EOS Bodies / Re: 5Diii vs 7Dii (FF vs APS-C)
« on: October 28, 2011, 01:34:17 PM »
As Flake stated, people are interested in the 5DIII in part because it's been a while since the 5DII came out.  The assumption that a 5DII replacement will have '7D build, AF and speed' is unwarranted, because Canon will need to differentiate the 5DIII from the 1D X on features to justify the price difference of ~$4K (or they'll minimize the price gap and charge $4K for the 5DIII but I really don't see that happeneing).  So, people won't get their 'dream camera'.

I'm sure that Canon will want to find some way of differentiating between the 1D X and a future 5D MkIII, but hobbling the build an AF is likely to lead to trouble.  I think that current 5D MkII owners are more than a bit annoyed with Canon that there have now been a succession of much cheaper cameras with better AF systems.  In addition, the 5D MkII is not regarded overly well in terms of weather resistance compared with say, the D700 (not so great for a "landscape camera").  A 5D MkIII will be up against a D800 and I think that quite a few 5D MkII owners and potential upgraders, will be reconsidering their brand choice if the 5D MkIII fails to address some of its predecessor's weaknesses.

This weekend I joined an 2 days lasting workshop for motorsportphotography. The "hardware" was one of the hot topics there. The workshop was sponsored by canon and nikon. We could test some of the better lenses for sportsphotography including the camerabodys. It was very interresting. 
In the Canon-Group the tutors from Canon were not really able to highlight their new !-Dx product for sportsphotography for normal users. They recommend the usage of this camera with an fix focal lenght lens without an converter/extender! They did not see a reason to extend the AF working at an max f=8 even at another coming camerabody. "Buy an better lens... If you can buy this body, buy an 4.0 L lens with 500 to 600mm..." was the answer :o
Almost all visitors shook their heads.
The Nikonians laughed when they heard this. Nikon was presentig themselves as a corporation that is more and more looking to become an specialist for sports- and wildlife photography.

Sorry, I didn't realise that the D3 series actual had f/8 AF sensors? If Nikon fit an f/8 capable AF system to the D4, then maybe this argument will hold water.  I seem to remember that Nikon did the same sort of thing to their users when they made the D3 full frame, having claimed for years that DX was the new 35mm. 

The problem with the 1DX is that Canon have not release (nor breifed their own representatives of) a definitive explanation as to why they dropped the f/8 capability.  This has lead to speculation as to whether there was a geniune technical reason (i.e. a trade off), or whether it is just Canon being mean and trying to sell 1D Mk4 upgraders longer lenses.  Personally, I believe it is more likely to be the former reason; the f/8 focusing capability was a great marketing feature over the Nikon pro bodies and I can't see that they'd drop it when everything else about this camera seems to be focused upon topping the D3s.

The RAW format is a lossless compressed format.
The file size gets higher at higher ISOs because there is less to compress (due to higher nosise).

No, it's because CR2 format doesn't use adaptive Huffman, but predefined tables that are optimized for common case value distribution.

If adaptive Huffman or arithmetic coding (like h.264 CABAC) was used, high ISO raw images would be significantly smaller. Unfortunately, processing cost in terms of power consumption and silicon area needed would likely be higher, especially with more complex coding schemes.

Maybe future RAW formats will have PNG or lossless JPEG style spatial predictor functions. Combine that with adaptive arithmetic coding, and file size savings would likely be significant, even halved.

But may that doesn't really make sense - file size is not really a big issue anymore. Current scheme is very reliable - flip one bit in current CR2 format, and you can recover rest of the image with just one pixel error given software that can resync to Huffman stream. More complex coding could mean larger blocks of the image become corrupted without sophisticated error recovery and correction. Otherwise one bit flip could render whole image unusable.

Besides, if file size was really an issue, Canon would probably stop embedding a thumbnail AND a full size JPEG image in every RAW file! I prefer reliability over file size any day or night.

