Canon EOS 5D Mark IV Full Frame Digital SLR Camera


30.4MP CMOS image sensor: this feature makes the camera full frame with the sensor being the equivalent of a 35mm film frame. The camera therefore features a high resolution and shooting can take place in a wide range of environments.

ISO 100-32000: this ISO is expandable up to 50-104200. This range is ideal for low light photography.

4K motion JPEG video: this camera captures Digital Cinema (DCI) standard 4K of 4096 x 2160 pixels at up to 30 or 24 fps. It can shoot Full HD video at up to 60p and HD at up to 120p. The 120p is ideal for slow motion videos. The camera supports MOV and MP4 formats.

DIGIC 6+ image processor: this feature increases in-camera functions. This ensures fast operation, high image quality, high 4K video recording, reduces noise and enables correction to take place.

3.2-inch LCD display: this is a 1.62 million dot low reflective LCD monitor. It ensures bright and sharp display while shooting.

7.0 fps continuous shooting: the shutter, advanced AF and exposure, and image processing functions ensure performance up to 7.0 fps.

61-point AF: the 61-point High Density Reticular AF II system features 41 cross-type points and a wide AF area. This feature also allows wide subject tracking ensuring that all the action is captured. It also has Canon’s AI Servo AF III which recalls the AF’s path in order to refine precision shot to shot.

Intelligent Scene Analysis system: this feature is important for fool-proof performance.  It uses its own RGB+IR light sensor of about 150,000 pixel resolution. It instantly provides a deep image analysis and makes corrections in the process. The sensor enables the anti-flicker function and ensures that a photo is captured when the subject most likely well illuminated.

Dual pixel CMOS AF: this feature enables the camera to capture Dual Pixel RAW (DPRAW) files. Several options for adjustment are available when such files are processed with Canon’s Digital Photo Professional image processing software. With this software you can adjust pixel level, refine still photos, micro adjust images to maximize sharpness in detail areas, bokeh shift for soft focus and reduce ghosting. There are also in-camera correction options such as peripheral brightness, chromatic aberration, and distortion and diffraction correction.

Built-in Wi-Fi: the camera’s aperture, shutter speed, ISO, focus and shutter can be operated wirelessly from a compatible iOS or Android device. This is done using the free Canon connect app. Once you have installed the app in your device, you can remotely control the camera from a distance. This is a great option for difficult shots.

Built-in NFC: with this camera you can easily transfer images and videos to a compatible Android device

Built-in GPS: A user can tag GPS coordinates to an image which helps in recalling locations. It also includes auto time syncing with Universal Time Code (UTC) through satellites.

Frequently asked questions

Q: Will the battery pack fit while using a tripod?

A: Yes, it will. I always mount the lens directly on the head, unless it is a small lens. This is much more stable than mounting the camera and it is convenient to flip form vertical to horizontal.

Q: Which Lightroom does it support? LR6 or LR CC or both?

A: I know it works with the latest LR CC. but I have also heard that it can work with LR 6.7 though I have not used it myself.

Q: Does this camera have a built-in flash?

A: No.

Q: Is the 61 point Auto Focus enough for wildlife photography?

A: Yes. The 61 point AF is great for wildlife especially swarms of insects and its sensor works really well in low light.

This review is inspired by my experience as an advanced photographer who records videos frequently. I previously owned a 5D Mark III and the upgrade was a matter of choice and not limitation. The Mark III has served me really well for three and half years. After using the Mark IV for a month, I feel that I know enough to give my opinion.

The camera’s controls were much like my camera so I had an easy time getting used to it. The shutter is quieter, the touch screen is amazing, the viewfinder phase detect AF fulfilled my expectations, and the dual pixel AF was fast as described. I found that for a heavy camera, you might perhaps consider using smaller lenses.

I definitely noticed the additional resolution pixels when it came to the image quality. I also noticed that shooting in JPG offers a range of options. It also gives lower resolution modes.

