Focallength

The smaller the millimeter number (the shorter the focal length), the wider your field of view. The larger the millimeter number (which denotes that the focal length is longer), the more narrow your field of view.

The production A290 was unveiled on June 13, 2024 before the 24 Hours of Le Mans.[29] The design is identical to the concept. the base GT Premium is powered by a 130 kW (180 hp) electric motor, while the more powerful GTS has a 160 kW (220 hp) electric motor from the Mégane E-Tech that accelerates to 100 km/h (62 mph) in 6.4 seconds. The battery has a capacity of 52 kWh and a range of 380 km (236 miles).

In March 2023, journalists had the opportunity to test a development mule of the production version, scheduled for a release in 2024.[11] 'Vehicle check' prototypes, using near-final bodies and chassis, were tested starting in July 2023. These prototypes also serve to test the production processes. Prior development prototypes used Clio bodies on the CMF-BEV platform.[12]

As the name suggests, these lenses have a very wide angle of view! Often used by real estate photographers and landscape photographers, these lenses can make small rooms look large and take the full epic landscape view.

According to Renault Executive Vice President for Engineering Gilles le Borgne, the Renault 5 EV is expected to be priced starting from €20–25,000; options will include one of two battery packs (40 kWh or 52 kWh), with an expected range of 400 km (250 mi) using the latter.[3] The battery is expected to use NMC chemistry.[17] DC fast charging will be an added-cost option, and should match the maximum rate (130 kW) of the Renault Mégane E-Tech.[3] The charging port is mounted on the bonnet, behind a door just in front of the driver on the left-hand side designed to resemble the air intake on the original R5.[20]: 66

Some like the cool perspective distortion caused by wide-angle lenses, so they will capture their subjects with this angle in mind!

Technically telephoto lenses are distortion lenses, but not in the way you may think. They do not distort the proportions of your subject. The distortion is the fact that you can zoom in closer than your eye can see naturally.

However, they do have their downsides. Unfortunately, due to the zooming mechanism required to make the lens work, sometimes features are sacrificed to accommodate this. One such feature is very wide apertures. Zoom lenses have the widest aperture point of f/2.8, which is relatively shallow but not as shallow as f/1.8. This also increases the price tag exponentially.

Wide-angle lenses are not quite as wide as the ultra wides but are still quite wide. Why these lenses may be favored over the ultras is due to their reduced distortion – the glass isn’t as curved!

Just kidding, finances will often stifle your pursuit of many lenses. However, if you are to ask the experts, the correct answer to this question would be at least one of each focal length type. One ultra wide angle, one wide angle, one standard, and so on. This is because one lens cannot do it all.

In October 2022, Renault unveiled its "industrial metaverse" at the Flins plant in Yvelines, which is being transformed to become the Re-Factory.[9] Among the technologies on display was a simulation of a virtual reality paint booth, with the vehicle rendered in 3D for the demonstration being the production version of the Renault 5 EV, the first time it has been shown without camouflage.[10]

The Turbo 3E is 4,000 mm (157.5 in) long, 2,000 mm (78.7 in) wide, and 1,320 mm (52.0 in) tall, with a wheelbase of 2,540 mm (100.0 in) on a tubular chassis with a carbon fibre body and a combined output of 280 kW (380 hp) / 700 N⋅m (520 lbf⋅ft) using two electric traction motors, one for each rear wheel.[35] The battery has a storage capacity of 42 kWh.[36] The chassis is a FIA-compliant steel spaceframe.[37] The total weight of the car is 1,500 kg (3,307 lb), of which slightly more than 1⁄3 is the battery, at 520 kg (1,146 lb).[38]

Aperture

The focal length is denoted by -number- mm (millimeter) in both the name of the lens and on the lens itself. Contrary to popular belief, this length is not the physical size of the lens but rather the distance between your subject (or what you are photographing) and the point at which your camera can take a sharp photograph of the subject. So, the distance between your glass and its focus. That is why the same focal length between brands can have different lens sizes. For example, the 50mm lens can be a tiny and thin lens or a very long and bulky one.

