I have a Sigma 75-300 mm zoom lens. I put it into a new camera bag and it got ruined. I think that some of the material in the bag out-gassed and partially dissolved the plastic of the lens barrel. Anyway, what should be hard plastic is kinda sticky and the lens is stuck so that you can’t zoom it. Right now it is just a 75 mm lens.

My questions:

Can this be fixed?

If so, would it be worth the cost?

I suggest contacting the bag manufacturer to see if this is recurring problem with their bags. Ask, since their product ruined your lens, what will they do to correct the issue?
Worth a try. Good luck.

If so, where would be a good place to have it done?

I would appreciate any suggestions.

This is my opinion concerning these two cameras after owning them.

The image quality is better on the SX50 than the SX60. They probably should have stayed with the 12MP sensor instead of jumping to the 16MP sensor.

The SX60 has a much better electronic viewfinder, more telephoto, wider wide angle, improved auto focus, and improved video features. I like the way the SX60 handles and feels in my hands but the SX50 wins on image quality. I keep hoping that there will be a firmware fix for the IQ on the SX60.

When images are viewed at 100%, the SX50 images look cleaner. The images from the SX60 (especially at the high end of the zoom) look like there is a lot of digital interpolation- could be image compression or perhaps digital zoom combined with the optical zoom. I say this because of the strange patterns that I see in the raw files. Over 95% of the time, I shoot in the raw format so I should not have any of the digital zoom artifacts present. The full optical zoom of the SX60 has image artifacts that look similar to the image artifacts on the SX50 using the 2x teleconverter.

I think the SX50 is a much better camera for the money that the SX60.
