Correction: Bullwinkle is the CFO, so I have to assume Rocky is the CEO.

SirSeth: Do you think an A7iii is on the heels? That's what I was expecting next. What would Sony hold back to differentiate? Maybe dual SD, battery, and 36mp without the FPS of the A9 or resolution of the A7Riii?

I would bet the A7M3 will stay @ 24MPixel, just as the A7RM3/A7RM2 has stayed at 43MPixel and the A7SM1/A7SM2 has stayed at 12 MPixel. But I'm also hoping it gets the larger battery as a change in body for one likely means a change in body for all. Whether it's the A7 series or A6xxx series, Sony has gotten beaten up for years now about small batteries/poor battery life. I'm hoping the A7M3 also finally gets 4K video with a sensor that doesn't overheat as well.

Not really - They are all very, very good.

User1040523857: What is the real need for a second storage card? They are currently available in huge sizes and almost never fail. Is Video driving this need, or a suspicion that even if you haven't ever had a card malfunction, and your friends haven't either, that there will be one where you need a card that is backing up what is already being stored on your original card? I understand that it is nice to have, but why is it essential? A better solution would be a small battery powered hard drive with communications that could store photos or video as taken in the same way tethered works.

1. Huge sizes - yes video is driving this. If you use the camera to record a locked off shot (seminar, wedding) 4K @ 100 Mbs is about two hours on a 128 GB card.

2. "...and almost never fail". For some, almost is not good enough. Any sort of one time event like a wedding, seminar, concert or legal deposition, or flying to the other side of the world event, be it professional or personal. It's called running all the odds in your favor.

CaPi: High-Pixel-Count 10fps..
PC software pixel shift for even more pixels

Who are you building this for Sony?
The D850 now this?
Hoe many cameras for niche markets does the world need?

The A9 for the Sports Pro Markets..

Its not for me.. all of it.

Sane cameras for real world challenges please.

@CaPi
You do understand when the new model rolls out the previous one(s) drop in price? Providing products for multiple levels of budget & features?

linzdoctor7d: Something tells me A-mount won't be included!

@Trundling
Given the article picture from Manfrotto shows a Sony A9, I think E-mount is a given.

cosinaphile: still, the investors who paid for the r and d and paid heartily for the privilege of owning this are still screwed .... if there was justice then the money the equity firm paid would be made public and would be used to give panono backers their products at production cost

I'm glad this was saved but sorry for the backers who were screwed .... the sale should have been structured to put the full force of fulfilment as the highest priority .. as it stands its just a slightly convoluted instance of the ongoing corporate theft poisoning, ....well ....everything

and leaving the small guy screwed to serve the interests of the powerful

"well those sponsors invested their money"

No, they gave it away. And bankruptcy of the company means the possibility of getting a cheap, first round release of the product, the only return they ever might possibly see, went poof! For those angry that this is what crowdfunding means, welcome to the real world.

The only possible reason for Professional360 to honor those early crowdfunders isn't some vague "moral obligation" or "justice". It's positive PR.

On article Sony a9 Full Review: Mirrorless Redefined (2754 comments in total)
In reply to:

K1000usr: My ignorance shows here, but why are these mirror-less cameras beholden to such huge lens designs .!?

The bodies are shrinking, since there is no mirror involved. But look at this lens shown above in the title page. (Yes, it is a zoom lens, and some lenses shall be big/huge..)

Is this a reason why Olympus will still keep on shining? (Sony has impressive performance specs, no doubt. The camera looks compact, and really solid. I would want to own it. But only if its combination with a 24-70mm zoom is less voluminous than my K-1 with Pentax 24-70mm!)

The bottom line is lens size is proportional to sensor size. If you are expecting significant reductions in lens sizes you need to move to cameras with smaller sensors. Removing the mirror from the camera is irrelevant to lens size.

stanic042: I wonder how long will I bang the Pentax K5IIs around :)

@ GEONYC
People have been predicting the end of Pentax since forever. Pentax has ALWAYS been using someone else's sensor - be it Samsung, Sony, or film. I really don't think Sony had anything to do with the sale of Pentax by Hoya to Ricoh. Hoya had stripped out of Pentax what they wanted - medical imaging - and Ricoh was eager for an established point of entry into the DSLR market. They both got what they wanted.

If it makes you feel any better, I'm still using a K-01.
But given I also shoot video - with a GH4 - the K-01 is probably my last Pentax.

In reply to:

sibuzaru: see, if they used USB-C 3.1 it wouldn't need a dummy battery to connect to the camera

+FLruckas
Agreed. I think whoever came up with micro-HDMI should be shot. I have it on my GH4 and hate it - it's so tiny, fiddly, and fragile. mini-HDMI was much, much better.

In reply to:

Pritzl: I don't get it. Don't we buy mirrorless cameras to save on size/weight? How is lugging that lump along a good solution? I'm disappointed by the slow pace of development in battery technology.

Battery technology development has pretty much ALWAYS been slow. Big changes usually involve different materials. I would not look for this to change anytime soon.

In reply to:

Polytropia: To all the haters:

My grandfather shot Kodachrome Super 8 & also black and white movies of his kids. Those movies look as good today as they did when they were shot.

How good will all your digital videos look in 65 years from now? Will they even exist?

I can shoot some film and put it in an archival box with a projector, and know it will be viewable in 100 years as long as there is a source of electricity. I'm not sure you can say the same thing about any digital information formats.

And honestly how much more often do you really want to watch such videos? lol.

Also, protip: clouds evaporate.

Protip: Good luck buying ANY variety of Kodachrome and getting it developed.
