Leica Wide angle lens focusing aid

Just wonder if there is any focusing aid by using the Leica Wide angle

M lenses e.g. 24mm 21mm lenses. I know there are external finders for them. How do your focus the lens? Is the camera finder can be used for focusing? How about the parallax correction? Thanks.

You use the rangefinder in the camera to focus. The finders have a set

of lines that roughly indicate the parallax correction at close

distances. In that regard you guess a bit. It all works in the end,

though.

By the time you get to 21mm, you really don't need a focusing aid.

Practice distance estimation, and you won't have any problem, except

maybe wide open. You can work on this with any lens, just walk down

the street, focus on something and guess the distance. After a while

you can do it pretty well.

Parallax is something you can also learn to estimate. Shoot

constantly and review the results. After a while you will know where

the frame really ends.

After a while, you will be shooting without looking through the

finder...

yeah, and the depth of field scale is little more than an ornament on

those wide lenses. With the 21 you practically have to TRY to get

something out of focus! :)

Rats, I keep forgetting to use rowlett@mail.com instead of alaska.net
