Q2: Features 47.3MP Full-Frame Sensor
It does not take a genius to work out that the Leica Q2 is a follow-on from the Leica Q. Like the original Q, the Leica Q2 (Type 4889) is a compact camera, which means it has a fixed lens. In both cases, at 28mm f / 1.7 optic. However, unlike most compact cameras, the Q and Q2 have full-frame sensors. Whereas the Leica Q (Typ 116) has a 24.2Mp sensor, the Leica Q2 has a 47.3-million-effective-pixel sensor. That's the most significant difference between the two cameras, but there are a few other changes here and there.
Despite looking at a small M camera, complete with traditional exposure controls, the Q2 can focus automatically and has an electronic viewfinder (EVF) built-in. In addition, the screen on the back of the camera is touch-sensitive.
Like the original Q, the Leica Q has superb build quality. The handling is also a delight and the images look great up to around ISO 6400. It's a dream compact camera. There was a time when the majority of compact cameras used 35mm film. Which means they were full-frame cameras. Making a full-frame digital compact camera is a bit more involved, so they're common and they're quite a bit more expensive. The Leica Q2 is set to retail for £ 4,250 (over $ 5000), for example, and the 42Mp Sony RX1R II has an RRP of £ 3,450 / $ 3,299.

The downside to a full-frame sensor is that the lens needs to be capable of producing a large circle image. And unlike with film, the structure of each pixel means that the angle of the light rays is important. If the light hits the sensor at an oblique angle there can be a serious loss of image quality toward the edges of the frame.
Leica Summilux 28mm f / 1.7 ASPH. Lens
Like the Q (Typ 116) the Leica Q2 (Type 4889) has a Leica Summilux 28 mm f / 1.7 ASPH lens. However, according to Leica, this has been tweaked for the Q2 to optimize it for use with the higher resolution sensor.
The 28mm focal length is a nice choice for everyday photography. However, there are crop settings that produce framing equivalent to 35mm, 50mm and 75mm. These result in 30.0Mp, 14.7Mp and 6.6Mp images respectively.
Unlike Leica's M cameras, the Q and Q2 can focus automatically. Leica has not changed from the Q's autofocus (AF) system to the Q2, it has the same 0.15sec response time. Like the Q, the Q2's lens has three rings. The aperture ring sits at the end closest to the front element. Behind it is the manual focus ring. This has a small lock that needs to be unlocked to enable manual focusing. Rotating the ring all the way to the furthest focusing point until it clicks, sets the lens back to autofocusing.
The ring closest to the camera body is to select Macro focusing. When this is selected, the minimum focus distance reduces from 30cm to 17cm.
Processing Engine
Leica has paired the Q2's 50.4Mp (47.3Mp effective pixel count) sensor with an updated version of its Maestro processing engine.
This enables the sensitivity range of ISO 50-50,000 and a maximum continuous shooting rate of 10fps (frames per second) in Continuous High Speed ​​mode or 20fps in Continuous Super Speed ​​mode. The latter uses the electronic shutter to enable faster speed. The focus is set at the start of the sequence. Shooting modes
Leica does not tend to go in for lots of fancy shooting modes, but as well as the enthusiast's favorite PASM exposure modes, the Q2 can shoot in Full Auto or one of 12 scene modes. These include Sport, Portrait, Landscape, Night Portrait, Snow / Beach, Fireworks, Candle Light, Sunset, Digiscoping, Miniature Effect, Panorama and HDR.
Images may be recorded as DNG raw files or Jpegs, or both simultaneously. The appearance of Jpegs can be set using the Film Style settings which are Standard, Vivid, Natural, Natural, monochrome and High-contrast monochrome. The contrast, saturation and sharpness settings of each of the color settings can be adjusted across 5 steps (Low, Medium Low, Medium, Medium high and High). The contrast and sharpness of Monochrome settings can be adjusted in the same way. Other Features
While the original Q can record MP4 Full-HD video at 30 or 60fps, the Q2 can be used to shoot 4K (3840 x 2160) video at 24 / 30fps or C4K 4096x 2160 at 24p. There's no port to connect an external mic (or headphones), so audio must be recorded via the built-in mic.
