Panasonic PMA new machine decomposition

Panasonic announced a new product in the spring of 2006 LUMIX series digital cameras in the PMA show, there are DMC-FX01, TZ1, FZ7 and LZ5, in Panasonic's booth also showed TZ1, FZ7 and FX01 decomposition model.
Panasonic TZ series digital camera positioning in the "travel type telephoto camera". Compared with general telephoto camera, TZ1 to do the minimization of volume, but also provides the optical zoom up to 10 times.
Panasonic TZ1 uses 3 times optical refractive optical zoom Leica lens design of the front lens group, because of greater than general card level camera, so this machine in still provides F2.8 large aperture. TZ1 also provides optical anti-shake mechanism, can avoid the jitter effects on the camera image quality in a certain range. TZ1 used a 4:3 scale 6370000 pixel CCD, but can only use 5000000 pixel regions, TZ1 supports the shooting mode 16:9. Also worth mentioning is, this machine can capture video in 16:9 mode, and in the 848 * 480 resolution still provides 30fps high-definition video shooting.
Panasonic FZ7 decomposition model, 12 times optical zoom lens has the most volume
Panasonic in 2006 of the first telephoto digital camera DMC-FZ7 released last year FZ5 upgrade products. With the same 12 optical zoom lens and MEGA O.I.S. anti-shake system, and increase the high sensitivity luminosity function.
Panasonic FX01 decomposition model, its body than the general card machine thick some, but powerful lot
Panasonic FX01 characteristics is the biggest 28mm wide-angle lens increased in the narrow fuselage volume at the same time, wherein the lens with a known as new aspheric lens EA lens, this is a super high refractive index aspherical glass polishing lens, the refractive rate of more than 2 of the high refractive glass (K-PSFn2) manufacturing. Where EA is the Extra High Refractive Index Aspherical abbreviation. Plus 3 other aspheric lens, so as to realize the ultra small volume only 6 groups of 7 lenses will achieve the equivalent 35mm camera 28mm ~ 102mm wide-angle zoom lens.
Panasonic FX01 is a near perfect digital camera, its ISO value is 1600 and has a O.I.S optical Panasonic digital camera has been equipped with anti-shake system, coupled with the wide end of the Leica lens and Venus image correction engine, the Panasonic FX01 into a powerful digital camera configuration.
In a slimmer fuselage and large screen LCD has become the mainstream now, the development direction of consumer digital camera gradually to optical anti-shake, high sensitivity and the wide-angle lens. Panasonic digital camera optics as forerunner, always have a strong position in this field, and the spring of 2006 LUMIX series digital camera marks the Panasonic digital cameras and also to the small big zoom lens, high sensitivity, wide angle lens development.

Pocket DV fashion Panasonic 3CCD

I heard a Panasonic Corp under a new model for the S100GK pocket 3CCD digital video camera.
As a leading revolutionary DV attention, S100GK is not only that a selling point, based on imaging system using 3CCD, also introduces a high capacity SD card as storage medium. And because of this, therefore, its size (width * Height x thickness) of just 49.9 x 96.7 x 80.4 mm, can be inside his coat pocket to relax, greatly improves the portability. With battery and SD card after the weight is only 243g, only half the weight of the Mini tape type digital camera, can be said to be worthy of the name of the mini 3CCD digital cameras.
Performance of SDR-S100, the Leica lenses composed of 8 groups of 12 pieces (3 pieces of aspheric optical lens), the focal length of the lens is f = 3mm~30mm (equivalent to 35mm camera: shooting video, f=46.1mm~461mm (4:3), 47.1mm~471mm (16:9); static pictures taken, f=43.4mm~434mm (4:3), 47mm~470mm (16:9)), aperture is F1.8/2.8, and has a 10 optical zoom, 25 times /700 times digital zoom function.
The left side of the SDR-S100 occupied by the liquid crystal display screen. The liquid crystal display using the 16:9 wide screen mode, a resolution of about 210000 pixels, the size of 2.8 inches, may say that is more suitable for more and more wide screen TV needs. In SDR-S100, the electronic viewfinder common is not set, this is perhaps the need to reduce product volume.
Input, output interface of SDR-S100 is also located in the rear fuselage, mainly by the USB2.0 interface, MULTI interface and power interface of multimedia. With a model for the CGA-S303 rechargeable lithium ion battery, the capacity is 760mAh, nominal continuous shooting time is about 80 minutes, intermittent time about 45 minutes.

