Not all MPEG-2 Long GOP is HDV.
Also Not all Long GOP is MPEG-2 (AVCHD is H.264/AVC Long GOP for example).
Please don't confuse codecs.
Don't confuse codecs? After all you wrote, I'm more confused than ever!

After all it makes sense...

There's HDV1 (JVC Pro HD) & HDV2 (Canon & Sony) and then there's XDCAM.

I wonder if the camera will have an XDCAM logo on the side.

it still says 'ProHD' in the pictures.

Come on though, XDCAM is just a 'better' version of HDV....

I just wish we could mount Nikon SLRs on one of these.... (with out a 35mm lens adapter)

What would you all be happy with for a trade in value from JVC for your HD200/250 bodies?

HD200 - $4000

HD250 - $5000

Just as IMAX is just a 'better version of 35mm.

I'd be ecstatic if I could get $4000 for my HD200! Heck, I'll even throw in my 17X lens.
Don't hold your breath, though.

It's not my approval you need... it's JVC's.

If it were up to me, we'd have pictures all over the place. But I'm not about to risk the associated IP / copyright violations, so the safe and smart thing to do is to respect the wishes of JVC America on this.

Besides, on the day the camera is officially launched, photos will be everywhere... and that date isn't very long from now.

Yes -- these are all part of ProHD product line. I thought we had stated that.

With the PL Mount the JVC HDxxx can utilize cine lenses. I simply wish we could use Nikons SLR lenses with this camera and this adaptor. Without a 35mm lens adaptor (letus, brevis, etc) we can't. Sorry for the confusion.

Unless you want to use Nikon SLR lenses for extreme telephoto effects, you'll always need some kind of relay lens to refocus the image onto a 1/3" sensor. You can buy straight lens adaptors from Mike Tapas (MTF Services Ltd), among others, that will let you attach a Nikon-mount lens onto any JVC ProHD camera (including, I suspect, the new HM700). However, the field of view on a 1/3" chip is roughly 7 times narrower than what you would expect for the equivalent focal length on a 35m camera. So, a 200mm lens on a 1/3" chip looks something like a 1400mm lens would look on a 35mm camera. Very, very cool if you want to shoot wildlife, the moon, or surfers a quarter-mile away. Not so useful for most other things.

Now, if you're asking if JVC could include some kind of relay lens in the body of the camera to reduce that Nikon 200mm lens image to something a 1/3" chip could handle without cropping, that would also be very cool. However, since similar after-market lens adapters run into the thousands of dollars, I expect it would be prohibitively expensive, and would price the new camera out of its intended market.

You've been spending too much time on the Red site! Dream on! I don't recall any major camera manufacturer ever giving a trade-in allowance, let alone 3/4 of the current price of a new camera. Again, would be exceptionally cool of JVC, but I find it hard to imagine.

Brian, does the MTF adaptor address the flange focal distance issue so that infinity focus is possible with Nikon lenses? My reading has led me to believe that the Nikon lens would need to sit INSIDE the camera to allow infinite focus or non-macro focus, depending on where I read.

I don't believe it's a problem with the MTF adaptor. I certainly haven't had any difficulty focusing on infinity with mine, using a Nikkor 80-200mm lens on a JVC HD100.

JVC Korea apparently
As you can see there's the 700 photo, the 100 photo beneath that. The Press Release below that in English.
Apparently JVC is OK with showing the photo.

I can't read it clearly but I think I see 4.4 on the zoom ring, wider than 5.5 on the fuji 16x.

5. Newly developed large LCD display
Comparing it to a pic of the HD200, it looks wider. 4" inch Native 16:9 LCD?

Which would make it NEARLY as wide as the Fuji 18x 4.2... Interesting...

yes the new lens is very interesting

if they market and price towards the 17x end of the scale instead of the 18x Fujinon, it would put a higher quality WA lens into our hands at a decent price and keep the JVC HDPro camera's up there in the video quality game.

Actually, the 18x is a PREMIUM lens. Cost at B&H is over $9000. More than the 13x wide angle. The 16x is of course the stock lens.

And to echo the sentiment, yes, a lens comparable to (or better than) the 17x (and wider!) would certainly be welcome.
