On Opinion: Did Sony just do the impossible? article (1045 comments in total)

Dimit: Uncompressed 14 bit raw ???
No thanks...no need for 100 MB files for something won't even notice in 90% of the cases..

Sony A580 a very old camera had 12 bit raw and scored 13.3 DR on dxomark, so your claim that 12 bit means exact 12 EV DR is plain false, along with rest of your arguments.

Rishi, yu are assuming that drop in AR7 DR is due to the camera going from 14 to 12 bit. That's pure assumption. You don't know what else is apping to read mechanism that is causing the DR drop.

Please stop speculating. Your friend Barney Britton claimed that you get 2EV with 14 bit, even though there is no proof that claim is true for even the best sensors.

As for medium format cameras, those sensors have so bad DR that even 11 bits is enough for those cameras, let alone 16 as someone assumed based on you guys claims.

steelhead3 , wrong. Most MF cameras have low DR (check Dxomark) and don't need more than 12 bits. 16 bits is pure marketing nonsense.

Barney Britton, no he doesn't. There is absolutely no evidence that going from 12 bit to 14 bit gives you 2EV more DR. That's a claim you made up with no proof. If we follow your logic, then going from 14 to to 21 bits will give you 7 more EV, and obviously that's a ridiculous claim.

In reply to:

Bervilat: Now, Canon, please make this sensor deliver 16 bit raw (just like the ones in medium format do) and stuck it into something a bit bigger than the EOS M (just enough to fit the larger sensor) and sell for 1000 dollars.

One can always dream, right?

Increasing bit depth doesn't increase image quality if the sensor is not up to task. It's actually waste of resources, slows down camera and achieves absolutely nothing

Operator: At least dpreview is honest enough to mark the article as "Featured Story". Sony must pay a lot for this advertisement.

But, makes perfect sense - in the moment they lose money with the mirrorless cameras. Let's see if A7r II will be a success (personally don't think so) ...

Thom Hgan is not a credible source. A few years ago he was claiming Soy is quitting with FF camera. The guy is just hot air.

Yes bur Rishi seem to claim 2EV difference for 14 bit raw which is complete nonense

The Straw Man: Cue the Canon haters and the FS7 price comparos. If you think $16,000 is overpriced, you're clearly not the target. This is going to be THE camera for news, reality TV, commercials, documentaries and low budget films - basically the categories the Cinema line currently dominates.

The C100/300 was/is a huge hit, the Mark II drops with 4k, new AF, better codec, 10-bit internal, more DR, more color settings and so on. Plus the lens ecosystem is far better than Sony. And you don't get the ugly Sony colors.

Looking forward to footage.

Bloom doesn't use AF at all and he said it repeatedly. Bloom also thinks FS7 is superior camera ..

From his twitter account

https://twitter.com/PhilipBloom/status/585674066843070464

" it doesnt equal. it doesnt even reach"

What Bloom is saying there is that C300 Mk II doesn't equal FS7 and doesn't even reach FS7

Dan Chung also owns FS7

Direct link | Posted on Apr 9, 2015 at 00:32 UTC

FS7 is not only half the price but does 4K at 60 fps. C300 only does 30 fps 4K

E-mount can not oly use all Canon lenses, but it can use speedbooster adapter, giving it full-frame look, something C300 cannot do due to the mount limitation.

FS7 can use not only Canon lenses, but also Nikon, and Leica M mount lenses, PL lenses, and native e-mount lenses, all at same time. The user isn't stuck to one mount.

C300 does 120 fps only in crop mode. FS7 does 180s fps in full sensor mode.

This is really no contest.

FS7 wins easy

By The Straw Man : "vastly superior AF. "

What AF? C300 cannot AF in video mode. And even if did, the pros don't use AF during videos.

FS7 can not only use all Canon lenses, but it can also use Canon lenses with speedbooster, giving it full-frame look. C300, due to mount used, cannot use speedbooster adapter.

Johannes Zander: For the moment Canon wins the megapixel race.
But surly Nikon, Sony and maybe Pentax with a new FF camera have a very competitive answer.
Anyway, 36mpix of my D800 are plenty for my amateur needs.

645Z is three times more expensive and has not even close to same lenses, AF as Canon and Nikon fullframes.

On Canon EOS-1D C sees $4000 price drop in North America article (249 comments in total)
In reply to:

Papi61: It probably cost Canon $1k to make, so they have lots of room to deflate the price. Personally, I wouldn't buy it if they sold it for $2k. And it's not because I'm a Nikon shooter, but because the Samsung NX1 is so much better at 4k filming.

1Dc weighs 1.5 KG and FS7 is 1.8 KG. That isn't that big difference.

ChuckTa , FS7 records 4K internally, 10 bit, instead of 8 bit, and 60p (instead of 30 on Canon) and can do 1080p slow motion up to 180 fps, ,XLR ports for proper audio, built in grip, peaking and other video related features (Slog3, zebra), has E-mount and costs about the same as discounted 1DC. It can also behave like FF (DoF and field of view) with speed-booster.

MASTERPPA, mirrorless cameras with shorter flange can adapt Canon lenses, easily, including electronic connection between camera and lens.

So infact, for video at least where AF might not be relevant, mirrorless cameras have far more lenses than Canon mount cameras.

Ergo607: What is flickr?

Your rambling is totally irrelevant. The post is about what kind of cameras are most popular on flickr, and given that flickr has millions of users, it's a relevant statistics about overall popularity of cameras.

Jogger: Sony A6000 looks best to me, esp. RAW and fine detail.

balios, these shots are taken at F5.6 .. all these lenses exceed sensor resolution at that step down aperture, so what you are saying is completely irrelevant.
