Aperature ring adjusting the ring doesnt adjusting the aperature

Leave the aperture ring at f/22. You can then control the aperture from the camera body, the same way you would with a lens without an aperture ring.

It is indicatin that there is a problem with the aperature coupling to the lens.

If the lens has an aperature control ring twist it round to either the samllest f-stop ( largest number ! ) or to the 'A' setting is it has one.

If it is a later lens that does not have a ring, try twisting the lens off and on a few times to clean the contacts, or wipe the contacts on the back of the lens and body with a dry rag.

There should also be a switch arm to the left of the lens mount, at about the 8 o'clock position - this should be pushed by the lens in the conditions above - make sure it is not jammed.

Your aperture lenses should be set to the biggest f-stop (smallest aperture)

make sure the aperture ring on the lens is set to it's HIGHEST number (f22 or f32) it might be a different color than the others and flip the little switch that locks it into place.

This is the error code for having a lens with manual or auto aperature adjustment in manual mode with the camera in anything other than "M". You need to put the lens in the max aperature (usually it's red) and then move the small red switch to the red dot. I don't think anything else will give you this error.

Did you try twisting the aperature ring to release the lens cap? You can't just pull it off, as the body cap locks on by twisting the aperature ring.

put simply the ISO number is how sensitive the film is to light, the higher the number the more sensitive the film. The ISO on the camera sets the exposure system to give the proper exposure for that film (the f/n80 usually sets the ISO automaticly). Also the higher the ISO the more grainy the picture, I would recommend using ISO 200 film for the pictures you describe. I would set the camera to the P setting it is a good all-around setting.

Check the operators manual - you need to 'activate' the aperture control.

The aperature error is due to the fact that the lens in not a constant aperature design. The settings on the LCD are assuming you are at full wide angle setting. As this lens moves towards telephoto, the aperature changes about 2/3 of an f-stop due to the mechanical movement of the lens elements. So a manual setting of f4.0 at full telephoto will be more llike f5.0 in reality. It is too bad Epson could not make the mechanical aperature adjust to compensate, but every nice feature costs something. I have not had any issue with the shutter speed changing. One guess is that the camera has shutter speed/aperature combinations that it can't achieve due to mechanical limitations, so it chooses the available combination. Another is that it wasn't in manual mode, but rather aperature priority mode and the final adjustments changed the speed.

Yes. You pick the apature (the 3000 keeps it aorund the setting you pick) and then it automaticly adjusts the speed for you.