Optical image stabilization is built-in and can be set to automatically cut when the shutter speed drops to 1 / 60sec or slower.
In addition, both Wi-Fi and Bluetooth connectivity are built-in. The Bluetooth connectivity enables easier pairing with Leica's Photos and speeds connecting to the Wi-Fi system for image transfer and remote control. It also allows the camera to be woken up remotely and for the camera to be set to match the phone.
Helpfully, the Leica Photos app shows images on a black background if they're on the camera and white if they've been transferred to the phone. Build and Handling
Leica has made the Q2 the same shape as the original Q, but according to the specifications, it's a little shallower. The Q measures 130 x 80 x 93mm (WxHxD) whereas the Q2 is 130 x 80 x 91.9.
By popular demand, the Q2 is also weather and dust resistant to IP52 standard. That's good news given its a camera that's more likely to be used outside of a studio.
Leica lovers will approve of the 'made in Germany' inscription on the back. And nobody can fail to notice the high quality, durable feel that comes with it. You can tell it has a metal construction the moment you pick it up. The top plate is made from machined blocks of aluminum while the body is made of magnesium alloy. All the lettering and setting markings are laser-engraved.
A smooth indent on the back of the camera forms a thumb rest while the flat front of the Q2 has soft, textured coating that gives a little grip. The Q2 never slipped from my hand during the days that I shot it, but I would not dream of using it without some form of strap. It has the type of build that suggests it will survive to drop some ground, but you really do not really want to risk it.
A quick glance across the body of the Q2 reveals some small changes to the control layout in comparison with the Q. There are now three rectangular buttons to the left of the screen on the back of the camera, for example. These are marked Play, Fn and Menu. Menu
Leica has designed the Q2 to allow you to concentrate on the most important aspects of photography. That means the aim is to make it easy to adjust key features without having to use the menu too often or wade through loads of quirky features.
Pressing the Menu button reveals those features that you've signed to your 'Favorites'. These are selected via the Custom Control option on the 4th page of the main menu. You can assign up to 15 features to the Favorites menu but any more than 8 makes it overflow to a second screen. You can either access these options by scrolling down or by pressing the Menu button again. A third press of the menu button takes you to the point you were last in the main menu. Subsequent presses take you through each Menu page (1-5) in turn, excluding the Favorites page.
Both the shutter speed dial and the aperture ring have A for automatic settings. If both are set to A, the camera is in program exposure mode. If the aperture is set to A, the camera is in shutter priority mode and if the shutter speed is set to A, the Q2 is in aperture priority mode.

Thumb Wheel
By default, the thumb wheel can be used to adjust exposure compensation. If the shutter speed dial is set to 1+, however, exposure compensation is set via the main or function menu.
In addition, a long press the button at the center of the thumb wheel reveals up to 8 parameters that can be adjusted. A short press reveals the option for the selected setting. It's a clever way to be able to adjust two settings very quickly via one dial. And it only takes a fraction of a second longer to be able to adjust another 7 parameters.
The Fn (function) button works in a similar way. A long press reveals up to 8 features that can be adjusted. A short press shows the options for the selected feature.
Both of these lists are customizable via the main menu. Viewfinder and Screen
Although Leica has stuck with the same 3,680,000-pixel resolution for the electronic viewfinder (EVF), it's now an OLED device. It delivers a very detailed, smooth view and replicates the appearance of images very well.
On the back of the camera, there's a fixed 3-inch 1,040,000-dot TFT touchscreen. It also provides a clear view and a wide viewing angle, but it would be nice if it could be tilted.
The screen is generally responsive to touch, which is useful for setting the AF point or zooming in to check the sharpness of images.
