Nikon Coolpix L320

Introduction

The Nikon Coolpix L320 is an easy to use long zoom compact camera. Shaped like a compact DSLR, the camera sports a large 26x optical zoom, 16 megapixel CCD sensor, 3 inch LCD screen, EXPEED C2 processor and takes AA batteries. Coupled with the wireless transfer via Eye-Fi memory cards and the L320 pans out to be a camera for the traveller or keen walker. Priced at around £190, the L320 is available in black.

Ease of Use

For those of you interested in the shape, feel and flexibility of a DSLR or large zoom prosumer camera, you'll be pleased to know that if you don't have the funds available for an expensive model, the Nikon Coolpix L320 is a budget version of other models in the “L” range. It's a smaller brother of the L820 but is pretty much a clone when it comes to the exterior. The L320 has a smaller zoom, reaching to a maximum 26x optical. That still offers you an ultra-wide 22.5mm before zooming out to a nail biting 585mm. Great for if you're walking out in the countryside and there's an interesting natural event that needs a picture, but it's too far away. The zoom is operated via the zoom switch found wrapped around the shutter release on the corner of the grip.  Behind this on the main top plate is a small power button. It's sunken into the body so as not to get caught by accident in the heat of the moment.
The idea behind the design of the large grip is to make it easier to hold and to shoot one handed.  The weight of the lens is nicely counter-balances the batteries so that the camera is balanced. All the main controls have been placed on the back of the camera and are easily accessible by the thumb that will naturally rest there. The video record button sits on the shoulder and this can be used regardless of whether you're taking pictures or not. In fact, the video mode has been removed from the camera because the video button made it redundant.

Should you want to choose a mode to take pictures in, this is done by pressing the green camera button on the back of the Nikon Coolpix L320.  A simple menu will come onto the screen and it allows you to choose from four shooting modes: Easy auto, Scenes, Smart portrait and Auto. The Easy auto mode is – essentially – an automated version of Auto mode. It takes all the decision making out of your hands while still ensuring the correct scene is selected. It does this by analysing the scene as you start to use the camera. It then selects the appropriate mode for the scene it's viewing. For example, it it locates a face, it'll assume you're taking a portrait. It will automatically switch into portrait mode, enable face detection and the flash (if it's in the up position).
The Scenes will allow you to take control of the situation you're in and choose the Scene you want to shoot in. There are 18 to choose from ranging from the typical landscape, portrait and sport modes to more niche options such as museum, panorama and backlit subject. Smart portrait mode utilises every mode and feature of the camera to ensure you get the best portraits such as face detection, blink detection, skin softening and red-eye fix. The final option is the general everyday mode to shoot in. It's useful if you don't want the camera to mess about or require something more routine.

The battery compartment is located on the bottom of the Nikon Coolpix L320 and blessedly has a locking switch. AA batteries tend to impose a degree of pressure on the battery door and it could spring open at an embarrassing moment if it didn't have the lock. We would have liked to see a metal tripod bush on a camera with such a long zoom lens so that you can select a low ISO in the Main menu and keep the noise down while using the zoom or shooting at night.
The Main menu can be accessed by pressing the Menu button on the back of the camera. There are three tabs on the left which you can access by pressing left on the navigation pad. This will flick through the camera, video and main Set-up menus. The Shoot menu, denoted by a green camera, has only five options to it and they all alter the immediate way the camera takes pictures. For example, you can change the resolution, white-balance or ISO. There's also an option for continuous shooting and various colour options such as Vivid, black & white, sepia and cyay Taboola 
Start up from cold is around 2.8sec which is slower than average of 2.5sec. However, we have to take our reflexes into consideration. The reason being that the shutter button can't be simply pressed down with the aim of taking a picture once switched on. The camera won't register the button being pressed if it's done before it's finished the start up cycle. Given that we have a reflex response time of around 0.4sec, that would take the camera to around the average speed for a start up time. We managed to get seven pictures in a 10 second time-frame which works out around 0.7fps (frames per second). The first four frames record in around 2.5 seconds, which is 0.6fps, not the 1.2fps that Nikon state on the website. We even tried dropping down to the standard resolution, but got similar results.