So much for "Demystifying the EOS 1DX Sensor", all this techno-babble has me even more mystified! Hopefully when someone gets hold of the actual camera we'll see some real life tests that show us what it can offer to photographers in practice...

Stop me if I'm sounding really cynical here, but Canon have stated that the new 1DX replaces both the 1D Mk4 and 1Ds Mk3.  Well it basically does, the resolution differences are negligable and every other specification appears to be an upgrade, so no more need for seperate 1-series bodies... Except there still seems to be demand for a full size high resolution DSLR; how much extra R&D costs would it take to put a (for example) 36MP sensor in a 1DX body and call it a 1DY (with perhaps 6fps).  That way you've suckered a whole load of people into buying the 1DX as a 1Ds Mk3 replacement and can also sell them a 1DY next year; voila, double the sales.  If they complain that the 1DX was meant to replace both the 1D and 1Ds series, Canon simply states "oh, but it did; this is an entirely new camera series". 

Like I said, stop me if I'm sounding too cynical...  ;)

On a different note:

1) No one spotted Frits van Eldik shooting the advertorial in Monaco then?

2) What the heck are the dual Digic 5s in the 1DX doing for their money? Pull me up for flawed logic if you know better:

1D Mk3 - 10fps x 10MP  = 50MP/second for each Digic 3
1D Mk4 - 10fps x 16MP  = 80MP/second for each Digic 4 (increase of 60%)
1DX      - 12fps x 18MP = 108MP/second for each Digic 5 (increase of 35%)

And the 1DX has a dedicated Digic 4 for AF and metering.  Pretty poor show for Digic 5 considering Canon have had three years to develop it (Moores Law anyone?).  I am missing something?

There are a lot of reasons for solid use of a 30+MP camera... As everyone I'm sure has read from me before, I'm a huge proponent for more MP, but with that being said, I also understand there's a place for every camera and every use... As i've mentioned before, in film days, a 35mm camera rarely was printed at anything bigger than 8x10... even at 8x10, with good old tri-x film (ISO 400), you could see some grain.  Sometimes you would be daring and ask your lab (or push it in the darkroom) and pump out 11x14's, but you knew you were going to lose quality... Professional photographers knew and had in their back pocket MF cameras or even large format cameras for bigger prints...

Now adays with cameras we can pump out 16x20 practically without any interpolation with the 5d/7d printing at 300dpi.  I have shot murals with my 7D that were put on tradeshow booths (20 feet wide) however they were still lifes and I was able to shoot the large scene in sections and stitch together to build a native file without any interpolation.  Larger MP's would mean that I could do that with less stitching and make things essentially quicker, better, higher profit margin, however I hope that we keep in mind the limitations of the 35mm format and if you have the rare need for super large images, not to expect a 35mm to pull that off but instead look at MF with digital backs or LF with digital/scanning backs instead.

Maybe thats whats guiding Canons tactics? with the 645D around MF is now not that much more(in price and size) than a top end 35mm body like the IDs so is there going to be much of a market? Focusing on a 5D sized body seems like a maximses the advanatges of 35mm, cheaper(even a higher spec body) and smaller than MF.

I think that these comments hit the nail on the head.  The 5D Mk2 killed off a lot of the amateur interest in the 1Ds line and affordable MF systems were putting increasing pressure on it from the professional point of view; Canon has reverted to the film era 1-series target audience with the 1 DX.  I think that more MP will come with a 5D Mk2 replacement (which I would no longer bank on being called the 5D Mk3), targeted at the high end amateur market and those professionals that need a light-weight, high resolution solution.

Well done Craig for sticking your neck out on calling this one... The rumour mill was incredibly quiet other than CR.  Last night I was starting to think that this wouldn't happen today, Doubting Thomas that I am!!!

Tomorrow morning at 4.00 GMT the announcement. No merging between 1D-1Ds.

I'm struggling to see anything being released at all, let alone being able to predict 0400GMT. It's been seriously quiet over the last few days compared to before the 1D Mk4 was released.  Still, there are some people on this forum who seem to have re-written Canon's entire lineup based upon this rumour. 

