D300firmware

Nikon has released firmware v.1.02 for its D300 Digital SLR. The update resolves an issue with vertical banding which (very rarely) can appear in images that have been taken at shutter speeds slower than 8 seconds. Click through for the links to the PC and Macintosh downloads.

About this firmware update
The D300 has two different sets of firmware, A and B. This download upgrades the A firmware to version 1.02 only.
This firmware resolves an issue which, in rare cases, causes vertical bands to appear in images captured at shutter speeds slower than 8 seconds.

How to confirm your cameras current firmware version
If the latest firmware versions are already installed on your D300, you need not proceed with download or installation of this Firmware Upgrade. Current firmware versions can be verified from the Firmware version item in the camera's setup menu.

1.Turn the camera on.
2. Press the MENU button and select Firmware version from the setupmenu. The camera's firmware version will be displayed.
3. Turn the camera off.

Quick guide for download and installing this firmware update
Power the camera from AC adapter unit or use a fully charged battery.

1. Download the software from the link below and extract the firmware file "A3000102.bin" .
2. Format an approved memory card in the camera.
3. Connect the camera to the computer (in MSC Mass Storage USB mode) or use a memory card reader.
4. Copy the firmware file "A3000102.bin" to the top level of the memory card.

面额:50比索 国家:墨西哥 制造这种钞票的材料是多层塑料聚合物,在将钞
票倾斜时,塑料聚合物就会改变颜色,使用自制设备仿造这种钞票几乎不可能。而透
明视窗又加了一道安全保险,令其更难伪造。

面额:千元第纳尔 国家:伊拉克 钞票上有凸起的字母符号,令其拥有独特的
质地,上面的油墨只能在紫外光线下才能看得见。

“Di (Digitally-Integrated design)-II” lenses are designed for exclusive use on digital cameras with smaller-size imagers.
This lens is not designed for use with 35mm film cameras and digital SLR cameras with image sensors larger than 24mm x 16mm.

The new SP AF10-24mm F/3.5-4.5 Di II LD Aspherical (IF) is an advanced ultra wide-angle zoom lens that is versatile and offers even higher performance and specifications than the current Tamron SP AF11-18mm F/4.5-5.6 zoom lens.

The lens covers an extended focal length range that is particularly wide for an ultra wide-angle zoom lens, while improving the aperture to F/3.5-4.5 and keeping the filter diameter to 77mm. Its lightweight and compact size makes this new wide-angle zoom very user friendly.

The lens was designed for use with digital SLR cameras and thereby employs special optical glass materials for outstanding optical performance such as large-aperture glass-molded aspherical elements and hybrid aspherical elements.

Main Features

Compact Ultra Wide-angle Zoom Lens Covering a Broad Range from 10mm to 24mm
The new Tamron zoom covers a focal length range equivalent to 16-37mm
* when converted to a 35mm full-size format. Its ultra-wide zoom ratio of more than 2X provides a versatile variety of angles of view, thus improving photographic creativity.
*Tamron’s conversion ratio is 1.5x.

Features an Optical Design Optimized for Digital Camera Characteristics Ensures High Optical Performance

  1. Employment of Special Optical Glass Materials Provides High Performance The new zoom lens uses an HID glass element and a pair of LD glass elements to minimize on-axis and lateral chromatic aberrations that are the greatest hindrance to high optical quality. To further achieve outstanding optical quality, the lens uses a high quality, glass-molded aspherical element and three hybrid aspherical elements to thoroughly compensate for spherical and comatic aberrations and distortion.
    HID – High Index/High Dispersion optical glass
    LD – Low Dispersion optical glass
  2. Optical Design Optimizes the Angles of Incidences of Light Rays Reaching the Imager The ultra wide zoom lens uses a new optical system designed to confine the changing angles of incidences of light rays reaching the imager within a certain scope over the entire image field from the center to the periphery, by considering the effects of variances due to zooming.
  3. Enhanced Peripheral Illumination Peripheral light fall-off is minimized so that images are high quality from the center to the periphery.
  4. Outstanding Resolution As an SP Di II class lens, it provides high optical quality in terms of resolution, contrast and flatness of image field.
  5. Internal Surface Coating Reduces Ghosting and Flare The lens uses a newly developed multiple coating and internal surface coating, (i.e., multiple-layer coatings on cemented surfaces of plural lenses) to reduce the image degradation caused by the reflection of light rays entering from the lens front and affected by the imager.

