Nikon can i remove the glass lense from this cameraa

hope this you tube link helps Nikon coolpix battery charging problem

I would get a new camera. A new lens with installation will cost far more then the camera is worth.

hello,you have the most popular problem,that every 1 meets,regarding most modern consumer good's,relating with battery's. DO NOT charge up your battery,too often,as you unwittingly are OVERCHARGING the battery,as temperature is directly related to cells that are taking in far too much current,use your camera,till it dies(total loss of power) then only charge for a brief period,then leave camera for a while,before re-using. vary the state of charge/in relationship to usage,and do only charge battery infrequently. hope that helps, cheers.

The Nikon L810 does not have interchangeable lenses. You can buy accessory lenses to fit on the front of the camera's built-in lens, but you cannot remove the lens itself.

Sorry, you can't. The Tair 300mm uses the M42 mount, while Nikon SLRs (film and digital) use the Nikon F mount. Due to the deeper flange distance of the Nikon mount, M42 lenses cannot be adapted to Nikon cameras without losing infinity focus.

Holy Smokes, well if I were you right now I'd put it back together and send it to Sigma for repair cause you dismantle a lens like that there is no way you are going to align those lens elements without the proper equipment.

Using anything more then lens cleaner for camera optics will in fact remove the coating from the lens.

What you have isn't like the lenses from a "View" camera where it was possible to remove one lens group and replace with another but, those lenses were made and used 70 years ago.

Lens technology has changed a bit since then.

I had a manual focus Nikon F2.8 lens one time that had a coating separation on the front element that caused some wicked flare. I took eye glass cleaner and Windex to it to remove the rest of the coating so I could continue the shoot. I then sent the lens to Nikon for repair.

Best of luck with that one

Hi, there.
I assume you mean the 77mm FILTER that was screwed on the lens.

First you need to tell me where you got a nikkor 28-135 - I dont find any reference to that piece of glass on the nikon site - I believe you might have a sigma or some other brand glass but not NIKKOR... TO your problem - have you tried setting the f-stop to f22? Most lenses talk to the camera bodies via f22 - if not try opening the lens up to its widest setting - typically when you see an F flashing it is because the f stops have been moved off of the AUTOMATIC SETTING - have you tried using the camera in manual mode?

Mirror lenses have no aperture nor AF, so they mount via a T mount. A $30 item that screws on the end of a mirror lens that fits your camera. A mirror lens has it's physical likes and dislikes against a glass 500mm. A glass 500mm will give a better image if you can stop down to F8 F16. Then you have shutter speeds to consider and those lenses are usually connected to the camera's contacts. So they can be specific to a single body. There are older Tamron lenses that take Adaptall mounts, they are old and hard to find. But they solved the multiple body problems for "auto" program lenses. None had AF, when AF camera around, we were back to individual lenses per body.

D-SLR cameras are designed to be used with interchangeable lenses and foreign matter may enter the camera when lenses are changed. Once inside the camera, this foreign matter may adhere to the sensor, where it may appear in photographs taken under certain conditions. To prevent foreign matter from entering the camera

• do not change lenses in dusty environments
• point the camera down when changing lenses.
• 
  

To protect the camera when no lens is in place be sure to thread on the body cap provided with the camera, being careful to first remove all dust and other foreign matter that may be adhering to the body cap.
Remove foreign matter from low-pass filter

1. Clean the low-pass filter covering the sensor as instructed in the camera manual or continue reading below.
2. Have the low-pass filter cleaned by authorized Nikon Authorized Service Center
3. The Nikon D300 and D60 has the ability to clean the sensor* using the "Clean Image Sensor" feature. Please see page 371 in your D300 User's Manual, and page160 in your D60 User's Manual for more information. *Clean Image Sensor may not remove all sensor contamination and additional manual cleaning may be necessary. See page 374 in the D300 manual, and page 162 in the D60 manual for more information.
4. Fix images with black spots
   Photographs with dust or foreign matter on the low-pass filter can be retouched using the 'Image Dust Off' function available in Nikon Capture 4 or later (available separately) if the image was taken in the NEF format, for more information visit the article on 'How does Image Dust off' work.
