Where Sharpness and Softness Coexist

FíRIN is a variation of Fírinne, the Old Irish word for “truth”, which was coined during the Gaelic Revival in the late 19th Century. It means, “that which is real”. It signifies “being true to someone or something”. And it represents a promise from Tokina to photographers to help them capture the truth in their images with this revolutionary new lens.

With FíRIN, photographers can shoot with confidence, knowing that every image captured with their mirrorless cameras will be its own moment of truth.

Le Sony FE 200-600mm f/5,6-6,3 G OSS | Test Chasseur d’Images

Le Sony FE 200-600mm f/5,6-6,3 G OSS | Test Chasseur d’Images
Ce télézoom extrême, plus long que le FE 100-400 mm, permet à Sony de prendre encore de l’avance sur les concurrents (Canon et Nikon), en augmentant son offre d’objectifs en monture directe. Pour les EOS R et les Nikon Z, il faut passer par une bague de conversion.
Sony a fait le choix d’un objectif dont la longueur ne varie pas avec la focale. Les quelque 25 mm gagnés grâce à la monture courte pour hybride le permettent. La prise en main est bonne et l’agrément d’utilisation au rendez-vous — avec les boîtiers Alpha 7, un peu moins avec un Alpha à capteur APS-C. Pour améliorer encore ce point, on peut visser sous l’appareil une poignée accessoire. Elle facilite le cadrage en vertical.
L’objectif est vraiment bien construit. Les boutons fonctions et les réglages fins de la stabilisation et de la distance de mise au point sont autant d’atouts…

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.

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.
