I recently purchased an Eyepiece Extender (EP-EX15) from Canon for

EOS Rebel Ti (300V). The thing seems comfortable. It extends the

eyepiece by 15mm from the camera body and that way relieves your nose

from pressing against the camera back. However, it increases the

magnification by a factor of about 0,5.

How bad a low magnification is indeed and what exactly does it effect

on? Also, why are the viewfinders with higher magnification

considered better?

Thanks for your input in advance.

First of all thanks a lot for your comments!

I don't have metering problems. At least I think I don't have them, since I am shooting negative film and as far as I know prints from negatives are very much corrected by labs. Today I shoot my first roll of a positive film and now I'm waiting for the results. I used a grey card all the time while shooting, but I am not sure whether I used it correct or not. Even a slight movement of the card would give me a different exposure value and as you know slides are not tolerant towards even slight changes. So, that's why I though hand-held meters always give "correct" exposure at their best and it's a good idea to have them. But definitely need some advice and feedback from the people who know more.

I owe Canon EOS 300V, an entry-level low-end SLR. My question is:

how important and necessary is for a beginner photographer to have a

high quality light meter (incident or reflective, or both)? Is it

worth to spend money for that?

How good a built-in camera meter (in EOS 300V) can be? And is it

enough for a beginner?

Thanks for your comments in advance.

What does "Full Time Manual" exactly mean? Does it mean that I can keep my lens in AF mode and rotate a focus ring anytime in order to adjust the focus without changing the MF mode?

Thank you!

Today I was told by one of the assistants of one of the photo stores

in Koeln, Germany that multi coating is extremely important for

filters for colour film, polarizing filter, UV filter, etc... and it

is not necessary for filters for black and white film (e.g. red 25,

yellow 8, green-yellow 11, etc.); Therefore he advised me to get B+W

filters for black and white film without MRC (multi resistant

coating). Is this a wise advice?

Any comment of yours will be highly appreciated. Thank you beforehand.

As far as I know, black and white panchromatic films used without a

filter with tungsten illumination tend to record reds and blues too

light and therefore, often a "light green" filter is used as a

correction.

My question is which green filter will be considered as a "light

green" filter? For example, B+W makes two types of green filters:

060 yellow-green (Kodak numbering 11) and 061 green (Kodak numbering

13).

Thank you!
