Question about Canon EF 70-300mm f/4.5-5.6 DOIS USM Lens
Hello- And Thanks for your help in advance. I dropped my camera bag and after the drop, I noticed the end of my lens had broke. It split where the filter threads into the lens end. The part that broke was right along the threads themselves. Looking at the lens, I see three small screws which seem to be connected below to the part that broke so I was assuming this piece could be replaced. I can send photos of the lens if needed. I guess I'm looking for that replacement part and a price if possible.
Here is everything I see on the lens:Canon Zoom Lens EF 75-300mm 1:4-5.6 III USM Ultrasonic 1.5m/4.9ft

Hello Pittsburgh! I lived there for 3 years! Dreadful city. :-)
Now, your lens must have a problem with the guide rails/pins. If you dropped it or bumped it, you might have broken/damaged those guide rails. Another reason might be sand/grit in the zoom mechanism.
You may try stripping the lens slowly and see if you can identify the problem. Most lenses are easy to disassemble, you start from the rear mount area, take off screws, and parts one by one, and be organized (i.e., take photos for every step and don't mix the screws).

Lens errors are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended ...
Here's some things that you can do to try to correct it. They only seem to work for less than 50% of the lens errors, but if the camera is out of warranty, they're worth a try:

If it is still under warranty , please repair it.
If it is out of warranty. Try to get a quote, it the quote is more than 50% of original value , forget it.
For digital camera's they die like flies. New ones are better and cheaper anyway.

You have to disassembly your camera for it, including the lens assembly.
Even if you have experience and skills in fixing electronic devices, I don't recommend it, since any particle of dust will get inside the lens and your camera, and will affect it.
The recommended place to perfom such cleaning activity is a Clean room (class 3 or higher), and have handy the proper cleaning tools.
Disassembling the lens is tricky and also needs a lot of patience and technique skills to do it properly.
Imagine that by accident a spring pops up a tiny metal ball (1.5 mm diameter) and you lose it in your home, then because of it, your lens will not work properly.
If it has warranty, I do recommend you to send it to cleainig to a professional repair and cleaning service.
If still you have questions or doubts, or need a cheaper quote for it (after get some quotes from local repair centers for comparison), you can contact the ebay seller Great_items_2004

Testimonial: "THANK YOU"
That was a very sad thing to happen. There is no quick fix solution for this. You should take it to an authorized service center. But I fear this is not going to be an inexpensive process. Let them have a look and assess the damages. We have no way of judging what could have happened inside--whether there has been any misalignment of elements or focusing mechanism.
