Lenses / Re: Introducing the Canon EF 100-400 f/4.5-5.6L IS II
« on: December 19, 2014, 11:06:35 AM »

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.

When does diffraction kick in on a 50mp 35mm sensor?! How would this be good for landscapes or studio shots where you stop down? Wouldn't scaling up a lower mp shot probably look the same?

Good read, thank you Mt. Spokane.  That's a level of nerdy I can cope with.

That site also has a nice intro to ND Grads section that I've used.

Can we agree the AA filter on current Canon sensors blurs the image on pixel level? Well that blur is perceptible when zoomed in at 100% when comparing the same shot, same lens different cameras (in my experiment a 6D vs A7R). This is not debatable. Shadow detail and DR (I called it colour rendition mistakenly) of the Sony sensor are clearly not the results of AA filter removal. Hope that clears it up.

My point was that I need resolution and sharpness on par with what the Sony A7r offers. If canon can deliver this in 2015, AA or no AA,  then that's what I'll be getting.

(This is the non-affiliated guy again)

Can we at least agree that we are using words to offer an opinion on an image-quality related metric?  How about some pictures to suss this out as a group?

D800 vs. D800E vs. D810 --> someone has to have this comparison. 

Other than Ken Rockwell.

Who did this.

Ken Rockwell did exactly this.

DON'T MAKE ME LINK KEN ROCKWELL!  There must be another way.  Find me other data, people.

I could easily see a 6D2 or 5D4 bundled with this lens going forward, particularly if Canon pushes video as a reason to buy future bodies.

I could see the 6D being kit with this new lens for sure.  But the 5D line is a huge bump in price, features, and expectations -- that brand will likely only be kit (by Canon) with an L zoom of fixed max aperture.

There are many articles about the AA filter out there, so it's use is no mystery.  It is there to reduce moire, but it's drawbacks are less detail, sharpness and lower resolution.  That is why the newer high MP cameras have no filter.  Put the AA filter back on, and you lose the advantages of the higher MP count.  Pretty simple really.

I'm sorry, but NO.

[Disclaimer to everyone:  I am not of an opinion on AA, so save the daggers for someone who is...  If you're a jerk, that is.  (Didn't mean to presume)]

Doesn't the Nikon D800 / D800E / D810 give us a canary in the mine to suss out how real / not real the upside of pulling the AA filter is?

I thought -- again, not well read on this -- that:

The D800 had an AA filter
The D800E 'bypassed' the AA filter but it was still there?  (Did I get that right?)
The D810 does not have an AA filter

Three sensors, all 36 MP, that take the same lenses on the same mount.  Has anyone stacked these up head to head to sort out what the real value is?  Did sharpness improve?  Did moire get worse?

What ahsanford said. I would LOVE to see a high-resolution, high-dynamic-range FF body for landscape shooting. I don't care about video, high stills frame rate, fancy autofocus. Right now I am very happy with my 6D, but would like the additional DR and resolution offered by the Nikon D810 sensor. Some of the MF MA film era legacy (literally) lenses I use would have to be upgraded, no doubt, but I am in the process of doing so anyway. AIS Nikkor 50 f/1.2 and 55 f/3.5 1:2 macro and 105 f/2.5 would become Sigma Art 50 and maybe the Canon 100 2.8L IS macro (I have and really like the 180 f/3.5L macro, but it is heavy on a long hike with a bag of other lenses).

Canon landscapers almost exclusively have an 'out' to get a D8_0 sensor without waiting or converting.  Since you don't need AF and can use Liveview, you can get an a7R, adapt your Canon glass to it with a fairly inexpensive adaptor ring and go to town.

No need to convert.  No need to wait.  Just $2200 will get you the IQ you want as a temporizing 'fix' until Canon delivers the sensor you need.  I've not done this myself, and I'm not calling it a perfect solution by any stretch, but others have tried this successfully.

You have made a good point about the 5DIII birthday.  I was surprised when Canon came up with the 7D2 without a significant sensor jump.  However with Lexar making their 2000X SD cards UH3, perhaps in the next year (or 2), Canon may feel that it is time to have a high MP sensor with dual processors to give a 6FPS rate.

Highly doubt you'll see much more than 4 FPS from any cameras wielding the next gen of high MP sensors in the near future.  The Sony rumor is a 46 MP sensor is coming, and their folks aren't expecting a high frame rate at first either.

I think the cadence would be:

2015 -- High MP FF rig with modest frame rate, say 4 FPS
2016 -- Same sensor with a souped up processor / buffer / card throughput and (what) 6-8 fps?

