Despite their appearance of reflex, bridges rely on compact cameras with a fixed lens technology. Bulkier, heavier, but also more ergonomic compact, these cameras are aimed above all lovers warned looking for a functional and versatile device.
Digital cameras comparison bridge
Even if they are on the decline in recent years, bridges (‘bridge’ in English) continue to seduce some amateur photographers. Their main asset, it is their case imposing which improves the grip and allows fingers to position naturally on the keys. Many features are available easily thanks
to the presence of buttons and knobs. If the user has the opportunity to play on some settings (aperture, shutter speed, white balance, focus, etc.) to improve the shot, it can also hide behind the automatic mode. Finally, the bridges are characterised by their powerful zoom and the presence of an electronic viewfinder. As their performance, they are closer to those of the Compact as those of SLRs.
A Versatile Zoom
One of the peculiarities of the bridges, it’s their powerful zoom. Some go to ship goals 50 x or more that allow to take as well pictures of landscape as portraits, even when the subject is far away. If the manufacturers tend to highlight flattering their digital zoom performance, rely only on the optical zoom, which preserves the details of the image. Also be aware that a big zoom must necessarily be accompanied by a good optical image stabilizer, otherwise you may have difficulty to frame the subject and don’t get blurry pictures. A tripod may be useful in some cases. Finally, beyond the magnification ratio, also look at the focal range covered by the objective and, in particular, the minimum focal length. A minimum focal length of 28 mm or less allows to benefit from a wide angle, useful for shooting landscapes or groups of people indoors.
A Height Sensor
The resolution of the sensor is no longer a decisive selection criterion: it has now reached levels sufficient largely to a common use. On the bridges, the average is between 12 and 20 mpixel, print without problem to format 21 × 29.7 cm or more in maximum quality and crop his pictures on a part of the image. In fact, more than the resolution, check especially the actual size of the sensor. More it is great, more it is able to store light and so more photos are likely to be light. This is expressed in millimeters or inches fraction (a 1/2.5 inch sensor is smaller than a 1/1.6 sensor inches, for example). Unfortunately, this information is not always provided by the manufacturers.
A Wide Screen
The screen is big, more shooting is easy and more enjoyable are navigation in the menus and viewing of photos taken. But beyond the size, he must also consider his resolution, contrast and its ability to limit the appearance of reflections. On the other hand, prefer him multidirectional, vertically and horizontally. This will facilitate the framing and you can multiply the original angles. Finally, a touchscreen would facilitate navigation in the menus and will allow you to scroll through the photos with a simple swipe of a finger and even to the development of a simple click on the topic, as on a smartphone.
A High-Performance Viewfinder
Most of the bridges are equipped with a viewfinder, but unlike those of SLRs, it’s electronic. The image that we see comes from a LCD or OLED screen. Therefore, the quality can be highly variable depending on the model. So check its resolution, its size and if possible its reactivity (an effect of latency may indeed intervene when the subject is moving).
A Sensitivity To The Top
The sensitivity determines the relationship between the aperture and the shutter speed for a given lighting and is measured in ISO. It is high, the more the device will be able to store light and so to take pictures in low light or conditions when the subject is moving. Some bridges show sensitivities up to 6 400 or even ISO 12,800. However, better do not expect miracles because the high sensitivities tend to generate “noise” (of parasites on the image). To reduce this phenomenon, devices incorporate noise reducers more or less effective and often destructive of details.
If most of the bridges include the wi – fi, all do benefit from this in the same way wireless connection. With some, it serves mostly to connect the camera to a smartphone to trigger the shooting from an application or transfer pictures taken on his phone. With others, the wi – fi is also used to transfer his photos on his computer or to a storage online (cloud), to send the photo to a printer or on a television connected to the same network. It can also be used to send photos directly from the camera by e-mail or on social networks. Some devices incorporate even a browser to perform searches on the internet directly on the screen of his camera. The best thing is that he is accompanied by the NFC. Then just close the camera of the smartphone for the pair.
Batteries Or Battery, Please Choose
If battery power limits the risk of run out of energy, especially during long trips, most of the devices now include a battery rechargeable, cheaper to use. To avoid ending up short of energy, it may be appropriate to acquire a second battery and an independent magazine.
Small ‘Plus’ Of Bridge
The flash shoe
Use an external flash can be useful for the lack of power and uniformity of the built-in flash. In this case, check that the appliance is equipped with a claw that is able to accommodate a.
A fast burst mode
To take pictures of moving subjects, at sporting events, for example, photographing several images in a row automatically multiplies the chances to succeed his photos. Burst mode is measured in number of frames per second. It is usually around 4 or 6, but some devices offer up to 10 images per second or more.
In RAW format recording
This gross recording format is popular with those who want to retouch the colors or the exhibition of their photographs on computer before saving them in a readable (in for example .jpg) format. This method also allows to save selected settings to apply to multiple images. The consideration: the RAW files are very large, making it necessary to use high capacity memory cards.
With it, you can take movies in high definition. But to take full advantage, you must also have a powerful computer and a TV 4K (or UHD).
