As the second system I have a Leaf Aptus 75 digital back on a Linhof Techno digital view camera, most of my landscape photography is done with that system. It would have been deadly expensive unless I had bought almost everything second hand. I like the quality for landscape pictures I get out of my Canon too, but use the Linhof to get movements (shifts and tilts) on all focal lengths and it's an all-mechanical camera (shutter and all), using a loupe on a ground glass to focus. I like getting back to basics, but without having to mess around with film, it's really fun to work with.

Images get very sharp of course, the "large format" lens designs (only primes of course) are near distortion-free, have large image circles (for shifting) and very sharp, with the drawback that largest opening is only f/5.6 and there's huuuuuge vignetting on the wides so one needs center filters and correct for color cast. The same designs would not work for a hand-held DSLR.

The slower workflow has also made me more thoughtful about the pictures, so I get home with fewer but higher quality pictures which makes me spend less time at the computer, which is great. However now when getting used to the Linhof I also work in a similar way with the Canon when out doing landscape, so one does not necessarily need a slow camera to work slow ;).

If Canon releases such a high MP camera, then price will be one of the major factors accountable for its success. It does not look like an "upgrade" cam for 5DMKIII as it will appeal to a limited market (landscapes and studio shooters), so it will not be in any real direct competition with 5DMKIII.

Wait a second. I thought studio and landscape shooters represent the majority of the market, at least according to all the whiners on Canon Rumors :o

No, the majority of whiners on Canon Rumors just want Canon to deliver actual improvements rather than the "same old" that is marginally better than what was previous.

i.e. They don't want a sensor in a camera that is almost identical in characteristics to one that is already 3.5 years old, they want a sensor that measurably has less bad attributes and measurably more good attributes.

Yes the success of this camera will very much be about low ISO performance, since that is what high resolution photographers use. Will it have as good DR as D800 at ISO50/ISO100? If it is as "bad" as 5D mark 3 it will not be a MF killer.

I think Canon thinks this is a niche camera, primarily competing with medium format digital.

Anyone familiar with medium format digital prices know that this camera does not need to be cheap. I think it is smart of Canon to make it a true pro body (unlike the D800) since it will then be more attractive as a "MF killer".

Even with a high cost body you will need the best lenses which will not be cheap either. High resolution photography is not cheap, so I would not spare any expenses on the body.

The 40 megapixel Hasselblad H4D-40 is $16,000 body only, and it is one of the cheaper MFD systems.

A major part of the manufacturing cost is the sensor, large sensors are exponentially more expensive than smaller ones. With today's sensor manufacturing technology a full-frame camera cannot approach the price of an APS-C camera.

I've heard somewhere that 60% of an entry level full-frame camera manufacturing cost is the sensor, and for these even lower cost cameras it's probably more.

Bottom line -- if you want cheap don't go full-frame.

So, if the 3D is supposed to between the 5D and 1D series, that also means the price will be somewhere between $3500 and $6800.  If this is supposed to compete with the D800(E), then I think Canon seriously missed its price-point.

I think it shouldn't compete directly with the D800(E). Making a prosumer body for a camera that requires top-of-the-line pro lenses to make full use of the pixels is just strange, which is what Nikon has done. I think a high MP camera should be a pro body.

Shooting high MP to its full potential is not cheap, you need expensive tripods and/or expensive lighting, and expensive lenses. When you have to buy everything of the highest quality anyway, then the body should be that too I think.

"Industry leading ISO Performance" limited to 6400 native  :P

High MP cameras is not about high ISO performance, it is about high DR at base ISO. If your applications require high ISO they don't require high MP, and then there's 5Dmk3 and 1DX.

Maybe this is a response the the Nikon 800E but it certainly doesn't fill the advanced amateur hole in the Canon line up.  I can't afford this camera, can you?

I just got into digital medium format, and then everything about 35mm (except super telephoto lenses) looks like a bargain :-). I actually hope that the camera would aim to be a professional camera (pro body etc) to put some more pressure on the medium format market.

With a 46 megapixel camera one will have to use excellent glass to make full use of it, so even if the body is $5000 the lens cost will soon be higher. Therefore I don't think it makes much sense to make a low cost high megapixel body (that's one of the things I dislike about D800, it should have been a real full-sized pro body I think). An entry-level full-frame with less megapixels would be a better amateur offer.

Great!

I think it will be meaningless to release a big megapixel camera if they cannot compete with the D800 concerning low ISO DR, so it is nice that this rumor indicates that they can.

Canon is already great at higher ISOs, but I think a big megapixel camera will be used for "medium format"-like applications, like well-lit studio, landscape etc where you 99% of the time shoot at base ISO and therefore the customers will expect DR close to what D800 can perform. Without great DR it will not be the "medium format killer" like the D800 has become.

