Canon Powershot SX170 IS is the latest release in autumn 2013 launch of a compact digital camera, and is an upgraded version of the Canon SX160 IS routine of. Canon Powershot SX170 IS uses a 1/2.3 inch, 16.1 million effective pixel CCD image sensor, consistent with its predecessor, in addition to Canon Powershot SX170 IS is also equipped with a 16x optical zoom lens 一枚 function, focal length of 28 – 448mm, the digital zoom can be achieved with nearly 1000mm telephoto capability, performance tough enough on SX160 IS 720P HD video capture has also been inherited.
A Canon Powershot SX170 IS first post-test
For slightly touched photography friends will know, camera card has been somewhat lacking in maneuverability, but many products under the Canon stratification can find a suitable machine. Wherein the portable digital camera category where there are individual representative SX series, where users can find products corresponding to different user needs, there are a number of high-end machines (like a long time does not appear flagship product), as well as double-digit three-digit product, which is a three-digit machine although at a lower entry-level, however, the G series camera card aside from the sensor to the lens SX series camera hardware is closer to the top of the card.
SX Series essence in the minds of users have left a high-profile, large telephoto, synonymous with a low price. Although the G Series champion in camera card, but the entry-level SX series are still occupy most of the market share, Canon will not easily give up, but can not just give up.
With increasingly powerful mobile phone photography, portable camera card in front of the plight becomes more and more severe. If you want to catch the consumer’s appetite, then you must want SLR cameras, single-camera or even a cell phone does not have the features to start, before losing the ability to protect the site. In recent years, the demand for more and more cameras, especially in the camera card ranks, the more prominent if the product is not selling, it is difficult to get consumers. In recent years, in addition to SLR cameras, single-camera, is another very popular with consumers camera telephoto machine types.
Telephoto machine name suggests is to have a relatively high multiple optical zoom capability, consumers do not need to change their stations to shoot near or distant objects. Canon in recent years introduced many popular telephoto camera products, the latest generation of its Hirohide series products Canon Powershot SX170 IS also came to our side.
Second, the overall appearance of the Canon Powershot SX170 IS Review
Canon Powershot SX170 IS and SX160 HS in appearance more similar, the continuation of the SX series of classic design, the front there is still designed to be very simple, positive elements to be only a handful of huge 16x optical zoom lens occupies nearly half of the area, and the coating around the lens with red primary color contrasts. Compared SX160 IS sleek design, the Canon Powershot SX170 IS is positive people feel more Founder, particularly marginal position is not a sleek sides, replaced by a water chestnut design. The same metallic body with black, silver, red 3 colors optional, the songce version is red.
The back is a 3-inch 230,000 pixel display pixel LCD display and a number of function keys. Compared to some of the terms of a compact camera cards, physical keys Canon Powershot SX170 IS area ready for users is still relatively large, only a proportion of the back button has accounted for nearly one-third, which can make every Canon Powershot SX170 IS The relatively large keys done to prevent inadvertently. Similarly, the key process is also designed to cater to the frequent use of touch-screen users. Notably, Canon specifically for the user to keep the top of the screen a small space, the user can prevent the case mistakenly struck by the rapid shooting mode dial, the design is very intimate.
Given the decision to locate the SX series models are not thin line through points. Canon Powershot SX170 IS’s body volume of 108 × 71 × 43.9mm (excluding protrusions), compared to the SX160 IS is 111.0 × 72.5 × 44.1 毫米 more then a small number; addition weighs 251g (including battery and memory card) compared with 243 grams of weight has increased, but the actual operation is not too obvious feeling. But even so the Canon Powershot SX170 IS is relatively small in the SX series models the (comparative sense though with the card machine body is really not). Top is the mode dial, power switch keyboard and function lever.
Also included at the bottom exterior of the fuselage are designed with a matte texture, highlighting the atmospheric minimalist style. Overall compared to the previous generation of products and changes in the appearance of the part is not especially prominent, the general design style and layout are basically the same, in fact, in the SX series of such hardware layout has become a certain routine, so even if there is overlap Department is not surprising. But such distortion, the overall feel is always good.
Third, the Canon Powershot SX170 IS introduce local appearance
Previous article talked about the problem of the lens, the Canon Powershot SX170 IS as an upgrade though but not much on the lens configuration changes, perhaps because of cost considerations, SX160 IS is an upgraded version of the Canon Powershot SX170 IS is equipped with 一枚16 optical zoom lens, the focal length of 5.0-80mm (35mm equivalent focal length of approximately 28-448mm), aperture of F3.5-5.9, this lens appears on the predecessor indeed a very cost-effective, mid-range lenses are law-abiding, But to the upgraded version also uses the same lens, the level of contrast becomes behind, even though we will be seen as the Canon Powershot SX170 IS predecessor patched version. In actual use, in addition to the zoom magnification and intelligent IS and not too bright spot outside, just from the parameters concerned is a very practical focus lens.
