ScapingFeet: I'm hoping for a pro consumer uav with a apsc sensor soon. A replaceable lens is a must also.

1" or 4/3rds much more likely. Weight & balance of what your asking for kills it.

Stacey_K: The only part of film I miss was when I was shooting 4X5 chromes. Throwing those down on a lightbox was really cool. Wish I had tried 8X10 when you could still get it.

Just for you:

In reply to:

Pontoneer: This comparison engineered to exclude Pentax K-1 , which could be the winner .

Maybe because the K-1 is under $2K. It doesn't help that Pentax generally has poor video compared to it's competition.

Janoch: Wow!

But then again... hasn't everything been called "ultimate" for the past 20 years?

What will next gen be called? Extreme Ultimate? Hyper Ultimate?

In reply to:

mosc: My only problem is I want that 24-105 f4 as a kit lens. Cmon Sony...

I understand the camera + lens total pricing. Believe me, I looked it up before commenting. I also understand bundled camera+lens packages typically save a couple hundred bucks over buying them separately. Which is exactly my point: A couple hundred bucks in this case is less than 10% of the total. And that is a show stopper for you.

I don't understand: What is stopping you from buying the body + lens of your choice?

In reply to:

Doug Pardee: So... they're saying they found a way to transfer 160 MB/s over the 104 MB/s UHS-I bus? Is that for devices with a standard UHS-I interface, or is that why they added the notation "performance may be lower depending on host device interface"?

What devices could make use of this? And wouldn't they probably just support UHS-II instead? (Yes, there's a hardware difference between UHS-I and UHS-II.)

1. Many, perhaps even most, cameras do not provide the speediest of USB interfaces. The limitations of the camera are of course not the cards fault.

2. Inevitably, someone, somewhere, will put one of these cards into a USB 2.0 card reader, or hook it up to their computer with a USB 2.0 cable, or plug into a USB 2.0 port on the computer and be stunned, shocked, and amazed that they can't get over 34 MB/sec. read/write speed.

In reply to:

Photomonkey: AA batteries are commodities. The only way you can charge more for a commodity is to convince the consumer via expensive marketing that the product is somehow "special".

I remember having my ancient Pentax *ist-DL and K-x and trying seemingly every brand rechargeable AA battery under the sun....non held their charge for even a couple weeks...until I tried Eneloop. Given Eneloops work reliably for years, I am unconcerned about saving a few dollars per decade on batteries.

William Koehler: Correction, Slide 3

"... a video-specific shutter speed of 1/48sec, which will give a 360, 180 and 90 degree shutter angle for 24, 30 and 60p footage. "

A video-centric shutter speed of 1/48sec. yields shutter angles of 180, 225, and 450 degrees for 24, 30, and 60p footage.

@Richard Butler
I understand all of that. It's just not the way the original sentence reads, to this engineer anyway.

By the way, you do a great job. It's much appreciated.

danielw2599: Hope they advertise the write speed more clearly than they did at Lexar.

@BJL
That is the spec. for the ProGrade Card Reader/Writer, not the memory cards.

In reply to:

jhinkey: Now all this needs is a 4x5 digital back with a full 4x5 sensor, something like this:
http://largesense.com/products/4x5-large-format-digital-back-ls45/

Only 12MP, but likely a fantastic 12MP.

Correction: 6.4 Megapixels.

Given the resolutions the MF guys are doing, I would have expected a 200 MP LF sensor, minimum. I find it really hard to imagine someone paying $48.5K for that.

Kiril Karaatanasov: ok Panasonic is bailing from m43 finally!!!

Given the price point and purpose of the camera, I would say no.

In reply to:

Boissez: Don't like it? Don't buy it. Just remember that perfection can be boring to some and more creative options are always good.

The problem is there are already 8mm camera options, from semi-reasonable to dollar-diarrhea. For those who are truly interested there is no need to wait for Kodak.

In reply to:

camcom12: Same is true for Motorola. If a product says 'Motorola', it's unlikely that product is from the original company. They just license the brand. Virtually all the "old-guard" US consumer electronics brands are re-licensed to Asian companies now.

In the case of Motorola, the cellphone division was bought by Google and stripped of its patent portfolio for use in the eternal Google/Microsoft/Apple Patent Wars.

What was left was sold to Lenovo.
