I have a broken stabilier on/off switch on a 400 telephoto canon lens. Is there a schematic I can view to show how to place the circuit wire?

The best way to get it done right after you drop the lense is send it to NIKON NY . They put the lense on a resolution bench test and it make sure the resolution is great ,. This lense is very criticial and it is a must or your wasting your money . The reason is this ., The lense is a wide angle and sometimes photographers have probelms with 17-55mm lenses and sub mirror problems . So its best to be safe than sorry .

Get the Canon EF 70-300mm IS USM about $500 and EFS 17-85mm IS USM about $300. The 75-300 all of them I would not use them 4 a body cap. Camera is fine or step up to XSI.

Did you tell the camera that you are using an external/additional lens? You have to specify it somewhere in the menu, the camera gives you some options (the lens model numbers) and you need to match it with your lens' model number.

Yes...the Canon brand is made to work properly with the camera.

Hello

The problem is that the lens has become stuck in the barrel. There are some DIY solutions you could try, but the probability is that you will have to get it fixed by a professional.

Use these at own risk as it may further damage the camera.

Firstly , try connecting your ac adapter or usb cable.

Try holding the shutter button while switching on the camera.

Look at the lens , and if some of the lens 'circles' is misaligned or not concentric then try wiggling it (while holding camera lens down).

Try gently pushing or pulling the lens when it extends but this is risky as it may cause the lens barrel to slip out of its guidance system.

Another way to do this is to place the camera lens down on a hard surface and then power it up. Be sure to use a soft cloth or something similar as to not scratch your lens or casing. Let the lens push the camera up and down a few times and sometimes the little resistance provided by the camera is enough to get things going again.

Try hitting your camera near the lens on the body with the soft tissue on the palm of your hand.

Other than that , I would take the camera to a repair center for a evaluation to see if it would cost more to repair than to replace the camera.

If it is still under warranty I would suggest you take it in before trying any of these steps and remove any off-brand batteries or accessories as some stores are really fussy about warranty repairs on camera's with non-brand accessories.

Hope the advise is useful.
