Hello,

Recently I was checking to see if there was any light getting

through the shutter curtains by performing the flashlight test.

Would shining that very bright light into that mirror chamber with

the mirror locked up damage the auto focusing or light metering

sensors? Or when the mirror is locked up, (Elan 7E), does that

cover these sensors up from light, and any possible damage?

Thank you,

OK, so light passes through the SLR mirror to be analysed by the

light meter and AF points. Where exactly is the light meter and AF

points located? Are they located on the mirror or elsewhere?

Thank you,

Hello,

I want to know how long I can leave the batteries in my Elan 7E when

I'm not using it, before possible damage can occur?

Thank you

I would really appreciate it if you could explain to me how bright

light interferes with the exposure before the shutter is released,

when the mirror is in the up position. Does some light get through

the shutter curtains to the film, and if so how so? Or, does bright

light interfere with the automatic exposure settings that were set

accordingly for the picture before the mirror was locked up?

Thank you

Hello,

I understand that clear filters should be used to keep the lens from

getting scratched or dirty. I would like to know what a UV filter

does? Can a lens get damaged from direct sunlight? I don't mean by

the heat that sunlight produces but by sunlight entering the lens

directly. Is that what a UV filter is for?

Thanks for the help,

CHH

Hello,

I recently purchased a 75-300mm USM lens. I noticed that when the

zoom part of the lens is extended, (the top part that extends out),

there is some play, it is a little loose, between that part and the

body of the lens where the zoom ring is located. The focusing ring

is also a little loose. Is this normal? I would think that the

lenses in the lens would have to be in perfect alignment. When

replying to this remember that I said, "A LITTLE LOOSE".

Thank you,

Hello,

I'm curious to know if a negative's quality is based on the quality

of the exposing process during processing? Can the negatives

quality be lessened after the picture is taken, or once the picture

is taken that is the permanent quality, no matter were you take the

film for processing?

Hello,

If I were to leave my camera on by mistake, for say.....one or two

days, would that damage any of the internal electrical cicuitry in

the body or the lens?

Thank you,

If there is a bit of dust on my lens, will it show in my pictures?

Thanks,

Can anyone tell me the safest way to clean my lens using products

from home, (cloth & fluid)? If there is a bit of dust on the lens

will it show in my pictures?

Hello,

I recently cleaned the mirror on my new ELAN 7E because it looked

like there was some residue on the mirror from manufacturing. It

looked like little specks of something. So I used a dry q-tip to

remove them. I only pressed hard enough to take them off. Now,

some people are saying that it's ok to use a q-tip on the mirror and

some people are saying that it is not ok. Because it scratches it.

I looked very closely at the mirror after I cleaned it and it looked

spotless, better than it looked when I first purchased the camera.

How can a SOFT q-tip, with barely any pressure applied, scratch

something as hard as the mirror surface? Besides when camera

servicing centers clean the mirror, they must use something simmilar

to a q-tip, because there isn't anything softer, or not much

softer. How can a SLIGHTLY scratched mirror affect the outcome of

your pictures anyway, when it is used in a pre shutter release stage?

Hello,

Can anyone tell me how to lock the EOS ELAN 7 shutter for

astrophotography? And does it drain the battery when opened for a

prolonged time?

Thank you.

Hello,

I recently purchased a Canon Elan 7E QD. I'm aware that the shutter

curtains are one of the most delicate and sensitive components of

the camera. I happened to notice that the curtains, (though not

bent or anything like that), don't really lie perfectly flat on each

other. I noticed this when i hold it under light and view the

curtains at a very slant view (bottom-up). Is this common? Do I

have to do anything? By the way, when viewed straight the curtains

look perfectly ok. Even if the curtains are slightly damaged,

(slightly bent), do they overlap enough so that stray light CANNOT

enter to the film. I appreciate your help on this matter.
