Nikon has launched the D5200 and D7100 digital SLRs in quick succession.
Both have 24-megapixel sensors, both use Nikon DX format lenses, and both are designed for photo
enthusiasts. So how do you choose between them?
Nikon最近短時間內接連發表了D5200和D7100，
他們都有2400萬畫素的感光元件，都是DX格式，也都是為業餘玩家所設計。
那麼，你該選哪一台呢?

Our detailed Nikon D7100 vs D5200 breakdown shows the key differences between these two cameras –
and don’t just assume the more expensive camera is the best because there are pros and cons to each, as we reveal…
我們詳盡的D7100 vs D5200分析將指出這兩台相機的關鍵不同處
-別以為比較貴的相機就是比較好，他們都各有優缺點，請見以下分析…

Nikon D7100 vs D5200:

1.感光元件:低通濾鏡的有無
1. Sensor: Aliasing vs non-aliased
Both cameras have a 24-megapixel APS-C sensor measuring 23.5 x 15.6mm. Nikon claims that the sensor in the D7100 is a brand new design, but the key point for most users will be the fact that Nikon’s left out the
OLPF (Optical Low Pass Filter), also known as the anti-aliasing filter, in front of the sensor. These are used to prevent moiré (interference effects) with fine patterns and textures, but at the cost of slightly blurring the fine
detail. Nikon’s decided that the size and resolution of this sensor makes moiré unlikely and that the gain in sharpness from removing the filter is a bigger benefit. As a result, although the D7100 and D5200 have the
same resolution, you can expect the fine detail from the D7100 to be slightly sharper.
兩台相機都是尺寸為23.5 x 15.6mm、2400萬畫素的APS-C感光元件。
Nikon說D7100的感光元件是全新設計，但對多數用戶而言，
關鍵的是它在感光元件前少了光學低通濾鏡 -也稱為反失真濾波器。
那是在拍攝細微圖案或質地時，用來避免產生摩爾紋(干涉效應)，但使用低通濾鏡會使畫面稍微模糊掉一些細節。
但Nikon認為這個感光元件的大小和畫素不太會產生摩爾紋，但移去低通濾鏡的一大好處便是換來更佳的銳利度。
結論就是，雖然D7100和D5200都是2400萬畫素的感光元件，不過可以期待D7100對細節的呈現會稍加銳利。

2.對焦點數目:39點vs51點
2. Autofocus: 39 points vs 51

The D7100 uses the sophisticated 51-point autofocus system used by Nikon’s professional digital SLRs,
whereas the D5200 uses a slightly less advanced 39-point ‘amateur’ version. Both are fast and powerful by any standards, but you can expect the D7100 to have a slight edge. It has 15 more sensitive ‘cross-type’
sensors compared to 9 cross-type sensors in the D5200. The D7100’s autofocus can also be used with
lenses that have an effective maximum aperture of f/8, which is important if you’re going to use telephoto
lenses and teleconverters.
D7100使用了專業級相機所採用的51點自動對焦系統，而D5200則使用了比較沒那麼進階的39點"業餘"版本。
兩者都很快速及強大。但可以想見D7100還是比較佔優勢，他有15個十字對焦點，而D5200則是9個十字對焦點。
D7100的自動對焦也可用於等效最大光圈為f/8的鏡頭上，如果你想用望遠鏡頭或增距鏡時，這點很重要。

3.機身馬達的有無:
3. Autofocus: AF vs AF-S

The D5200’s smaller body does not contain an autofocus motor. That’s fine if you intend using Nikon’s
later AF-S lenses, which have their own autofocus motors, but not if you have older AF lenses, where the focus mechanism is driven by the camera body. The D7100 has an autofocus motor built into the body – you can
see the tiny drive shaft in the lower left corner of the lens mount flange here – so the autofocus will work fine with these older lenses. (Note that some older independent lenses don’t have autofocus motors built in either.) The D7100 has the advantage if you have older lenses in your collection or you’re planning to get some.
D5200嬌小的機身並不包含自動對焦馬達。如果你只用Nikon比較新的AF-S鏡頭的話就沒差。
因為他們鏡身內都有自己的自動對焦馬達，
但如果你要用比較舊的AF鏡頭時，他的對焦機制必須由機身來驅動。
D7100有內建機身馬達，所以可以搭配比較老的鏡頭來使用。(更老的手動鏡例外)
所以如果你已經有一些老鏡或準備要買的話，D7100比較適合。