The dynamic range is greater than that of III. I also loved the availability of AF when filming. This has encouraged me to shoot videos more often. I rarely use the 4K which has great quality but it takes a lot of space and a lot of time to process.

Overall, this is a great camera although it is a small upgrade from the 5D III. However, you will definitely enjoy shooting with this camera, both stills and video. The dual pixel AF will certainly encourage you to take more videos. You will also enjoy the GPS feature, intervalometer, touch screen and Wi-Fi.

Sony Alpha a7S Mirrorless Digital Camera


35mm Exmor CMOS image sensor: this sensor works with the BIONZ X image processor. It also has 15.3 stops dynamic range.

12.2MP sensor: this camera has direct pixel readout which makes use of the completer width of the full frame camera without line skipping or pixel binning. This camera also shoots in both 4K and HD.

High ISO: this camera shoots at a high ISO of up to 409600.  It has fast intelligent AF system that greatly enhances AF sensitivity in light as low as EV-4

Gapless on-chip lens design: the new generation RGB color filter increases the sensor’s light collective efficiency. The gapless on-chip lens design, light concentration technology, and photodiode expansion technology offers high sensitivity and reduced noise levels with high dynamic range in any light condition. AR coating on the seal glass over the sensor reduces ghosting and flare.

Full HD and 4K QFHD: this camera can output 4K video to an external third party through HDMI.

50Mbps: this camera supports XAVC S, AVCHD, and MP4 codecs. The XAVC S format records Full HD recording at 50mbps. The camera records at (1920×1080) at a frame rates straight to a compatible memory card of 60p, 60i, 30p and 24p.

Frequently asked questions

Q: Is it possible that with a future firmware upgrade, this camera can record 4K? Or is the internal hardware too limited for such an upgrade?

A: I do not think it will be added. This camera and the Atomos Shogun are too cheap for 4K. I own this camera and I recommend it. It really is such a great camera. I compared it to my friend’s GH4 and my 1080p looks better than his 4K footage.

Q: Is this camera compatible with PAL OR NTSC?

A: It is compatible with NTSC.

Q: UHS-1 or UHS-3? Which of these cards is the minimum for video? I am aware that you require at least a 64GB card.

A: UHS-1 95mbsis your minimum so long as the card can hold 60mb write speed and no less. The UHS-3 is a much better choice as the write speed is guaranteed. However, there are UHS-1 cards that can do it too. They are expensive but the memory is worth it.

Q: What comes with the camera’s body?

A: The camera comes with: 2 x NP-FW50 Lithium-Ion Rechargeable Battery, Battery Charger, AC Adapter, Micro USB Cable, Body Cap, Shoulder Strap, and Cable Protector.

I am a professional wedding photographer and videographer. I had lots of experience with different cameras with my present favorite being the Nikon D800 at 36MP.

When I heard about the a7S I was very much tempted. There was a lot of hype about it but dropping from 36MP to 12MP seemed too much for me. But all other features such as the ISO, 120fps 720p video and 15 stops dynamic range made me overlook the reduced megapixels.

So I carried this camera to its first job along with a 5D Mark III hoping to shooting with it. I had never used a mirrorless camera before and this was a pleasant surprise. The menus were easy to figure out. I shot video and the results were great. The images were also clean. The 50mb enables large latitude. The camera worked really well during the day as well as at night.

Later, I explored the menu further and I was glad to find out that the buttons are customizable. In case you have several features that you often use, simply map 1 to 33 custom buttons to do it. This saves you the time of going to the menu. I also shoot in RAW and the images are great. The dynamic range is great and so is the accuracy. There is also no noise which is great. The 12MP is fine for average print. However, for enlargements you might require to use Photoshop.

The OLED EVF and LCD are great. The EVF has a sensor that knows when you are looking through so that it switches from LCD to EVF. There is also an option to do the switching manually. I am definitely impressed with this camera.
