We have already published a patent that Nikon working on 18-135mm APS-C Mirrorless lens with Silent AF Motor. Now, we have one more patent that clearly says Nikon is working more to improve the AF noise generated by the lenses by limiting the AF speed of the AF motor.
Nikon APS-C Mirrorless to have Silent Mode and Normal AF Mode
Don’t get confused with DSLRs in camera silent mode, for example I have used Nikon D850 DSLR silent mode in which camera uses the electronic shutter to capture images and same in the case of Nikon new Z6 and Z7 Mirrorless camera, if you select silent mode in nikon Z7 camera the shutter slap noise will be reduce while using electronic shutter, however in LED light lights some banding issues may appear while using silent shutter.
The new patent reveals silent AF Mode, in Silent AF mode camera will limit the AF speed to minimize the noise of the AF motor.
The silent AF lenses coming for Nikon APS-C Mirrorless camera and very soon the tech will be also implemented in FF Mirrorless camera.

Canon latest patent suggest that Canon is working on a new Version dual pixel CMOS autofocus sensor, that particular sensor is capable to do multishot in a single click with the help to sub-pixels. With the help of the subpixel multi-shot technology the Canon dual pixel CMOS autofocus sensors will going to create images with high dynamic range compared to the conventional image that you get from a Canon DSLR camera / Mirrorless Camera.
As we all know Canon dual pixel CMOS autofocus sensor uses their to sub pixels to acquire auto focus on subject, now in this case that to sub pixels or may be in quad pixel sensor a pair of pixels will capture two different images at the same moment with different exposure values. And later on both of the image will going to be combined with each other to have a image with enhanced dynamic range.
As you can see from the flowchart, Canon algorithms are arranged in a way to acquire different images with multiple exposures and then perform the first dynamic range extension process and after that transform II dynamic range extension process and finally the images saved in the memory card.
So any future Canon will going to give a option to users to have images with enhanced dynamic range. There is also possibility that can and may seamlessly integrate this feature in their dslrs, because in many test we have seen that Canon dslrs get low scores when compared to the cameras from Nikon or Sony.
In general a patent takes approx 1 or 2 years of time to become a official product, and it is also not necessary that every parent should become a product. SO, at this moment we are unable to confirm you that this particular Technology will going to be used in a future inside Canon DSLR or upcoming Canon mirrorless camera. But we do have a high hope as this one is most important feature that should put inside the Canon DSLR and upcoming cameras.

Nikon D650 Arrival Confirmation ?
We all know that Nikon D650 camera is 4+ year old, completely outdated and desperately waiting to be replaced. Surprisingly Nikon D750 sales volume is still good according to online retailers. And if Nikon goes on schedule update of their DSLRs as they have done in past, then for sure Nikon D650 announcement is next few months. We will not going to talk much about the core specification of the upcoming camera but for sure we will going to see introduction of 4K Videos in Nikon entry level DSLRs. It’s already too late but as they say, better late than never. Hybrid Sensor in DSLR? Well Nikon is working on their own customized versions of DualPixel CMOS AF sensors as we have seen the recent patents, So it is possible that we may see Nikon first Hybrid Sensor based DSLR soon or they will save Hybrid sensors for upcoming Fullframe Mirrorless cameras. It all depend upon Nikon. 
Other Possibility – Nikon Fullframe Mirrorless ?
It may be possible these two or possibly one of them are mirrorless model, and they will going to use similar batteries EN-EL15a as power source. As we are getting continuous set of information from past that Nikon is gearing up announce their first Fullframe Mirrorless models this September, on or just prior to Photokina event.
