The Leica Digilux 1 Review

To me, there was three reasons to get this camera:

1. The Leica Digilux 1 delivers film-like pictures and not the flat, video-like pictures that most digital cameras produce. When you look for digital, you look at lots of closeup shots which show the difference in details from different digital cameras. You look for clean, sharp pictures. However, at some point I started looking at the whole picture and there the Digilux 1 just stands out.

2. Ease of use. Logic. Cool design. Unbreakable. Even my kids can use it. It feels and looks like a camera, not a piece of electronic equipment.

3. The f/2.0 lens which allows one to take pictures "in the dark" at 100 ISO (nonoe of the current 2002-digital cameras, in my opinion at least, can deliver 200 or 400 ISO without loss in quality). The Digilux 1 allows you to take pictures at 100 ISO where most cameras need 200 or 400 ISO to do the same, due to the lightstrong lens.

Overall, it's a very cool retro-looking camera. The Leica 7-21mm Vario-Summicron ASPH f/2.2 - f/2.5 is equivalent to a 33 to 100 mm lens for the 35mm format. It's a auto focus lens but also have a manual focusing ring on the lens.

Leica Digilux 1 Definitions:

AF = Auto Focus. The idea is that the camera does the focusing itself (the word auto comes from Greek "self").

Aperture = (also written as f/) = The metal blades inside a camera lens that regulates how much light passes through the lens. On a f/1.4 lens, the lens is "fully open" at f/1.4. At f/2.0 the aperture inside the lens makes the hole through the lens smaller so only half the amount of light at f/1.4 passes through. For each f/-stop (like f/4.0 - f/5.6 - f/8.0 - f/11 - f/16) you halve the light. The f/ fundamentally means "f divided with": The aperture of the lens is basically the focal length divided with the f/-stop = size of the hole (50mm divided with f/2.0 = the hole is 25 mm in diameter, or 50mm at f/1.4 is 50mm divided with 1.4 = the hole through is 36mm. ). ORIGIN: Late Middle English : from Latin apertura, from apert- ‘opened,’ from aperire ‘to open’.

ASPH = stands for "aspheric design". Most lenses have a spherical design - that is, the radius of curvature is constant. These are easy to manufacture by grinding while "spinning" the glass. This design however restricts the number of optical corrections that can be made to the design to render the most realistic image possible. ASPH lenses, however, involve usually 1 element that does *not* have a constant radius of curvature. These elements can be made by 1) expensive manual grinding, 2) molded plastic, or 3) Leica's patented "press" process, where the element is pressed into an aspherical ("non-spherical") shape. This design allows Leica to introduce corrections into compact lens designs that weren't possible before. Practically, the lens performs "better" (up to interpretation) due to increased correction of the image, in a package not significantly bigger than the spherical version. Sphere: ORIGIN Middle English : from Old French espere, from late Latin sphera, earlier sphaera, from Greek sphaira "ball".

Normal spheric lens (grinded)		ASPH (note the shape of the glass as result of pressing rather than grinding)

Auto- means “self”. The idea is that when a camera has auto-(something), it does that (something) by itself.

Bokeh = The visual quality of the out-of-focus areas of a photographic image, especially as rendered by a particular lens: It's a matter of taste and usually photographers discuss a 'nice' or 'pleasant' bokeh (the out-of-focus area is always unsharp, which is why the quality discussed is if one likes the way it renders or not by a particular lens). The closer you get to something, the 'more' bokeh' you get (in that the focus becomes less for the background and foreground at close distances than at long distances). ORIGIN from Japanese 'bo-ke' which mean 'fuzzines' or 'blur.'.

