What does Tamron have to say about the issue of the faulty zoom ring??

I don't know, sorry. I just returned the faulty unit to Amazon and received a refund. I then purchased the non VC Tamron 17-50 lens which has worked fine.

Went on a trip with my new D50 and it stopped working after 5-6 pictures. Showed an error message. When I got back home I decided to read the book. Seems the lens slipped out of F22 to F16. Rotating the F-ring back to F22 fixed the problem. Ignorant me. Since then I try to only purchase lenses with a little snaplock on the f-ring. Problem solved.

I bought two of these, and at first they worked well. Then abruptly one of them stopped triggering, even though the screen came on, and it synced to the camera, because when I changed the camera settings, I could hear the attached flash changing its zoom setting. I tried all combinations of channels and groups, with no success. I am very, very disappointed in this product. I cannot find any way to contact the manufacturer for help. Good luck.

I don't have this camera, but I recently returned Samsung WB380 camera reluctantly due to the exact same problem. The zoom lever became "sticky" in about a week meaning it never returns to the middle position. Camera thinks you are still trying to zoom and doesn't let you take a picture until you manually push the zoom lever to the center position.Otherwise, the camera was fantastic.

I ordered Tamron 1.4x for my Nikon. I have not had any problems with the Teleconverter. But realize that I made sure it was for a Nikon not Canon.

Mine is perfectrly 'tightened', focus ring fits perfectly and it runs so smooth! Only 'problem' that I notice is the 'noise' during IS activation. But, it turned out that Hybrid IS is such noisy. If there are problems, maybe you should thing about returnig product?

Hi Frank, I purchased this scope about 6 months ago and have had great luck with it. I dont care for the red and green back lights and shoot it with no lighting. As far as it changing when zooming mine doesn't do that. I would say you might have received a defective one since the reticle is separate from the lens and sounds as if it might be moving slightly when you zoom. Amazon is great about replacing items, shoot them an email.

Same trouble I had with mine right out of the box... requires Canon service and likely replacement. The electronic lenses are very flimsy and the slightest bit of dirt will ruin them.

Hi bruno, I mentioned a rather stiff zoom ring starting around 100mm and no it didn't get better. I did exchange it and the new copy was better but still a bit stiff, the low light characteristics on the replacement improved just a little bit . This lens for me pretty much spends it's time in a drawer unless I'm going somewhere outside that requires going light and the photo's taken aren't important. It's rarely on my camera.

One issue: sometimes it loose part of the conection and loose the Aperture control. You need to reconect an its ok. The same thing with metabones, so I recomend it.

There is new information on the page that I linked to in my previous comment. It looks like Canon now knows which lenses are affected, and they offer free repairs - starting on 7/18. From what they write, it also sounds like newer lenses do no longer have this problem.

It's worth a try, because the machine tries to load the firmware at startup. If the firmware has become corrupted, then it would make sense that the display could have issues. I suggest trying it, along with following the steps that are outlined in the manual for firmware update. You might have to follow them blindly, but it's not hard.

I am not sure - but the zoom did not work when I received it and I returned it...

Ming Thein never mentions a problem. http://blog.mingthein.com/2013/06/14/lens-review-panasonic-14-42-3-5-5-6-x-g/

This is a common problem with this model, and a design fault to which Canon will not admit. Even if your warranty has long expired, you can get a replacement camera or repair because this camera was 'not of merchantable quality.' I am thinking of mounting a group legal action to make this happen. If you have this problem with this model, drop me an email thewideangleco[at]gmail.com. Don't send any personal details, just a note to say that you have this camera, or had it, with the fault of it not focussing when zoomed. When the legal action is prepared, I will contact you with details. This will cost you nothing at all. This is a common problem with this model, and a design fault to which Canon will not admit.

I as well have a focus problem, I have to bump the zoom a bit when I first start the camera. Not aware of any solutions and am looking for a warranty fix.
