The way every grip I've ever used has worked is that whatever particular button on the grip corresponds to a particular button on the camera will function the same way as that button on the camera body without any additional setup. Just as pressing the shutter release on the grip does the exact same thing as pressing the shutter button on the camera, if the ...

It sound like you may have damaged one of the points, since you say the 50 no goes on without a problem and your other lense feel loose. Check all the points and see if you have damaged the connecting ring on the camera, if these are damaged then no resetting will work you will have to focus manually from now on, to get them fixed is way to expensive it ...

If you think the motor is only working in one direction, you might try to test the theory by focusing in live mode. If it's like mine, it will usually go back and forth to home in on the sharpest focus (using contrast rather than phase detection), so if the motor is only working in one direction it will probably not be able to focus in live mode. Of ...

The hack itself will always work, but the reliability of the autofocus suffers. The lens you're asking about is a f/6,3 in the long end and with a 2x teleconverter the autofocus will probably be painfully bad if working at all. I've used the sigma 1.4x teleconverter (connectors masked) on the same lens and even that struggles autofocusing on bodies that are ...

The answer to the question should be no for G-series Nikon lenses. The focus ring mechanism is designed to disengage from the lens when it reaches the limit on either end, allowing the ring to continue spinning freely. You usually feel a bit of resistance at those points. Looking at the question though, it looks like it is not a problem with the lens but ...

Are you sure you set focus back to auto on both the body and the lens? I've made this exact mistake and thought I broke something and it was just me forgetting to turn auto back on. Good luck.

First off, select an AF mode other than Zone AF. In my experience, as well as that of many others', it just doesn't work well when shooting action with the 7D. The camera will likely focus on something, but it probably won't be what you wanted to be in focus. Try either Single-point AF or AF point expansion. Set up your camera so that nudging the little ...

Try cleaning the contacts on the lens mount and checking them for damage, it could be that the camera can't communicate with the lens. I have a Tamron 18-270 PZD which stops autofocusing occasionally, I have to wiggle the focus ring for it to start moving.

Try giving the focus ring a little nudge when the autofocus gets stuck. I have a Tamron 18-270 which has the same issue when zoomed at 150mm or more. It seems that due to the small change in focus required, the camera does not power the motor enough to get it moving, resulting in the noises. I don't know if you have this exact issue, it could be that the ...

(Good, thorough answers here already, but I'd like to add a shorter, simplified one...) A camera body with autofocus capability is not magically able to autofocus with any lens that can be mounted. The only lenses that can be autofocused are lenses that have been specifically designed for autofocus.

No. Modern autofocus lenses require motor in lens, older were motorized from body but were marked as AF capable. If lens is non AF it cannot use AF.

No — an autofocus motor in the body will not make older, manual focus lenses into autofocus lenses. Any autofocus lens needs a motor — it's what does the "auto", after all. (Just like an automobile would be just a ... moble without one.) There are two primary places where this motor can be placed — either in the lens itself, or in the camera body. Each of ...

To be clear, the older Nikon lenses, which are no longer manufactured but are widely available on the second hand market, were manual focus lenses. That is, they did not have any kind of autofocus capability regardless of what camera body you use them on. If you get a Nikon camera body with a built in autofocus motor, you will still be able to use these old ...

Actually, it's kind of the opposite. You need a lens with autofocusing capabilities--you just don't need one with a focus motor. That is, you'd still need AF lenses, they just don't have to be AF-S or AF-I lenses. AI lenses, for example, were designed before Nikon added autofocus to its cameras and lenses, and can only be manually focused, regardless of ...

Go into the menu system and look at the fourth page from the left. You should see AF mode, second option down. Select this and you will see three options, Live mode, :-) Live mode and Quick mode. Chances are your camera is set to :-) Live mode which is the face detection mode, select one of the other two modes and your boxes should disappear.

It sounds like you have AI Servo selected for the AF mode. The behavior you describe is normal if that is the case. To do what you want, you need to select One Shot as the AF Mode. Please note that when shooting in one of the continuous drive (burst) modes, the camera will not refocus between each shot that is taken while you continue to hold the shutter ...

There are many settings on the Canon 5D mark III that affect what you see and when you see it in the viewfinder. The camera does have the ability to indicate when focus is achieved over a certain point during manual focus, but only if all of the correct settings that affect the display are selected. Start in the menu with AF tab 3 USM lens electronic MF ...

There are two ways I see to describe what you are asking for. One would be to simply turn on all focus points in the AF Menu, manually focus, then press on half-way on the shutter release and any points that overlap the focus points and are in focus will light up. This is the same as the 7D. What I think you are ultimately looking for is commonly referred ...
