EOS Bodies / Re: What would be the time frame for the 5D Mark IV?
« on: February 18, 2015, 11:41:32 AM »
I am trying to buy a canon full frame camera. If i Find a Great deal on the 5DIII i will buy it ( great deal mean 1600 or lower). Should i just buy a 6D for around a thousand and wait for the 5D IV? when do you think it will come out and how much will it be? my guess is it would be $3499. Let me know what you think.

It depends on your needs. Do you need an action-capable camera? If so, the 5D3 is preferable to the 6D. If you don't need advanced subject tracking and a wide array of AF sensors, then the 6D is likely the better buy.

You're probably in the ballpark with the Mk4 price, though if they differentiate it enough from the studio models (e.g. if it has better video and substantially better AF, etc.), they may price it at or about the 5Ds level.

Nobody really knows.

If you just want to get into a full frame camera, the 6D is a great option, and will continue to be for some time.

Any info on whether there will be a new PV (process version)?

I'll be surprised if there isn't.

All I want and need is Lightroom. Stand alone, eternal license. One-time payment.

I seem to recall reading an Adobe person (though not an official spokesman AFAIK) stating that LR will continue to be offered in the retail/perpetual license flavor, at least for the next release cycle.

I do suspect that more and more software companies will adopt cloud-based recurring payment platforms, though, if for no better reason than to combat piracy. When the time comes that I have to subscribe, I will do so. Until then, retail please :)

Here's hoping:

*GPU-based hardware acceleration
*Improved noise reduction tools like those found in DXO's tools
*Improved masking options
*Strip out the bloatware they've added (books)

EOS Bodies / Re: Interview With Head of EOS 5Ds & EOS 5Ds R Development

So they ran out of room for the headphone jack?  It's not something I care about, but why did they use that huge double USB port???

You need the A/B connector for a device to act as a host (e.g. for the print button everyone uses).

I'm not certain the standard connector would fit any better. However, I don't suspect that top hole goes a long way towards keeping the door closed. Seems that they could have deleted the top one and added a headphone jack in its place.

5. Dual CF
Not enough space in the camera.

I don't think it would take much re-design to get dual CF slots in there. It would have to be only slightly thicker, I'd imagine, or if they made a change to the battery grip, they could probably move the slots forward and get away with the same thickness.



However I imagine they'll be re-using the majority of the 5D3 body, like with the S and R.

EOS Bodies / Re: DR from 5Ds will be 2 stop better then 7D mk II

I was reading Lloyd Chambers and he says that DR is identical to 5DmkIII?
http://diglloyd.com/blog/2015/20150206_1222-Canon5DS-dynamic-range.html

I tried to find his reference but it seems he hasn't tested it so the jury still out.

His reference is most likely Chuck Westfall's statement.

If they're using anything other than conduction to the chassis, which I doubt, heat pipes are the best bet. They're simple enough, and phase change is exceedingly effective.

It is definitely possible. There was a rumor...at least a year ago now?...that indicated Canon was working on some kind of active cooling. My guess is there is a fan or heat pipe of some kind in the camera body that moves heat away from the sensor, possibly releasing it along the body.

I hope they don't have a fan, as the venting would make for some pretty woeful weather sealing :P

EOS Bodies / Re: After a 50MP camera what is the next breakthrough?
« on: February 11, 2015, 03:26:19 PM »

Ah, if I can chose that at the time of taking the picture then great. And I get having the added flexibility. But doing that post-processing? Hmmm...

Tonemapping is part-and-parcel to image processing, whether the camera does it automatically (JPEG conversion), or whether a RAW editor does it (could be manual or automatic).

Focusing the viewer. The eye is naturally drawn to bright elements in a picture, so too much DR is not perhaps always a good thing. Having elements of the picture without too much detail means the eye ignores it and focuses on where you want them to....

In most images we view, we only see 5-10 stops (depending on medium). If you have 20 in the bag, you can creatively choose which to display. Start with more to end with less, since the opposite isn't possible.

On the topic of Dynamic Range --

If it does turn out that the 5DS has higher dynamic range - then this will be a major blow to the forum-reputation of all the sensor experts in here who have completely committed themselves to the claim the 5DS will not have higher dynamic range via their dozens of long technical essay posts. They will be completely discredited if the results show higher DR.
[snip]

Uh, naw. People are making predictions based on... well, no real technical data. Really, it's little more than marginally-informed guessing, and guessing wrong is no more shameful than guessing right is laudable.

I still think people are mincing words here. The 5D III does not have 14 stops of DR. The 5D III has 11 stops of DR. You cannot ignore the read noise, and people seem to be trying to do that with these funky explanations of why the 5Ds "has the same DR as the 5D III, but also has more DR than the 5D III". None of it makes sense.

It's possible (although not likely) they're discussing about two different things. The dynamic range of each pixel is related to its capacity versus noise, and the dynamic range of the output is limited by the bit-depth of the ADC and file structure.


Aye, I think that's mincing.

Perhaps. Or it's wishful thinking ;)

If Chuck was talking about overall digital architecture in stating that the S is equivalent to the 3 since they're both 14 bit platforms, but that the the other spokesman was talking about sensor level noise, perhaps the raw files will have better flexibility in the shadows while still being equivalent from an overarching perspective.

I doubt it, but might as well wish for the best.

Personally, I think whether 12-ish stops is "plenty" is entirely subjective and contextual. There are those of us who could use 16 stops, 20 stops, if we had it. In some contexts, 12 stops is woefully inadequate.


Subjectivity and feelings vs. objectivity and facts. I'm trying to stick to the latter. ;)

Sure. I left off the implied "for me". Most of my profitable shots have been well within 12-stops, and others I have been able to mitigate by traditional methods of balancing the scene. Within the confines of 14-bit RAW, 12 is generally speaking good enough for me. The situations where the additional range my A7R provides make a significant difference are few and far between. I agree that 16 or 20 would be wonderful, but that's a pipe dream in any near term still cam I'm afraid.

If I took a sensor like a Newton 920 with 94dB DR but ran it through an 12-bit ADC and store export 8-bit JPEGs, which would be the appropriate DR to quote?


The 5D line uses 14-bit ADCs and 14-bit files, and thus the output is bounded at 14-stops, for all 5D cameras.
The 5Ds sensors may have lower noise (and similar FWCs) to previous 5D cameras, and thus have greater flexibility to lift shadows. Again, I don't think it's likely, but whatever, 12-ish stops is generally plenty.

Jrista, why do you even shoot with Canon? You seem to bash them so much.

I think you're confusing jrista with dilbert. The former talks plainly about technology, the latter bashes.

What's wrong with the 5D III's dynamic range?

Just to get in on the laughable car analogy theme, the same thing that's wrong with the traction of a 4X4 when it's high centered.
