So if the 1DX were a True 1DS replacement with about 30-40MP then it would work out when cropping? I know you would end up with much larger raw files but that would work? Or maybe they could include a 1.3x crop mode with viewfinder masking or marks and correspondingly smaller raw file? Canon could have done that real easy I think.


It would work out IF, with 30-40 megapixels, the camera had the processing power to still shoot at 10-12 frames per second. With the processing power of the 1DX, a 30-40 megapixel camera would be down to 5 or 6 frames per second. That is the reason why those of us who are usually shooting in focal-length limited situations would prefer a 1.3 crop body with higher pixel density. If we would have to crop a full frame image, even if it started out with 30-40 megapixels, every time, we would be routinely throwing away a good percentage of the pixels, and we would be paying the price of a much slower frame rate and a shallower buffer. .

The 5D Mark III is a good example of this phenomenon. If you cropped a 5D Mark III image down to the same field of view as that from a 1D Mark IV taken with the same lens from the same distance, the cropped 5D Mark III image would have about 13 1/2 megapixels remaining. While the difference between the 16 megapixels of the uncropped 1D Mark IV image and the 13 1/2 megapixels from the cropped 5D Mark III image is noticeable, it is not a major difference, but the price that you would be paying for the 5D Mark III pixels that you are cropping away would be slower frame rate and a shallower buffer. The processor on the 5D Mark III would be able to put out, for example, 9 or 10 frames per second if it only had to process the 13 1/2 megapixels that are left after cropping.

The APS-H format is discontinued as far as I know. It no longer makes economical sense given the current yields of FF dies.

The current 1DX is not really optimized for applications that require high spatial resolution such as wildlife/avian.

Just have to wait until Moore's law scales resolution and processing bandwidth for FF sensors. In a few years we'll sure see D800 resolution at 12 fps!!!

Pixie, you do have a 7D, right ? Now, plenty of "reach" there, right ?
So much so that I do not even see why you'd wanna have a 500mm lens ?
Especially for your zoo garden "wildlife" photography, even a 200mm lens on 7D would suffice, I think.

Well, you can start with improved AF, 14fps, & ISO 204,000.

p.4 #8 · Will there ever be APS-H in a compact body?


i like this APSH thread, because i actually and exclusively use this sensor format. just some more thoughts:

as i wrote, i am really satisfied with with the last two APSH cameras and for the moment it is everything i use (sold my APSC gear and a 5D2). the only thing i miss is a bit more WA, for example using the 24L which becomes a 30mm equivalent FOV. and that is quite a big difference.

sensor format has become less important than before - when FF always was the one and only format for truly satisfying IQ.

to me, your question is less about FF and APSH, but about APSH and APSC. if Canon stopped APSH, then also because APSC-sensors just became good enough (look how they push the 7D). so what is the advantage of APSH regarding APSC ? well, you get more potential resolution and IQ and an interesting (for some lenses) 1.26 / 1.28 crop factor on EF lenses instead of the 1.6 crop factor.

regarding FF, APSH gives more reach, yes. but coming pro FF bodies will deliver 3x MP and birdies and wildlife freaks will be happy and not look back to APSH, because they get much more resolution. of course a kind of high end 7D2 APSC will be a cheaper option, but i bet a 3xmp FF pro body will be ultimatively interesting because of it's so interesting higher iso performance.

you are asking if a compact APSH camera is thinkable ?
if it's better than top APSC and close enough to top FF (while cheaper and lighter than FF) then yes.
but this segmet seems to be covered by the coming budget FF segment.

in the end i really continue to appreciate the raw IQ as the excellent jpeg output of the 1D4. that sensor in a handy body with the 1Dx AF ... yes, i would like it - a lot.

I wonder if there's any other photogs/videogs like me out there that enjoy using the 1D4 for photos/video but would love to see the 7D2/etc. have an APS-H sensor. Because:

- APS-H is, IMHO, the perfect balance between full-frame and APS-C for natural DOF in relation to light needed and aperture size.

- APS-H is also the perfect balance between having a little more reach yet very good high-ISO noise capabilities, blowing away the APS-C.

- Shooting with 5Ds is always great, but the amount of light needed to stop down for larger DOF can be annoying. I've got to essentially

That is precisely the question that many who often shoot in focal length-limited situations have asked themselves. While I have no doubt that the 1DX has improved AF and high ISO performance, it isn't like the 1D Mark IV doesn't have excellent AF or has shabby high ISO performance. And that is why many who do shoot in focal length-limited situations have decided to pass on the 1DX because, for their kind of shooting, the 1DX would be a step backward.

