Wow, very interesting thread! I dont understand all of those technical terminologies here but I just love to see the world thru my mere 16 MP HassyCWD. It truly looks different from d3s or d700.
BTW the MV' s pics are awesome. Thank u for sharing.

Sitting here looking at my inspiring Alan Ross 8x10 print of an Ansel Adams original large format negative from 1952.

No, I don't think I'll participate in pounding nails in coffins of either large or medium format cameras anytime soon.

You can't really make an argument for MF from an 8x10 print...

The DOF is so narrow with MF I would rather not have any of my or family member's portrait taken with a MF camera. I actually prefer a background that is somewhat discernible as to tell a story and the "mood" of the environment one is in.

Granted you can push clean 60MP from medium formats, but how many actually need that many pixels other than pros in the fashion and advertising industry who need to print gigantic posters.

An 8x10 print? Sure ya can.
http://www.luminous-landscape.com/understanding-series/everything_matters__it_is_all_about_the_small_details.shtml

The dof is so narrow with MF? That really doesn't make much sense. The dof CAN be narrow but it doesn't have to be.

Need that many pixels? Nobody NEEDS a camera to begin with. Need is never the right word. By that logic no one needs a 22mp camera, a 12mp camera, a 6mp camera.... Having seen 40x50"+ prints from 8x10 film....the experience is on a completely different level than DSLR prints. It's not even close. Nose to the prints? Absolutely perfect. Standing arms length away it's like I am in the scene. I can see my 12mp D300s images break down at under 16x20. Areas of smooth tonality look noticeably worse. Would a customer care? Probably not. But I do. I don't want to see that. I don't want to have a 'minimum viewing distance'. My goal is absolute quality through and through. 6" to however far you want to stand away. A d3x doesn't compare either.
http://www.onlandscape.co.uk/2011/12/big-camera-comparison/

No one argues the efficiency of a DSLR and for a lot of people the prints, at any size, may be 'good enough'. But having seen 8x10 film prints and having made some myself there is just absolutely no comparison.

There is a sweet spot between depth of field and diffraction. Wouldn't medium format require a smaller apertures to achieve the same depth of field of 35mm? Wouldn't diffraction reduce advantages in resolution?

For MFD maybe but probably not, I certainly don't think it would negate the edge. Take the D800 sensor and make it MFD size and it will blow the D800 away. Look at the IQ180. Absolute resolution means only so much as well. The amount of enlargement from a DSLR size sensor is enormous.

Size matters when it comes to ultimate print quality. Starting with such a small original is a handicap that I don't see disappearing anytime soon.

With view cameras you can also use front tilts and a larger aperture if the scene allows it. Done smartly you can get a whole landscape in acceptable focus @f/16, barring any tall subjects in the fore/mid-ground. The incredibly small degree of enlargement with 8x10 film means the actual negative need not have incredibly high resolution. I've shot at f/90 and not noticed anything at all. Whereas f/22 on my D300s looks very soft.

Thanks. Mamiya 645 with the 80 1.9 wide open.

Back on the conversation, of course ALL formats are always pushing more megapixels and better image quality, but I'll take the largest sensor size (in digital please) that I can afford any day. Does anyone care to compare the latest and greatest 16 mp m4/3 camera against my 5 year old 12 mp D3?

While we're at it, my iPhone has just as much resolution as my old 1D2... Why are we still using DSLRs again? (insert sarcasm font)


I suspected 645 full frame and not cropped MF, and a very fast lens We would need 45 mm f/1.0 on 36x24 to do something similar, but the vignetting, aberrations and bokeh would be worse,

Yes, back on the conversation. I am with you in that I'll take the largest sensor size in digital that I can afford any day. But there will also be a great number who have a specific quality requirement, and want that to be met at the lowest possible price. As the quality improves, there is a migration in that group towards smaller formats.

As previously mentioned, it is also not a clean cut that a MF digital sensor will be superior to a 36 x 24 mm sensor . Smaller sensors will always have access to more efficient fab technologies, and as a generalization are less efficient per area than contemporary larger sensors. For noise, tonality and color sensitivity in equivalent images (same perspective, FoV, DoF, shutter speed) it is the efficiency per area that counts. MF sensors will always be inferior as soon as they are used above base ISO, becuase the smaller sensor has to be used at a lower ISO for equivalence.

For maximum image quality at base ISO, MF sensors are usually superior. But the Pentax 645D is particularly weak here because it only supports ISO 160. I predict that the D800E at ISO 100 and the Pentax 645D at ISO 160 image quality (lens issues aside) wil be impossible to tell apart. The Pentax 645D I regard as a contemporary sensor, only two years old and not replaced by anything newer in the same system.

few as in one of 3 people left still using anything from pentax?

pentax just makes me think Konica branded film, something obsolete that's great for a laugh when cleaning out the basement.

One aspect of this discussion is "What is dead?"

For instance, to compare with a different industry, many folks would consider records/vinyl as dead. However, it's not quite dead. And while I haven't been paying attention lately, at some point, I guess it may have actually been growing a bit. What seems to be dead are the successors to the CD. Multi-track (more than 2 channels) and far higher sound quality, but ... no one buys them. Why? Because frankly, 90% of the population seems to be happy with MP3, and consider CD's better than they need.

Is high end audio dead? No. It is still alive in the movie industry. And audiofiles still spend bucketloads (when they can), just like camera folks.

So, does "dead" mean that medium format cameras will never be mainstream? If so, then I would suppose you could argue that MF is dead. Just as vinyl is dead.

