So far, I've avoided being bitten by the Zeiss lens bug.  Well...for my personal photography, at any rate.  I've bought ~$2MM in Zeiss research equipment (not my money, of course), of which close to ~$200K was for 'lenses' (microscope objectives).

I'd be glad to catch that bug, but those lenses are dead to me without AF. 

I'd consider an MF lens for 100% dedicated landscape work, but all they have are primes for EF, right? I strongly prefer UWA zooms for landscapes as you can't always move your feet.

He must have picked an excellent copy of the original 100-400 for his comparison.  I'd say my version 1 lens is average but the version II lens is excellent.  My copy of the new one is much sharper wide open plus the much improved IS and twist zoom is a "must upgrade" if you use this lens a lot.

They tested four copies of each generation 100-400, and averaged the numbers.

....that's way LR results are more reliable than other reviews where probably only one unit is tested.

Sure, but LR is sadly not a testing house.  They have world class equipment and a very bright soul to publish and interpret the results, but they are not in the business of comparing hamburger A to hamburger B.  Every time Roger publishes his data, he leaves out one lens we really want to compare against or an aperture other than wide open, etc.

To him, this is a curiosity that he dabbles in, but ultimately he's running a business.  So I have to use  PhotoZone and LensTip to compare numbers and TDP to see IQ with my own eyes.

Ah, but Neuro, doesn't having a super detail rig for studio (even if it's called 5D4 or 2D or whatever) and a 1DX Mark II beast for high fps outdoor work sort of split the goal of the unified 1DX anyway? 

Who's goal are you talking about?  If you mean the consumer goal of having 'one camera to rule them all' or something to that effect, then yes.  But Canon's goal is to make more profit...and the consumers' goals only matter insofar as they affect buying decisions.

Say they looked at their sales data and found few 1DIV owners with a second body also owned a 1DsIII, but many also owned a 5DII.  That would suggest a high MP non-1 body would be a more profitable path.

Neuro, I'm just pointing out Canon's quest for unifying the two 1D camps -- their big marketing message when they double tapped APS-H in the back of the head and released the 1DX -- rings a little hollow in light of what will probably happen after this high MP rig is announced.

Yup, the Zeiss 15mm accepts 95mm filter.

Hot damn, you're right! (see attached pic from TDP) I always assumed an integral hood at that FL meant no filtering.

So CPL and ND work with it but a slide-able ND grad would not for that lens. That's better than nothing, I guess.  But at 16mm on a 16-35 zoom -- I can go to town with more options and the chance to combine filters.

For the wildlife photographer the real benefit of the mark ii 100-400 will not be a huge iq boost (which does not appear to exist). The real news here is the improved IS, the much faster and more accurate AF, and hopefully an improved IQ/ performance when paired with a 1.4x.

So help me understand as I don't shoot long glass (I am happy topping out at 200 and don't shoot sports or wildlife)

100-400 f/4.5-5.6 zoom + 1.4x TC III --> 560mm f/8 for $2,648

200-400 + 1.4 integral TC ---> 560 f/5.6 for $11,799

That seems like a huge jump in price (and quality).  Wouldn't that inform Canon that there should be a 'nicer' equivalent 500-600mm option for a mid-level price point?  Perhaps a native 200-600 f/6.3 lens that didn't need a T/C?

I ask because Sigma's Sport 150-600 very well might be that lens -- $2k for a 600mm f/6.3 without T/C drawbacks.  Would prospective White Unicorn buyers opt for this lens instead?

I can certainly see the appeal of it, but as you mentioned already, from an Events PoV... Also, UWA videography has possibly just gotten a fricktonne more exciting for lots of folk!

But this lens is DOA for most landscape work -- no front filters plus an integral hood were terrible decisions.  Though, in fairness, those decisions may have been compulsory to get 15mm.  It seems 16-35s have the flatter front element figured out (and thus are loved by landscape folks), but 14- and 15- FF lenses have to be bulbous to work effectively.

I'm not aware of any 14- or 15- FF lenses that take front filters -- are there any?

Is it just me, or is Tamron about a year late with this?  Haven't many Canon UWA zoom folks (save perhaps the event folks) migrated to the excellent and somewhat fairly priced new 16-35 F/4L IS?

They desperately need to go up with megapixels, as even the cheapest model is 18Mpx. I hope they´ll go 24-32Mpx for APS-C and 40+Mpx for 5D class FF body.

That ship has sailed on APS-C.  The 7D2 is the last flagship APS-C rig you'll see for quite some time, so 20 MP is all we get. 

Besides the obvious "Only +2 MP over the 7D?" first blush response some folks had when the 7D2 spec list dropped, there is the longer term 'king of the Canon APS-C spec sheet' problem.  Though Canon's crop world will likely proliferate one of the two 20 MP APS-C sensors to the lower trimlines over the next 1-2 years, it might get weird when a T8i or 90D comes out with a 24 or 30 MP sensor and the 7D2 is still sitting at 20 MP.

So.... Am I oversimplifying this analysis if my take away here is that because the center number of the DO lens is now higher than that of the 100-400, the DO lens has leapfrogged the 100–400 and is now a better lens?  If so, in what exactly, sharpness?