4.記憶卡槽:1槽vs2槽
4. Memory: 1 card slot vs 2

The D5200 has a single SD/SDHC/SDXC memory card slot, but the D7100 has two. This isn’t simply to
provide extra storage capacity – the real benefit is that you can use the second card to split JPEG and RAW
files, for example, or you can use one card for stills and the other for movies, or you can use the second card to keep a running backup of your images as you shoot. It’s not a major advantage for amateurs, but it could
be a useful feature for experts or pros.
D5200有單一的SD/SDHC/SDXC 記憶卡槽，但D7100有兩個。這不是單純提供而外儲存空間而已，
真正的好處是你可以分開存JPG和RAW，或者一張卡存照片一張卡存影片。
也可以把第二張卡作為拍攝時的備份卡。
也許對於業餘玩家用不太到，但這對進階或專業使用者來說是很有用的。

5.觀景窗:五面鏡 vs 五稜鏡
5. Viewfinder: Pentamirror vs pentaprism

The D5200 uses a cheaper ‘pentamirror’ design which covers 95% of the image area the sensor will
capture, but the D7100 has a more expensive and traditional ‘pentaprism’ design which provides a better
image and covers a full 100% of the image area. You may not notice the difference if you use either camera individually, but you will if you put them side by side.
D5200用的是比較廉價的"五面鏡"設計，他只有95%的影像覆蓋率。
但D7100用的是比較昂貴的傳統五稜鏡，提供較明亮的視野和100%影像覆蓋率。
如果你一次只用一台相機的話可能感覺不出差別，但兩台同時比較時就有差別了。

6.快門速度範圍
6. Shutter speed range

The D5200 has a shutter speed range of 1/4000 sec to 30 sec, while the D7100 goes from 1/8000 sec to 30 sec. It has a small advantage, then, but the situations where you’ll actually need or want to shoot at 1/8000
sec will be pretty rare. More usefully, the D7100 has a flash sync speed of 1/250 sec, whereas on the D5200
it’s 1/200 sec. This gives the D7100 a slight advantage for fill-flash photography in bright daylight.
D5200的快門速度範圍是1/4000 秒~ 30 秒，D7100則是1/8000 秒 to 30 秒，D7100小幅領先。
但其實會使用1/8000 秒拍攝的場合很少。比較有用的是，D7100的閃燈同步速度是1/250 秒，
D5200則是1/200 秒，這使得D7100在白天的強制閃光攝影比較有優勢。

7.連拍速度:5fps vs 6/7fps
7. Continuous shooting: 5fps vs 6/7fps

The D5200 can shoot continuously at 5 frames per second (fps), which is pretty good for an amateur camera, especially one with such high resolution, but the D7100 can shoot at 6fps – or 7fps in its 1.3x ‘crop mode’. This gives it a modest but significant advantage for sports and action photography.
D5200可以每秒5張連拍(fps)，對於業餘相機已經很不錯了。
特別是D5200有這麼高的畫素。
但D7100可以達到6fps -或7fps(使用1.3x裁切模式時)
這讓D7100在運動或動態攝影有更大的優勢。

8.垂直手把
8. Battery grip

The D7100 takes an optional battery grip (the new MB-D15), but the D5200 does not. This gives the D7100 an additional advantage for continuous shooting – the maximum frame rate remains the same, but with an
EN-EL15 battery fitted in the grip, it can take up to 1,900 shots between charges. The MB-D15 can also take 6 AA-size batteries. Apart from offering improved battery life, the grip makes the camera easier to hold and has an additional shutter release button and command dials positioned specifically for vertical shooting.
D7100可以額外加裝垂直手把(新MB-D15)，但D5200則不行。
這讓D7100在連續拍攝時更有優勢 -最大連拍速度維持一樣，但多一顆EN-EL15電池裝在手把裡，
讓D7100充一次電就可以拍攝1900張照片。
MB-D15也可以填裝6顆AA電池。
除了提供延長的電力外，垂持手把也讓相機握起來更順手，垂持拍攝時也有對應的快門鈕和指令盤。

9.內建閃光燈:控制模式
9. Built-in flash: Commander mode

The built-in flash unit is the same in both cameras, but the D7100 has the advantage again because it can be used in ‘commander’ mode to control other external Nikon Speedlights remotely. For most users it’s not
a must-have feature, but it could be important for enthusiasts or pros who work extensively with flash.
兩台相機的內建閃光燈是相同的，但D7100可以利用閃燈的控制模式來遠端觸發其他外接閃光燈。
對大多數使用者，這並不是一定要有的功能，但對使用外接閃光燈的玩家或專業攝影師則很重要。