Nikon Coolpix A sensor test results came out

In the recently released DxOMark laboratory nikon DX format portable digital camera Coolpix sensor test results, A comprehensive score 80 points, and the nikon D7000 flat.

Coolpix carrying A and D5100, the D7000 specifications the same 16.2 million pixels APS - C sensors, including 23.4 bit color depth 13.8 EVs, weak sensitivity, dynamic range, ISO 1164, evident from these results, the three actual gap is very small, but the result has been more than the vast majority of portable digital camera, even without the camera.

DxOMark also notes that while ahead of Coopix A nikon D5200, D7100 and pentax K - 5 series, but as A portable digital camera, Coolpix A photo quality is close to or beyond the introductory many DSLR, in the end, it also makes it to the top ten places in APC - C.

It is also a minimum APS - C in the history of the camera. If we use one sentence to summarize the nikon COOLPIX A (hereinafter referred to as the nikon small A) what are some of the characteristics, that is the smallest APS - C in the history of the camera, of course you want to do this is not too easy, quite apart from what other design, APS - C sensor itself has very big size, so the sensor flange distance can not be too small (at least 2-3 mm), so big of the sensor can directly lead to the lens volume increased, so the APS - C camera I want to be thin, really difficult.

To control volume, nikon had A lot of kung fu is not only in terms of the overall circuit, the lens is also specially designed, nikon small A 18.5 mm f / 2.8 lens specifications, 7 pieces of 5 groups took seemingly very simple design, although in theory exceed short flange lens is better to do it, but digital sensors for the vertical incident light, and the vertical incident will greatly increase the lens size, it will give this camera increased A lot of problems.

APS - C 16.08 million pixels CMOS sensor (actual output size 4928 x 3264); No optical low pass filter
ISO ISO range of 100-6400 (expandable to 25600)
EXPEED 2 image processor specific models for EI - 154

1080/30 1080/30 p p video shooting
Built-in double track the microphone
Shutter speed of 1/2000 s highest life 150000 times
SDXC card slot support UHS - 1 standard
Through the wireless network adapter can be connected to the intelligent device (Android and iOS); Support for wireless remote control

Tascam new DR - 60 d SLR cameras, audio accessories to break an unprecedented audio recording function

Tascam, the end of March 2013, has announced its specially designed for digital SLR camera (DSLR) user's new audio accessories, photographer and filmmaker can better use it to record video, without back more recording equipment. DR - 60 d is a use 4 AA batteries of the type of equipment, support for SD and SDHC memory card, can provide 96 KHZ / 24 - bit audio recording, and computer transfer files via the USB port. Audio can be recorded into the BWF WAV format. The support Auto Rec and Dual Rec mode.

DR - 60 d design to match the SLR camera to use, but also can be deployed to a recording equipment (recording rig).

DR - 60 d has two 1/4 "XLR Locking Combo mic/line input interface (+ 48 v Phantom Power), a standard 3.5 mm stereo microphone input ports, camera input/output, as well as the headphone output interface.

Its also has a timer (self - timer), file segmentation (file divide), up to CH3-4 monitor selector (monitor the selector), + 24 is a type, low cut filter (low cut filter), peak limiter (peak limiter), input lag (the input delay) and MS decoding, and other functions. For amateurs and professionals, it is a good choice.

Manual control, the fuselage design to avoid introducing don't need to control the noise; This includes the soft buttons and dials. Tascam created its user interface for the system to be very easy to use, intuitive and manipulation has multiple recording mode; This includes an automatic mode, and its popular Safety Track mode.
