Iso led keeps flashing on my eos 10s

Hi. Open the camera back and pull the film further over towards the pick up spool, close the back and try again to take a photo, i had the same problem with an eos 650 and it always worked.Good luck.

decrease shutter speed, increase aperture size (lower F-stop), and/or increase ISO.

That's odd that the pictures would be coming out under exposed unless the previous owner has gone into the camera functions and switched the ISO from auto to manual. Another reason is that the exposure compensation has been activated and set for - exposure

Under "normal" use the camera will read the DX code on the film canisters and adjust the ISO automatically. However the previous owner may have shut this off in preference to setting the ISO manually. Even though you have ISO 400 in the camera the ISO on in the camera setting may be ISO 1600.

Checking for the Auto ISO and exposure compensation is fairly easy as you can see the film canister through the film window or you know you have loaded 400 speed film. on the LCD panel at the back of the camera is an ISO icon and exposure compensation.

Make sure the ISO for the camera is the same as what you have loaded and if the exposure compensation is to the right of 0 then the resulting picture will be dark. Move this back to the Zero.

I wasn't able to find an exact manual (if you don't have one) for your camera but have found a camera with similar. Here is a ling for that manual.

Hope this was a help

Try shooting with ISO value of 200 or less; or set to "Auto".

If you're missing the manual, you can get it in English, here. Page 76 briefly discusses ISO settings. This camera can select an ISO as high as 1600. ISO has to do with graininess of film - the higher the number - the more grainy the images. Higher ISOs are selected when light levels are low and no flash is used or is usable (such as when the subject is too distant). Some photographers use higher ISO settings with high shutter speeds to stop fast moving objects (like wheels on a race car). The grainier the film, the quicker it captures light. Fime grained film takes longer to capture light.

Generally, pictures taken outdoors in sunshine look best when ISO is 100 or less. 100 is a good choice for well lit indoor pictures, too; but may be better with an ISO of 200. ISO works like this:

If a picture can be properly exposed with an ISO of 100 in 1/15 sec, it would require only 1/30 sec at ISO 200, or 1/60 sec at ISO 400. When you double the ISO value, the exposure times are halved. What's the big deal about 1/15sec, 1/30 or 1/60 sec you might ask? Easy! the picture will probably be blurry at 1/15 and even 1/30 sec exposure time, due to the camera recording even the slightest movement of your hands. You'll need to supply a tripod or do something else (such as increase the size of the opening of the aperture or f-stop) to get a properly exposed image.

I hope this helped - if it isn't an ISO problem - let me know. Good luck!

The flash is automatic, you cannot control the flash. But you can put some black tape over the flash if you really don't want flash. Remember though, if the camera meter decides flash is needed, then your pictures could turn out dark/underexposed by covering the flash.

The manual can be found here: http://www.olympus-europa.com/consumer/208_manuals.cfm?prodID=P_N1246352

The manual says use 100, 200 or 400 iso films.

Maybe try high iso film like 800 iso or 1600 iso, best to try this out ahead of time to make sure you are satisfied with the results. The high iso films need less light so should perform better without flash, but the camera may not be able to rate these films correctly, trial and error is definitely required.

ISO refers to the sensitivity to light of the sensor. It's like film speed ratings on film cameras (ie. a 400 speed film is four times faster than a 100 speed film). There should be a button with a lightning bolt icon on the back of your camera. Press it and watch the screen for different options for flash. Stop when you get to the "A" or "Auto" plus the lightning bolt.

If it's not too dark, you can try setting the ISO to 1600 or even 3200. The downside is, you'll got image noise at higher ISO (sensitivity of sensor/film).

The other alternative is using the flash. If you need to increase shutter speed beyond the capabilities of the on-camera flash in order to 'freeze' the moving subject, then use an external flash unit and set it on high speed sync.

Did You ever use a SLR back in the stone age when all we had was film?
Film was/is rated with a ISO number, the higher the number the faster the film.
Fast film had fewer and larger grains of silver iodide, (the particles that changed tone, color etc.when exposed to light), therefore it took less light to take a picture.

The down side was a increase in grain. Large grains meant that blow ups, 8x10, 11x14, posters, etc were not as sharp,
as with slow ( low ISO film)
Most outdoor photos had plenty of light so the film had more grains ( high ISO) to capture the available light, and the result was a much sharper image.

Portrait photography used very very slow film ( your 50 ISO setting) but in a studio you had all the artificial lighting you needed, so your portrait came out with very fine detail.

Now the FE-280 does not have a shutter setting, but we can compensate by changing the ISO setting, and the overall effect will be.
Fastest= 1600 ISO for very little light and poorest picture quality.
Slowest=50 ISO for plenty of light and the highest picture quality

200 ISO was the most popular because it worked well outdoors and indoors with a flash, with very good overall picture quality.

400 ISO was a good choice for gloomy days and medium lighting conditions.

Your ISO settings on the FE-280 will have a similar effect.
My best advice is to play around with the different settings until you develop a knack for it, we used to use light meters and a lot of guesswork, quite expensive when you had to buy film and pay for processing.

OK enough history. heres how....
Turn dial to (P) PROGRAMAUTO
Press (MENU)
The camera menu in center is bracketed, Press (OK)
Scroll down one bar on the on screen menu to (ISO)
Press (OK)
Scroll up or down to desired ISO
Press (OK)
TAH DA !

All other functions will be automatic or any other setting that you might choose..
If you change the dial and later go back again to (P) it will retain your selected ISO setting, which is displayed, on screen.

I hope I was help full, and you enjoy some of the special effects that you will now be able try.
By the way... good taste in cameras.
Best regards, Paul