Camera - is today’s short name for Camera Obscura (meaning “a dark room”). Camera means Chambre and was used only as a Latin or alien word, actually only for Spanish soldiers’ rooms, until popularized in connection with photography in 1727: “Camera Obscura”. In 1793 the slang term “camera” was used by Sterne Tr. Shandy: “Will make drawings of you in the camera” and by Foster (1878), “The eye is a camera”. Camera Obscura was described by Iraqi scientist Ibn-al-Haytham in his book, “Book of Optics” (1021) and by Leonardo da Vinci in 1500; popularized and made widely known in 1589 by Baptista Porta when he mentioned the principle in his book “Natural Magic”. Johannes Kepler mentions Camera Obscura in 1604.
Camera = chambre (room), Obscura = dark (or cover).

CCD sensor (as used in Leica Digilux 1, Leica M8, M9, Leica S) = (Charged Coupling Devices) - The first digital cameras used CCD to turn images from analog light signals into digital pixels. They're made through a special manufacturing process that allows the conversion to take place in the chip without distortion. This creates high quality sensors that produce excellent images. But, because they require special manufacturing, they are more expensive than their newer CMOS counter parts.

Central Shutter = Some lenses, for example the Leica Digilux 1, the Leica Q and the Leica S lenses where a shutter is located in the lens itself. In most cameras there is a shutter curtain just in front of the sensor, and in SLR (Single Lens Reflex) cameras there is also a mirror in front of the shutter curtain.
In the Leica T/TL/TL2 the shutter is in front of the sensor, but only acts to "refresh" the sensor. In the Leica TL2, there is a mechanical shutter curtain from 30 sec. to 1/4000 shutter times, and digital shutter from 1/4100 to 1/40,000 shutter times. A digital shutter is simply "turning on/off the recording of the sensor.

Contrast - The degree of difference between tones in a picture. Latin contra- ‘against’ + stare ‘stand.’

Digital Zoom = In some cameras, there exist a possibility to enable "digital zoom", which basically means the camera can zoom closer into something than the lens is actually designed to. The way digital zoom works traditionally is that the camera simply crops the picture; so you get closer, but without resolution. In other words, it's the same as if you took a normal photo and then cropped into the center of it.

	Lens distortion looks like this. The lines are not straight. Our eye uses distortion correction. Lens designers can design lenses so they have very little distortion, or they can make less complicated lens designs and "fix" the distortion in software.

Distortion = In photo optics/lenses: When straight lines in a scene don't remain straight because of optical aberration.

Lens designers can correct for distortion to a degree so the whole image field is perfect corrected and all lines remain straight. In modern lens design many designs rely on Software Distortion Correction (SDC).

The eye adjusts for distortion so we always see vertical and horizontal lines straight when we look at things. Even when you get new prescription glasses (if you use such), you will often experience distortion in your new glasses. After a few days they eyes have adjusted for the glasses and the distortion you saw to begin with is now gone. Software Distortion Correction (SDC) is far behind what the human eye can perform of adjustments. (Also see my definition on Perspective for more on the eye and optics)

	DOF scale ont the Leica Q lens

DOF = Depth of Field. This is how much of the image will be in focus or "acceptable sharp". The DOF is determined by the subject distance (the farther away, the larger area is sharp; the closer the focus is, the less of the lage is sharp), the lens aperture (the depth of field is narrow at f/1.4 and larger at f/5.6) and the focal length of the lens (tele lenses has very narrow depth of field whereas wide angle lenses has a wide depth of field) and film or sensor size (small-sensor cameras has a wide depth of field wheras medium format or large format cameras has a very narrow depth of field). As an example, a Leica 21mm Super-Angulon-M f/3.4 lens is sharp all over the focus field from 2 meter to infinity when set at a distance of 3 meters at f/3.4. The DOF scale measurement on top of the Leica lenses shows lines for each f-stop that indicates from which distance to which distance the image will be sharp. Shallow DOF is a generally used term in photography that refer to lenses with very narrow focus tolerance (which can be used to do selective focus; making irrelevant subjects in the foreground and background blurry so only the subjects of essence are in focus and catches the viewers eye).

Depth Of Field scale from Fujifilm.

