Mega-Pixel Vari-Focal Lenses
|
|
Tamron makes a series of mega-pixel compatible vari-focal lenses that derive the maximum performance from mega-pixel high-resolution cameras.
Tamron's mega-pixel compatible Vari-Focal lenses incorporating advanced optical systems ensure high resolution and high contrast performance over the entire image field, from the center to the periphery.
Also, these lenses are the most suitable for the image cut-out function of IP cameras.

Flat-Field Mega-Pixel Lens
Delivering Uniformly High Resolution Image from Corner to Corner
The Tamron Flat-Field Mega-Pixel Lens Series delivers Mega-pixel image quality not only in the center but also in the corners of the image eld,
providing the mega-pixel resolution quality needed for image cropping and enlarging of image,
irrespective of the location of the subject on the screen. This ensures that subject faces and other relevant information can be clearly identi ed and distinguished,
making the Tamron Flat-Field Mega-Pixel Lens an ideal solution for high resolution network surveillance applications.
In fact all lenses of the Tamron Mega-Pixel Lens Series lineup deliver Flat-Field Mega-Pixel resolution.

Key Mega-Pixel Technologies
Key Technologies Supporting with Mega-Pixel Compatibility
Each lens in Tamron,s Mega-Pixel Vari-Focal Lens Series uses Aspherical elements to minimize optical aberrations and
ensure high optical quality while maintaining a compact form.
Employing innovative optical technologies, these lenses deliver high resolution and high contrast images that are sharp from the center to corner of the image eld,
and represent the ideal solution for application that use high quality mega-pixel cameras.

F/1.0 lens has two times light gathering power compared to F/1.4 making a 1 lux camera sensitivity into a 0.5 lux sensitivity.
|
Wide Dynamic Range
The fast aperture of F/1.0 makes it possible to obtain vivid color images even in dim lighting conditions such as dark rooms and corridors,
or in the early morning or evening hours when the ambient light would ordinarily be insuf cient to capture high-quality images. A fast lens is able to gather a large amount of light,
thereby enhancing the sensitivity of the camera.

|
|
Multiple-Layer Coating
Multi-coating is applied to internal and external lens surfaces to minimize ghosting and ˆare in backlit situations.
The result is consistently sharp contrast and excellent image quality even under unfavorable lighting conditions.
|
|
|
Slip-Mount Mechanism
Each lens is equipped with a slip-mount mechanism that allows rotational adjustment of the lens after it is mounted on a camera.
This allows optimal positioning of the auto-iris actuator and cable during installation.
|
|
Supporting up to 1/2.7″ Sensors
The large image circle makes it possible to match with 1/2.7�h, as well as 1/2.8″ and 1/3″ sensor sizes.
Due to variance in such sensor sizes,
it was essential to incorporate such design.

|
Locking Mechanism for each Control Ring
Each control ring for zoom, focus,
and iris size* can be independently locked to prevents setting displacement after installation.
(*:Manual iris only)
|
|
P-Iris
By using a stepper motor to control the iris, this lens is capable of adjusting the aperture at a position that does not cause diffraction,
enabling an appropriate level of exposure by utilizing the camera shutter speed.*1 The result is that high quality,
high contrast images can be recorded, even in bright outdoor areas.
This ne tuning control will allow the user to acquire the best image quality delivering good depth of eld at most installations.
*1:Connecting the lens to a camera that does not support the P-Iris technology may cause malfunction.
The lens cannot be connected to cameras that use DC auto iris or video auto iris lenses

|
Large Focus Rotation Angle
The rotation angle of the focus ring has been increased to achieve easier and more precise focus adjustment for Mega-Pixel camers.
|
|
|
Compact Design
Mega-pixel resolution is achieved while maintaining the compactness of conventional lenses.
|
|
Precision Manufacturing
Each component in our Flat-Field Mega-Pixel Lenses is produced and assembled using the most advanced precision manufacturing techniques to prevent image degradation due to local blur and focus shift.