Similarly, 90% of people are happy with the photos their cell phone takes and break out the P&S for "high quality" photos. To them, MF was never alive.

Does that mean that there is no use for MF and large format? No. There are buyers. There are high end "art" photographers as mentioned above. There are quite a few reasons for very high end cameras.

I was going to add more, but I think that is most of what I was going to say, and I have to rush off and pick up a pizza.

MF dead? When your hard drives fail and your multiple digital image backups become obsolete and unreadable, my film photos will still be around. BAAHAHAHAHAHA . . .

What I was attempting to express was that some of the finest prints made today come from large and medium format cameras.

I like and appreciate new technology and am considering the purchase of a D800, but I have trouble understanding the need on the part of some to declare other photographic tools (such as medium format or large format or film) "dead" when you consider the wonderful art they (and their skilled users) continue to make.

Jan Brittenson, maybe you can answer a question that I have had kicking around in my head forever. For the same angle of view, larger formats use longer lenses. That means that at a given f/stop the physical size of the aperture will be larger on the larger format camera. That means, in turn, that the ratio of open aperture to circumference will increase for the larger format camera. Area goes up as a square factor while circumference goes up by a linear factor. That suggests to me that diffraction will be less for the larger camera at any given aperture. Am I wrong? Isn't that why you can get away with f/64 on a big camera, but not with a 35mm?

The biggest reason you can get away with it, from what I know, is because of the degree of enlargement. The perceived effects are so very little with 8x10 because you don't have to enlarge the negative in many cases much at all. 35mm requires a huge degree of enlargement.

It is correct that diffraction for two images from different formats enlarged to the same output size, only depends on the ratio of open aperture to circumference. So for a given f/stop the larger format will have less diffraction, even after enlargement. But it will also have less DoF, after enlargement. To equalize the DoF, you will end up with the same physical size of the aperture, and consequently the same diffraction.

Actually, diffraction is the same or less on the smaller camera, because you have more DoF at the same physical aperture, angle of view, and camera position. So you can shoot at a physically bigger aperture for the same DoF (as you'd judge in a comparable enlargement).

But even though you can shoot a smaller camera at a larger aperture and shorter focal length, you still lose the sensitivity race. (Sensitivity drops with the square of the size, while the DoF gain goes up linearly.)

That does not sound right.

These are taken from the same distance with 36x24 mm full frame 135 mm f/9 and 1.6 crop 85 mm f/5.6.
In both cases the angle of view is 18 degrees diagonal, and the physical aperture is 15 mm.

As you can see, for the same physical aperture, angle of view and camera position, the DoF is the same.

Hi Dr. Nguyen,

I don't really spend much time on places like this since I actually make a great living off of shooting both digital and film, more film lately too. I use digital for my commercial and editorial clients, film for my fine art and some of my editorial clients.

The main reason I have checked in as of late is that I have a D800 on order through NPS, looks like a great camera and will be a nice upgrade from my now very broken in but still flawless D700. But in the past four months, I have also taken delivery of over 500 rolls of medium format Kodak Ektar 100, Portra 400, Tri-X, TMX, Acros 100 films and literally hundreds of pounds of chemistry and Ilford paper...over 6K in inventory since November....

Now, if digital is all that you say it is...why do you think a professional photographer who has a D800 on order and has been using digital cameras full time for over 18 years would spend thousands on all of this "outdated" and not-as-good-as you say it is stuff mentioned above...?

I'll spare you the mental gymnastics and answer it for you:

I can just as easily if not *more* easily achieve a brilliant fine art print in the real darkroom compared to the light one with computers in it. I now make anywhere from 3x to 10X the income from a real darkroom print than I ever did from a Lightroom print, so do most other pros I know who make a living off of fine art. Now while digital or giclee printing is starting to be more accepted in the fine art world, what it is not doing is driving the price down on a real darkroom print...if it is a brilliant image.

I built up my Hasselblad system for a fraction of what it costs new and even less than the HD system. They do not require batteries and they do not require the machine we seem to do everything on these days, a computer. I use medium format film because I love the workflow, the journey, the fact I can put a partially shot 120 film back loaded with Infrared in two ziploc bags in my freezer and pull it out weeks later and finish it along with 7 other film backs loaded with all kinds of different films.

But more than anything, I love, love, LOVE the way a truly masterfully printed silver gelatin print looks compared to the very best digital output...and so do the people who buy them from me....and it never had to see a computer. Most of us fine art pros find that our costumers really appreciate that what we do is truly hand made in a world that everything seems to have been cheapened if not hastened by a computer. If you have a great eye, true raw talent and want to do fine art, you would be wise to further differentiate your self from the digi-masses and perhaps consider using film, just my opinion.

I can understand why you don't understand this though, you are not a photographer but instead, a doctor as it would seem, who happens to have no photos on his website. The way you think is the way many amateurs think about digital, that it is not only the greatest thing ever, but that it is better than other mediums and makes everything before it obsolete.

A little more self education will reveal that not only is this not true, it never will be.

Kudos to both Dave Howard (ucphoto) and whoever "Film_Ruled" is for masterful posts on the subject.

My comment in this thread has been mentioned by others already: sales volumes are so low in MF that they are reaching, or I would soon expect them to reach, the inflection points on cost where too few people can support the costs and the manufacturers break down. So the current MF industry may not "die", but I believe it's very likely to change dramatically over the next 5 years. How exactly, I'll be curious to see.

In my case, MF is just a curiosity. I can't live without the versatility, portability, ruggedness, and adaptability of a DSLR system.