Performance
It's a while since I shot the Leica Q, but it's one of my favorite cameras. The Leica Q2 is just as appealing.
The first thing that struck me about the images from the Q2 in its default settings is that the colors are quite muted by modern standards. I noticed it as soon as I put the camera to my eye and looked through the EVF. In some instances, the results look similar to those from a Fuji camera in Classic Chrome mode. That happens to be my favorite Fuji Film Simulation mode, so I'm quite happy about it.
If you want to give colors a bit more oomph, the Q2 has a Vivid Film Style. It works well without overcooking the saturation. The Monochrome options are also worth trying.
The Leica Summilux 28 mm f / 1.7 ASPH lens on the Q2 is a high-quality optic. Even when the aperture is wide open it captures an impressive amount detail and there is only the slightest fall off towards the corners. Closing the aperture to f / 2.8 gets the whole sharp frame.
Like the Q, the Q2 is not a camera that suffers from flare on a frequent basis. It's very well controlled. If you include the low sun in the frame you may spot a flare highlight, but you will not see a major drop in contrast. Image Quality
As you'd expect with a full-frame 47Mp sensor, the Q2is capable of capturing a lot of detail. At low-to-mid range sensitivity settings, it's very good. What's more, the detail looks very natural, even at 100% on-screen and in both raw files and Jpegs.
Noise is handled well at ISO 12,500. When images are sized to fill a 15-inch screen for example, there's just a hint of texture in the uniform tone areas of raw files. The same areas of simultaneously captured Jpegs look smooth but there is slight softening of the detail in those sections with the finest texture.
Zoom into 100% and the texture in the raw files becomes more obvious. However, it's uniform, with no clumping or banding. It's not offensive. Meanwhile, the Jpeg has just a suggestion of texture in some areas at 100%. And the trickiest areas, where fine details are out of focus are just the right side of being smudged. Jump up to ISO 25,000, however, and the balance swings in the wrong direction. Noise and its removal become more evident and some shadows have a magenta or purplish cast.
I recommend making ISO 12,500 the maximum setting. However, I noticed that when the sensitivity is set to Auto, the Q2 never goes above ISO 6,400, so it seems that is the maximum that Leica recommends. Autofocus
Although it is possible to focus manually with the Q2, there were no occasions when I felt the need for the few days I had the camera. Even in low light conditions, the AF system got the subject sharp. And in most cases in Single AF mode it does so quickly. In Continuous AF mode its prone to adjusting the focus unnecessarily, especially in low light. It's more stable when you're recording video.
The AF point selection mode can be set to Multi-Field, Spot, Field, Tracking or Face Detection.
Of these options, I find Spot and Field the most useful. Multi-Field leaves the camera to decide where to focus, and I prefer more control.
The Face Detection setting can be handy with people photos, but if you turn to shoot something else you need to change mode. Also, you can set the AF point with a tap on the screen on Spot, Field and Tracking, which is quick and easy. Then if you need to move it, you can use the navigation pad. There is no joystick or trackpad option with the Q2.
I find the Tracking AF setting useful in some situations. It allows you to set the AF point by tapping the screen but you can then adjust the composition and keep the subject sharp. It does not work with every subject so it's worth experimenting with it.
It's worth noting that the Q2's highlight alert is a little over-protective. It flashes when the highlights are getting close to burning out rather than actually burning out. In some cases, the difference is a whole stop or more.
I have a few landscape images where the highlight was flashing away in the sky, but I found it was not burned out. If you're not prepared for it, this may encourage you to underexpose a scene to protect the highlights unnecessarily.
However, the Q2 also has good dynamic range, so if you're shooting at a low sensitivity setting, dark images can withstand a fair degree of adjustment. I found it possible to make adjustments of around 4Ev without significant loss of detail or the introduction of noise becoming problematic. A 5Ev adjustment is a bit too much.
