There is no major issue, as we all know Canon all DSLR camera comes with built-in lens correction tool that corrects Peripheral illumination, Chromatic aberration and Diffraction once the shot is captured. Every Canon EOS camera have lens database inside and apply lens correction algorithm only when native Canon lenses mounted on it. Lens correction tool doesn’t work with third party lenses and the second thing don’t try to adjust focus ring while lens is on AF mode, Manual Override not available with Sigma lenses.
Thank you for purchasing and using our products.
Please find the following notes on the usage of SIGMA interchangeable lenses for EOS, when attached to Canon EOS 5D Mark IV that is released on September 8th.
MO (Manual Override) function is unavailable with this camera (Full-time Manual function can be offered).
When using a SIGMA interchangeable lens for EOS, setting the corrections to [Disable] is recommended, as “Lens Correction” functions of the camera, such as Peripheral illumination correction, Chromatic aberration correction, Diffraction correction and Distortion correction are not supported.*
* If those functions are activated, the performance of lenses may not be accurate. * This is not only for EOS 5D Mark IV, but also for other camera bodies with the same function.
We appreciate your continued support for our company and products.
Get first report here on Canon 5D Mark IV Latest Reviews, Canon 5D Mark IV camera visited DXOMark lab and as expected it’s score is above all Canon DSLRs announced till now. Dpreview also awarded Gold award to Canon 5D Mark IV.
Canon 5D Mark IV crowned as the best Canon camera ever tested at DXOMark Lab. According to DXO Mark
The significant sensor improvements over its predecessor in both resolution and dynamic range makes the new 5D Mark IV look an attractive upgrade for Mark III owners shooting weddings, events, landscapes, editorial and advertising work,” they write in their Mark IV Review Conclusion, “as well as for photographers stepping up to their first full-frame camera.
The next bench-mark test done at dpreview lab and as expected the Canon 5D Mark IV won the Gold award with 85% of score. Take a look at the conclusion below
With the EOS 5D Mark IV, Canon has further refined its semi-professional full frame all-rounder. With a solid build and improved weather sealing, faster burst speed, increased resolution, increased dynamic range, updated autofocus system and Dual Pixel live view functionality, the Mark IV will be as much camera as many people need, even if it doesn’t revolutionize the 5D-line the way its predecessors have.
Both camera are made with different approach, the Canon 5DS is high resolution Canon DSLR made for shooting in controlled light environment and perform its best when used at base ISO range (below 3200) where as Canon 5D Mark IV is the flagship DSLR of 5D series and made which can shoot perfect stills with Hybrid AF support and records 4K video.
Practically both the camera using Canon made fullframe sensor but the technology used inside them are completely different, the Canon 5D Mark IV uses Dual-pixel CMOS AF sensor that can do fast AF while recording video or shooting with live-view model. Not only that, other brand users should also understand that the camera doesn’t have any dead pixels inside the sensor to do AF. The Dual-pixel AF technology uses to sub-photo diodes to acquire AF and hence your sensor doesn’t have any single dead pixels.
If you look at the ISO range of the current Canon 5D Mark IV, its much improved compared to the Canon 5DS camera. The standard ISO range of the Canon 5D Mark IV as well as the expandable ISO range both are better.
The Canon 5D Mark IV features 30 MP FF sensor whereas the Canon 5DS features 50MP FF Sensor, more megapixel on the same sensor plane means smaller photodiodes. When the sensor Photodiode becomes small it become less sensitice to light. Canon 5DS camera is not made to perform in low-light environment. It does need a well controlled environment to deliver optimal result.
Advance AF System :
The new Canon 5D Mark IV system uses touch and shoot / track technology with the help of High Speed Dual-Pixel CMOS AF system.
The Canon 5DMark IV DSLR uses two different types of AF system
Dual-pixel CMOS AF Sensor for Fast AF during still and video
61 Point Phase AF module 41 cross-type (f/8 support at all points)
The Canon 5D Mark IV features advance Phase AF module whose All 61 point AF system is compatible with F8 aperture whereas Canon 5DS center point only support F8 aperture. The other major advantage Canon 5D Mark IV is Dual-Pixel AF system that enables super fast AF while shooting with live-view or video. The Canon 5DS features a contrast detect sensor AF become slow and sluggish when you s them for shooting in live view or video.
