The Bronica GS-1 is a strange camera, because it has film backs for 6x6, 6x7, 6x4.5, 6x2.4(35mm) and normal 35mm. The medium format back are for 120 and 220 type film. There are also different matglasses for the different film types!

The 645 series has a flash sync of 1/60 not 1/30. Perhaps you were thinking of the 6x7, which has a flash sync speed of 1/30.

I now have a Pentax 645N with 75mm and 150mm lenses. I also have decided on a couple of film stocks, which I will likely blog about as I get time.

Right now I am putting together darkroom gear. That I will surely write about!

After "which format" you need to decide which type of film. For my first roll, I'm leaning towards Kodak Ektra, which is C41 negative film, maybe the kodak B&W C41 film. And then have it scanned/printed at Costco at 6 megapixels. I'm looking forward to trying the 28mm F/2.8, which is wide angle with selective dof, which is the only fov/dof combination that I think APSC digital can't reproduce. But first, I need to wait for the camera to arrive.

Any progress on which camera/lenses you're getting.?

Thanks for the detailed comment. I look forward to hearing from you as your adventure to 35mm continues. I too thought that digital is likely the equal of that format which is why I decided to leapfrog it to 645. But each format offers its own advantages.

As for comparing formats, there is certainly some debate. Your comments anticipate my next post, so I'll leave discussion until then.

I have a k2000, haven't shot film in awhile, but also pondering experimenting with film. I decided I'm going the 35mm route, since I can pick up a second hand 35mm camera cheaper, and since pentax 35mm is compatible with some of my pentax lenses, and since 35mm film and developing/scanning/printing is cheaper and more readily available than it is for 120 film.

My assumption is the 10 megapixel K2000 is superior in every way to standard 35mm film, but that film might give some creative advantages since it forces you to slow down, and think about what your shooting. I'll find out next week, when the camera I bought on EBay arrives.

I would compare format by the area of the negative, not the linear enlargement, so APS digital to FF digital would be 2.25x which is 1.5x squared. And 645 compared to 35mm would be 2.7x and 6x7 compared to 35mm would be 4.5x, and the APS digitial to 645 multipler would be 6.3

But the focal length is linear, so use the square root of the area multiplier. So a 28mm F/2.8 lens for APS digital is analogous to a 42mm F/4.2 lens on 35mm film, and a 70mm F/7.0 lens for 645. All three would have the same DOF characteristics, if enlarged to the same area.
