Question about Canon 75-300mm f/4-5.6 III USM EF Lens
I bought a used Canon EF 75-300mm III Zoom Lens,but the len is very loose, is that problem
Long and short of it...if the photos are close to "decent", dont worry bout it :) It aint no L Lens but can still throw out a good pic every now n then. Tip it from one end to the other whilst holding it...if you hear something go \'ring-a-chicka-chink-chink-clunk\', then youve got problems, otherwise grin and bear the looseness - mine lasted 6 years of hard yacker before i dropped it in the drink!

Here is a link to many Canon products in PDF form: Canon Parts Lists
Unfortunately, the only 300mm 2.8 lens listed is the IS version
The procedure is not that complicated, but you need to pay attention to the connections on the circuit board. The mount is removed, and you need to remove the small screws that hold the connector board to the mount ring first.
I cannot do live chat due to I use a Mac, but I will monitor the thread if you have questions,

The zoom creep is an easy fix for Canon. I really do not recommend trying to tighten it yourself, since that would void your warranty.
It is usually free to tighten the zoom ring.

if it is only fogged you can blow hot air on the lens while fully zoomed in and after the water has evaporated, zoom out to compress the moist air out. do this several times.