The missing bit for me is what Canon will do with another FF rig due for an upgrade -- the 1DX.  It was supposed to be the merging of the studio 1Ds line and the sports/wildlife 1D4 line, and it was decent at that task.  I say decent in that it's a stellar camera, but each camp had one hand behind it's back -- studio/landscape wanted more resolution and sports wanted APS-H reach.

But now, a new 50 MP FF rig cannot possibly push out anything near the 12-14 fps the 1DX can now (not at full res at least).  So Canon is stuck with a difficult choice here:

  • Split the 1DX back into its two camps and offer two new 1D bodies: one that is high res / low FPS for studio or landscape work and another with a different lower-res sensor that maintains a high burst for sports/wildlife
  • Only offer a studio/landscape high MP body and tell sports/wildlife guys to keep using their 1DX's (or possibly their 7D2's) until throughput improves down the road
  • Pull a 'sort-of-Nikon' and offer one body that is full res for studio/landscape but at the flick of a switch is a some-sort-of-crop high FPS beast.  APS-H fanboys can stop spooning with their 1D4's at night and move on with their lives.

All of those decisions have tradeoffs.  Not sure which is best.

I hope it's a full frame.
FF is a must if I were considering this camera. I couldn't image getting decent performance from 50MP squeezed onto an APS-C sized sensor. Larger than FF would be a very welcomed surprise that would have me crying with tears of joy.

I hate to throw the gauntlet down, but I think it has to be FF.  APS-C just got their once-every-five-years flagship, and now FF (typically a 3-4 year cycle according to Northlight's timelines) gets it's turn.

MF would be stellar but Canon is choking at supporting so many mounts today as it is, and MF means a new mount and new glass, right?

And if a new mount is going to happen, I'd bet the farm it would be for FF mirrorless and not for MF.  The FF market is so much larger that I cannot see Canon letting the A7 brand run riot unopposed for much longer.

But I still don't think Canon has launched a mirrorless system until they give us a @#$%ing EVF and more than two native lenses to choose from at B&H.   The embarrassment of the EOS-M is not the product so much as Canon pushing a ship in flames out of port with a vague intention to 'put that fire out soon'.

That 22mm pancake is one hell of a lens of the two we get to choose from.

I'll edit your sentence above.   ::)  I stand behind the original argument.

I agree with you completely (it's a great lens), but that's like enjoying your new car... that doesn't have brakes or any gears above second.  EOS-M is super-high IQ point and shoot that happens to have a removable lens mount for some reason.  But until the EVF and native EF-M glass comes forward, it's DOA competitively as a standalone system.

Errr... of the four EF-M lenses we get to choose from...  (11-22, 18-55, 22, 55-200)

Not available where I live (in the US), at least not at B&H.  Only the 22 prime and 18-55 are available there.  I seem to recall Canon formally shooting itself in the foot by not offering some EF-M lenses stateside because we (figuratively) gave them the finger when EOS-M was released and we didn't buy that many of them.

Well for me... I have an SL1 on my belt, a 7D2 for sports/wildlife/BIF and a 5D3 for landscapes/portraits/low light and everything else.... not clear to me why I would buy a 50MP camera (just landscapes???)

Some of my buddies that shoot the Nikon have complained about their 36MP camera in that their Computer bogs down with so much info (think Raw file size) ... almost all have had to then go out and buy bigger/faster computers for PP and storage!  Something else to consider! :P

Everyone said that would happen when the D800 was announced and sure enough, it happened.  But people used it and said "this is worth getting a faster computer and a bigger hard drive."  Nikon of course now has the FrankeNikon 24 MP D750 which is being viewed as a pretty well put together FF rig without the burden of the huge files.  As inventory and obsolescence-insane having many non-gripped FF bodies is, it lets Nikon scratch some different userbases itches really hard -- one high resolution monster, one higher burst with a tilty/flippy screen, one more vanilla for cost, perhaps a nearly-dedicated video rig like the a7S someday, etc.

But back to your point -- I think if the sensor is worth it (interpret that as you will), people will cope and get the hardware they need to manage it.  I imagine this same discussion happened when Canon offered 21.1 MP bodies years ago, right?

No AA filter, dual, identical card slots please, and if it's aimed at the studio, articulating touch screen as well.

No AA filter = no sale.

Just curious how polarizing the AA filter is for the various camps.  I really don't understand it as a feature / value proposition.

AA filter = a positive for folks shooting video, right?  Something to do with moire?

No-AA filter = a positive for detail / sharpness / resolution junkies, right?  Landscapers and... macro folks, perhaps?

(The above is my terrible understanding of this presented as a skeleton for more knowledgable folks to beat up / rearrange for my betterment).
