Tout… et un peu plus

Avec cette troisième déclinaison de l’Alpha 7r, Sony peut espérer toucher un public plus large: haute définition et hautes sensibilités sont toujours de la partie, mais l’appareil gagne en réactivité.

et aussi un dossier complet sur l’hybride et le reflex
Envie de switcher pour un hybride ?
Le switch est à la mode! Utilisateurs Canon ou Nikon, fatigués de porter du matériel trop lourd ou attirés par les promesses des appareils hybrides sont de plus en plus nombreux.
Mais si le switch offre quelques avantages, il présente aussi de très nombreux inconvénients et la course aux appareils allégés ne se termine pas toujours bien.
C’est pourquoi la rédaction fait un point le plus objectif possible sur les différentes solutions et sur la meilleure façon de switcher (ou pas!) au meilleur coût et, surtout, en fonction de l’usage prévu car c’est CE critère et lui seul qui devrait guider les utilisateurs.

Wide-Angle Zooms

Play the angles and get the big picture with an ultra-wide zoom lens.
With zoom ranges starting at just 8mm for APS-C format lenses, and 11mm for full-frame, you can shoehorn vast areas into the image frame. They’re great for shooting sweeping landscapes or architecture, and arguably even more useful when shooting indoors, where space is limited – but that’s just the start of the fun.

A key attraction of ultra-wide lenses is that you can create images with extraordinary perspective effects. Get in close to the main subject in a scene and you can massively exaggerate its relative size, against a shrunken, receding background. Parallel lines appear to converge at alarming rates and shots generally have a proper wow factor. Another bonus is that short focal lengths equate to huge depths of feld. Unlike portraiture, where it’s often favourable to blur the background, wide-angle lenses enable you to keep very close subjects and the distant horizon simultaneously sharp.

Barrel distortion can also add to the creative effect, especially when using wide-angle zooms at or near their shortest focal length. That said, all of the lenses in this test group are ‘rectilinear’, aiming to keep distortions to a minimum. The alternative is a fsheye or ‘curvilinear’ lens, which give even greater viewing angles but with more barrel distortion.

Super-Telephoto Zooms: Canon vs Fujifilm vs Nikon vs Pentax vs Sigma vs Sony vs Tamron

Whether you’re shooting sports, wildlife or something else altogether, sometimes a standard telephoto zoom lens just can’t get you close enough to the action. A supertelephoto zoom lens will extend your reach signifcantly – and there are plenty to choose from.

A zoom range of around 100-400mm has long been a popular option to include in lens ranges (there are four included here), but some manufacturers have been pushing the envelope, super-sizing focal lengths to as much as 600mm.

Apart from the Fujiflm X-mount lens, all of the contenders in this group are fully compatible with both full-frame and cropsensor cameras. Naturally if you fit them to an APS-C format camera, you can extend your effective reach even further, with a 1.5x multiplication effect (1.6x for Canon cameras). Typical attractions include fast autofocus systems and optical image stabilisation, but there can be notable differences in features and performance. Let’s take a look at what’s on offer…