Ultra Compact and Lightweight Design
The new zoom lens covers a wider focal length range with a greater zoom ratio and offers a faster maximum aperture and enhanced optical quality than the existing SP AF11-18mm zoom lens. Despite higher specifications that are likely to incur a bulky design, the new zoom lens is lightweight and compact. Tamron has successfully realized a versatile ultra wide-angle zoom lens that is lightweight and compact enough in overall length and diameter to accept a 77mm filter, the same as the existing SP AF11-18mm zoom lens.

Minimum Focus Distance of 0.24m throughout the Entire Zoom Range
Considering the importance of “close focusing capability” as an essential condition in wide-angle photography, Tamron has achieved a 0.24m minimum focus distance over the entire zoom range. Getting closer to the subject allows you to easily express a more creative photographic vision.

Flower-shaped Lens Hood
A glare-reducing flower-shaped lens hood is included as a standard accessory. The special hood provides optimum shading of superfluous light rays that enter from the rectangular frame outside the image field.

New External Design Conveying “High Performance, High Precision Image” on the Basis of Tamron’s Conventional Lens Design
The external design is improved to enhance the uniformity and smoothness. The metallic finish of the gold band of Tamron lenses makes it stand out as a Di II lens, while the layout of alphanumerical markings is improved for better visibility. The rubber patterns of the zoom and focus rings have also been improved to compliment today’s digital camera design style and to provide better handling.

Tamron Announces the Launch of SP AF70-200mm F/2.8 Di LD (IF) MACRO

A lightweight, high-performance and fast tele-zoom realizing 0.95m (ft) MFD over the Entire Zoom Range

Mr. Morio Ono, President of Tamron Co., Ltd., has announced the launch of SP AF70-200mm F/2.8 Di LD (IF) MACRO, a lightweight, high-performance and fast tele-zoom lens designed for DSLR cameras with 35mm full-size image sensors.

The new SP AF70-200mm Di LD (IF) MACRO (Model AA001) is an F/2.8 fast tele-zoom designed for DSLRs with 35mm full-size image sensors, inheriting product concept of the existing SP AF28-75mm F/2.8 XR Di (Model A09) that is highly acclaimed as a compact and fast standard zoom lens enabling photographers to enjoy high cost performance characteristics.

While dimensional increases are confined to the absolute minimum, the new SP AF70-200mm F/2.8 Di LD (IF) MACRO zoom lens offers the MFD (minimum focusing distance) of 0.95m over the entire zoom range for the maximum macro magnification ratio of 1:3.1 at f=200mm focal length, for stress-free photography, combined with the advantage of an internal focusing (IF) system.

It enables the user to cover a focal length range of 70mm medium telephoto to 200mm telephoto when mounted on a 35mm full-size DSLR camera and a focal length range from 109mm to 310mm equivalent* ultra telephoto (35mm equivalent, in an angle of view of 7°59’) when mounted on a DSLR camera equipped with an APS-C sized image sensor.

Main features

  1. 0.95m MFD over the Entire Zoom Range for 1:3.1 Maximum Magnification Ratio
    This zoom lens, designed for use with full-size format SLR cameras, boasts a fast maximum aperture of F/2.8, yet it allows close-focusing down to 0.95m over the entire zoom range. The maximum magnification ratio is 1:3.1 at the 200mm tele-end. The filter diameter is confined to φ77mm as a result of the use of an advanced optical design pursuing optimum optical power distribution.
  2. Soft Out-of-Focus Effect and Sharp Depiction
    In order to realize soft out-of-focus effect and sharp depiction performance at the same time, the zoom lens uses three LD (low dispersion) elements. As a result, the optical system effectively compensates for lateral and on-axis chromatic aberrations that are major image-degrading factors in telephoto photography, in order to provide edge-to-edge sharpness and high-contrast image quality with flat-field characteristics over the entire zoom range in various photographic situations.
  3. Lightweight, yet Fast F/2.8 Maximum Aperture
    The lens features a fast maximum aperture of F/2.8, yet it weighs a mere 1,112.6 grams (39.2oz.), since it uses barrel parts made of engineering plastic materials having excellent dimensional stability and sufficient strength for professional use and even industrial applications.
  4. Internal Surface Coatings Minimize Ghosting and Flare
    Through the use of "Internal Surface Coatings (i.e., multiple-layer coatings on cemented surfaces of plural elements) and multiple-layer coatings to prevent reflections from lens surfaces, ghosting and flare due to reflections that occur when light enters through the front element as well as reflections caused by the imager itself in the mirror box are reduced to the absolute minimum.
  5. One-Touch AF/MF Switchover Mechanisms (for Canon and Nikon only)
    The models for Nikon and Canon cameras are equipped with AF/MF switchover mechanisms to allow one-touch switchover from AF mode to MF mode or vice versa electronically and mechanically by simply sliding the button. (Sony and Pentax systems require AF/MF switchover operation on both the camera and lens.)
    Since the lens uses an IF (internal focusing) system, the focusing ring does not rotate during focusing, which ensures good holding balance at all times. In the MF mode, focusing is performed as easily and comfortably as with an MF lens. Since the overall length of the lens does not change due to zooming or focusing, it offers excellent operability and holding balance.
  6. Detachable Tripod Grip Ring
    The lens is supplied with a lightweight and rigid aluminum removable tripod socket.
  7. Flower-shaped Lens Hood
    A flower-shaped lens hood is included as a standard accessory. The special hood provides optimum shading of superfluous light rays that enter from the rectangular frame outside the image field.