Canon 5D Mark IV
4096 x 2160 (4K), 1920 x 1080 (Full HD), 1280 x 720 (HD)
1920 x 1080 (Full HD), 1280 x 720 and 640 x 480
The Canon 5D Mark IV can shoot 4K videos on the whereas the Canon 5DS remain limited to Full HD mode only. The Canon 5D Mark IV record 4K video with an ideal 1:1 pixel sampling ratio and while recording Full HD video it uses the entire Full frame sensor. The 4K video is recorded using a central 4096 x 2160 area of the sensor at a 1.74x crop so there is still a lot of space of improvement left for Canon 5D Mark IV camera. BTW, it is better than Canon 5DS.
The Canon 5D Mark IV feature built-in WiFi and NFC connectivity as well as GPS module. The NFC also allow you to enable remote shooting from your smartphone. The camera also compatible with CS100 Connect Station.
Conclusion: We highly recommend you to get the Canon 5D Mark IV camera, the camera features new sensor, advance AF system and a option to record 4K videos. Canon also introduced Dual-Pixel AF mode, that allow photographers to fine tune AF after the shot is taken.
Canon 5D Mark IV vs Canon 5D Mark III Canon announced 5D Mark 4 camera just while ago and we are here to compare it with its predecessor Canon 5D Mark III.
We have carefully selected only those points who can show the actual difference from its predecessor for example effective pixels, dual pixel-raw and while using a F8 aperture. Now let’s look at the comparison below.

Canon developed entirely new sensor for its 5D Mark 4 camera. Without compromising with the sensitivity of a camera canon added 30MP full frame CMOS sensor with dual pixel CMOS auto focusing system to enable fast AF during video and still shooting. The standard ISO sensor of range of 100-32000, which can be expanded to ISO 50-102400.
Dual pixel RAW
If you shoot images in Dual-pixel RAW mode then while editing in canon dp pro software you get two options, micro-fine tune AF adjustment and Bokeh shift. More details here Understanding Dual-pixel Raw
AF points at f/8
Up to 61 points / 21 cross-type AF points (all individually selectable)
AF points at f/8: Canon 5D Mark IV 61 AF points as well as 41 cross type are compatible down to F8 aperture and also works down to EV-3. Whereas, the Canon 5D Mark III only 1 AF point was active when you have selected F8 aperture.
Canon 5D Mark 4 camera features contrast detect CMOS sensor so there is no chance that it can compete with the recently announced Canon 5D Mark 4 camera with dual pixel CMOS AF Technology.
Canon 5D Mark IV features Continuous Shooting mode of 7 frames per second @ 30 MP. whereas, the Canon 5D Mark III remains limited to 6 frames per second @ 22.3 megapixel.
Burst while using live view display, Canon 5D Mark IV camera can shoot 4.3 fps burst while live-view is ON and it will do continuous AF without and issue.
No 4K video recording option available in Canon 5D Mark III. The Canon 5D Mark IV is able to record 4K video at Digital Cinema (DCI) standard 4K (Motion JPEG) videos of 4096 x 2160 pixels at up to 30 or 24 fps. The Canon Dual Pixel CMOS AF sensor inside the EOS 5D Mark IV enables touch AF while recording 4K video. EOS 5D Mark IV is equally able to shoot Full HD video at up to 60p plus HD at frame rates as high as 120p, ideal for smooth slow-motion video.
Canon 5D Mark IV vs Sony A7R II vs Panasonic GH4 High ISO Video test done between all these three ultra-popular camera. Before we begin just take a look what Tony said about the test
If video usability is important to you, we recommend the GH4. If video quality is more important, get the a7R II or even better, the A7S II. Order the 5D Mark IV at (though clearly not for its video capabilities)
I always look test videos carefully before I publish them to my blog. So, while looking at the 5DMK4 latest test video I always noticed the Canon 5D Mark IV sample is more sharp (at 100%) compared to Sony A7R II and Panasonic GH4. Why?
It may be due to several reason, type of lens used or may AF was not set on tony face, whatever. But again, if I look at the test video 5DMkIV sample look more sharp and usable.
Take a look at the sample images captured by Canon 5D Mark 4 camera, these sample images are generated from a newly developed 30.4 megapixel dual pixel CMOS sensor powered by a dual Digic6 + image processor.
The sample images look very stunning and absolutely flawless