On 9 May 2023, Alpine unveiled the A290_β, a concept car that previews the production model.[25][26][27] However, before the official debut, two photos of the model were accidentally leaked online.[28]

Zoom lenses offer a lot of adaptability due to being able to adjust the frame by simply zooming in and out, preventing you from needing to move physically. These lenses can change their focal length in a split second, allowing you to capture spontaneous moments. Zoom lenses are great for traveling because you’ll only need one lens on vacation.

However, these are the most expensive and heavy lenses on the market and often need a monopod or tripod (you won’t be able to handhold them for very long!).

The initial design was sketched by François Leboine; when Luca de Meo joined the company in July 2020 from Fiat, where he had overseen the launch of the Fiat 500 (2007), de Meo saw the possibilities of a revived R5.[22] The exterior of the R5 Prototype was designed by Nicolas Jardin.[20]: 64  Although the R5 Prototype is a five-door hatch, the rear door handles are hidden to be reminiscent of the original R5 of 1972 which was available as a three-door hatch and as a five-door from 1979.[20]: 69

Wildlife photographers capture animals with telephoto lenses, requiring them to sit further away from the subject and sneak around with their big lenses.

This is why buying a lens with an image stabilization system is a good idea! Each camera brand has its own version of an image stabilization system, so their lenses are denoted differently. Canon adds “IS” to the end of the lens names to specify that this system exists in the lens, Nikon adds “VR,” Sony adds “OSS,” and so forth.

Equally, having at least one fixed lens with a wide aperture can be vital, and at least one zoom lens with a long-range gives you flexibility.

Development of the Renault 5 E-Tech began from an orange life-size design mockup that was presented to Renault CEO Luca de Meo at the Renault Technocentre in Guyancourt in July 2020. The mockup was merely an exploratory study by a designer, François Leboine for a small electric car that was rejected as the company was not looking to produce a retro car. The mockup caught the attention of De Meo, which asked the design team to turn it into a prototype car. By October 2020, the prototype was completed. The prototype was showcased as the Renault 5 Prototype, and became a symbol of Renault's electric car strategy called Renaulution, which was announced on 14 January 2021.[2]

Zoom lenses may not always be as sharp as lenses that cannot zoom and often have softness around the picture’s edges. This isn’t a big deal to most, but it is something to remember.

The lens is what gives your image its final appearance. Although the camera houses the sensor, the autofocus motor, and other vital working components – it plays a relatively minimal role in what your photograph looks like.

If you have to settle on just one lens, pick the one that would work for the majority of photo shoots that you do daily.

The R5 prototype uses a small battery electric variant of the Renault–Nissan Common Module Family platform, initially designated CMF–B EV and later named AmpR Small.[3] CMF–B EV will be used in additional forthcoming small cars, including an electric version of a revived Renault 4.[14] Renault initially denied the 5 EV would replace the Zoe,[15] but later reversed their stance.[16] Standardization of the platform and battery technology is expected to reduce production costs by 33% compared to the Zoe, as many components are reused from the CMF-B platform used in the Clio V.[17] The Renault 5 EV will share its platform with the upcoming Nissan Micra EV.[18]

The focal length is a lens description that tells you what angle of view and magnification you can capture. The angle of view is how much or how little you can see in your picture. For example, a wide field of view will show you more of the frame than a narrow field of view.

The focal length you settle upon for each photo shoot will directly affect how you photograph and your personal aesthetic.

Fixed lenses have much wider apertures than zoom lenses. As mentioned in the Aperture Explained article, wide apertures lend a hand in photographing in very low light and producing beautiful shallow depths of field. Generally speaking, variable focal lengths can only hold an aperture at a width of 2.8 at its widest, while fixed focal lengths can go down as low as f/0.95!

Variable focal length is a fancy term for lenses that can zoom. These lenses can adjust their focal length by turning the zooming ring on the barrel. These lenses are very popular amongst photographers due to their versatility!

An Alpine-branded high-performance variant is planned, and will use the more powerful traction motor from the Mégane E-Tech, which is rated at 160 kW (210 hp). The Alpine variant is expected to retain the front-motor, front-wheel drive layout of the Renault 5 E-Tech, but the track will be wider for a sportier look.[24]

There is another factor to consider when using longer focal lengths that most don’t think about until faced with such a problem. Image shake describes the blurriness or shakiness you may see in your photograph. This happens because of the vibration caused by clicking on the camera’s shutter button to capture an image. Longer focal lengths, such as telephoto lenses, are prone to this problem.