While the 7D is a nice camera the IQ of Canon's APS-C sensors is still not as good as their APS-H let alone FF. Given the new 650D sensor shows bascially zero improvement over the 600D/60D/7D sensor I don't expect any improvements for a 7D II if it remains in this format. APS-H would be an ideal upgrade for the 7D II along with 5D III AF and would be a nice replacement when the 1D IV stops production. I'm willing to give up some reach but not as much as you lose with 1D X.

the 1D series was not only interesting for it's crop factor, but also for it's lower price (new and used) compared to the 1Ds line - for those who want a fast and relatively light pro body for everything.
for the moment you only have the choice between the 5D3 and 1DX.

Not redundent at all, the 1D series were great, and I just picked up a well used 1DMk2 and the images are amazing, and there only 8Mp !
So a APS-H style sensor really wouldn't be that hard for Canon, and it would also be affordable, something the rest of us who can't afford over $3000 or $5000 !

Take it the other way. Could the 1DX processors with a 27MP sensor (1D4 FF equivalent) achieve 8-9 FPS? I don't know but it sounds like a better way to combine the two bodies and offer 1Ds owners a bump in MP and 1D4 owners a way to FF without losing there reach advantage. I have a feeling though that photojournalists would not much care for those file sizes. Which brings us back to that perfect balance that Canon had with two 1D models.

I am also sad to see the end of APS-H. For me a 1D with 20 odd MP and 10fps and super high ISO would be perfect. Then have a 1DxS with 30-40Mp for those that don't need the high FPS but want higher Megapixels.

It maybe that Canon just didn't sell enough 1DsIII. I bet they will announce a 1Dx2 in 2 years with 25Mps though.

If Canon had used the 1DX processor with a 27 MP sensor, they would have been able to get about 8 frames per second. I don't see any way that Canon was going to make the camera with fewer than the 10 fps of the 1D Mark IV, and I'm sure that it was also their goal to win or, at least, tie the spitting contest with Nikon and go up to 12 fps. Many of us, however, would have been happy with 8 fps and the pixel density of a 27 MP full frame camera. The other issue, however, with a 27 MP full frame camera would have been related to how long it would take to clear the buffer. Thus, Canon made significant compromises that don't meet the needs of either those who want a high pixel density camera or those who want lots of megapixels. There may be a time down the road when the needs of all can be met with a single body, but Canon jumped the gun in trying to consolidate the 2 1-series bodies because the technology needed for that one do-it-all body isn't there yet.

Aren't those two the same thing?

If they make an APS-H 7D2, I want a new lens like the Sigma 30/1.4 for that sensor size.

No they aren't. The 1DX has two more MP then the 1D4 yet has far less pixel density.

As ggreene points out, while a high pixel count camera could have high pixel density, that is not necessarily true. While the 5D Mark III has the most pixels of any DSLR that Canon makes, its pixel density is somewhat lower than that of the 1D Mark IV, and lower by a wide margin than that of the 7D. While the 1DX has what might be considered to be a moderately high pixel count, its pixel density is at about the same level at the 5 year old 1D Mark III.

Those whose shooting allows them to use the whole frame are generally going to be concerned with the total pixel count. Those whose shooting is often focal length-limited and who are going to have to crop substantially on a regular base are more likely to be concerned about pixel density.

But it will always be much dearer than the APS-H version. It was hard enough to justify the $$ for the 1D IV let alone another $2K for a 1D X. If they priced a FF 1 series with 30MP, 10fps at $5K it would be far more compelling. We know that will never happen, so I'll take a much cheaper crop version: 18MP APS-H is 30MP FF equivalent, so that would do me fine and would still handle 12fps+.

There is one other factor that is often overlooked when discussing the advantages of an APS-H camera with higher pixel density over a FF camera with lower pixel density in focal length-limited situations. I've seen some, including earlier in this thread, tout the advantages of the 1DX over the 1D Mark IV with regard to noise at higher ISO. However, when you crop, you are magnifying any imperfections, including noise, in the image. Thus, if you are shooting regularly in focal length-limited situations and if you were were going to have to routinely severely crop the images from a 1DX, you would be essentially throwing away any marginal noise advantages that the 1DX would otherwise have if you had not needed to do the cropping.
