The Leica D-Lux 8 is an advanced zoom compact camera that’s designed for enthusiast photographers. It’s a development of the Leica D-Lux 7 from 2018, which itself was a re-styled version of the Panasonic Lumix LX100 II. The D-Lux 8 has the same lens, sensor, and core specifications as its predecessor, but it gains a radically reworked control layout based on the Leica Q3, along with a much better viewfinder. All the ingredients are in place for it to be one of the best compact cameras around.Leica D-Lux 8 at a glance:$1595 / £145024-75mm equivalent f/1.7-2.8 lens with OIS17MP Four Thirds multi aspect-ratio sensorISO 100-25,000Up to 11fps shooting2.36m-dot, 0.74x OLED viewfinder3in, 1.84m-dot LCD touchscreen 4K 30p video recordingIt’s no secret that the ever-increasing quality of smartphone cameras has decimated the market for traditional compact cameras. But there’s one standout exception at the top of the market, in the shape of Fujifilm’s classically-styled and wildly popular X100VI. With the D-Lux 8, Leica is clearly hoping to grab a piece of the action with a camera that shares many of the same attractions, but which has a zoom lens. Like the X100VI, the D-Lux 8 has traditional photographer-friendly controls for the main exposure settings, plus a corner-mounted viewfinder in a flat-bodied ‘rangefinder-style’ design. But in contrast, it employs a smaller Four Thirds type sensor with a clever multi-aspect ratio design, joined by a 24-75mm equivalent zoom with a bright f/1.7-2.8 aperture. It’s in much the same price bracket as the X100VI, at

D-Lux 8 is, mostly, a joy to shoot with. It’s a camera where you feel that you’re in control of what it’s doing, rather than at the mercy of its automated systems. The zoom lever provides precise control over composition, which isn’t always the case with compact cameras, and it’s easy to change the main exposure settings with the camera up to your eye. Lens controls are essentially the same as before. You get a traditional aperture ring, which clicks in one-third stop steps from f/1.7 to f/16. Of course, if you set the ring to f/1.7 and zoom in, you’re still limited by the lens’s maximum aperture: f/2 at 28mm, f/2.3 at 35mm, and f/2.7 at 50mm. There’s also a dedicated manual focus ring, plus switches for focus mode (auto, macro, and manual) and aspect ratio.As for the top-plate controls, there’s still a shutter speed dial, plus a conventional zoom lever around the shutter button. But otherwise, it’s a case of all change. Where the D-Lux 7 had a dedicated exposure compensation dial, there’s now an electronic dial with a button in its centre, just like the Q3. I set the dial up to adjust exposure compensation and the button for ISO, which gave me direct control of all the key exposure settings.Rear controls have been dramatically simplified too, to just a d-pad and four buttons. The directional keys are used to position the focus area, while the button in their middle cycles through display modes that show different

Is often used in offices, kitchens and bathrooms.What is LUX?Lux is the calculated average light value of the area the light source have to shine on with it's given lumen rating. In short lumen divided by area in m². If you have a light with 4lm (lumen) that shines on 1m² (1m * 1m) the result would be 4 lux. But if the light shines on a room that is 2m * 2m the area is 4m², and the result would be 1 lux. Examples of lux levels: Bright sunlight 100.000 lux, Overcast day ~1000 lux, Office lighting/kitchen 250-500 lux, living room 100-250 luxPAR vs PPFDPAR refers to the range of light wavelengths (400-700 nm) that plants use for photosynthesis. It is a measure of the light spectrum that plants can absorb and use for growth.PPFD is a measure of the amount of PAR that actually reaches a surface, like a plant canopy. It represents the intensity of photons within the PAR range that hits a square meter every second and is measured in µmol/m²/s.MythsIncandescent light is just as good as any other light.Yes, in fact the light from an incandescent light source does work, it still gives of light a plant can use. However, this type of light is based on heating a filament to the given kelvin rating, i.e., 2700k = 2426°C / 4399°F so this type of light gives of much more heat(infrared) than light, and is a poor choice for a grow light. As much as 90% of the power used is given off as heat instead of light, this is about the opposite of LED that turns up to 90% of the energy used into usable visible light and only 10% as heat, additionally LED can be produced to give off certain wavelengths of light.RED and BLUE (blurple) LED light is bestYou might have heard that blue and red LED(light emitting diode) in specific spectrum is all you need, but tests have shown, especially for taller plant that the green spectrum seems to penetrate further down in the canopy of plants, so that using only these red and blue(blurple) LED is not as good as full daylight, especially for taller plants. Not to mention you get totally weird in the head by looking at them.However, having extra blue and red LED can indeed increase the PAR(photosyntetic active radiation) light used by plants, while including warm(3000K)
