So sánh ảnh nikon d7100 vs d700 năm 2024

Mình nhận được nhiều lời để nghị so sánh chất lượng ảnh, iso giữa hai chiếc máy Nikon D700 và Nikon D7200. Để đáp ứng nhu cầu mình đã chụp một số ảnh trong cùng điều kiện, cùng một ống kính. Do hai chiếc máy cách nhau quá xa về công nghệ. Mình sẽ bỏ qua phần so sánh màn hình, lấy nét hay các tính năng trong menu mà đo vào so sánh chất lượng ảnh, khả năng khử nhiễu. Các cài đặt trên hai máy hoàn toàn giống nhau và sử dụng ống kính Nikon 35mm f/1.8 G DX. Mình sẽ bình luận ít, để các bạn tự đưa ra đánh giá riêng.

ISO 100

Do độ phân giải hai máy là 24:12 nên khi Zoom 100% sẽ có khác biệt về độ lớn của chủ thể trong hình khá nhiều.

Như vậy là mình đã so sánh các mức ISO từ thấp nhất, tới cao nhất của hai chiếc máy D700 vs D7200. Bây giờ mình sẽ so sánh thêm ảnh RAW của hai máy, trong trường hợp dư sáng, thiếu sáng. Để chúng ta thấy được sự khác biệt về chất lượng ảnh, tiềm năng hậu kỳ trên file raw của hai máy này.

Qua phần so sánh này, các bạn có thể thấy Nikon D7200 với cảm biến Crop 1.5X , độ phân giải gấp đôi so với Nikon D700, nhưng lại có chất lượng ảnh chẳng mấy kém cạnh so với Nikon D700. Màu sắc thể hiện chính xác ngay cả với các mức ISO cao tới rất cao, trong các trường hợp dư sáng, thiếu sáng.

Nếu bạn đang định đầu tư một chiếc máy, cần gọn nhẹ, lấy nét tốt, màn hình tốt thì Nikon D7200 là một lựa chọn sáng giá. Còn bạn vẫn muốn lựa chọn một chiếc Nikon D700 để sở hữu một cảm biến Full Frame thì hãy tìm một chiếc máy thật tốt, tránh trường hợp mua phải máy bị dựng. Mình có để ảnh gốc của hai máy phía dưới, các bạn có thể tải về để so sánh được chi tiết hơn. Cảm ơn.

The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.

A higher screen resolution provides a sharper image, making it easier to review your photos.

The focus motor moves the lens in order to autofocus. For system cameras, having a focus motor in the camera's body allows you to use a wide range of lenses, including lenses which do not have their own focus motor. For compact cameras, a focus motor is usually built-in.

Flip-out screens can be useful for tricky shots.

With 100% coverage, you can compose the image correctly when you capture the photo. With less than full coverage, you may have to crop your photos afterward to get them looking perfect.

The size of the screen (measured diagonally).

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.

Optics

One of the most important aspects of a camera is the size of its sensor. A larger sensor will capture more light, which results in improved low-light performance, dynamic range, and general image quality.

The more focus points the more flexibility in picking which part of the scene to focus on. They also give the image sensor a better probability in identifying the right area of the scene to focus on in more automatic modes.

The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image.

With a higher light sensitivity (ISO level), the sensor absorbs more light. This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash.

Expanded ISO allows you to go beyond the native ISO. It does this by digitally enhancing the image output. The resulting image will have less quality than when staying within the native ISO range, but it can be useful in certain situations.

With sensor shift, the image sensor (rather than the lens) moves to counterbalance any vibration of the camera. This means the image will be stabilised regardless of what lens is being used.

Fast continuous shooting is useful for catching action shots.

With AF tracking, once you choose the subject and press the shutter release part way down, as the subject moves, the autofocus will follow it. No more out of focus shots.

Videography

The maximum resolution available for videos shot with the main camera. Although it may be possible to choose among other frame rates, those recordings usually have lower resolutions.

A phase-detection autofocus system is faster than a contrast detection autofocus system. Even when recording scenes with a lot of fast movements, the videos are sharp and clear.

When recording movies they stay focussed and sharp.

A microphone port allows connecting external high-end or specialized microphones.

With a standard mini jack socket, you can use the device with most headphones.

A stereo microphone allows to record audio files or movies in stereo without an external microphone.

A timelapse shows a long passage of time sped up. A series of photographs taken from the same position over a long period is joined together to create a short video. It is great way to capture things like the setting sun, or clouds moving across the sky.

The higher the movie recording bitrate the better the movie quality with more and crispier details and less compression artifacts.

More microphones result in better sound quality and enable the device to filter out background noise.

Battery

CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.

The battery is removable and can be replaced by the user if broken.

The battery can be recharged and used over again.

An indicator shows you when the device has low battery.

Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. More battery power can be an indication of longer battery life.

Features

The device can connect to Wi-Fi.

Bluetooth is a wireless technology that allows you to easily transfer data between different devices, such as smartphones, tablets and computers.

It has two memory card slots, allowing you to store more photos without switching cards. This is particularly useful on long shoots when you need more space.

The camera can take a series of shots, shifting the sensor slightly with each one. These can then be combined to create an extremely high-resolution image. It’s particularly useful for things like photographing artwork.

A raw image file contains minimally processed data from the image sensor. Raw files are so named because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor.

It is capable of shooting stills in a lossless compressed raw format. This has all the advantages of shooting raw, while taking up much less storage space. The smaller file size also allows quicker read/write speeds.

The Wi-Fi versions supported by the device.

This technology allows the users to use their smartphone as a remote control for the device.

Devices with a HDMI or mini HDMI port can transfer high definition video and audio to a display.

Miscellaneous

pixel density

Pixel density is a measurement of a screen's resolution, expressed as the number of pixels per inch (PPI) on the screen. A higher pixel density translates into more clarity and sharpness for the images rendered on the screen, thus improving the quality of the viewing experience.
