Canon EOS 5D Mark IV

Introduction :

The Canon EOS 5D series is arguably one of the most recognizable camera lines of the digital age and the Mark IV is designed to appeal to the same wide range of enthusiasts and professionals. Nearly identical-looking to its predecessor, it receives substantial upgrades under the hood, including: a higher-resolution sensor with Dual Pixel autofocus, 4K video capture, an upgraded AF system, a touchscreen, improved weather-sealing, built-in Wi-Fi/NFC, an interval timer and GPS. All this adds up to a camera that fits into Canon's product line nicely as the all-around full-frame option.

It is built around a new 30.4MP CMOS sensor and uses the Digic 6+ processor. The AF system is from the flagship 1D X Mark II and contains 61 AF points (41 of which are cross-type) with up to 24% expanded vertical coverage compared with the system in the Mark III. The center point is sensitive to -3EV in One Shot (AF-S) mode (in Live View the sensor is sensitive to -4EV with a fast lens).

4K video capture is a welcome addition to this camera and users can record in either 24 or 30p, albeit with a 1.64x crop. All footage is captured as Motion JPEG. Additionally, the camera allows for 4K Frame Grabs, effectively giving users 30 fps stills shooting with (Dual Pixel) AF.

While developing the IV, Canon says it sought feedback from 5D-series users and found that dynamic range, resolution, AF precision and AF speed were the four most important areas improvements were requested. On paper, the Mark IV seems to address these aspects nicely.

Canon 5D Mark IV Key Specifications

• New 30.4MP CMOS full-frame sensor with Dual Pixel AF
• DCI 4K 30/24p video using Motion JPEG + 4K Frame Grab
• 61-point AF system with 41 cross-type sensors (center point sensitive to -3 EV)
• Dual Pixel AF (sensitive to -4EV) for continuous Servo AF in stills (first for a full-frame Canon camera) and video
• ISO 100-32000 (expandable to 102400)
• 7 fps continuous shooting
• Dual Pixel Raw (image microadjustment, bokeh shift, ghosting reduction)

• 1.62M-dot 3.2" full-time touchscreen
• Wi-Fi w/ NFC + GPS
• Built-in bulb timer interval timers
• Improved weather-sealing

The 5D Mark IV also has some new tricks up its sleeve including Dual Pixel Raw, a nifty option that can prove useful in specific shooting scenarios. It works by recording two 30MP images, one from each of the 'left-looking' and 'right-looking' photodiodes at each pixel. Previous Canons have combined these two signals at each pixel, but Dual Pixel Raw gives you the option of keeping them separate. This results in a file that's twice as large, but one that allows for 'image micro-adjustment,' 'bokeh shift' and ghosting reduction in Canon's supplied Digital Photo Professional software.

The iphone 7 and 7 plus

The iPhone 7 and 7 Plus are undoubted the most controversial phones Apple has ever made. You’ve probably heard that Apple killed the headphone jack on their latest smartphones, but that shouldn’t be the biggest story about the iPhone 7. Instead, the iPhone 7 should be seen as a window into how the next iPhone will look and behave.

Physically, the iPhone 7 Plus is nearly identical to the iPhone 6s Plus except for its lack of a headphone jack and the addition of dual camera lenses. Although the design is now effectively two years old and no longer as striking as it once was, it’s still a handsome if somewhat generic-looking phone.

here’s no getting around the fact that the iPhone 7 Plus is a big phone, even compared to its 5.5-inch competitors. Although it has the same size screen as my OnePlus 3, it feels much bigger in the hand because of its relatively large bezels around the screen.

Although bulky, the good news is that the iPhone 7 Plus is built like a bank vault. The phone feels extremely solid, although slippery, with no case on. There’s no play pressing the power or volume buttons, which offer a satisfying tactile click
