| 151470 | 2003-06-11 22:08:00 | Is this the camera (www.camera.canon.com.my) that you have nomad? It may be "entry level" but it has a pretty full-on set of features. One or the other of the operating modes must allow you to preview depth of field effects through the lense, even if you have to do that in manual mode. My pick would be a partial depression of the shutter button. Before you spend time and money experiemnting with films, either go back to the shop where you bought it or do a search for a camera forum (sorry, I don't have time to do that for you) and post the simple question there "how can I preview depth of field through the lense etc" You will have to flesh out the question yourself. If you have bought this camera to use at a photography course, I strongly recommend that you go to your local library and borrow a few books on photography in general and the principles of camera operation or you may be left floundering. IMHO you need a grasp of the basic principles to start with. In answer to an earlier question, whatever you learn on this camera will transfer to future cameras. Shutter speeds, Focussing, F stops and film speeds are constants. Cheers Billy 8-{) |

| 151473 | 2003-06-12 05:22:00 | Go for it. Cameras are a lot of fun but the only way to learn is to take pictures. You need to make a note of your settings to learn from the results. Bracketing photos as suggested is the fastest way to learn. If your camera has a preview mode then try to find it. Otherwise the diaphragm should close down in Manual mode as you change the f stop. You probably realise that f stops go from large to small (or fast to slow) in exact opposition to the numbers. Accordingly f1.2 is extremely fast and large (and expensive-don't bother looking for such a lens) whereas f 16 and f 22 are slow and small. The f stop is a function of the diameter of your lens. f 22 means that the hole the light enters through the diaphragm aperture in your lens is 1/22nd of the width of the lens. So it is a very small hole. A small f stop makes the light rays strike the film at a fairly perpendicular angle and thus are mostly all in focus. You also get richer colour saturation at small appertures. By contrast a fast f stop f2.2 or whatever your zoom can manage means that many of the light rays enter through a big hole at oblique angles and are out of focus by the time they hit the film. Thus only the subject of the lens's precise focus remains in focus at the film plane. I use a Canon EOS 1000 with two USM zoom lenses. I am very happy with this camera. Generally I just use a fast f stop for portraits of individual people such as my children. Otherwise the automatic fuzzy logic all-in-one program seems to do everything well. What I want is a decent digital body to use my lenses with but the manufacturers seem to see more money in developing new digital SLR cameras. The prices are extraordinary. Go to a course and/or get a book from the library. More userfriendly than being tied to a computer in my oldfashioned opinion. Cheers Winston001 |

| 151474 | 2003-06-12 05:43:00 | Very good advice Winston, But one slight correction to this statement: "f 22 means that the hole the light enters through the diaphragm aperture in your lens is 1/22nd of the width of the lens." Not quite, f22 means that the aperture hole is 1/22 of the 'focal length of the lens' f stops & other details like depth of field are explained on this site: www.cybercollege.com Cheers. |

| 151475 | 2003-06-12 06:08:00 | Excuse my ignorance here ppl but, with my old OM1 some of the lenses came with a preview button on the lens. The preview is therefore a function of the lens independent of any preview function built into the camera body, right? Do they still produce lenses with this function that Nomad could purchase for his camera. I still regard bracketing as an important learning device regardless of the camera and what other education resourse is used. Cheers Murray P |

| 151477 | 2003-06-12 09:19:00 | Muzzer The OM1 was a manual model so far as I recall as opposed to the OM2. Anyway most modern lenses that I have seen do not have the preview button. I have an old Fujica with this function on both of its lenses. Lenses tend to be made for the mass market and I doubt there is much demand for the preview ability with the average camera user. To be fair cameras over the past 15 years have become virtually idiot proof. |
