Better to compare the Sigma 150-600 contemporary lens with the Tamron 150-600.

Also, what's wrong with soft edges/corners?

Plenty of Canon lenses are like this and people defend them to the death here! ;)

The growth in mirrorless shipments rose, the growth in DSLR shipments shrank.

"the design priority of these cameras was to produce the highest possible stills resolution, therefore some video functions were sacrificed. "

It's not in Canon's or Nikon's interest for them to have directly comparable products.

There is NO WAY that Canon will decrease megapixel count. Megapixels can only go up, never down as that is difficult for marketing to overcome. They could only go down by creating a new camera on a different line for a special purpose. Otherwise, for MP to go down, the specs would have to be incredible. 1DX type specs. Canon isn't going to hand down the 1DX sensor and shutter to the 5D line. I don't remember a 2nd tier pro camera inheriting the previous generation flagship specs. The flagship models keep certain strengths for longer.

You mean like the a7s? Did that camera not make waves, even though its pixel count was way down over the original a7 cameras?

The A7S is a new line of camera. It isn't a successor to the A7 or A7R.

Although Canon did move from 21MP (1DsIII) to 18MP (1DX). So yes, maybe this is a 5DX that uses the 1DX's sensor?

Would have to be a completely new sensor design and manufacturing plant for it to have massive new DR. Maybe that will be Sony's involvement?

Also, no mention of DPAF...

5Ds, 5DsR, 5DX, 5DIII, 5DIV....

Canon needs to come up with a new way to name its models!

I've been thinking that I need to get in the habit of deleting more of what I take and posters here have given me more courage to do so. Thanks :)

I just hope the library management is more robust.

I far prefer LRs edits / processing over Aperture, but every photo winds up in Aperture for me anyways because it handles library management far better IMO.

Can you be specific?

The only think I can think he means is that Aperture has a managed database option. Personally, that's not for me, if for no better reason than it doesn't work well with my backup strategy. For the short time I used Aperture, I managed the files myself in folders rather than allowing it to shove everything into a single amorphous blob.

The managed database is a big part of it, as is Apple's excellent Vault system for backups.  I also far prefer how the keywording, folders projects, and smart albums function in Aperture. 

I find that the amorphous blob for me is more organized than the multiple LR libraries I find myself creating to handle items from multiple jobs.  I can have multiple projects, folders, and ultimately jobs in the same Aperture library, whereas I find I can't separate jobs as well in LR.

I am excited by the new XXL pano option.  Maybe it'll replace gigapano for me!

The Lightroom ".lrcat" file is an SQLite3 database.

"237 Sold in 24 hours"

Not bad, selling ~10 5D Mark IIIs per hour.

"those who have nothing to hide have nothing to fear" :->

I'm going to invoke Godwin's Law of the Internet here, but if you said religion is not something to hide I'd show you WWII.

The problem is you don't know what it is that you may be persecuted for at some random point in the future.

At $1999, they're almost being given away.

I wonder what this is doing to their resale price?

Wouldn't catch me paying more than $1800 for one used now!

No surprise given that this is press.

There is quite a lot of history for Canon being a part of press photography so I would expect a substantial investment in lenses to be preserved.


Where might your cameras be going in the future? There’s nothing really new coming. We started with a few pixels and just keep adding more. We started with a sluggish processor and just keep making it faster. We’re really good at these “just make it a little ‘more than before' types of tasks.” Eventually we’ll have gigapixels and terahertz. Someone must need that.

Every pixel is converted to a 14-bit number, that whole chunk of data is read 14 times per second for the 1Dx, or five times per second for the 5Ds. The data throughput of the DIGIC chips MUST be able to handle the RAW PIXEL INPUT throughput, which is:
Canon 1D X: 19,000,000px * 14bit/px / 8bit/byte * 14fps = 465,500,000byte/s
5Ds: 53,000,000px * 14bit/px / 8bit/byte * 5fps = 463,750,000byte/s

The 14bits of data is stored in a 16bit word (or two bytes):
1DX: 507MiB/sec
5Ds: 505MiB/sec