Depth of Field: Focus is on the flowers and the photograph on the desk and the foreground and background is blurred as the depth of field is narrow. If one stop down the aperture of the lens from f/1.4 to f/5.6, more will be in focus. If one stop down the lens to f/16 even more (if not all) will be in forcus. Another rule: The closer you go to a subject (the less focusing range), the more narrow the Depth of Field will be. © 2017 Thorsten Overgaard.

Depth - Distance between front and back. Distance from viewer and object.

Dynamic range. The grade of ‘contrast range’ (or number of tones) a film or sensor, or simply a photograph, possess between bright and dark tones. The human eye is said to have a dynamic range of 10-14 ‘stops’ (but because we scan area by area and compile a concept of the overall scene, they eye is often thought to have a much higher dynamic range), Film used to have 7-13 ‘stops’ and some modern sensors have up to 15-17 ‘stops’.

Focus, in - Sharp and clear in appearance. Focus - “The burning point (of a lens or mirror)”. In Latin the word focus meant fireplace or hearth. The word was probably first employed outside of its Latin literal use as “the burning point of a lens or mirror” in optics, and then came to mean any central point. The German astronomer Johannes Kepler first recorded the word in this sense in 1604.

	A 28 mm lens has a 74° viewing angle

Focal length = (also written as f-) = On the Leica 35mm Summilux-TL ASPH f/1.4 it is 35mm and originally referred to the distance from the sensor (or film in older days) to the center of focus inside the lens. Nobody uses that measurement, except those who construct lenses! For users of lenses, focal length refers to how wide the lens sees. The viewing angle, which is often given in for example 90° viewing angle for a 21mm lens, 74° viewing angle for a 28mm lens, 6° viewing angle for a 400mm lens, etc.
Each human eye individually has anywhere from a 120° to 200° angle of view, but focuses only in the center.
The Leica TL2 has a APS-C sensor, which "crops" the traditional focal lengths with 1.5X, reducing the angle of view of view with 1.5X.

Full Frame (FF) = The size of the sensor is 24 x 36mm which is the format Oskar Barnack and Leica Camera AG invented with the first Leica that was introduced in 1925. Many other formats invented since, such as APS, APS-C and all usually refer to Full Frame ratio, by which it means what size they have compared to Full Frame.

	Full Frame is "king of photography"

The 24 x 36mm Full Frame format is so "king of photography" that it has continued to be the ideal for all cameras. Besides this, there exists Large Format cameras such as 4x5" (100 x 125 mm) and Medium Format 6x6 (60 x 60mm amongst other sizes in that area).

The sensor size in the Leica Digilux 1 is a 1/1.8" 4 megapixel CCD sensor.

ISO = Light sensitivity of the camera sensor is given in ISO (International Organization for Standardization). It's a standard that was used in film and is now used in all digital cameras also. The base ISO for the Leica TL2 sensor is around 100-150 which means that this is what the sensor "sees". All other levels are computer algorithms calculating the effect as if the sensor could "see" more (hence noise at higher ISO levels).
ISO goes in steps of doubling: When the ISO is raised from 100 ISO to 200 ISO, the camera only need half the amount of light to make the same picture. For each step in ISO to 400, 800, 1600, 3200, etc. the light sensitivity is doubled for the sensor (and the camera sensor only need half the light of the previous ISO to record the same image).

JPEG = A standard for picture format made in the 1990's by Joint Photographic Experts Group). Mostly referred to as JPG as in L1003455.JPG which would be the name for a JPG file from the camera.

Leica = A compound word derived from " (Lei)tz" and "(ca)mera". Apparently they were originally going to use "LECA", but another camera company already used a similar name in France, so they inserted the 'i' to prevent any confusion.

Lens - A piece of glass or similarly transparent material (like water or plastic). It has a shape so that it can direct light rays. The word “Lens” is used both for single piece of glass as well as a camera lens with several lenses that works together. From ‘lentil’ because similar in shape.

