I'll superglue the video switch in the off position!

Good one! I am a stills only photographer. An 1Dx wouldn't match with my budget, but this one here looks promising...

I missed this a few weeks ago, but over at Northlight, they posted that there would be an EOS 5D C instead of a direct EOS-1D C replacement. This is said to be due to lack of sales for the $12,000 (at launch) cinema DSLR.</p>
<p><strong>From Northlight</strong></p>
<blockquote><p>we’re told that the ‘general purpose’ 5D4 will come along with 5D C specialist video DSLR. 1D C sales have not been good enough to get the return on development of a new version.</p></blockquote>
<p>That idea may shed some light on <a href="http://www.canonrumors.com/2015/02/possible-canon-eos-5d-mark-iv-spec-talk-cr2/" target="_blank">what we posted yesterday in regards to a test camera that shoots 4K in a 5D sized body</a>. I’ll say again, the source stressed that such a camera may not appear as a consumer product, just that it has been tested.</p>
<p>We will note that Canon has said themselves that they’re going to make more focused products in the DSLR space, and not worry about pleasing everyone with every camera.</p>

If the rumored 5DC is somewhere near the 3.6k USD price tag, I could opt for such a high ISO monster instead of a direct 5D3 follow up body. As I do mostly astro and low light it seems to be the right thing. I am looking forward to do moonlight event photography at astounishingly ISO 51k! Tried it out on a 5D3 using the nifty fifty F/ 1.4 wide open...well, it was still a tad too noisy ;-) But I will revisit my photographs and look what LR can do with them... Bring it on Canon. Three years down the road, I might be in the game for such a beauty ;-) !!!

If Canon really come out with an 18 MP low light version of their next 5D I could be in the market for one in a few years. Till then, my 5D3 rocks...

What will become of the 5D Mark III?  It will remain an excellent camera capable of delivering terrific images.

I've been searching about MCS tech, and wow... it's quite a step ahead...!
Panasonic in FEb 2013:


As I do not now much about this materia, did Canon mention anything in the past two years? Are they working on it, or is it panasonic tech achievement only?

So, given that Canon might be developing a similar product, how long is the wait for the next revoluationary EOS Camera then, which will mention MCS in its sensor specs...? Is there hope for an outing within the next 4 years?

uh, and it was shortly discussed here...now I got a new abreviation to jump at in camera fora ;-)

The most intresting statement is this one here:

Can this technology be implemented right away?

Yes, says Panasonic. The “micro color splitters” can replace all color filters in current sensors and they support both CCD and CMOS sensors. Furthermore, the new sensors can be manufactured using conventional semiconductor techniques and cheap, inorganic materials.

This is what I'd like to see from Canon's upgrades:

5D-IV - Wedding/Events/Sports/Wildlife/HD-Video (Target price $3,500)
20.2 Megapixels (5502 x 3668)
Native ISO range: 64-51,200
Expanded ISO range: 32-204,800
10fps (200,000 actuations)
71pt AF (all cross-type)
15pt active with max aperture of f/8

This looks intresting. "Native" ISO 51k, Yes Sir. This would give us some very nice ISO 25k.

That is a misunderstanding. Any camera can be updated to support "native" ISO's higher than their predecessor's maximums. That actually has nothing to do with IQ, though. It's just a configurable setting, that's all. The sensor would actually have to gather more light to make the prior "highest" setting better. Cameras are already at 60% Q.E. At best, we'll be able to get 40% more, but it is unlikely we'll see much more than 80-90% with consumer-grade sensors. That means we can get reasonably expect 20% more Q.E. over what we have now...quite some time down the road off into the future (Canon was improving Q.E. by 2-3% per generation for a long time there.)

I could see Canon going to 64% Q.E. tops with the next generation, although I kind of doubt it will be that high...it'll probably stay around 59-60%. If Canon starts strengthening the CFA again, that will reduce EQE, which will affect the total amount of light reaching the photodiode. IQE may reamain the same or higher...but it'll still be working with less light...so in the grand scheme of things, we could see WORSE ISO 25600 if the 5D IV got 51200.

Assuming Canon came right out with a 20% improvement over current Q.E. and the 5D IV hit with 80%, we still wouldn't see a factor-of-two reduction in noise at ISO 25600. We would see about a 25% improvement at best...and that is barely going to be noticeable under scrutinization.

