No offense, but do you actually ever shoot photographs of anything?
Why yes.... I do actually shoot photographs of things. I show my work internationally, have had solo and group gallery shows on the west and east coasts (including New York and San Francisco) and have gallery representation. Thanks for letting me plug it.
Yes.... 35MM film has grain, and setting aside for the moment that sometimes grain can be used to great effect, the speed, type, and processing of the film can affect the size of the grain.
However....
Digital has pixelation. Yeah.... you can overcome much of the pixelation at larger print sizes by interpolation ("Genuine Fractals" does a spectacular job) but this only goes so far.
And.... you want less grain?? Go to Medium Format... or my personal preference, Large Format (I shoot primarily 4x5 film these days) Or if you don't want grain on your 35mm film? Shoot Kodak Technical Pan film, and process it in the developer only from the C41 process. I challenge anyone to find grain on that on any print smaller than 16"x20"
And with its full 35mm CMOS it is the first camera to effectively reproduce the image quality of 35mm film
Wrong, wrong, wrong....
First, this isn't the first camera to have a full-frame sensor, as others have pointed out.
But let's look at resolution, which is far more important and what people are talking about. And lets convert so we can compare oranges to oranges.
Let's limit our discussion to color negative film... Color Transparency, Black and White, and high resolution (Technical Pan or Gigabit) films are even higher resolution and will cloud the issue.
Film resolution is measured in Line Pairs per Millimeter (lp/mm)... and most consumer color film resolves from 40-65 lp/mm. Doing the math, this equals 1000-1625 lp/inch. To resolve a line pair, you must have 2 lines with a space between them, and to resolve 1 line pair from another, you need to discern a space between the line pairs.... so you need 4 points to resolve a line pair, the equivelent of 4 pixels giving us an effictive film resolution of 4000-6500 pixels per inch.
Continuing the process, a 35mm film frame is approximately 1x1.5 inches, so the effective resolution of normal color film in digital terms is on average 24 to 64 megapixels. Let's take just below the middle and say that Film has an effective resolution of 40 megapixels.
Let's now look at color depth.... The camera actually resolves 8 bits per pixel, and interpolates up to 12 bits from there. Actual depth is only 8 bits or 256 colors. Each grain of film however can register a 1000/1 contrast range, across it's spectrum of sensitivity. If you just consider the single grain you get a 1000 color depth. Since multiple grains are involved in one of the effictive pixels, the reality is closer to 3000 colors per pixel.

I'm not a film snob..... but we're still years away from digital resolution approaching the resolution and color depth of film.
If Katie T. and Penguin really are this mean-spirited and greedy then I do hope that someone steps forward and helps Katie J. fund a legal challenge.
Er..... someone?? Why the hell not us.
Where's the EFF? Where's the legal defense fund to which I can donate? If my site were infringed like this I'd fight it to the nines, and ask for all the help I could get from the Slashdot crowd. People make fun of stealing Slashdot's name..... but this is precident people. I keep seeing glimmers here on Slashdot that people are waking up to the fact that the internet is part of the REAL WORLD, and that we have to play in that world... usually by their rules. Then I see people here whining about how bad this is and how we should slam the reviews on Amazon or boycott Penguin. Both are reasonable ideas.... but we need to get organized and active, and protect ourselves on their terms.
I sent an email to Katie Jones imploring her to seek the assistance of the EFF and to set up a fund for the defense of her rights. I'll happily support both with my wallet to the best I can.
Not to mention that while investigating new cell carriers (I haven't given up totally on Cingular.... but, I'm exploring) I dropped into ATT. They're telling people that to swithc FROM cingular TO ATT will take at least 5 days, during which you will receive NO calls on either phone, although you can make outgoing calls on your new ATT service.
So let's compare... lpmm = Lines of resolution per millimeter... basically linear pixels per millimeter.
Fast color film is about 100 lpmm Slow color film is about 175-200 lpmm Fast B&W film is 250 lpmm Slow B&W film is 300-320 lpmm so-called Gigabit film (B&W) is about 400 lpmm
This camera has 112.66666667 linear pixels per mm.
Gimme my 4x5 inch negatives made with Kodak Technical Pan anytime.... It'll kick the pants off any digital camera.
