I don't know how to buy film for this camera. is it just 35mm 400 film

The Kodak Star 435 uses standard 35mm film, also known as size 135. 35mm film is available in a variety of lengths: 12-, 20-, 24, and 36-exposure. You can get 35mm film for black-and-white prints, color prints, and color slides at any decent camera store. Many supermarkets and drugstores also carry 35mm film, though not as wide a selection. And, of course, you can buy film online.

I have a Minolta maxxum 400 sl that's in like new condition, only has had 10 rolls of film run through it. Would you like to buy it ?

You can use any brand of film in any camera, as long as it is the same size i.e 35mm. so yes absolutely

when you place the film in the camera & close the door does the film advance ?

You may download a copy of the manual from here.

Is the film you're using DX coded? Have you manually set the film speed using the ISO button?

With the camera turned on, look in the viewfinder. Down on the bottom right side is an LCD display, if it's blank then your camera probably has dead batteries. It takes 2 x CR1/3N or 4 x SR44.

Your film accepts 35mm negative film or 35mm transparency (aka slide) film. It will accept any ISO from 12 to 3200, but in practice all you'll usually need are ISO 100, ISO 200 or ISO 400. You choose the film based upon lighting conditions and the lenses you'll be using, but in general you'll use ISO 100 if shooting mainly outdoors in daylight, ISO 400 if shooting in low light or with a telephoto lens, and ISO 200 is a general all-rounder good for most things. ISO is usually referred to as film speed as higher numbers need less exposure than lower numbers but the trade-off is a less detailed image.

To load film into your camera and to set the camera to match the film ISO setting refer to this link to the manual provided by Norman Butkus. The manual will also guide you through all other aspects of operating your camera.

I hope that I have fully answered your question, but if not please add a comment and I shall respond in due course. If your question has been answered, then please let me know by taking a moment to rate my answer.

try Kodak ISO, ( ASA), 400 ( DIN 27 Degree ) 35 mm film to start. if you like the results, stick with it. remember the faster the film the higher the grain. the slower the film the finer the grain, sharper enlargments with finer grain.