I hope for Craig's sake that something is released, otherwise he might face lynch mobs now that he's revealed his true identity; I guess that's why superheroes are always so coy (apart from Superman, for whom a pair of NHS specs and not wearing his undies over his trousers seems to suffice).

Also, what is with people on this forum? My karma keeps going down. I have never flamed a single member of this board.

I'm unsure just how this karma is meant to work; I think that one's profile should show how many times you have applauded/smote someone (though perhaps not whom), so that everyone can see if a person just a malicious little troll.  If all you're doing is smiting people, then perhaps further action should be taken.  It seems that you can only applaud/smite someone once every two hours (cool off period?!).  FWIW I have applauded you so that you don't feel so bad about all the smites you've been receiving recently!

I've just been reviewing the old 1D Mk4 & 7D rumours in the weeks prior to their announcements.  It is surprising just how much rubbish was sent to CR quite late in the day, as well as how many "nearly-but-not-quite" spec lists with a couple of key details wrong (was this deliberate misinformation from Canon, or simply "me too" attention seekers?).  There were also quite a few spot on sources (lenses in particular), but I remember that at the time, it was difficult to pick these from the background noise.  The 1D Mk4 was released on 19th October 2009, the day before Canon celebrated 50 years of SLRs.  Coincidence? We'll find out on Tuesday..

It's strange, over on NR there are a lot of people moaning that 36MP is too many.  Therefore if 18MP is too few, should we assume that 27MP is the oprimum point?!

Where are the CR2 & CR3 sources? There have been some dates announced and lots of CR1 rumors, but it seems to be a bit like convicting someone on circumstancial evidence.  Normally, we'd have something more substantial by now; I'm not saying that there will be no announcement on Tuesday, just that it isn't following the pattern that we've seen before (hopefully some leaked pictures/publicity materials will appear soon). 

If the spec list that CR has posted is true, then it seems to be a 1D Mk5, not a 1Ds Mk4.  I can see Canon wanting to capitalise on the coming Olympics, but the 1Ds Mk3 is very long in the tooth.  I hear the speculation that Canon might do away with the 1Ds line since the 5D Mk2 stole a lot of its sales, but I can't see that Canon would want to lose the premium price point by making a future 5D Mk3 the top high resolution body. 

If this is a 1 series announcement, it will be interesting to see the reaction if Nikon releases its prosumer targeted D800 at around the same time, as NR predicts.  I guess we'll know in a couple of weeks...

It wouldn't surprise me if there are no FF anouncements this year as there isn't exactly a lot of competition in respect of new models from Nikon or Sony.  There's also not a lot of spare wealth going around at the moment. 

This will mean that 2012 would be a busy year for Canon as people will be expecting two new FF cameras, a new Rebel and a mirrorless system; on top of that the 7D and 60D will be getting close to the end of their product cycle...

honest i think all this "too late" talk is nonsense.

it dosn´t matter that much.
the product matters.

Maybe your right, Canon hasn't got to its current market leading position by being first, but by making the right choices at the right time.  My feeling remains that the technologies for making CSCs a success are beginning to coverge; Sony has their new EVF, Nikon has some form of phase detect AF on sensor, Panasonic and Olympus are starting to get into their stride with capable yet compact lenses.  At the moment, no one has everything so perhaps it is Canon that can get the right mix, as they did with EOS.   

One thing that they can't afford to do is leave it too long, like Olympus did with AF, there are a lot of the 'enthusiat-wanting-smaller-second-system' crowd that have already given up waiting for Canikon and invested in either m4/3rds or NEX/NX.  Once they have a lens collection, it will be a difficult sell to get them to switch.  I'm pretty sure that when (and it's now almost certainly when and not if) Canon launch a CSC, they will go for it full throttle.  The only thing that worries me is where this will leave the current EOS system (especially APS-C) because there are still many lenses missing or in need of updates.
