Question about Canon 28-135mm f/3.5-5.6 EF IS USM AF Lens

1 Answer

Canon 28-135mm IS lens makes clicking noises

It seems if my Canon 50D is on for awhile, the lens will begin adjusting the f/stop. I think is what it's doing since the f/stop will flash between what I have it set to and 0.0. At one point I got an error message saying the lens contacts were dirty.  Is this a problem with the lens or the camera? Thanks

    I have the same problem...camera is almost 1 month old and I've tried cleaning the contacts multiple times. Tried different camera settings, etc. I doubt seriously if it's the mirrors on the camera as the error message states to clean the contacts. My guess is the lens itself...did you have any luck?

    i'm frustrated too. my camera/lens goes ballistic making clicking sounds and i am unable focus or take any photos. now, my 50mm 1.4 lens will quit take photos and stop autofocusing.

Check out the mirrors on the camera, This is a pretty popular problem with the canon cameras. The lens gets dirty in the camera and it sends a error code

Focus out problem in canon 50d while using 24-70mm lens?


If by a "normal" lens, you mean a 35mm or 50mm fixed focal length - often called "prime" lens, that is to be expected. The additional and internal rotating optical elements all contribute to loss of clarity, color loss, and increased chromatic aberration that starts to become noticeable when compared to use of a prime lens. It's a trade off; less number of lenses to carry and lower cost when using wide angle zoom lenses as opposed to a prime lens for even just a few of the focal lengths offered by the wide angle zoom types.

You can minimize the unwanted effects by staying away from both the extreme wide angle and zoom focal lengths as well as the widest aperture settings. If you can stay 2 or 3 stops smaller from wide open, you can limit these destractions from your pictures. This is recommended advice for nearly every lens: Keep away from the extremes.

Good luck!

I keep getting err 30 on my cannon 50d. I think I need a new shutter. How long would it take to replace it? I am going out of town Friday.


Hi, Unfortunately having a shutter replaced, when sending the camera off to Canon takes 8-12 weeks in my experience.

What does error30 mean and how can I fix it? I own a Canon 50d


This "err 30" has been quite popular with the 50D as there were several batches manufactured with problematic shutters. This is a shutter failing to open when you take a picture. Canon is aware of this and I have personally sent mine that was even 4 months past out of warranty and it was promptly taken cared of.
Anyhow, I have corrected another 50D using these steps: (Note: Your mileage may vary, I can't even believe how simple the solution was. So, It might not work for all.)
1.) Be in a clean, minimal dust environment with no fans and good lighting. 2.) Do a mirror lock-up (Press button with gray dot left of viewfinder) then turn off camera. 3.) Remove lens from camera body. If you can see the sensor (greenish rectangular flat), send your camera to a Canon Facility for a warranty repair. If not, continue to step 4. 4.) If you see that the shutter (4 lines of black thin film over-lapping each other's tips lengthwise) is closed. Turn camera on. 5.) Find "Sensor Cleaning" from on of the "Wrench" tab menu. Select "Clean Manually", follow camera instructions. i.e "Turn off after manually cleaning..." (Very important!) 6.) While camera is off, attach lens. Turn on camera. Do a mirror lock-up. You should see something on the LCD screen now. Take a picture. 7.) Snap a picture again. This time the mirror would have gone down (so you can use the viewfinder) and the shutter should have opened. The camera should then operate normally.

I love taking wedding photos. do you think the


Yes, I'm sure that camera will be fine, the 20D some years back was considered OK for wedding images
BUT its more about the quality of the LENS you are using and will it wok in all situations
I used to do a lot of Film work for weddings and used various canon camera bodies, but the lenses where the important factor for speed, composition - I also used a top quality flash unit, that could be used OFF camera. I used a 28mm lens, 50mm 1.8 lens - very high quality and cheaply available, 135mm portrait lens, and various zoom lens
I also always used a tripod, so i could compose the groups and then leave, the camera and go and work with setting up the group, and using a remote take the picture. I also used a flash frame on the flash, so I could turn the camera between portrait and landscape with out worrying about the flash gun

Brand New EAOS 50D is telling me that communication between lense and camera is not working.


Sorry to hear about your Canon EOS 50 D. problem. The first thing I would check is to be sure the contacts on the back of the lens are clean and the corresponding contacts on the camera body are also clean. You can use isopropyl rubbing alcohol and a Q-tip to clean these contacts. If this fails to make the system work we will need to test the lens features. begin by turning the autofocus and the image stabilizer both off on the lens.Set the camera two the AV mode. Adjust the F. stop to read F-22. Look at down the front of the lens barrel as you press the depth of field preview button. Every time the button is depressed you should see the diaphragm open and close inside the lens it should do this as quickly as you press the button if it fails to open and close the problem you're experiencing is probably with the diaphragm control unit.if you find the diaphragm functions properly the next step would be to engage the image stabilizer again attempt a photograph if it fails then it's probably a lens related issue and I would contact Canon directly for war to service. You may also find that if you've purchased your unit locally that your local store or if it's been within a two-week period may exchange a product for you I would be happy to answer any further questions you might have feel free to contact me directly@Daveadvancecamera.com

Autofocus on 300mm 2.8 IS not working with 50D


Make sure the AF/MF mode button on the lens is set to AF.
What focusing mode do you have selected in the camera? Single Shot, AI focus or AI Servo? 
If Custom Function "C.Fn IV -1 Shutter button/AF-ON button" is set to option 2 or 3, the AF will start when you press the AF-ON button.
I hope this help you!
