How to clean and lubricate tamron sp 300mm f2.8 LD (IF) manual focus.
You mean the shutter of your camera isn't moving?
It shouldn't really need lubricate... as far as cleaning ... just luke warm soapy water. do NOT use alcohol or such on the lens as that will destroy the coating on the lense

Hi, I've a Sigma 28-105mm aspherical 3.5-5.6 lens. Auto focus does not engage. I can hear the motor trying, but the ring does not turn. When I switch to manual focus, I can turn the ring to focus manually, but I still hear the motor trying to use autofocus. Additionally, sometimes the shutter will not fire in manual focus while the motor is still searching. I've cleaned the contacts, but no joy. I suspect a faulty switch, but that doesn't completely explain the autofocus not engaging. I am
Well, I think you have at least one problem pinpointed, in that I suspect the focusing ring is jammed, and cannot rotate with the electromagnet signals. The other problem might be a faulty auto/manual switch. Of course, check for oxidation and e ... Digital Cameras
Focusing problem Until recently, I was able to look through the view finder and auto focus my image. Now, camera will not show me subject in focus, but after a I make a shot, image is in focus in the preview. Manual focus works just fine, it's the auto focus I am concerned about. I have cleaned the lens - please help!
Well, stupid me, I didn't realize there is a diopter adjustment button directly to the right of the viewfinder. I would NEVER have known it was there, but after asking my photo-nerd friends all of a sudden the solution was apparent. Still a wasted da ... Nikon D50 Digital Camera
I have a canon rebel xsi that is not taking pictures on auto focus. It will take pictures on manual focus, but they're blurry. I changed my lens to a bigger one to see if it was the lens or camera, and it's the camera. I had the same problem with the other lens. I've tried cleaning it & turning the lens focus ring but is still doing it. Anyone know how to fix this problem?

Focus I have had my camera for a year now and loved it but for some reason it will not focus anymore. I have went through the manual and tried everything it has to offer. I recharged my batteries and it still doesn't work. I cleaned my lens and I toggled the focus and still nothing. It all comes up very fuzzy. Help! I don't want to buy a new camera!

I recently went on a trip to Hawaii, wanting the best pictures possible, I cleaned my Rebel XT and when I got to Hawaii it would focus in and out but would not lock in focus so as to shot the picture. I also noticed the autofocus points do not light up and I can not manually focus either. Is this repairable?

Canon EOS Rebel XT with EFS 18-55mm lens. Trouble-free for two years. During a weekend of lots of use, suddenly the camera would not autofocus. Switching to manual focus, the camera worked. Then it started working okay in autofocus. Later that day quit altogether. (Would not release shutter even in manual mode.) Removed the lens and cleaned the contacts on both lens and camera, started working okay but only temporary. Went through several cycles of this over the weekend, so I'm not sure

On the Canon G3 I have issues with the main dial on the handgrip (used for aperture shutter speed and manual focus) while in Manual mode. it will change settings only some of the time! is this usually due to dust in the area and can it be cleaned or otherwise made operational?
Thanx for nothing if and when I fix the problem with the G3 I will likely not tell you so that you can charge $9.99 to the next person to ask the same question. This is the kind of scam that I expected and the likelyhood of hearing back f ... Digital Cameras
Good Morning I went hiking in broad daylight this past weekend and the autofocus would not work. I have a Canon 40D with a TAmron 18-270. I used av, tv, p, m and auto and I could not autofocus the camera. All I could do is to switch to manual focus to get it to work. When the lens was set to AF all you could is hear is it racking back and forth tying to focus. VERY FRUSTRATING.. Any ideas of what it may be or a setting I might have set accidentally. Any help is appreciated. Bob

Nikon d40 18-55mm lens will not auto focus. Switch on lens is on autofocus not manual and shutter button will not depress. Worked over the summer and our 55-200mm lens works fine so it's definitely not the camera. Any repair suggestions? Tried cleaning and still does not autofocus.

Focus Problem Dear folks, I just bought a (new) Canon A75, and it doesn't seem to focus. At all. Even on manual focus, not only can I not get it to focus properly, the focus doesn't change at all. When on AF, it doesn't beep like the manual says it should, and the yellow light blinks, as it's supposed to when there's a focus issue. The focus assist light is working. Can anybody think of anything I should try? The manual is of no help. This is my first digital camera, so I'm not ruling out the po

Focus There is one problem that I have with this camera - Auto Focus in low lighting and it has really limited manual focus. Outdoors this camera is outstanding, I haven't found any pitfalls outdoors yet. 10x optical zoom plus 2.5" LCD WOW. Although the LCD is littly choppy, but I don't care about that, pictures turn out really gooood. Anyways back to Auto Focus problem. Do any of you have the same problem? Or this is my ability problem? That limited manual focus really bugs me! I'd like to hear

I have a new k20D I have had it less than a week and I can't seem to get the auto focus to work. I can manually focus but when on auto I get the red square for a second and then it goes off it does not move the lens into focus and it does not beep. I am wondering if I have a setting wrong but I reviewed the manual and I don't think I am missing something but maybe I am.
Does your lens have a ring on it with various lens openings marked on it such as 3.5, 22 etc.? If so, it should also have a "A" setting which is where you should have it. Also, I'm assuming your lens is an auto-focus lens. ... Pentax K20D Digital Camera

When I change my focus from manual to automatic the camera doesn't take pictures. It will attempt to focus but then it will focus and it will be blurry and it won't take the picture, then it repeats. But the manual setting works fine :/
Auto mode is the point-and-shoot mode. It is not the camera problem. It is a common problem amongst nikkor kit lenses. Get your lens checked to the dealer, or any Nikon customer care. If its under warranty, it'll be replaced. ... Nikon D3000 Digital Camera
I was taking pictures into bright sunlight switching between manual and automatic settings, and manual and automatic focus. First, the picutre would take, but the shutter would not open (viewfinder would remain closed) switching from manual to automatic focus fixed this issue. However now it seems that the aperture is stuck, and not enough light gets through to the viewfinder. How can I fix this?

I have a Canon Digital Rebel XT camera using a 75-300mm telephoto lens. My problem with the lens is that at times it is hard to adjust the focus either manually or automatically with the camera. I hear something rattling around inside the lens and at times the lens will not auto-focus and I have to remove the lens and manually twist it to get it back to some normal operation. Is this fixable or do I need a new lens?
