Les arrangements d'OS pour l'objectif d'OS HSM de C.C f/3.8-5.6 du sigma 18-125mm sont simplement marche-arrêt. Même lorsque le commutateur d'OS est éteint, le bruit vrombissant léger indiquant l'OS fonctionne peut être entendu tandis que le mètre d'appareil-photo est en activité. Le sigma a énoncé à moi que des restes d'OS actifs pour tenir l'objectif en position optiquement centrée - et vous voyez le saut encadrant de viseur dans une nouvelle position quand le mètre est activé ou mis hors tension. Maintenez ceci dans l'esprit en encadrant votre projectile - particulièrement en installant un projectile trépied-basé (maintenez le mètre actif).

L'objectif d'OS HSM de C.C f/3.8-5.6 du sigma 18-125mm vient avec centre-et-côté-pincent le chapeau avant d'objectif il est facile obtenir qu'outre de même à l'intérieur du capot relativement petit aussi-inclus d'objectif. Un chapeau arrière est toujours inclus naturellement.

L'objectif d'OS HSM de C.C f/3.8-5.6 du sigma 18-125mm est disponible dans des bâtis de Canon (passé en revue), de Nikon, de sigma, de Pentax (aucun OS) et de Sony (aucun OS, aucun AF à moins que le corps soutienne le moteur de HSM). Ma renonciation aux normes obligatoire : Vous devriez savoir qu'il y a les questions potentielles avec des objectifs de tiers. Depuis des ingénieurs d'inverse de sigma (contre les routines d'AF de fabricant de permis), la possibilité existe qu'un nouveau corps ne pourrait pas soutenir un objectif plus ancien de tiers. Bien que non commun, ceci s'est produit. Parfois un objectif peut être rechipped pour être rendu compatible, parfois pas. En second lieu, il y a le risque d'un problème qui a comme conséquence les fabricants d'objectif et de corps dirigeant le blâme à l'un l'autre. Cependant,...

Le programme de la capture NX de Nikon a toujours été un choix plein pour ceux qui emploient le format CRU de dossier de NEF employé par des appareils-photo de Nikon. C'était la première application qui s'est servie de la technologie d'U-Point pour des choix qui est maintenant trouvée dans des produits de logiciel de Nik comme Viveza, Dfine, et connexions d'Efex de couleur pro pour Photoshop et ouverture. La capture NX combine les dispositifs de traitement CRUS puissants avec la bonne gestion de dossier. Le dernier dégagement de la capture NX, la version 2, a ajouté quelques nouveaux dispositifs puissants au mélange qui fera appel à Nikon et à photographes avec d'autres marques. Of course, the RAW editing features are NEF specific, but there are a number of other editing controls for JPG and TIFF files (sorry, no DNG import).

Ease of Use

At first glance, Capture NX 2 looks similar to the previous version, but there are useful changes waiting to be explored. You now have the flexibility to configure and save custom workspaces to suit your workflow, and dual monitor support makes for a huge improvement in the workflow with the additional space for your image on one display and the various palettes on the other. NX 2 has also improved the integrated Browser to find images as well as apply ratings and labels.

The combination of the Canon EOS 40D and the Hugyfot HFC-40D Housing is an excellent one. The underwater housing fits the camera like a glove and is very compact and waterproof to a depth of 300 feet. Its round curves and matte black colour make this housing look beautiful. Unfortunately it is somewhat difficult to operate the underwater housing for people with small hands. The fisheye port has no obvious distortion and the housing does not suffer from steaming up at all, not even at huge temperature changes. One point of interest is the fact that the camera has to be taken completely out of the underwater housing when its battery needs changing. And the leak detector works too well at times. Live View still needs to be further developed to be of use for underwater photography.