Leica to offer M8 shutter upgrade

LEICA M8 – an Investment in the Future
Leica Presents Innovative Concept for Lifelong Value Retention of Digital Cameras

Leica photographers know what they can rely on: superb picture quality, a special handling experience and a camera they can use for years and spans generations. It is the aim of Leica Camera AG to keep on meeting these high expectations in the age of digital technology, and therefore the company is introducing an innovative concept for the lifelong value retention of the digital LEICA M8 at the PMA tradeshow from January 31st to February 2nd 2008 in Las Vegas.

The development of a perpetual upgrade program makes the LEICA M8 a high-quality digital camera in which today’s and tomorrow’s users will always be able to incorporate the latest refinements and developments in handling ease and technology. “While other digital cameras quickly become outdated and are replaced by newer models, our new concept extends the value retention that stands for the Leica brand. Over time, we will gradually offer new product features and developments as upgrade options,“ declares Steven K. Lee, CEO of Leica Camera AG. “Our customers can therefore still invest in the photographic tools they need without worrying that they will miss out on improvements and technological developments along the way. We are confident that this is the right approach for ensuring customer satisfaction and allowing them to continue to sharpen their vision and refine their skills with the new digital LEICA M8. Our efforts will be focused constantly on giving them the best that the world of photography has to offer.“

Over 54 years of research and development have made the Leica M system an almost perfect instrument. With its extensive portfolio of compatible lenses and accessories, it is able to master the most challenging photographic situations. It is the picture quality and the handling experience that make using a Leica M special. Thanks to its durability, it is in many cases an investment for life: it is a photographer’s constant companion and a key to his or her creativity.

Our upgrade concept comprises much more than the usual firmware updates, offering each M8 owner the option of keeping the camera state-of-the-art by integrating new technological developments. The first upgrade package contains the fitting of a scratch-resistant sapphire glass LCD screen cover, as well as, a shutter that is quieter, one that is closer to a well-tuned classic analog Leica M. With the upgrade the customer also gains an all-inclusive worry-free logistic package: Wherever the M8 owner lives in the world, he or she can ask for the M8 to be collected and returned. In addition, all camera functions will be inspected and adjusted by Leica technicians, who will also install the latest firmware. After the upgrade, a LEICA M8 is given a new two-year factory warranty with coverage equivalent to that of a new camera. Further upgrade packages are being planned.

From a technical point of view, all LEICA M8 rangefinder cameras that have ever been built are suitable for the upgrade. The upgrade process is simple: the LEICA M8 user registers for this service on the www.leica-camera.com website. From March 2008, upgrade certificates will be issued for a price of € 1200.- incl. VAT. As the upgrade capacity of Leica Camera AG is limited, the certificates are only available in limited quantities and for a limited period. The camera owner always keeps his or her own M8, the serial no. is not changed.

The benefits of the upgrade in detail:

For this option, scratch-resistant sapphire glass will be used as a cover for the LCD screen. Sapphire glass is the hardest and most scratch-resistant glass there is. This is the reason why it has been used in high-quality watches for many years. Leica is the first camera manufacturer to succeed in using this material for the coverglass of the LCD screen, which is exposed to extreme mechanical wear. Only diamond glass is harder than the sapphire glass used by Leica. Due to its excellent scratch and abrasion resistance, sapphire glass is completely immune to contact with metal, stone or sand. The advantages are obvious: an undisturbed, brilliant view of the display and an LCD screen that looks like new even after years of use.

