I went back to film a few months ago, about 15 years since I shot film. I had my beautiful Canon A1 CLA'd then bought a Pentax 645 to shoot 120. Love to be shooting film again (I shoot digital on assignment). I just bought a Canon Elan from a camera shop Friday, it was $50 w/ the kit lens. I causally mentioned how the lens won't get much use as I have 8-9 very good lenses & some L glass. I just assumed it was a "kit" but he took the lens off & sold it to me for $35. Very weird shooting my 24-70mmL on a film camera.
The cost of everything film has gone up quite a bit, but there are ways to help. I bought the changing bag, Patterson tank, chemicals, sous vide, & an Epson V600 scanner (this was the highest price) for just under $500. Sending a roll of film to the lab for development & lowest res scan is $12 for 35mm & 120/620 (because I shoot some old cameras). This is a fair price as far as market goes, but still can add up. Once I got over the fear of developing at home I could afford to shoot more film. The last batch of color chems I bought this week cost $29 total w/ tax, free shipping. This is enough chems to do approx. 25 rolls, which is around $1.20 per roll, exactly 10% of lab fees. Plus there is no return shipping to pay. Also, I'm scanning myself at high res instead of relying on the cheaper, low res scans from the lab (the lab fees increase by $3 increments per res increase, $12, $15, $18). Even the lab's $18 high res scan is lower res than I scan with my Epson.
Developing at home has become so easy & saves so much money. Truthfully, the hardest part of home developing is getting the film on those damn reels!! By far not an expert but will (try to)answer any questions you might have.
