Quel objectif pour le portrait?

Un portrait ? Avant de choisir un objectif, il est d’abord important de définir ce qu’on entend par portrait (en dehors du sujet lui même — on photographie bien évidemment une ou plusieurs personnes !). Il faut en effet définir comment le personnage sera cadré.

On distingue généralement cinq types de cadrages pour le portrait : le cadrage “en pied” (la personne est photographiée en entier, de la tête aux pieds, ce qui est parfois le cas en photo de mode), en “plan américain” (le modèle est coupé approximativement à mi-cuisse), en “plan taille” (le bas de l’image correspond aux hanches du sujet), en “plan buste” (tête et buste) et en “plan serré” (le visage uniquement).

The Lens: A Practical Guide for the Creative Photographer

Which lens should I buy for my camera?
It’s such a simple question, but choosing the right lens or lenses is actually one of the most important photographic decisions you can make. Nothing affects the quality of a photo more than the lens. It’s no longer just about the megapixels-it’s the glass that makes all the difference!
Many first-time buyers of DSLRs don’t venture past the basic lens included in the box. While some are reluctant to spend more money, others are confused by all the buzzwords or are overwhelmed by all the choices out there. It’s really a shame, because interchangeable lenses give you amazing scope for quality photography.

Take in vast sweeping scenes with a wide angle lens. Capture faraway birds with a telephoto lens. Examine the tiniest detail of a flower with a macro lens. Record the perfect portrait with a prime lens. Anything is possible when you choose the right lens for the job!
This book isn’t a simple catalogue of available lenses. New products are coming out all the time, and comparing specific lenses can be difficult. Instead, author N.K. Guy gives you all the information you need to make smart buying decisions. Optical technology is demystified, arcane terminology is decoded, and practical tips are provided.
The Lens will help you build the perfect lens collection to suit your needs-now and in the future.

Archer. This shot was illuminated solely by the two flaming light sources. A very fast lens set to f/1.2 was used, so the depth of field was extremely shallow. Highbury, London, England. 85mm full frame. f/1.2, 1/8 sec. ISO 200.

Meoto Iwa, the Wedded Rocks. A heavy rice straw rope links these two small near-shore rocks, representing the sacred bond of marriage. This is cool, but I have to say the woman rock is really unfairly small.Futami, Mie, Japan. In order to transform the ocean waves into a ghostly haze, an 8x neutral density filter was used along with a very low ISO and a tiny lens aperture. This allowed a comparatively long exposure of 20 seconds in full daylight. 50mm full frame. f/22, 20 sec. ISO 50.

Valentine Cave is a lava tube formed over 30,000 years ago. Flows of molten lava created hollow tube-like caves when the surface crusted over while lava continued to flow below.

Test du NIKON AF-S 500 mm f/5,6E PF ED VR

Ce 500 mm à lentille de Fresnel est gros comme un zoom 70-200 mm f/2,8. Il affiche de belles performances et un tarif étonnant — au bon sens du terme. À 4000 €, la facture est lourde, mais on pouvait craindre pire, les prix ayant tendance à s’envoler en ce moment, toutes marques confondues.

Nikon AF-P DX 10-20mm f/4.5-5.6G VR Review

Now you can get a Nikon-branded super-wide zoom for the same price as a third-party lens.
On paper, the Nikon AF-P DX 10-20mm f/4.5-5.6G VR has a few things stacked against it, but as soon as you use it, its small size, light weight and simplicity are instantly appealing. Serious enthusiasts might not be impressed, but its a brilliant buy for newer D3000- and D5000-series users.

Sigma DG 100-400mm f/5-6,3 OS HSM Contemporary au banc d’essai… et face à certains concurrents.

Le catalogue Sigma est bien fourni en longs télézooms, mais le glissement vers les très longues focales (600mm) laisse une place pour un objectif plus raisonnable. En lançant le 100-400mm, Sigma comble ce vide.

kerlee35aKerlee 35mm f/1.2 by dzoptics
The Kerlee 35mm f/1.2 lens by DZOptics was the fastest 35mm full frame lens when it was launched earlier in 2016. It’s a very fast, manual focus lens that boasts outstanding sharpness and soft bokeh at wider apertures. Available in Canon EF, Nikon F, Sony E and Pentax K mount, the lens can also be used on APS-C cameras as well as the full frame model it was designed for.

kerlee35bKerlee is a sub-brand of DZOptics technology co., Ltd. Kerlee’s name originates from the phonetic sound of ‘clear’ – a rather fitting name when you think about the quality of images that this lens produces. The aim was to develop an affordable yet high-quality lens that even amateur photographers could afford, using the best optics available. This, the first lens under the Kerlee name, has been designed specifically with photography enthusiasts in mind.

… Ce 200-500mm Nikon est très performant, il ne lui manque que quelques petits raffinements ergonomiques à glaner sur les concurrents, comme le système de verrouillage des focales des Sigma. Lui ne dispose que du verrouillage à la focale la plus courte pour faciliter le transport …