The new electronically controlled metal-blade slotted shutter offers the benefits of less noise and vibration, allowing the photographer to work even more inconspicuously than before. In spite of the significant noise reduction, it was possible to retain the fastest shutter speed of 1/4000 sec and maximum flash synchronization time of 1/180 sec.
Leica has also managed to reduce vibrations during exposure even further by reducing the kinetic forces. As a result, hand-held exposures with slow shutter speeds are even more sharply defined, enabling the photographer to make even more of the quality of his high-performance Leica lenses.

New firmware version download

In tune with the overall sustainability concept of the rangefinder camera system, Leica Camera AG is now offering all LEICA M8 users an updated version of the camera firmware, which can be downloaded free of charge from the www.leica-camera.com website. Among other things, the new firmware version contains new, substantially improved automatic white balance algorithms for natural color rendering in nearly all light conditions.

The LEICA M8 is the first digital camera in the Leica rangefinder system. It has all the main features of Leica‘s famous analog camera such as the compact design, the remarkable image quality in combination with Leica M lenses and the unique picture composition with the Leica rangefinder. Due to their high performance standards, almost all Leica M lenses produced since 1954 can be used for digital photography. The combination of lens, sensor and powerful image processing produces excellent picture quality with 10.5 million pixel resolution.

FAQ LEICA M8 Upgrade Concept

Status January 31th, 2008

  1. Can all the LEICA M8 cameras in the market now be upgraded, or are there exceptions?
    Any LEICA M8 ever built is suitable for this upgrade.
  2. Are there beside the noise reduction other advantages of the new shutter?
    The reduced kinetic energy also leads to a further reduction of vibrations during the exposure, which in turn results in noticeably sharper pictures in the case of hand-held shots with longer shutter speeds. This allows the extremely high imaging potential of Leica lenses to be exploited even more than before.
  3. Where and when can I have the upgrade performed?
    As an owner of an LEICA M8, you can book and pay the upgrade directly through the Leica Camera homepage. Booking will be possible as of March 2008. You will then receive a certificate with your M8‘s serial number, which you thereupon send us along with your camera. If so desired, we will have your M8 picked up from your home and delivered directly back after the upgrade. The upgrades will probably be possible as of August 2008. You can still acquire a new LEICA M8 at your dealer as before, if you wish, she/he can initiate the upgrade for you.
  4. What advantages does the sapphire glass cover have for the LCD monitor?
    Sapphire glass has a unique scratch-resistance; after all it is the hardest glass of all. It is therefore
    employed for valuable watches and is well-proven in this area. Leica is the first camera manufacturer who has succeeded in using this material for the mechanically very demanding glass
    cover on the LCD monitor. Thanks to its tremendous scratch- and wear-resistance it does not take any damage when coming in contact with metal or stone objects or sand. The advantage is an undisturbed view of the monitor image and a camera whose LCD monitor can look almost new even after years of intensive use.
  5. Which guaranties does Leica offer after an upgrade?
    During the upgrade, Leica will test and adjust your camera in all functions including the download of the newest firmware. After that, Leica will grant a new warranty period of two years which encompasses every service a brand-new camera just leaving the company has.
  6. Does Leica intend to pursue this system in the future?
    The LEICA M8 Upgrade Program is designed to provide our customers with a long-term assurance of their investment, since you can always bring your camera up to date. We are presently investigating the possibility of further upgrade steps including the camera’s complete digital section, even including the sensor itself.
  7. Can I have the upgrades for the shutter and the sapphire glass performed separately?
    This will not be available. Since the camera will have to be nearly totally dismantled, reassembled, and adjusted for each upgrade – a very extensive process, it is more economical to offer both upgrades in one package.
  8. Why should I acquire a certificate for an upgrade now, even though the modifications can only be performed as of August 2008?
    The capacities in the Leica plant in Solms are limited, because the modifications can only be performed by experienced experts. Generally speaking, the upgrades will be done in the order of the incoming certificate acquisitions. Depending on the demand, we are expecting longer waiting
    periods, especially during the beginning of the program. So, it is well worth booking your upgrade as soon as possible.