Increases in maximum selectable ISO don't really have any bearing on whether that actually means less noise. Increases in Q.E. can mean improvements in noise...however there is both IQE (Internal Q.E.) an EQE (External Q.E.) The measurements we usually see give us IQE, which is just the conversion rate of photons incident on the photodiode. An increase in IQE paired with a reduction in EQE can result in worse overall performance. If we see increases in both EQE and IQE, or an increase in EQE at the same IQE, then we can see real improvements.

A truly significant increase in EQE could be made by ditching color filters entirely and moving to an MCS design, where we simply split the light via certain diffraction effects, but gather 100% of it. That kind of technology already exists...it would just need to be employed.

Thank you, jrista, for taking your time to explain this technical aspect to me. Lacking any technical knowledge in the aforementioned area, board members like you really contribute a lot to the better understanding of folk like me. Let's hope that Canon will start soon to walk that road as outlined in your reply.

They are saying all the words I want to hear.  That could be a worthy successor to the 5DIII.  Now, they just have to make it so. 

24-28 MP
Cleaner low ISO noise
Whatever benefit they can get out of higher ISO
8 fps

A most modest increase  in MP would be 24 MP for me.

I am not interested in a 50+ Mp camera. But any news = good news because it means something is going on.

So I guess no more than a year for 5DMkIV (similar Mp, higher DR, less Low and High ISO noise, just hoping... )

Now the new lens is interesting...

Plus one on that, although my 5DIII still rocks. Hope Canon remain with more or less the same MP count plus innovative sensor tech noise wise. I will keep to the 5DIII for quite some time anyway, but it will be good to know about any improvements high ISO IQ wise.

Lenses / Re: POLL: Which of these UWA options would you buy?
« on: January 25, 2015, 01:11:08 PM »
I have the 16-35 F/2.8 USM II

An 11-24 F/4.0 would be a nice lens, but Canon are asking way too much for a hobbyist like me. But, maybe sometime down the road a third party manufacturer like Sigma or Tamron comes up with a similar product, I mean a 12-24 update from Sigma with a permanent aperture like F/4.0 would be great. Or as Tamron just announced the 15-30 F/2.8, who knows what they have in their sleeve next...;-)

Just wonder, what they will do next, after the Canon 11-24 F/4.0 infos have leaked...Could they do an 11-24 at half of the Canon price?

Well, great news, but a big price tag for me as a purely hobbyist photographer. So, in the long run, the Sigma 12-24 F/4.5-5.6 will do. I'll go this route. As I only work at the low end, the additional .5 in aperture won't hurt that much. But the price tag is about 4 times lower, so this gives flight ticket money for a very nice trip or a low price fall vacaction along with my wife AND the siggy...;-)

EOS Bodies / Re: Canon Confirms Development of High Megapixel Camera
« on: December 31, 2014, 05:08:49 AM »
It makes no sense to replace the 5D3 with 52 MP body based on the 7D2 sensor. 

I would take the speculation that this will be a 5DIV with a massive dose of salt.

Going back to the original interview, Canon understands that there are two primary markets: Those who need high ISO sensitivity with excellent noise control (which Canon nailed with the current generation of full frame cameras) and those who want higher resolution (which Canon apparently did not feel was a sufficiently large market to place an immediate emphasis on, but they apparently now feel they need to compete in that market)

I am certain that the high resolution Canon full frame (5D HD?) will not be a direct replacement for the 5D III. This "5D HD" (high definition) may surface in 2015, with the 5D IV (or 5D High Sensitivity) version showing up sometime near the end of the year or more likely in 2016.

(As an aside: apparently the low ISO, high dynamic range market is such a small niche market that Canon doesn't see it as sufficiently large enough to warrant a major release at this time. However, I can certainly see a scenario where the 5D IV/High Sensitivity would see at least a modest boost in dynamic range)

I hope things will happen this way. But as mentioned here, maybe the 6DII will move up in the segment and kind of "replace" the 5Ds as the allround body, who knows. I hope it won't, or it would receive some enhanced features first. As my 5D3 is good for a few more years, it's the perfect gear for a thouroughly non commercial oriented amateur like me. I hardly sell some of my photographs. Enhanced low light capacity and IQ would be great by 2016, so there's time for savin' up or even skip the next body...happy new year to everyone!