Variable focal lengths, such as the 70mm – 200mm lens, will be denoted by their minimum and maximum zoom. Its widest point is 70mm, and its narrowest is 200mm.

In this guide, I will explain what focal length and camera zoom are, so you can understand how to use them to create stunning photos.

However, ultra-wide angle lenses require the glass to be curved to capture such a wide view and as a result, can cause a fishbowl effect when photographing something too close to the glass. Some love this look and have come to make the fisheye lens popular!

Your optics will affect perspective, field of view, and depth of field, all of which come down to the lens focal length – the little millimeter reading on the barrel!

Wide-angle lenses are used a lot by family photographers capturing large groups and by real estate and landscape photographers looking for something with less distortion.

Wide-angle lenses have the advantage of a close focusing distance, which means that the subject can be very close to the glass, and the lens can still focus sharply.

Because there are so many focal lengths, they are classified into different categories. These categories are (from the widest angle of view to the most narrow) ultra-wide angle lenses, wide angle lenses, standard lenses, telephoto lenses, and super telephoto lenses.

The Renault 5 E-Tech will be produced at Renault ElectriCity,[17] formed from the Douai, Maubeuge, and Ruitz factories in northern France;[23] assembly will occur at Douai, using components built at Ruitz and a motor from Cléon.[21] The pre-production prototypes of the R5 were built in the Technocentre facility near Paris that imitates the manufacturing process of the regular factories. Over 60 units of the R5 were built for testing and validation purposes before large-scale production commences.[18]

Standard lenses are incredibly versatile and are used for all kinds of photography. These lenses are also commonly seen with wide apertures. This allows photographers to isolate the subject from the background by blurring the background away.

Fixed focal lengths, also called prime lenses, do not zoom. The focal length they are set to cannot change. Newer photographs find the idea of a lens that cannot zoom odd and impractical, but prime lenses are prevalent in the industry for a reason!

To prove how much of a problem camera shake is for longer focal lengths, you’ll usually only see a stabilization option in longer lengths. Shorter lengths don’t tend to have this feature because it isn’t really necessary.

How much is cropped depends on the crop sensor’s ‘multiplier,’ which can differ between brands. How this works is that you take the full frame focal length (for example, a 50mm standard lens) and multiply it by the multiplier (for Nikon crop sensors, the multiplier is 1.5x), which produces the focal length a crop sensor will capture (in this case, 75mm).

Focus distance

The technical definition of focal length is a bit more complex than the above definition, but you don’t need to overcomplicate as a photographer. We are not lens engineers!

How this pertains to focal length is if you use a full frame lens on a crop sensor camera, your focal length will change. Focal length measurement is based on a 35mm field of view. If you’re using an APS-C camera, you’re cropping out the edges of that frame. As such, your full-frame lens will now have its focal length cropped.

Super telephoto lenses can zoom to extreme lengths of 300mm and beyond. These are epic for wildlife photographers that capture dangerous animals, such as big cats and bears. Wildlife photographers that capture birds high up in the trees also favor the super telephoto.

As if focal lengths weren’t made up of enough components, your camera’s sensor size plays a role too. Generally, cameras come in two sensor sizes: full frame camera or crop sensor camera (marked as APS-C). As such, lenses also come in two types: full frame and APS-C.

Fixed lenses’ benefits are their sharpness, quality, and wide apertures. Because prime lenses do not zoom, their barrels aren’t over-encumbered with zooming mechanisms. The lens is perfectly built for its exact focal length. As such, these lenses tend to be exponentially sharper than lenses that zoom! This also allows the lens engineers to focus on other key features (such as aperture) rather than ensuring the zooming barrel works well.