Light = Tiny particles called photons that behaves like both waves and particles. Light makes objects visible by reflecting off of them, and in photography that reflecting off of subjects is what creates textures, shapes, colors and luminance. Light in its natural form (emanating from the sun) also gives life to plants and living things, and makes (most) people happier. So far, nobody has been able to determine exactly what light is. The word photography means “writing with light” (photo = light, -graphy = writing). Read more about light in my book Finding the Magic of Light.

mm = millimeter(s), as in a 50mm lens. (Earlier in lens history lenses focal length was given in cm = centimeters; as in a 5 cm lens). For anyone used to centimeters and millimeters, it’s no wonder. But if you grew up with inches, feet and yards, you may have had a hard time grasping what a 50mm lens was. But as lenses were designed first in Europe, the metric system with centimeters and millimeters was used to describe lenses.
The reason a 50mm lens is a 50mm lens is that there is 50mm from the focus plane (the film or sensor) to the center of focus inside the lens. When photography was a young subject, it was engineers who made it all, and the users were expected to understand. The engineers were so into the making of the lenses, that it apparently never dawned upon them that today’s users would think of a 21mm lens as a wide angle lens rather than a lens where there is 21mm from the sensor to the center of focus inside the optics.

Optic = Eye or vision. From French optique or medieval Latin opticus, from Greek optikos, from optos ‘seen.’

Perspective - The way objects appear to the eye; their relative position and distance. Also, selective focus (foreground and background out of focus) can change the perception of perspective (also see Three-dimensional). A wide angle “widens” the perspective and makes objects further away appear smaller than they are to the eye, and objects nearer, relatively larger than they are to the eye. A tele lens will “flatten” the perspective and often objects further away will appear relatively larger than nearer objects, compared to sizes in real life. A 50mm lens is the one closest to the perspective and enlargement ratio of the human eye.

Perspective is relative position and distance. As here where the girl in front is more than two times taller than the people walking, and 8 times taller than the people in the far background. Also, the parts of the buildings closer to the viewer are "taller" than the parts of the same building further away. Late afternoon sun in Denmark.

Sensor = A device that detects a physical property (like light) and records it. A camera sensor is a plane plate with thousands of small “eyes” with a lens in front of each, which each individually records the amount of red, green and blue light rays that comes through the lens. together Red, Green and Blue form all colors of the spectrum. From Latin sens- ‘perceived’.

Saturation: How colorful, intense or pure the color is. Less saturation would be less colorful, more saturation would be more colorful. In today’s photography, desaturating a photo on the computer will gradually make it less and less colorful; and full desaturation would make it into a black and white photo.

Sharpness - See “Focus”

Summicron = Refers to the maximum lens aperture - here f/2.0 . There are many guesses how this name came about, a popular one being that the "summi" came from "summit" (summit means the highest point of a hill or mountain; the highest attainable level of achievement) while the "cron" came from "chroma" (ie. for colour). Not so: The name (Summi)cron was used because the lens used Crown glass for the first time, which Leitz bought from Chance Brothers in England. The first batch of lenses were named Summikron (Crown = Krone in Deutsch). The Summi(cron) is a development from the orignal Summar (the 50mm f2.0 lens anno 1933). Vario-Summicron is Leica Camera AG's name for zoom lenses f/2.0 as the one that is on the Leica Digilux 2.

Three-dimensional = Having the three dimensions of height, width and depth. In photography and lens design, three-dimensional effect is also the perception of even small micro-details; the texture of skin can appear flat and dead or three-dimensional and alive. Also, selective focus (foreground and background out of focus) can change the perception of depth. Also see Perspective.

Three-dimensional = Having the three dimensions of height, width and depth. Melrose Avenue in Los Angeles. Leica TL2 with Leica 35mm Summilux-TL ASPH f/1.4. © 2017 Thorsten Overgaard.

Vario- is the Leica Camera AG name for zoom lenses. Vario-Summicron is used for the lens on the Leica Digilux 1 as it is both a zoom, and a Summicron f/2.0 lens (see "Summicron").