10.LCD螢幕:固定式 VS 翻轉式
10. LCD display: Fixed versus articulating

Technically, The D7100’s 3.2-inch display beats the 3-inch display on the D5200. It’s larger, and it also has a higher resolution of 1,229k dots versus 921k dots. But (and it’s a big BUT), the D5200’s display is fully
articulating, making it much easier to shoot macros, movies, waist-level, ground-level and overhead shots. We say this gives the D5200 a major advantage when you’re composing shots in Live View.
理論上來說，D7100的3.2吋螢幕應該是優於D5200的3吋螢幕，
因為他比較大，也有比較高的解析度。(1,229k 點 vs 921k 點)
但是很重要的是，D5200的螢幕是可翻轉的，讓他在拍攝微距攝影、電影、接近地面和從頭上往下拍時更容易。
這點讓你在使用Live View取景時，D5200有了巨大的優勢

11.電池:EN-EL14 vs EN-EL15
11. Battery: EN-EL14 vs EN-EL15

The D5200 uses a relatively slim EN-EL14 battery, where the D7100 uses a fatter EN-EL15. We don’t have
official battery life figures from Nikon yet, but we think the D7100 is likely to go significantly longer between charges, especially if you use the Live View mode for any length of time.
D5200使用的是比較小的EN-EL14 電池，而D7100則是使用EN-EL15。
Nikon並沒有公布官方的電池壽命數據，但我們想D7100的電池使用時間應該會長很多。
特別是當你使用Live View 模式時。

12.大小和重量:
12. Size and weight: 555g vs 765g

The D7100 is very compact for an enthusiasts D-SLR, but it’s still a few millimetres larger than the D5200 in width and height, and a massive 210g heavier. Many people won’t mind the extra size and weight, but if
space in your bag is limited and you like to travel light, the D5200 comes out on top. There is a downside to
the D5200′s miniaturisation, though, in that people with large hands may find it awkward to hold and operate.
D7100對於玩家來說是功能很齊全的，但他仍然比D5200稍大一些，也重了210g。
許多人並不在意額外的大小與重量，但如果你的攝影包並不太大，而你也要輕裝旅行的話。D5200比較適合。
但D5200的嬌小體積也是有缺點的，手比較大的人會覺得D5200握起來和操控時手會卡卡的。

13.機身材質:金屬 vs 塑膠
13. Build quality: metal vs plastic

The D5200 is all plastic, but the D7100 has magnesium alloy top and back plates for extra robustness. It also has the dust and moisture seals found on Nikon’s professional cameras, so it’s going to be much better for adventurous outdoor photography in tough conditions. It doesn’t have the all-metal build of Nikon’s
professional DX-format camera, the D300s, but it’s a clear step above the D5200.
D5200是全塑膠，但D7100在機頂和機背是使用鋁鎂合金，以提供更佳的堅固性。
D7100也有和專業機相同的防滴防塵耐候性質，
雖然和全金屬的DX專業機D300s不同，但也明顯比D5200高了一級。

14.控制介面:初學者 vs 專家
14. Control layout: beginner versus expert

The D5200 has almost all the features of the D7100, but it’s designed to be much more user-friendly for
beginners or photographers who are still learning. Its interactive interface is clear and helpful, but more
experienced users may find it soon becomes frustrating because the manual settings are that little bit more difficult to get to. The D7100, by contrast, is designed more for enthusiasts. It’s easier to get to common
manual adjustments and the D7100 has two command dials not one, which speeds things up even further.
D5200幾乎有D7100的全部功能，但他對仍在學習的初學者來說，使用者介面友善很多。
他的互動式介面既清楚又有幫助，不過比較進階的使用者可能會覺得很沮喪，因為很多設定要多幾步才能達成。
D7100相較之下則更適合玩家，他在設定上更直接、簡單，D7100有兩個指令轉盤，讓操作更快速。

Nikon D7100 vs D5200:我們的想法
Nikon D7100 vs D5200: what we think

The D5200 is smaller, cheaper and more novice-friendly than the D7100. It has the same resolution and many of the same features, and we particularly like the articulating LCD display.
D5200是更便宜輕巧，相較於D7100使用起來比較友善。他們有相同的畫素及多數相同功能，
我們也很喜歡可翻轉的LCD螢幕

However, while you might not notice a huge difference in the picture quality, more experienced camera users
could quickly find the D5200’s simplified control layout quite frustrating, and the differences between the
D5200 and D7100 will become more apparent over time.
不過，在分不出明顯畫質差異的情況下，
已經玩攝影一段時間的用戶可能很快會覺得D5200簡化的操作方式很沮喪。
而且，使用一段時日之後，兩者的差異會越發明顯。

So we think that although the D5200 is a terrific camera for novices ready to try out more adventurous
photographic techniques, the D7100 is the one that true photo enthusiasts should go for. Image quality and
resolution aren’t the only factors – ergonomics, accessibility, speed and handling are more important in the long run.
所以我們認為D5200比較適合初學攝影，且想嘗試更多攝影技巧的人。
D7100則比較適合攝影玩家。
畫質和畫素並不是唯一的因素 -人體工學、配件、速度和操作在長遠來看是更重要的。
