Broj megapiksela vise ne raste. Ono sto je posebno za pohvalu - svi se drze senzora vecih dimenzija, a uvode se i neki AF noviteti.

Fujifilm unveils F300EXR compact superzoom with Hybrid autofocus system

"Second generation EXR Sensor technology NEW! Hybrid Auto Focus System NEW!
One of the disadvantages of longer zoom compacts is relatively slow auto focusing. Typical compacts rely on Contrast Detection, which works by fixing the focus by searching for contrast differentials. Some expensive cameras, including many DSLRs, use two focusing systems in tandem to improve the time taken to auto focus. Phase Detection AF works by dividing the incoming light into pairs of images and calculating the phase difference to find if the object is in front focus or back focus position. Contrast AF is generally better in low-lit scenes, while Phase Detection AF is extremely responsive in good light. Having both systems on one camera is perfect. The FinePix F300EXR uses both Contrast AF and Phase Detection AF to offer auto focus speeds as good as, or sometimes better than expensive DSLRs. To achieve the incredible AF speed of 0.158*1 seconds, Fujifilm engineers placed pairs of phase detection sensors on the EXR sensor, which work exactly like external sensors on DSLRs. The FinePix F300EXR automatically selects the optimum focus system, by measuring the amount of light or contrast in the scene. The benefit for the photographer is immediate and obvious: an almost instantaneous capture of the subject in the viewfinder, with no missed shots or subjects half out-of-frame."

Jedino me brine objektiv, pocetna blenda je f 3.3


Ovaj mi se takodze svidza, jure oni napred samo tako!

Panasonic officially announces DMC-LX5 premium compact
Panasonic has officially unveiled the DMC-LX5, successor to the popular LX3. The latest model features a revised sensor, longer zoom range and improved control layout without fundamentally changing the existing model's formula. It offers a more flexible 24-90mm equivalent lens with a bright F2.0-3.3 maximum aperture range and a comparatively large 10MP sensor in a small body. The body itself is barely changed compared to the LX3 - gaining an improved hand grip, clickable control dial, direct movie record button and a 1:1 position on the aspect ratio slider. Most significantly it gains a connector to add the DMW-VF1 electronic viewfinder originally launched with the GF1. Other than this, the LX5 gains the AVCHD Lite format for its 720p video, and its image stabilization is branded with the company's latest 'Power O.I.S' designation. We've had a chance to use an LX5 for a bit, so have prepared some notes on our first impressions.

Compared to the LX3:

The 1/1.63" (~0.45cm²) sensor itself has been redesigned and an additional layer of condensing microlenses added to offer increased sensitivity and saturation figures, resulting in an improvement in dynamic range. The user interface has also been revised, with a GF1-style clickable control wheel replacing the LX3's joystick, making it easier to change settings. Most significantly the lens range has been extended to offer a more flexible 24-90mm equivalent range while retaining a bright F2.0-3.3 maximum aperture range (it also matches the LX3's lens brightness over the shared focal length range).

Ovo ce da zakopa S90. Osim mozda po gabaritima.

Nikon, Canon... what the hell you are waiting for?

i ona galerija sa primjerima sa panasonica izgleda jako pristojno, a raspon objektiva je po meni odlican, panasonic je kompanija koja je vjerovatno najvise napredovala u zadnjih nekoliko godina na polju digitalaca, jedan mocni sony treba da se stidi kad pogleda sta je panasonic napravio.

^^ Jedna od najznačajnijih inovacija iz oblasti fototehnike u zadnjih par godina!!!

Kad' tad', ovakvi AF senzori će se naći u svim aparatima i kamerama, bilo deseler (k'o dopuna standardnom AF sistemu a pogotovo live wiev-u), bilo kompakt škljocarama, bilo mirror less velikosenzorskim aparatime, bilo videokamerama...

Živeo Fuji!
