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!

SOURCE: I have a Canon EF 300mm f/2.8L USM Lens

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.

SOURCE: Water inside the lens (Canon EF-S 17-85mm F4.5-f5.6 lens)

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.

Very loose lens 75-300mm canon zoom


If it is loose on the camera mount, try to avoid using it. If it causes your camera mount to distort, then you won't have much luck with any other lenses!
If it is "loose" meaning: it rattles and there's a bit of play in the 'barrel'...yuuup - get used to it. She's an oldie but a goodie.

My lens is really loose when I zoom out , how can I fix it, I have a canon ef 75mm to 300mm


There's a screw located on the barrel of the lens. This may help tighten things up, but don't count on it. Don't try to take it apart unless you know what you're doing. There are a series of sleaves within the barrel which need to match up and you might have to fork out more than the lens is worth just to get it fixed

Does my Sigma 28-105 mm Aspherical for film camera work on my Canon 5D Mark III?


If the Sigma lens mount is a Canon FD fitting then you can get an adapter FD to EF that will allow you to use the old lens in manual mode. If your camera isn't designed to take EF-s lenses then they will not fit on the camera. My EF-s lenses will not fit on my 6D.

Canon 17-85 IS zoom ring locked at 17mm.


Sometimes, if that lens has heavy use or if it has been traveled with a lot, several of the internal zoom screws may come loose deep inside the lens and cause the zoom to freeze. It requires a complete disassembly of the lens to reach the screws and re-seal them so it does not happen again.

Best telephot zoom lense for my canon 1000d


That's a decision only you can make. What's most important to you? Long focal length? Wide zoom range? Lens speed (maximum aperture)? Weight? Cost?

Also, what do you want to do with the lens? The best zoom lens for taking wedding pictures is not necessarily the best zoom lens for taking sports pictures.

Canon EF 75-300mm f/4-5.6 Repair Manual


Mine had the same problem. The electric flexible wire that links to the moving aperture motor in the center is most likely broken, causing the aperture to stop reopen after a shot. this could be proved if you feel something touching inside when zoom. (that is caused by the loose flexible wire, if so do not zoom anymore, you could further damage the wire) It need to be replaced and this requires the complete disassmebly of the lens. I repaired mine myself by adding a thin wire, took me more than 10 hours in total (first tear it apert, pin point the problem, then think of a solution because I did not have the parts for repair, then finally repaired it). If you have never done lens/electronic repair before, don't do that, too many tricks that could lead to further damage.
