Dan Tamarkin here from Tamarkin Camera in downtown Chicago

to talk a little bit about how to choose a Leica M lens.

The first thing to understand about Leica M cameras

which means you're looking through this little window.

You're not actually looking through the lens itself.

It's very important to understand, in choosing Leica lenses,

you're simply looking through this piece of glass,

which has these little bright frame lines inside of it.

the proper bright frame lines appear up here in the range finder,

However, you can only have one lens on the camera at a time,

that you will be using to compose your images

is the first step in choosing a Leica lens.

Here, on the table, we have a number of 50mm lenses,

some from the 1950s, 1970s, 80, 90s, currently manufactured.

All of the lenses snap right into the body,

They all have focus, and they all have aperture.

These are the important facets of any photographic lens.

is that you have this mechanical connection here.

and it, in turn, moves this little lever,

and the optics are the best in the world.

Why do all Leica users use these funny words,

like Summicron, Summilux, Elmarit, and Noctilux?

All of these terms are trademark Leica terms

that's the widest aperture that the lens has.

which is the fastest production lens in the world.

All of these Leica M lenses are extremely compact,

and they all work on the older M cameras,,

will work just fine on a modern Leica M digital camera.

Nonetheless, it's very important to choose

that Leica uses in their manufacturing of their lenses.

which stands for apochromatically corrected,

Apochromatic correction addresses an anomaly

or colors shift and are not rendered necessarily correctly.

You can get color fringing and all kinds of other effects

So, some of the lenses that Leica designs,

such as the APO aspherical 50mm Summicron,

and all of the light rays to meet on the film plane

APO stands for apochromatically corrected,

and there is benefit in having an APO lens,

It means that the lens renders more sharply,

with high contrast, all kinds of good things.

The other designation addresses spherical aberration,

which is the other kind of aberration that

is that aspherical lenses generally are less prone to flare,

and the edges of the photograph are generally sharper,

higher contrast, and with better color rendering.

However, the important thing to understand