A sporty restomod version of the Renault 5 Turbo, dubbed the Renault R5 Turbo 3E and inspired by the 5 Turbo and Turbo 2,[32] was unveiled at the Chantilly Concours d'Elegance [fr] on September 25, 2022,[33] also being present at the 2022 Paris Motor Show in October.[32] The car was developed and built by Ligier with input from Yvan Muller.[34]

Crop sensor, as the name implies, crops your field of view because the sensor is smaller. So as you can imagine, the two lens types correlate with the two camera sensor sizes. However, you can use a full-frame lens on a crop-sensor camera just fine (but you cannot use a crop-sensor lens on a full-frame camera because the sensor is too big).

However, these do not have close focusing distances and require you to sit a reasonable distance from your subject. These lenses are also quite large, so be prepared for an arm workout.

The Renault 5 E-Tech is a B-segment battery electric car by French manufacturer Renault that will begin production in 2024. Inspired by the original Renault 5 in styling,[5] the 5 E-Tech was previewed by a concept car shown in January 2021,[6] with the production model being officially unveiled at the Geneva International Motor Show in February 2024.[7]

An electric Renault 5 was announced in January 2021 as part of Groupe Renault's strategic plan "Renaulution" covering the period 2021–2025+; the Renault marque has branded their effort "Nouvelle Vague" (New Wave), with the goal of offering the most complete electrified and hydrogen fuel cell lineup by 2025.[13]

In his short memoir about the Renault 5, De Meo emphasized the need of having at least one model that "express their DNA more than any of the others", citing the Fiat 500, Volkswagen Golf, Mercedes-Benz S-Class and Renault Twingo as examples. De Meo personally oversaw the development and organized intense critical discussions that led to some design changes, with an employee calling the car the "boss's car" that they "couldn’t afford to make mistakes".[2]

Telephoto lenses are long lenses that can remind you of a bit of a telescope. These lenses can zoom you very close to your subject! Used most by animal and sports photographers, telephoto lenses allow you to sit far back and capture subjects as if right next to them.

Although each brand has its patented stabilization technology, generally speaking, this system works because the components are set on a gimbal inside the lens that counteracts any movement – keeping all of the elements at level.

The R5 Diamant is a one-off vehicle that uses the original R5 body panels and silhouette with detail updates, such as protruding headlights and taillights providing a jewel-like look. It was styled by Pierre Gonalons, who stated his goal was to "merge automotive codes with those of interior decoration". The Diamant will be auctioned in fall 2022, with proceeds to benefit Give Me 5.[31] Details on the powertrain were not released.[30]

Standard lenses are amongst the easiest ones to work with because they feature no distortion (the glass is flat). Standard lenses are the closest to the human eye and what you see, which makes these millimeters popular choices for new photographers (much easier to photograph when you don’t need to account for perspective distortion problems).

As part of Renault's 50th anniversary celebrations of the original R5 in 2022, the manufacturer presented two "electromods": restomods of the original R5, repowered with electric drivetrains. These were similar conceptually to contemporaneous electrified restomods such as the Hyundai Heritage Series and Ford F-100 Eluminator.[30]

The downsides of fixed lenses are their lack of versatility and cost. Because the focal length cannot change, you have to move to alter the composition physically. This can sometimes be a burden depending on what you’re photographing. Prime lenses can also be more expensive than zoom lenses due to their overall increase in quality.

Because there is no zooming mechanism, these lenses have the potential to be lighter and smaller than variable focal length lenses.

Renault had to drastically reduce the normal development time for the Renault 5 from four years to three years, which it achieved by using the CMF-B platform as the base.[8] Around 1,100 parts was used to build the vehicle,[2] many of which are shared with other CMF-B vehicles such as the Clio V. The platform is also used by the Renault 4.[2]

Styling was performed by a team under the leadership of Gilles Vidal. It was inspired by the legacy Renault 5 model, with updates influenced by contemporary consumer electronics, furniture, and sports products.[19] Vidal joined Renault in November 2020, after the design of the R5 Prototype was already under way.[20]: 66  The double-diamond Renault logo, which was designed by Victor Vasarely and his son Jean-Pierre (aka Yvaral) and debuted with the original R5 in 1972, was illuminated and updated for the R5 EV prototype.[21] Work on the new logo predated the car, under a contract awarded to Landor & Fitch in 2019. The revised logo is scheduled to be deployed across the Renault range by 2020.[20]: 43
