Cctv Manual

[Danny Hosford]

I own Nikon D7000 with 18-105mm lens. I am bit confused how the auto focus and manual focus switching works, particularly with my gear. The confusing part is both the camera and lens have an A-M switch.

I am not sure if when I have to switch to manual mode I need to shift both the buttons, on lens as well as camera? And do I have the liberty to fine tune the focus by turning the focusing ring while both camera and lens are on "A" position? Will it cause any damage to body or lens?

Based on the description from your lens, it appears your lens has what is known as FTM or full time manual focus. In an automatic focus lens, there has to be a link between a motor and the focus element. In cheaper lenses, the connection is left all the time and trying to manually turn the ring while in auto focus can and will damage the gears or the motor that drives the auto focus. The A/M switch (on the lens) manually disconnects the auto-focus motor.

In more expensive lenses, the motor disconnects from the focus elements when not making adjustments and thus you can make manual adjustments any time that the motor is not trying to make adjustments. I don't know what it is called on Nikon bodies, but on Canon bodies, you want to make sure that you are in One Shot focus mode (where the camera only adjusts the focus once and doesn't try to follow the target). On your camera body, it appears to be the AF-S auto focus mode. If you use a mode that tries to follow the target, the motor will constantly be fighting your attempts to manually focus and damage may occur.

Simply flipping the switch on the lens to M should inform the camera body that you do not wish to use automatic focus and even if the body tried to make adjustments from it's own switch, the lens would simply ignore them since the motor is disengaged from the focus element. In the event that it is an older screw-drive type lens that is driven by the camera body, then the switch on the camera body itself would tell the camera not to try driving the motor mechanically, but on a lens with the motor in the lens, I would guess it wouldn't do anything. (I'm a Canon guy, so hopefully one of the Nikon guys can confirm this.)

Personally, I love full time manual lenses and almost never put them in manual focus mode. There isn't really any reason to do so when you can get the best of both worlds. The only reason I can see to do so would be if you were unable to easily switch the AF mode to not try following focus (on my camera, it's only a button press and a wheel turn away.)

In short, it sounds like with your lens, using the camera on AF, the AF-mode set to AF-S and the lens set to A, you should be able to half depress the shutter and then make manual adjustments to the focus just fine.

D7000 Manual (p99) clearly states that having the lens on "M" while having the body on "AF" can cause damage to the camera. It does not say in what order the switches should be set so the safest procedure might be to turn the camera to the "off" position while setting the two switches.

I don't own a cell phone but do download all my manuals to a Netbook for use while traveling. All of the manuals are in PDF format so I suspect that if your phone can open a PDF you should be able to download & read them.

Thanks for your quick reply. I was on the phone with tech support the other day and I thought he mentioned a way to save the manual as an iBook on my phone and that I could learn how to do that from the Canon website. I've checked the Canon and iTunes site but couldn't find anything.

Well, I'm not really sure to be honest. All I know is that I went back to factory settings on my 30d, and then the pilot light began to come on in all of my manual settings - which it wasn't doing before of course. The flash isn't firing at all - as I said, the pilot isn't even coming on.

So, I played around, and tried to remember what settings I had my camera on, and when I went to continous shoot, the speedlight showed no pilot again at all. I went off continous shoot, and then the pilot came back on again. This happened in all the manual modes I spoke of previously. So, I don't know why but for some reason I am getting no pilot in manual settings when my camera is in continous shoot. It is working when I take it off continous.

If you are talking about the focus assist light, then yes, it will not operate in AI Servo (continuous focus). I thought you were talking about the actual flash not firing. These are two separate things.

Although the manual-focus scale shown in the app is in meaningless units (0% to 100%), I have been told that 0% focuses on things nearest to the lens and 100% is furthest away. This is not the case on my 13 Pro, however. Judging from the on-screen image (difficult since I don't see any way to magnify it when focusing), infinity focus is considerably below 100%, somewhere around 75-85%. Higher "percentages" of focus make the most distant objects (and everything else) distinctly blurred. Can somebody explain what's going on?

I finally got hold of Apple tech support on this problem. Not surprisingly, however, Apple refuses to consider any issues manifested in a third-party app. Apparently it's up to Adobe to solve "their own" problems. Apple says it will only get involved if the third-party itself comes to them for help.

my system has changed from motion to manual, this has just happened over the last couple of days. i have always had it on motion, i am not getting notifications while it is on manual. I have tried to change it but doesnt stay on motion. I need it to be on motion and get the notifications. I use the system for security purposes for our home that is in another town a 3hrs drive away.

Are the running men for each camera in the Devices tab black or gray? Gray means disarmed. If so, use the Mode tab, click on your base and make sure the Armed mode is selected. If things look good, try power cycling the base.

Maybe your cameras are no longer detecting motion. Try to remove the battery for 10 seconds then trigger motion after it. If camera is still not detecting motion that means the camera no longer have a proper rule. So you may need to remove the camera from your account by going to Settings > My Devices > select affected camera > remove device.

New DroneDeploy user for a little over a month. I am working to improve map quality/consistency and am studying manual camera settings. Flying Mavic Pro with iPad Mini 4. I have searched forum for information and have found useful tips on setting high shutter speed. low ISO, and manual white balance. I am hoping for answers to a couple of specific questions.

First, I am interested in manual focus. In addition to establishing other manual camera settings during DJI GO4 controlled test flight, I would like to set manual focus then have it hold that setting during DD mission. Many of my missions have trees/forested areas within the cleared areas that I am interested in mapping and I am concerned that they are affecting autofocus. Is manual focus a better solution and, if so, will a manual focus setting be held as are other camera settings when switching to the DD app?

Second, I would like to know more specifics about switching from the DJI Go4 app to the DD app after camera setup. Can I shut down the DJI app in mid-flight (preferably at mission altitude and near mission start point) and start the DD app and fly the mission from there or do I need to land first to re-set RTH point? If I do need to land, are there any specific procedures for switching apps. I assume it is just force closing the DJI app and then opening the DD app (or do I leave DJI app running in the background?). Are there any other specifics? Do I need to cold boot any devices (remote, drone or iPad), etc.

Finally, what is the procedure if I have a long mission and need to switch batteries? Will the camera setting be held or do I need to re-fly a test mission with DJI app to re-set everything? If I close the DD app to re-open the DJI app will my half completed mission status in DD be lost?

Also, my short mini-USB to iPhone cord integrated into the remote was junk. Replaced it with a short USB to iPhone cord and a couple other accessories from Amazon and the whole setup is light years better than original iPhone setup (see below) . If you are committed to DD and think it worthwhile to invest the capital I think its worth it.

Tested new methodology for running DD yesterday and am very happy with it. After confirming everything is set to go with DD (mission already defined, iPad rebooted for clean start, etc.) I launch with Go4 app and climb to altitude of planned DD mission. I then pan gimbal straight down while drone is hovering and tap screen to autofocus on ground (not tree tops , unless I want to map treetops). As soon as autofocus is complete, I switch to manual focus (do not refocus, it will hold the set autofocus setting). Then I force close Go4 app and and open DD app while drone is hovering. Select mission and tap fly button. After checklist runs, I push final check button. Drone will immediate head to fisr waypoint and fly mission. Focus will hold at ground setting thru whole mission. For missions that take more than one battery, I broke them up into multiple missions so that I can re-run the focus procedure before each mission; however, I think that the manual focus setting will hold without re-running the Go4 focus procedure. Another poster indicated as much and during my testing yesterday, the behavior of the drone led me to believe this is accurate. I will test further as soon as I can to confirm.