Positives:
++ Very compact size of the underwater housing.
++ The underwater housing is waterproof to a depth of 300 feet.
++ No steam inside the housing at vast temperature change.s


Negatives:
-- The underwater housing is not attuned to small hands.
-- Live View slows down operation.
-- Leak detector is over-sensitive when high humidity rate on land.
-- Changing a battery requires taking the camera completely out of the housing.

Carl Zeiss expands its range of SLR lenses with the addition of the Distagon T* 3.5/18 super wide angle lens. With an impressive field of view of 99°, this new, rectilinear lens provides dramatic perspectives for architectural, landscape and close-range photography for photographers utilizing full-frame DSLRs or film-based cameras. The Distagon T* 3.5/18 is a derivative of the ZEISS designs for the Contax RTS series of cameras, but utilizing all modern materials and eco-friendly glass materials.

The Distagon T* 3.5/18 is designed with a floating lens element in the rear lens assembly, which results in impressive image quality from infinity to the closest focus range. Utilizing the superior ZEISS T* anti-reflective coating and critically designed interior elements, the lens is remarkably free from stray light artifacts and internal reflections. Images are brilliantly rendered, with extremely crisp resolution right to the edges - even at wide-open apertures under the most difficult lighting conditions. Like all Carl Zeiss SLR lenses, the Distagon T* 3.5/18 uses the ZEISS ‘color matching technology', which provides homogeneous color rendition across all focal lengths in the product range. The front filter diameter of 82 mm allows for use of standard screw-in filters when combined with the included lens shade.

In addition to the outstanding optical qualities, the special hallmarks of all ZEISS lenses are designed into the Distagon T* 3.5/18. This includes an all-metal mount for secure mounting to the camera, extreme robustness for professional applications in a wide range of conditions and precision...

The ZD 25mm f/2.8 is a tiny lens. Coupled to an E-4xx series Olympus body, one has a DSLR combination approaching the size of digital compacts. In this comparison, I'll be comparing the bokeh from the ZD lens on an E-420 to that from Canon 50mm f/1.4 lens on a 5D. In other words, I'll be comparing the way the two lenses render out-of-focus, blurry areas when used on their respective camera bodies. This is not a sharpness test, nor is it a test of colors and/or contrast. I used Lightroom for the 5D files and Olympus Master for the E-420 files. The 5D images were downsized to 10MP using Photoshop Bicubic Sharper. Then all files from both cameras were downsized to 25% image size using Bicubic Sharper, and Olympus files were slightly cropped to match the 5D aspect ratio. I used a fixed tripod to match perspective for all comparisons and attempted to match exposure with manual settings.

The SP AF 70-200mm F2.8 Di LD (IF) Macro is Tamron's latest lens, announced at the end of February 2008. A fast telephoto zoom for the more budget-conscious photographer, the design features 19 elements on 16 groups, including three Low Dispersion (LD) glass elements for minimizing chromatic aberration. Tamron say the lens is 'packed with features that allow stress-free photography', and accordingly these are indicated by the plethora of initials packed into that painfully protracted lens name. 'SP' designates this to be a member of Tamron's top-line 'Special Performance' range, 'Di' indicates that it is 'Digitally Integrated' (i.e. optimized for DSLR use, but still covering the full-frame 35mm format), and IF reveals that it incorporates an internal focusing mechanism. Finally the 'Macro' description provides a clue to one of this lens's more interesting characteristics, a minimum focusing distance of 0.95m, which leads to a class-leading reproduction ratio of 0.32x; slightly ahead of the Sigma equivalent's 1m/0.28x, and significantly better than the ~1.5m more typical of this class.

Tamron has something of a history of producing high quality affordable fast zooms, as exemplified by the SP AF 28-75mm F2.8 Di LD Aspherical (IF) Macro, which has become something of a cult classic due to its winning combination of excellent optics, a compact lightweight body and keen pricing (especially in comparison to F2.8 standard zooms from the major camera manufacturers). It's therefore no surprise to see Tamron emphasizing in its publicity material that this product concept has been retained for...
