In this case, fun with wrong economics
😉
I sold my F6 in 2009 to help fund my purchase of a D700. It got me about half way there - the F6 sold for about £850 and the D700 cost £1700.
I loved the D700 and kept it for 5 years, taking around 20,000 shots with it.
And at how much of that will you ever look again?
How much are keepers?
How much will be buried on your computer?
If you don't look at them again it has been just a waste of effort, time and money.
I hear that so often: "I've made 20k, 30k, 50k shots with my new digital cam in only 2,3, 4 years".
And when I asked whether they have looked again at these incredible huge amount of pictures they stare at me and stutter "no".
Crazy......picture inflation.
Not a huge amount for a digital camera, but that's very approximately, 555 rolls of film. I sold the D700 in 2014, also for £850. I presume the used F6 would still be worth £850 in 2014, perhaps a little less. Cost per digital image £0.0425 (about 6 US cents)At £10/roll for develop and print £5550, cost per film image £0.2775 (about 40 US cents). Ouch.
1. If you have kept the F6 you most probably would have not shot so much.
You would have had more self discipline: Thinking first, then taking the picture.
Resulting in a much higher keeper rate.
I've observed that with me when I've gone back to film.
And with the F6 I have the highest keeper rate of all cameras I've ever used, film and digital.
2. I've bought my F6 even brand new. But I will use it for the rest of my live (not possible with a D700 e.g.).
It's like "a once in a lifetime" purchase. Same is valid for the second one I plan to buy.
So the cost per single shot will be negligible over the years.
In the same period I would have to buy several digital cameras.
And several computers, which are needed for digital imaging.
3. You've ignored the storage costs for the pictures. These are much much lower with film compared to digital (having better safety, too).
Take some time and read this scientific evaluation of this topic:
http://www.oscars.org/science-technology/sci-tech-projects/digital-dilemma-2
All digital movies are stored exclusively on film, because it is
- much more safe
- has about factor 11x (!) lower costs.
4. You have sold your D700. So you are now either without a camera, or you have bought another digital camera.
You have to add these costs of the new cam to your calculation, too.
Because in case of keeping the F6, you would have a camera.
Digital is not cheaper than film in general, if you consider the whole costs. The cost structure is just different. In digital imaging you have other cost factors than with film.
