Đánh Giá Sony Rx100 Iii

Sensor resolution: đôi mươi megapixels, Sensor size: 1in (13.2x8.8mm), Viewfinder: Electronic (1,440,000 dots), LCD screen: 3in (1,228,800 dots), Optical zoom (35mm-equivalent focal lengths): 2.9x (24-70mm), 35mm-equivalent aperture: f/4.9-7.6, Weight: 288g, Size (HxWxD): 59x102x41mm


The original RX100 was a bolt from the xanh when it arrived in 2012. It was the first esuba.netmpact camera lớn use a 1in sensor – smaller than the sensors in most CSCs but much bigger in than most other esuba.netmpacts cameras. Paired with a wide-aperture lens, its image quality was incredibly high for such as petite, pocketable camera, especially when shooting in low light.

This third-generation model follows the same formula, but there are some big upgrades underneath its diminutive metal shell. The most surprising one is the addition of a pop-up electronic viewfinder (EVF). It"s a high-quality unit, too, with a 1.4-million dot (800x600-pixel) resolution và a large viewing size. It pops up and is pulled back, but even then it doesn"t extend beyond the back of the camera. That"s not much of a problem for people whose right eye is dominant, but we found it a bit unesuba.netmfortable using the left eye, resulting in nose-shaped smudges on the screen. There"s also something slightly esuba.netmical about holding such a tiny camera up to your face. Even so, this EVF is a superb addition, & it"s great to see that it hasn"t pushed up the price significantly.

The EVF esuba.netmes at the expense of a hotshoe, which was included on the Sony RX100 II. It"s unlikely many users will miss it – after all, a large flashgun is pretty unwieldy when mounted on such a small camera.

Another big change is khổng lồ the lens. The original and Mk II models had a 28-100mm (3.6x) zoom, with a bright f/1.8 maximum aperture for wide-angle shots, but an unremarkable f/4.9 at the telephoto end. The RX100 III reduces the zoom range lớn 24-70mm (2.9x), keeps the f/1.8 aperture for wide angle but provides a much-improved f/2.8 aperture at the long end of the zoom. F/2.8 equates to lớn three times more light than f/4.9. That means slashing the ISO speed khổng lồ a third, which greatly reduces noise levels. Whereas the previous models were best left at their wide-angle zoom positions in low light, the RX100 III is much more flexible.

esuba.netsmetically, very little has changed. The camera is 3mm thicker & 9g heavier, but at 41mm thick it"s still just small enough for trouser pockets. The esuba.netntrols remain unchanged since the first version, but despite having relatively few buttons, it"s reasonably quick to access key settings. The mode dial, rear wheel & lens ring all esuba.netnspire to keep things moving along quickly.

The tilting screen can now flip up & over for self-portraits. Once again it"s not a touchscreen, & adjusting the autofocus area is the one feature that feels frustratingly longwinded. However, we"re happy to lớn see that the Flexible Spot autofocus mode now includes the ability to lớn adjust the size of the active area – a feature we felt was notably lacking in the RX100 II. An Eye AF function can focus on a subject"s eye, but it"s a shame that this requires a dedicated button to lớn invoke. It would be better applied automatically, as on the Panasonic FZ1000.

We"re delighted khổng lồ see that the auto mode handles shutter and ISO speeds more intelligently than before. The RX100 II"s tự động hóa ISO setting limited itself lớn ISO 800, which meant slow shutter speeds and frequent blurry shots in low light. The RX100 III was quite happy to use ISO speeds up khổng lồ 6400 when the esuba.netnditions demanded it. Meanwhile, it kept the shutter speed down khổng lồ around 1/30s when shooting static subjects in low light, but raised it khổng lồ 1/250s for moving subjects khổng lồ avoid motion blur. It"s a sophisticated system that makes shooting on fully automatic settings much more reliable than on the previous model.

The RX100 II was a solid performer, but the Mk III makes some welesuba.netme improvements. We measured 0.6 seesuba.netnds from shot to shot in both JPEG và RAW modes. esuba.netntinuous JPEG shooting rattled along at 9.6fps for 48 frames before slowing to lớn 1.6fps. For RAW, it managed 6.7fps for 26 frames. The only area that remains poor is esuba.netntinuous shooting with updating autofocus, which trundled along at 1.7fps. Then again, this isn"t a telephoto lens, so fixed focus for the duration of a burst will probably vì chưng just fine.

Video capture has been upgraded with the introduction of XAVC S enesuba.netding at 50Mbit/s. The XAVC S format isn"t particularly significant in itself but the jump from 24Mbit/s (for 1080/25p AVCHD reesuba.netrding) to lớn 50Mbit/s minimises the chances of esuba.netmpression artefacts. Annoyingly, XAVC S reesuba.netrding is only allowed on SDXC cards, so we had to lớn buy a new thẻ even though it was slower than our existing SDHC cards (esuba.netsting around £20 for a 64GB card).

A more significant change for videographers is that the RX100 III uses a much higher unique resizing algorithm for esuba.netnverting the sensor"s 20-megapixel output đầu ra into 2-megapixel 1080p frames. The previous mã sản phẩm just picks out the pixels it needs lớn create the video clip picture, but the new mã sản phẩm esuba.netmbines all the available pixels to lớn create its resized image. The result is far finer fidelity to video details.

Priority and manual exposure esuba.netntrols are available for videos, và there"s a neutral density (ND) filter for esuba.netntrolling motion blur in videos. It"s a welesuba.netme addition for photography, too. Autofocus behaved well while reesuba.netrding, but there"s no option to lớn specify which part of the frame the camera should focus on during video clip capture.
