jim,

I use my own custom built lens adapter utilizing the mamiya 645 lenses.

I have an 80mm f1.9 45mm f2.8 and a 150mm f3.5.

Jim,

There is no HDMI port on the HD251 or any ProHD camera for that matter. Only the BR-HD50U deck has a HDMI port.

The HD250 and HD251 do have a SD/HD-SDI out, as well as genlock/aux in and timecode in/out.

There are of course many other differences between the various models.
Please check out this chart for the basic differences.

Here is an explanation of SDI and HD-SDI:
http://en.wikipedia.org/wiki/Serial_Digital_Interface

In short SDI is a type of connection, like USB or parallel or serial... on computers.

SDI is used in professional environments where high data rates are used. For the consumer and individual professional using the prosumer camera Firewire is the typical interface. SDI adds considerable cost. The new middle-ground between firewire and SDI is turning out to be HDMI. Here is an explanation of HDMI:

Thanks Jack, trying to read this article... im such a dumbass, i havent the slightest clue what half of these expressions mean,

"is standardized in SMPTE 292M; this provides a nominal data rate of 1.485 Gbit/s. An emerging interface, commonly known in the industry as dual link and consisting essentially of a pair of SMPTE 292M links"

I mean i prob sound like an ass, but that makes no sense to me. like teaching a monkey to read shakespear

Hey Jim, all you really need to know is that SDI is the preferred input/output format of boutique post houses and dedicaded professionals who make a living doing this stuff.

Other options are HDMI, Component, firewire, and S-video. Sometimes composite.

100 - 251?
 
In conference terms, 'True' HD projectors seem to be the new kids on the block.
SDI is fantastic for AV companies, one BNC cable, sorted!
Of course, this is for 'Live' stuff, but, in my own humble experience, this is what most conferences, seminars, etc. do...
I also hate the word 'Boutique'

Jim Heru June 28th, 2007 07:03 AM

Thanks Jon and Justin, you've really made it alot more clearer!
