7d Mark Ii Low Light Performance

by -42 views

The EOS 7D Mark Two, launched after about 5 years of development in the background, boasts specifications superior to the EOS 7D in well-nigh every style. Steady progress has been accomplished. How do the various upgraded functions alter the actual shooting environment? In this serial, nosotros will explore the hidden capabilities of the EOS 7D Marker II from eight unlike points of view. Part three sees usa comparing the camera’s resolution, ISO speed, and low-low-cal ranging limit. (Study: Ryosuke Takahashi)

CHECK 4: Resolution

What does a difference of about 2.two megapixels hateful?

Testing method

Gear up the camera on a tripod and attach the EF-S18-135mm f/3.five-v.6 IS STM and EF70-200mm f/2.8L IS II USM to the photographic camera. Focus on the scenery in the distance and shoot using Discontinuity Priority AE at different discontinuity values. Check how high the resolution is at the wide-angle end (xviii mm, lxx mm) and the telephoto end (135 mm, 200 mm).

At 70 mm, the delineation of the tiles and trees is reproduced in greater particular on the EOS 7D Mark II. At 200 mm, the divergence in the depiction is non every bit perceptible.

The EOS 7D Mark II is improve at reproducing fine details

The EOS 7D Marker II is equipped with a new CMOS sensor with an constructive pixel count of approximately 20.ii megapixels. This is college than that of the EOS 7D by almost 2.ii megapixels. The basic structure of both CMOS sensors also differs. E.g. The EOS 7D Mark II is equipped with a dual pixel CMOS AF sensor. Because the sensor size is the same, the EOS 7D Mark II has a smaller pixel size. A number of bug accept as well been resolved past introducing a college discontinuity ratio in the photodiode, a new refinement process and depression profile engineering science. If you exam the resolution, no large difference appears in telephoto shooting with a loftier magnification gene. However, when shooting wide bending scenes with a low magnification factor, the EOS 7D Mark II is improve at reproducing the fine details in terms of the image quality. In particular, the improvement in the resolution is significant for subjects that consist of fine lines.

Bank check 5: High ISO Speed

What is the difference in the quality and level of dissonance?

Testing method

Fix the camera on a tripod and attach the EF-S18-135mm f/three.5-five.6 IS STM to the camera. Focus on the scenery in the foreground and shoot using Aperture Priority AE (f/11) while changing the ISO speed. Apply the default settings for the various settings used in dissonance reduction. Check the noise level and quality.

EOS 7D Mark II – Multi Shot Dissonance Reduction

When shooting at high ISO speed with the EOS 7D Mark II, setting dissonance reduction to [Standard] suppresses the colour noise. In addition, the [Multi Shot Noise Reduction] function makes the luminance noise (black and white specks) even lesser. This is the difference in performance that time brings.

The EOS 7D Mark 2 delivers vastly superior loftier ISO speed image quality

The basic characteristics of the image sensor and the image processing engineering determine the image quality when shooting at high ISO speed. These are subject to the most changes over time in digital cameras and even a menses of near 5 years is considered a very long fourth dimension. Besides having a dual DIGIC vi paradigm processor, the EOS 7D Mark II is likewise equipped with [Multi Shot Noise Reduction], making information technology worlds apart from the EOS 7D. In terms of the basic performance, the EOS 7D Mark II enjoys a marked advantage over the EOS 7D when shooting at a normal ISO speed of 16000 that rivals the [Standard] setting when shooting at ISO 6400 on the EOS 7D. Moreover, due to [Multi Shot Noise Reduction], the image quality of a shot taken at ISO 16000 with the EOS 7D Marking 2 is the same as a ISO 3200 shot taken with the EOS 7D. In other words, the EOS 7D Mark II has a capability that is about two steps higher in total than that of the EOS 7D.

CHECK 6: Low-low-cal ranging limit

Which AF works better in dark areas?

Testing method

Use an incident light meter to measure the brightness and set the exposure from ±0EV to −3.0EV. Stick a black and white chart onto a wall. Then, focus on the border of the nautical chart with the primal AF point and bear out ranging x times at a focusing range of infinity. The AF will role and will produce a “beep” sound once the picture is adamant to be OK. Fix the photographic camera on a tripod and use EF70-200mm f/2.8L IS Two USM for the lens.

The AF on the EOS 7D Marking II is more stable, with markedly less instances of losing focus The focusing time is besides shorter compared to the EOS 7D, allowing y’all to focus accurately even from a very blurred country.

The difference in true adequacy emerges in the central AF point

The EOS 7D Marking II’s low-lite ranging limit is −3.0EV (f/2.8 sensor) for the fundamental AF point, surpassing the values of −0.5EV on the EOS 7D and −2.0EV on the EOS-1D 10. The peripheral AF points can likewise adapt to a brightness of −0.5EV. This effigy is also higher than that on the EOS 7D. When a test was conducted, the EOS 7D Mark Two, as expected, came out strong when shooting in nighttime areas, achieving a perfect focus upwards till −2.0EV. It is difficult to make out a subject even with the naked centre at a effulgence of -three.0EV just the EOS 7D Mark 2’s AF managed to work well in such a condition. However, in order to draw out this operation, it is necessary to use the f/2.8 cantankerous-type sensor. Therefore a lens brighter than f/ii.8 needs to be used. The obvious differences between the two cameras clearly demonstrates the capabilities of the new AF sensor.

*This design was produced using a prototype model. As a result, please note that the bodily product may differ in terms of the appearance, image quality, etc.