The same button on the top of the fuselage also be arranged in a similar layout, the difference is only in the upper right side of the SX160 IS a towering black shell was replaced in line with the fuselage red (in fact, Xiao Bian also in the evaluation SX160 IS reason to think this piece of black design). Mode dial gear designed to keep the same strain with the SX series, the operation buttons on the right side top of the camera, and users can easily be carried with one hand and the shutter mode and switch operation.
I believe the evaluation was seen SX160 IS friends will feel its use AA batteries very surprised, although retro feeling full, but as a practical camera cards, so bring an additional burden on the user and endurance power enough to force (ie uses rechargeable AA batteries) the performance advantage is not to be covered by the rest. Canon Powershot SX170 IS supports the model NB-6LH, 1060 mA lithium battery capacity when, with lithium battery technology continues to mature, in fact, the advantages of AA batteries do not seem very obvious, will be replaced by a rechargeable battery type of lithium battery design, so both light and can guarantee a better life, more than just the user will be able to dispense with a backup power life worries.
In flash, the Canon SX160 IS dedicated to providing a manually open flash button (in the fuselage behind the top of the screen), but to the Canon Powershot SX170 IS has found the button disappears, the upgrade for the original Canon fuselage This optional buttons removed, because even without this button can still open (but not recommended), is replaced by the user directly mention the flash. Configuration, the official website of the flash configuration did not elaborate, small flash index is probably around GN7, as an emergency is good. In addition, when power is not sufficient to use fast charging (the lamp itself may also be hardware limitations), so after using the flash when shooting or wait a few seconds to charge.
Fourth, the Canon Powershot SX170 IS features and upgrades points
1, the battery replacement program – the root cause of high-endurance
Since lithium battery technology develops to a certain level to gradually fade rechargeable batteries nickel-chromium-field image of the product life solutions, power configuration scheme of digital imaging products has always been a designer needs to overcome the problem. Since SX160 IS costs and design needs, using AA batteries as a power scheme is really small series was a bit surprised, though aspects of sophisticated electronic products but either AA batteries power capacity or conversion rates are slightly inferior to lithium battery.
Most importantly, the power of two AA batteries so that the composition of the body volume instantly become very “card”, let alone a spare battery in the weight burden on the user. So redesigned power scheme became Canon Powershot SX170 IS major hardware upgrade points, using lithium AA batteries to replace the preferred body weight can make a big down, naked body weight difference of only 20 g , complete with battery storage card but the gap reached 40 g (SX160 is about 290 grams, Canon Powershot SX170 IS compared to 250 g), which for a 300 g body can not be ignored in terms of proportion.
Even the weight drop down, but still feel good. Xiao Bian when carried on the Canon Powershot SX170 IS handheld shooting grip and not because of the weight of the decline worse. It is worth noting that all the corresponding reduction in the Canon Powershot SX170 IS handles the site area and thickness (contrast seen in three dimensions), but the practical operation of the button box Washing have no significant impact.
2,16 x optical zoom – zoom and focus speed has a slight improvement
In the previous article we mentioned the Canon Powershot SX170 IS lens did not make the upgrade, in fact, such a statement is not objective. Due to changes in power supply design led to work with the machine need to re-adjust the amount of adaptation, the most important is the Canon Powershot SX170 IS lens motor on debugging made a little fine-tuning, this from the appearance simply do not see, even is part of the structure of the lens drive will not be a very significant difference. Canon Powershot SX170 IS is an entry-level machine SX series rare, but it is still the biggest highlight of the zoom lens at high magnification. 35 mm equivalent focal length of 28-448 mm lens in the market although not the biggest zoom digital camera, but cost control, care to make a better balance between practicality.
Due to the structure of the lens does not make a change, so imaging can be said to be maintained at a relatively formal level. Of course, the quality in the use of digital zoom (64 times) is much less after using only the optical zoom, but occasionally use a small picture size digital zoom, or can, I believe this definition is adequate for home users.
After all, look back at the positioning of this machine can achieve more than 1000 mm super-telephoto shooting capability far beyond the capabilities of this camera, and at the same time in the development of environmental sustainability telephoto lens performance machines, Canon Powershot SX170 IS added digital zoom function more out of practice and consideration. I believe the future will have more than 1000 mm optical zoom entry-level telephoto appear.