Press the Playback button and the most recent picture you took will come up on screen, full screen, for you to review. Basic details of the picture are flashed up on screen for a few seconds before they disappear to just the image. You can zoom in using the zoom switch and check sharpness of focus and you can also move around the picture using the navigation pad. Zooming out lays the pictures out as thumbnails for you to review multiple ones at once. In the Playback menu, you can alter the appearance of pictures using the many editing options available such as D-Lighting control, skin softening, rotation, protect and copy. There's also provision to create a slide-show.
In the box, you'll find some practical accessories for your camera such as a pack of batteries to get you started. The great news about batteries that are provided these days is that they're generally very good. Certainly the Nikon ones are. The pack we had lasted us the entire test and beyond. There's also a neck strap, lens cap and USB lead. You also get some software in the shape of Nikon View NX2. The full manual is also located on the disc, although it doesn't say so. However, given that there's only a Quick Start Guide in booklet form, it's common sense

NikonD7100

The enthusiast-targeted Nikon D7100 becomes the company's latest APS-C DSLR to feature a 24MP sensor, joining the D3200 and D5200 models that were announced in 2012. As the eagerly anticipated successor to the very popular two-and-a-half year old D7000, the D7100 faces a sizeable task. In our in-depth review we found its predcessor to combine very good image quality, class-leading noise performance and great handling in a solidly-built body.
Nikon appears to have taken this challenge to heart with the D7100 looking, on paper, like a very significant upgrade. The D7100 becomes the first Nikon DSLR to omit an optical low-pass filter (OLPF), a move we've seen rival Pentax take with its K-5 IIs. In theory, removing the OLPF altogether should result in a higher resolution than the filtered 24MP sensors found in the D5200 and D3200 can produce. We saw Nikon test the waters in this regard with the 36MP D800E, in which the effect of the OLPF was 'cancelled out'. Based on our test results with that camera, we suspect that realizing benefits of the OLPF's omission will require some very good optics at optimum apertures. The downside is, of course, greater potential for moiré-induced artifacts when shooting stills of objects with fine patterned detail.
Other D7100 upgrades over the D7000 include a significantly upgraded AF system, with focus algorithms borrowed from the top-end Nikon D4, 51 AF points (15 cross-type) and the stated ability to focus in light as low as -2EV. The D7100 gains a slightly larger 3.2-inch 1.2M dot rear LCD that features an RGBW display. The additional white dots allow the screen to either be run at lower power or noticeably brighter than the RGB panels found on previous Nikons for increased brightness or efficiency, depending on need. Owners of multiple Speedlights can also make use of Nikon's wireless remote operation (dubbed 'Advanced Wireless lighting') of up to three separate groups of flash units. And, as with the D7000, the camera's built-in flash can be used in Commander mode to trigger remote flashes.
The D7100's 24.1MP CMOS sensor does not include an optical low-pass filter (OLPF). While the flagship D800E had the effect of its OLPF 'cancelled out', this is the first time Nikon has done away with the filter altogether.
Video shooters get some upgrades as well. The D7100 offers 30p and 25p as well as 24p (rather than just 24p) recording and built-in stereo microphones. When using the D7100's optional 1.3X crop mode, which gives an effective focal length increase of 2X (a 50mm lens provides the crop of a 100mm), 50/60i movie recording is available. This crop mode also allows for 15MP stills capture at 7 versus the standard 6 frames per second.
The D7100 supports Nikon's WU-1a Wi-Fi unit, which plugs into the camera's accessory terminal and allows images to be transmitted wirelessly to a smartphone or tablet for uploading to social networks. The device also allows remote control of the camera from your smartphone, complete with live view, which can be a fun way of setting up self-portraits or group shots.
In a seemingly small, yet very practical upgrade over the D7000, the D7100 inherits the well-implemented Auto ISO program that we saw first on the D800, and later on the D5200. This allows the camera to set the minimum shutter speed automatically based on the focal length of the lens in use, with a choice of five user-controlled settings that bias towards faster or slower speeds. This fixes one of our biggest criticisms of earlier-model Nikon DSLRs, and obviously makes Auto ISO much more suitable for use with zoom lenses.

Compared to the Nikon D7000

Physically, the D7100 is very similar to its predecessor, with practically identical size and weight. Place the two cameras side by side in fact, and you'd need a moment to tell one from the other. With the exception of the new movie button on the top-plate and the addition of a fifth button along the left side of the camera, the key controls are almost identical, and fall in basically the same places. Most of the interesting bits of the upgrade are hidden away inside the D7100's magnesium-alloy and polycarbonate shell.
