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.

Nikon Silent AF Patent More Details
(Description of the silent mode)
Lens control unit of the present embodiment, the control of the lens driving unit performs based on the two kinds of control modes (normal control mode, the silent control mode). If the lens control unit is the normal control mode is set, the lens control unit 203 controls the lens driving unit 212 without limiting the driving speed of the focusing lens. On the other hand, if the lens control unit silent control mode is set, the lens control unit drives the speed of the focusing lens controls the lens driving unit so as not to exceed a predetermined maximum drive speed. More specifically, in the control of the lens drive unit monitors the driving speed of the focusing lens detected by the lens speed detector, the detected driving speed is not exceeded the maximum driving speed of the .
List of patents surfaced over the web that shows up the list if lenses Canon working in for their fullframe Mirrorless cameras lenses. We have already published the list of upcoming Canon lenses 2019 back on January 2019.
Canon RF Lenses Patent Details
Canon 85mm f/1.2,
Canon 100mm f/1.4,
Canon 24-70mm f/2.8, and
Canon 28-85mm f/2-2.8
List Canon upcoming lenses already have 85mm F1.2 L name.
Canon already showed us upcoming 6 RF Mount lens images, now in the patent above we have 2 brand new lenses name. ( Canon 28-85mm f/2-2.8 and 100mm F1.4). So, probably these two lenses are coming in 2020 or later.
Some of the models of Ricoh GR series camera have wobbly control dial/pad. That may upset some users, that’s why Ricoh is calling back set of affected units. If your Ricoh GR III camera falls under the serial number mentioned below, you may have wobbly control dial/pad in your GR III camera.
The affected serial numbers are:
0010046 to 0022290
2010043 to 2012044
3010045 to 3010544
4010041 to 4010230
Take a look at what Ricoh said
“The basic specification is to set a slight rotation allowance width, but as a result of investigation, it has been found that some products with the following target serial numbers have combinations with large display inclinations.”
Take a look at the official Press Release
Notice to Customers of Compact Digital Camera “RICOH GR III”
Thank you for always using our products.
Recently, some of the customers pointed out that the cross key on the back of the main unit of the compact digital camera “RICOH GR III” on the market is tilted.

Anyone comparing the Sony A6300 and A6400 will find the results intriguing. Although the two models share a similar sensor resolution (pixel count) and the overall results are very close, the measurements are not identical.
Despite its slightly higher noise floor over the A6300, the new A6400 sensor performs well, combining a wide dynamic range over a highly useful range of ISO sensitivity settings and excellent low-light ISO capabilities. Although that directly impacts the color depth, the A6400 remains capable of delivering extremely pleasing images. Combine those attributes with the new AF system, 11fps continuous shooting, and a relatively affordable price, and you have a very enticing camera for sports and action photographers on a budget.
In this review, we have compared the Sony A6400 to its predecessor and to its most relevant rival from other another brand. As usual, you can create your own comparisons and in-depth analyses using our interactive image sensor ranking tool.
Nikon DSLR patent spotted with Built-in Image Stabilization, yes I am talking about introduction of sensor shift image stabilization in DSLRs. So, in near future Nikon DSLRs will have both Lens and Image based stabilization.
PROBLEM TO BE SOLVED: To prevent deterioration of shake correcting performance due to an error.SOLUTION: A shake correcting device comprises: an angular speed sensor 12B for detecting angular speed of a camera; an acceleration sensor 12A for detecting acceleration of the camera; a posture computing portion 32 for computing the posture of the camera, on the basis of output of the angular speed sensor and the acceleration sensor; a correcting portion 21 for correcting the output of the acceleration speed sensor, on the basis of a computing result of the posture computing portion; a control portion 35 for controlling shake correction, on the basis of an acceleration signal after correction by the correcting portion and an angular speed signal from the angular speed sensor; and a determining portion 51 for determining reliability of an initial posture of the posture computing portion. The control portion makes weight of the signal based on the acceleration sensor heavier (S9), when the determining portion determines that the reliability of the initial posture is low (YES in S7).
I was really amazed to see with the help of FTZ adapter the Nikon Z6 camera was working in collaboration with Nikon VR (Optical Image stabilization) system. After activating the Lens based VR the overall image stabilization of the camera unexpectedly improved, you can see for yourself.
Nikon Should Add VR to S-Line of lenses
After watching this video I recommend and hope that Nikon will soon add VR (Vibration reduction) tech to their future S-Line of lenses. Since, the camera they have made support DUAL IS feature. The Nikon Z6 and Nikon Z7 share same Image stabilization module inside, so there is no doubt that Nikon Z7 will also work in collaboration with VR lenses.
