UV Filter damage limitation on 16-35II

[Haydn1971]

So there I was, walking along with my 6D & 16-35mm II and boom, my knee gave way on some steps, I fell to my knees and the front of the lens hit the ground, sound of glass smashing as I commando rolled over... I've grazed both my knees, my left arm and dented my pride... Plus did the attached damage to my 16-35mm II - can't get the filter off at the moment, going to take it into the local independent shop when I get home from holiday, filter is a dead loss, lens looks ok bar the marks on the outer edge and until I get the filter ring detached, I've no idea of the damage to the front filter thread. Lens appears to work, two scuffs on my 6D are annoying too :-/

So folks - always fit a filter !!!

Bummer... and people complain about filters. Easy to sigh and move on when it's not the front element. I use filters because I never use lens caps and could care less if they get scratched or damaged.

I've had this happen too, demolished a 10-Stop. A good pair of tin snips or a rock steady hand with a dremel will take that off quickly. Cut out a piece of cardboard to protect the lens front, then go at the filter ring. Nip just the outer edge, it's soft metal and it should work off pretty easily. I'd make the point of attack the dent itself. Pull that retainer clip on the inside out first though.

Scuffing the camera body is a sign of everyday use... they are meant to be used and somewhat abused, it means you out taking pictures not here on CR forum too much

Nice Flickr profile BTW!

Having the filter on may actually have caused more damage, as the lens element is recessed.

Internal focusing... that's the way they look.

I doubt that it caused more damage, but I doubt that it caused less either. Replacing the front lens element is not always a big expense, depending on the lens, however, the front barrel as well as internal components are likely damaged as well as elements internally needing to be replaced or recentered, which only a Canon authorized repair facility can do properly. A local Camera shop does not have the tools or software to re-align the lens elements.

The alignment issue is def a concern... the front elements are not a major deal breaker (usually) but if it saves you from having to send in for a scratch or minor issue. I'll let B+W take the hit.

A lens hood would help a lot in this specific case.

Dear friend, Mr. Haydn1971.
Welcome to the Club, Senior citizen club, We are not young any more, Our knees are not strong as 40 years ago , when we were young and strong as the young horse.
Yes, Last year it happened to me too, No, Not my old age, But my eyes following the most beautiful movie star, and I forget to see the big hole infront of me----Ha, Ha, Ha, But Both my Camera and Lens survive my Stupid mistake.
Have a great day, Sir.

Probably not in this case, but unless a sharp object gets in, a filter probably wouldn't offer any additional protection from a fall and the smashing glass of the filter could scratch the lens element, not to mention damage to the filter thread. Damage to the barrel and internal components would be the same with or without a filter. I just hate to see people relying on filters to offer protection on recessed elements, especially when a hood would offer just as much protection as tron mentioned. Anyway, hopefully no internal damage occurred (and hopefully this dodgy connection will let me post ).

Cheers guys, especially the Flickr one !

The 16-35mm is the only lens I don't use a good on to be fair, because it's so cumbersome in my particular bag - I don't use the lens much but thankful I'd changed from my 24-70mm 2.8 II about 3 minutes before !

It's the thread that concerned me first, but now with some time to consider, also the possibility of damage or misalignment comes to mind - I'll see what the weekend brings when I return from holiday and make a judgement on making an insurance claim - I've full specific gear insurance.

Hoods offer no protection whatsoever when you drop the lens when you are changing and you haven't put the hood on yet.

I dropped my 16-35mm about a year ago. Changing lenses, dropped it from about chest high on the concrete road I was standing on. No broken glass, but beat up the casing very bad and when you would MF it would stick. I didn't have a filter or a lens cap on. I would have had to buy a new filter, good thing I had taken it off. A UPS package and about $300 and CPS fixed it up good as new.

"Hoods offer no protection whatsoever when you drop the lens when you are changing and you haven't put the hood on yet."



I beg to differ. On two occasions I have dropped unattached lenses out of poorly fastened backpacks with the hoods reversed and they absorbed most, if not all, of the shock and neither lens was damaged. So I'd never say don't use a filter but I will say use the darn hood they gave you FREE! (L lenses anyway).

My hoods are all pretty beat but my lenses look (almost) brand new. If I didn't use hoods, my lenses would look pretty rough. It just makes sense.

I have even dropped bodies with lenses (and hoods) attached and have never damaged glass. I've broken internal stuff but am positive a filter won't save internals from shock.

Have you considered a filter wrench? I have a 24-105 that "ejected" itself out of my camera bag when I removed it from my trunk in a parking lot once because someone had forgotten to zip the bag and it landed on the front corner of the filter. There was a B+W filter on and it and the lens filter threads dented slightly, but no broken glass. I was unable to remove the filter and found a cheap filter wrench set on B&H. It was pretty wobbly and took some getting used to but I was able to remove it and now filters can thread on and off the lens with slight friction.

Never dropped a lens while changing it. I'll take the risk. I don't use filters but do religiously use lens shades. Bashed quite a few lenses around and the lens shades always saved the day. By there's no need to argue, we do what we feel is best...

Lift and remove the rubber ring on the focus ring, remove the tape.

Rotate the focus ring, you will see through the hole on the ring that there are 3 small screws that are not holding a white washer. Remove those 3 screws.

Gently pull the front filter ring part, it will pop up, along with the plastic name tag on the front element.

Now you can use a pair of pliers to bend the filter inward from a point to make it a heart shape. Then it can be removed easily. DO NOT SCREW the filter out, it will damage the filter mount on the lens.

Follow reverse step to put the filter mount back onto lens.

You may not agree, but if you have the hood reversed you have put the hood on the lens.

You are correct about the lenses protecting reversed.

I try and leave the hoods reversed on my lenses and most it is no problem, but the 16-35mm is a special case sometimes. Storage may be at a premium, for instance one case I carry it in if I leave the hood mounted it fits very tightly in the case. I worry that the hood may be crushed so I remove the hood and lay it over the lens the same way it comes packed from the factory. Fits nicely that way.

+1...my lens caps are in factory boxes. Most of my lenses are proctected with B&W Clear filter(007).

Well yes, of course. And seatbelts don't offer protection if you're not buckled up.
Yet overall and in most cases, the presence of hood and filter will reduce damage to the lens.

Local independent has removed the filter frame and as I expected, the front outer edge of the lens is damaged to the degree that a filter could be screwed back in - the good news is that the lens appears otherwise fine, but needs sending off to Canon for replacement of the front outer edge (metal bit). I'm told that the Canon could could be in the region of £100-200 depending on the work involved, Canon UK apparently charge £90 to look at it these days though... Fingers crossed for it being just a part swap and and return type repair, rather than anything more serious internally.

I actually leave the hood on as I'm attaching the lens then flip it once securely locked on the camera. There is never going to be an absolute way of preventing all risk but you can greatly reduce the chances.