Based on the quick comparison at LR, you could conclude that the old DO was not as sharp as the old 100-400 AND that the new DO is sharper than the new 100-400.  That's an interesting conclusion.

Shouldn't we expect that?  The DO lens is a slightly faster prime that costs 3-4x as much.  It ought to be sharper.

Wow.  Both are spectacular values.  I believe the 16-35 f/4L IS is now sold out, but FYI for future refurb discount deals.

You missed an option...don't release a high MP 1-series body.  The rumor here (CR3, so CRguy believes it's pretty accurate) indicates a non-1-series body for this release.  It seems likely to me that Canon will give a slight resolution bump to the 1D X successor (24 MP, perhaps) and keep the 12 fps. 

They unified the 1D and 1Ds lines for a reason.  While no doubt there are some who bought both, having a 1-series speed demon and a 5Ds/4D/whatever high MP body for studio/landscape may be a more viable option from a sales/marketing perspective.  It's one I'd personally consider (but then, I'd also consider a 1D X + 1D Xs combo  :) ).

Ah, but Neuro, doesn't having a super detail rig for studio (even if it's called 5D4 or 2D or whatever) and a 1DX Mark II beast for high fps outdoor work sort of split the goal of the unified 1DX anyway? 

Studio 1D shooters will presumably leave that trimline for the new high MP rig and outdoor/sports/wildlife guys with 1DX Mk II will wonder why the lines were fused in the first place!  Their precious APS-H will be dead and gone and they'll stuck with relatively reach-limited FF rig that mandates slightly longer supertele purchases.

These are just rough thoughts off the top of my head, but it would appear that with finite throughput possible, you kind of have to have two lines of top end cameras:  one for detail and one for speed.  Why the hell did they fuse those lines in the first place when that speed/detail relationship will always be true?

As for considering what the new high MP rig is, yes, if the rumor is true, it won't be gripped.  See my *other* sprawling post (page 12) and let me know which bucket you expect this new camera to be.  I'm curious!

Photozone has also posted their review:  http://www.photozone.de/canon_eos_ff/896-canon100400f4556is2

Photozone's data and LR's data are not similar.  PZ's Mark II (At least in resolution) was a marked improvement over the Mark I.

http://www.lensrentals.com/blog/2014/12/a-brief-400mm-comparison

A very brief IQ comparison is at the link above.  First they compare the 400 DO lenses, and then they report sharpness data for the white unicorns against its predecessor, but he only reported wide open data at 400mm.

More to come, hopefully, but it appears we'll be waiting for LensTip or Photozone to get the lens and do their thing.

Considering their current pricing: I estimate 4500-6000$.

Ah, price.  So much fun to speculate about.  The price will of-course heavily depend on where/how they brand it and what tech they put in it.  Assuming it's non-gripped as the story says...

The high res 6D2 sort of path
If the 50 MP camera is a stripped down FF body, i.e. functional (but not best in class) AF system with limited number of AF points, 3-4 fps burst, lots of design features and tech wholesale ported over from other bodies, etc.  Call it a '6D with a huge sensor' (or a 6D2), and it would be around $2,500-3,000 or so. 
My guess is:  no chance they will do this -- not with their first high MP rig.   Too many pros have screamed for high MP for too long, so to put it in a relatively simple FF body would be a let down I think.

The 5D4-ish path
If this 50 MP rig is branded the 5D4 and has that 'level' of feature set, options, robustness, etc. plus 1-2 recently newish things they always sneak in -- perhaps anti-flicker mode, intervalometer, automated focus-stacking, etc., then I think it will be in the $3,500-4000 neighborhood as originally posted on this site. 
My guess:  Whether it's branded 5D4 or not, a camera on this level this seems the logical first entry into the high MP game.

The all-battlefield workhorse path -- a 5D4 crossed with a 1D5, minus the grip
There's been some talk of a 50 MP rig with X fps with a built in crop mode that gets you 2-3X fps.  Think of it like an 'APS-H' switch that you can turn on/off.  As the crop + higher burst screams action and sports, such a rig would need to have a really high-end AF system, weathersealing and build quality. They certainly would get north of $4k for such a rig -- how much would seemingly depend on the burst rate. 
My guess:  There's 'too much new' going on at once here, so I don't see this happening.  Also, if Canon ever did this, surely it would be a 1D body, right?

The No-shadows-can-hide-from-this-sensor path
If this 50 MP rig has fundamentally better sensor tech and is that great game changing sensor that many have asked for, you brand it as something better/higher than 5D (4D or 2D, take your pick) and you charge fundamentally more for it.  This is the rig that would flip competitive business, so this could be a $4-5k non-gripped camera. 
My guess:  I have limited confidence that Canon has this in them given their sensors of late, so I'll call this one doubtful.

I give ranges on all the prices as it very well will depend on if Sony's 46 MP sensor is out there by the time Canon launches.

Some people are excited, some are denouncing this. One thing is for certain: this is a huge buzz that will not just affect Canon shooters but shake up the market for other brands as well. Studio/landscape shooters will be flocking to this 50MP body if all goes well, and suddenly Nikon and Sony will have to have something like this.

Sony (and by extension, Nikon) will likely beat Canon to market with a widely-rumored 46 MP sensor.  So I don't think people will flock to this solely because of resolution -- they'll flock to it if it breaks new ground in IQ.