24
Don't forget that the DR advantage is there at base ISO, at higher ISOs there's not much of a difference. For wildlife I think the Canon *system* is a winner thanks to the excellent super-telephoto lenses and great teleconverters.

The D800 can compete with some medium format systems thanks to the resolution and excellent base ISO DR, this is very clear at MF forums where the D800 is discussed a lot, some have dropped out of MF and uses a D800E instead. The 5Dmk3 is not discussed at all - it is not an alternative to MF. For typical DSLR type of photography though the 5Dmk3 sensor is good enough so it is other things that people care about, like how it feels in the hand, ruggedness, autofocus performance, speed etc.

I have sold my 7D, but I will probably get a similar camera in the future. I'd love a "baby 1DX", high build quality, large enough body to match full-frame lenses (as the 7D) and an APS-C sensor with good ISO performance.

I'd like a ~12 megapixel sensor, suitable for hand-held use, but since Canon has mRaw and sRaw a little higher count would not hurt. Make it a well-built full-featured action camera for tele work and it will be truly great.

The (not-so-unlikely) scenario that instead 60D and 7D is merged into a 70D with lesser build quality and there really won't be any "pro" APS-C body in the future would be disappointing I think. I don't like the current trend among many manufacturers of packing great electronics into mediocre bodies.

How will your photos be displayed?

From my experience what gains the most from high resolution is not necessarily the largest prints, but those that are watched most critically.

Say a spread in a large high quality photo book, or a large fine art print hanging on the wall. It also makes a huge difference if the photo is a portrait, or if it is a scenic view of a detailed landscape. If it is a portrait people generally wants to see it from a distance, but if it is a detailed landscape people can step close to look at a subsection of the picture just to look at all amazing details.

For a high quality photo book it is best to keep at around 300 ppi. For a large fine art print 200 ppi is about the lowest you want to go if it should look reasonably sharp up close.

For very large prints you obviously have to compromise, and if you have to compromise 22 or 36 megapixels won't make that much of a difference, heck you might say like Ken Rockwell that 6 megapixels is enough for anything ;-)

The advantage of digital medium format has traditionally been higher dynamic range and higher resolution, the disadvantage - an astronomic cost, still many professionals pay what it costs to gain that little extra quality. Now the D800 provides medium-format-like DR (perhaps even better DR) and resolution at an attractive price. A 35mm camera that crosses over into medium format territory, I think it is truly fantastic. The D800 sets a new standard of what can be achieved with a 35mm digital system. Great for fine art, landscape and studio photographers. Wouldn't it be great if Canon had a similar offer?

In medium format circles the D800 is now discussed as a serious alternative/complement to expensive MF cameras. Canon 5D mark III isn't even discussed at all. It should be said that the MF community is quite small though, so for total market sales it is not too important. But if Nikon gets known as the 35mm digital that can do it all, and Canon is mainly for journalism, sports and wildlife, many more beginning photographers that don't know for sure what they will do will rather invest in Nikon.

EOS Bodies / Re: Next Canon step in the matter of their sensors
« on: April 24, 2012, 04:23:53 AM »
Canon sensor is surely "good enough". It's easy to forget that the 5Dmk3 sensor is not bad, it is the Sony Exmor sensor in the D800 that is exceptionally good, in a class of its own. No sensor except Sony Exmor show these properties, and it is not too many cameras that have it.

However, once you've seen that it is possible to have cleaner dark colors than we were used to, it is hard not to desire it.

It is not about the Canon sensor being so bad it ruins pictures. It doesn't. The older version I lenses did not ruin pictures either, but still sharper version II are introduced to set a new quality standard. Sony has now raised the bar concerning sensor image quality, and Canon is currently lagging behind and shows no sign of having the technology to respond. Sure thing I like to whine a bit about that :-).

I use one of the more stable Gitzo carbon tripod. If you want sharp long exposures or 100% sharp images in windy conditions you need to spend. In calm conditions and normal length exposures (shoot in live view to avoid mirror slap) a simpler tripod will do fine.

I put my tripod in the water and use it in rough conditions, the gear is made to be used. It is more a mental thing, if one has so expensive gear that it would be a financial disaster if something breaks (and there's no insurance) one will be too careful and miss shots. Then it is better to use cheaper gear or get a good insurance so one dares to take some risk. The gear itself handles rough conditions.

I use a 3-way geared head. Slow to work with (unusable to track things) but much easier to precisely compose a landscape shot. Since I shoot landscape I use that 90% of the time. I have a ball head too which I use if I need to track something, but I don't like it for landscape photography. If I would have only one head for all-around use that would be a ball head though.
