I find the collar with this lens highly ineffective and obtrusive. Any suggestions to circumvent the problem.

I bought this lens because of the collar, focal length, and optical sharpness. The collar allows one to easily switch from horizontal to vertical format without having to remove the camera from the tripod. You could probably have the collar removed by a competent repair shop. To each their own!!!!

As you probably know, it is very simple to remove the lens collar - you just loosen the knob on the collar, then pull the knob out to disengage the collar from the lens (Caution! make sure you have a good hold on the lens separately, or the camera and lens secured by a strap around your neck, before you remove the collar). You can use this lens hand-held for most non-macro shots since the OS feature stabilizes the lens quite well. Or you can use the lens for macro shots, but a flash unit such as ring flash or special tandem two-flash units designed for macro shots might be better. As you also probably know, the OS feature does not help much for macro work. Or you can leave the lens collar on the lens, attach the appropriate Arca-Swiss or other adapter if needed, then use a good tripod (or monopod) and ball head for macro shots without flash. Good luck with the lens - I have found mine to be quite sharp and excellent for both macro and, e.g., portrait work.

The collar is designed for easy removal-just twist the knurled knob to loosen and then pull up on the knob and the collar can then be detached. I see from your comment to a previous response that your issue is with the knob itself when the knob is in the vertical position. I don't believe you can remove the knob and still have the collar attached so for your situation it appears you will need to remove the collar when shooting vertically.

You have to get very close to the subject. I'm talking like less than an inch away. It took me a couple of tries to figure it out. It may help if you take your case off so that the lens is directly on top of the camera lens.

I also had trouble at first. There is a metal tab on the interior of the adapter that you have to push in to get it to "lock." You may need to use a small screwdriver to hold it down while placing it onto the lens. Once it's on you'll know.

The problem is the ring interferes with the lens barrel when it's fully retracted. Zoom it out, attach the ring, then when it retracts it will not quite go in as far but will still work. I hope this helps you out altho I dont know if there is much of a loss in focal length, decide for yourself.

I did not have success with the collar, so I discarded it and used Feliway aerosol and plug-in diffusers. I did find success with the Feliway products. Perhaps you have the collar/s on too tight which may be affecting the skin. Hope my experience was helpful.

I had my ELPH for two weeks and the lens cover stopped opening all the way up. I have to use my finger to push the lens cover all the way open. Sometimes it doesn't close all the either. I'd take a refund or exchange if I knew how to go about it.

Their is a thread mount ring that fits onto the thread of the lens and the hood twists onto the mount ring. The mount ring stay's in place, while you twist the hood off flip it over and twist it back onto the mount ring. Just reverse the process to flip it back. Hope this been some help.

I haven't gotten mine yet, but I ordered it. I think I read that the silver ring on the front of the lense is how you adjust the focus...give it a try! If it doesn't work, contact the seller or something.

Theres a ring that comes off. Its been a while since ive used mine but you may need to screw on ring to lens first then add the lens adapter. Or try with out the ring? Also it only fitd on my kit lens. Check thread size

I don't have a lens as wide as 16 mm , much less a 16. I would suggest trying the lens shade out. Maybe the vendor will allow you to try it out with an option to return it, if it doesn't work.

I ordered a collar on ebay....works great on the slider....but it is a little awkward. The lens just slides smoothly back and forth on the tripod while it is attached to the camera.Works good for me...don't tighten the collar too tight as it effects the rubber coating around the slider....you can do it.

There's a little tab that locks the adapter onto the lens. You can see it engaging if you look while connecting the adapter to the lens. The first time I tried to connect, I bent the tab trying to force the adapter and the lens wouldn't lock. I had to bend the tab upward with pliers so it would engage the lens. It was all good news from there.

Screw in center needs to be tight...no wobbly...and the rotation quit on mine after a short time (couple weeks of 24/7)...a little light lube might get it going again...I suggest 3-in-one oil...sewing machine oil...don't get it on the lens or it will crap it out...I used P-B Blaster and it wasted my lens...but it quit spinning again very shortly ,so that was a moot point...hthy...Hobbiehubbcapp.

I second guessed myself as well in the beginning. The lens has a pretty long manual throw. i.e. it takes some big turns to get things into focus manually. Keep trying and it should eventually get things into focus.

I have not had this problem. I would suggest some cleaner. Perhaps the manufacturer can make a recommendation based on the exact materials used to make the lenses.

Make sure you're trying to turn the collar only... its right hand thread so turn counter clockwise as you're looking at the tip head on... try wrapping a rag around the collar and use a channel lock style pliers

I'm having the same problem using this lens on my D80 camera. What you are saying is that there is no way for me to use the ring to adjust the aperture? It only works when locked on 22?? This doesn't seem right.
