It's simply not cost effective to shoot film if you're interested in some point getting a DSLR. It's more expensive resource wise, but it forces you to learn quicker since you're literally paying for every shot. However, if you save and go for digital (which inevitably will be the way all camera's will go. Whether any film fanatic wants to admit it or not) you can practice composition along the way, and make sure that you are still interested in photography in a few months time. Before you know it, you'll have a 10D or 20D, and a 50mm f/1.8. The perfect setup to get your feet wet in the world of full manual controls, and learning the exposure triangle.
now lets hear it from someone who actually DOES shoot both formats and knows what they cost.
Canon 7d body = roughly 1500 dollars depending on where you shop. I've seen them cheaper.
Canon EOS 3, the 35mm equivalent to the 7d (more accurately the 5d) used copies trade for about 300 with the power booster.
A roll of professional grade film, something nice, how about FujiFilm Pro 400h, good stuff, I pay about 9 dollars a roll, with my student discount 7.50 after tax.
Now you will need some glass, so how about 3 lenses, the 28-135 IS, Nifty Fifty 50mm 1.8 (astonishing lens) and a 70-300 IS. All the focal points covered for under a grand, around 800 dollars for all those lenses.
Subtotal.....
Canon 7d, lenses = 2300 dollars. Make it 2370 with cleaning accessories and a nice memory card
Canon EOS 3, lenses = 1100 dollars.
Now, film.
Roll of nice film, about 9 bucks, let's make it 10 because I suck at math and 10 is a nice round number.
10 bucks a roll, and to professionally develop and print for me is like 20 bucks and I get a CD. Net cost is 30 dollars each roll, you would have to shoot +40 rolls of film just to break even on a 7d. And that's expensive film, not even cheap stuff that looks almost as good. And when it's all said and done, and you save up for your 7d, you got an awesome 35mm companion to your bag that uses all your nice lenses.
You don't even need something super nice like an EOS 3 I have an Elan 7e that costs more than half as much as an EOS 3, and those Nikon FG's I mentioned earlier can be had for 50 bucks, which is dirt cheap and produces just as good an image.
Bottom line, I shoot both formats and have been behind the wheel of everything from my FujiFilm point and shoot to my bud's 1ds Mark III + 70-200 f2.8L IS, if I could only shoot one camera the rest of my life it would be a Nikon F. Enthusiasts, artists and curious people like yourself are what keeps film alive, and it is a growing format again. Both formats have their highlights and downfalls. Digital is a great learning tool but 200 years from now where will your digital images be?
I swear to God threads like this need to be stickied somewhere.
