Dunno if they have what you need but the Hoya HD3 UV is a helluva filter. I have 'em on all my lens. Harry

The last thing a valuable lens needs is less protection.


You are correct. And the debate goes on. The direction and force will determine the severity of the damage and what kind of damage. A filter or lens hood does not do much for a 30 foot drop on to concrete. Good chance both the lens and body are "toast" along with the filter and lens hood.

But most of the "blows" to my cameras have come from around 45° to the edge of the lens. If the filter just cracks, it did protect the lens. But if it splinters, if the force is strong enough, the splinters can damage the front element of the lens. If it was a stiff plastic lens hood, where the plastic eventually breaks but does not splinter, there is less risk than with a splintered filter of damaging the front element.

My lenses have banged into walls, doors, fences, etc. and the lens hoods have managed to protect the front lens element of every lens I have owned for the last 47 years. Some of the lens hoods I have had to file down the damaged edges to prevent from cutting my hands. The worst damage was when I fell on my camera after tripping. The lens hood absorbed the force to the lens/filter while the back of my hand absorbed the force to the body. After I got up off my camera, the only damage was to the lens hood and not my filter (an expensive B+W Kaesemann polarizer) or the lens. The filter was stuck on the lens and could only be loosened up with more specialized equipment on the cruise ship. But a nail file took the sharp edges off the lens hood and the filter has never stuck again. If it had just been just the filter, it would have likely broken the expensive filter, splintered it, and damaged the front element.

I also do not recommend falling on one's camera. A camera does not fit one's body very well.

Pointless essay as applies to the thread. Applies to nothing going forward. I do sympathize with your sorry experience. Ive destroyed lotsa stuff over the years. The details dont matter. Schidt happens. Keep calm and carry on.

I DO believe that there are good reasons to have a filter on your lens when the environment demands it. And it WILL save your lens from damage from abrasive dust, salt spray, acidic fingerprints, and other noxious substances when they are present. But that's not what I hear from people who claim that the filter saved their lens.

I DO NOT believe that a filter will save your lens from impact damage. Sure, there are people who had a filter on and something hit their lens and broke the filter but not the lens. That fact DOES NOT prove that the filter saved your lens. The impact might have been light enough that your lens would not have been damaged if the filter were not present, but heavy enough to break a thin piece of glass in front of your lens. After all, the front element in most lenses is much thicker than a filter. So it would be easier to break a filter than the lens.

I am an experimentalist. In order to prove something you have to do repeatable experiments. A single instance of your filter breaking and your lens not breaking does not prove that the filter protected your lens. To prove it, you would have to do experiments with and without the filter, and vary the impact strength to determine at what point (1) the filter will break; and (2) the lens will break.

That experiment has been done.

So, keep your filters on your lenses to protect against inquisitive dogs, speedboat wakes, tumbleweeds, and the like. But don't tell me that they will save your lens from an impact. If an impact is strong enough to break your lens, a thin filter will not significantly reduce the strength of the impact.

Amen. Point by point. Word for word.

Worse yet is the mention "statistically". Thaz essentially the confession of a clueless slinger of toadall BS.


Before becoming caustic, did you ever consider some folks have viewing problems and maybe caps help them, or as in this case , a simple mistake... Everyone jumps to unfounded accusations and want to roast someone.

When you remove your filter,
that's when your photography will shine.
Then you can work on points for style.
Like the club tie, and the firm handshake,
A certain look in the eye and an easy smile.

Unfortunately, this question, operating to protective filters, usually opens up a can of worms and as you can see the "shouting and counter- shouting has l already started.

The anti-filter came to insist that protective filters will introduce flare and negatively affect sharpness. The pro-filter folks remind us of the possibility of serious lens damage due to various impacts, dust, dirt, great fingermarks, etc.

Technically speaking, anything you place in front of you, even the finest optical glass coated filter can possibly cause the aforementioned issues. A poorly crafted filter will certainly do so. I high-quality filter such as the kind made by B+W, Zeiss, and other reputable and time-honoured manufacturers will usually NOT cause any perceptible loss of image quality.

As for wide-angle lenses, B+W has a very comprehensive stock of THIN filters for wide-range lens applications. Also, note that with ultra-wide-angle lenses LENS SHADE usage can be problematic. The shade would have to be very large and shallow to preclude vignetting, the same problem caused by a filter in a thicker rim or made of thicker glass.

So, here is my personal experience. I do quite a bit of industrial photography on construction sites and other hazardous environments. I am dealing with airborne particles, metal filings, sparks for welding, sawdust, etc. I will use the protective filter in those situations. Over the years, 5 filters needed to be replaced because of damage that would have seriously harmed the front element of my lenses. I have made extremely large prints for trade-show booth displays with no loss of quality due to filter usage. You have used the filter on your other lenses, so I assume you are satisfied withte the quality.

A serious head-on impact or dropping a lens on a hard surface will cause serious damage regardless of filter protection. If the filter is shattered, the shards of glass will, in turn, damage the lens. A lens shade may prevent scratch of the lens by heavy brush or sharp twigs in the woods, etc., but again would not abate a head-on impact.

Here is a link to a very comprehensive website. It explains the thin-filter usage and has a handy "vignetting" avoidance tool that will hel you determthe correct filter for your focal length and filter mount diameter.

I agree, my only difference is that I use a CPL on all my lenses and I put the lens hood on when I'm using the camera. In low light situations I may remove the CPL, but I always leave the lens hood on.

I don't use protective filters at all. just lens hood always, I find shooting through inferior glass or plastic filters make me wonder why I spent good money on expensive lenses. I have never scratched or damaged a lens with a lens hood on. Just my two cents.

I thought additional feedback is in order.

Because the objective is so much smaller than the lens barrel on this lens, the lens hood is not that big and very small when backward.

A good multcoated UV filter has little if any impact on image quality, unless shooting with bright lights or sunshine. In those cases, I take it off to avoid flare.

A protective filter keeps the objective like new. I think of it as a lens cap that I can shoot through and don't have to obsess about protecting and clean with utter care.

Thanks all for the thoughtful feedback and amusing banter.

I have a simple checklist

Shooting in industrial and construction locations- there is are airborne particles, sawdust, metal filings, welding sparks, etc., PROTECTIN FILTER ON ()

Shoot food in industrial and restaurant kitchens. There are fumes for cooking, the danger of splattering frying fats and oils, steam, and sprays. and heat, etc., PROTECTION FILTER ON ()

Shooting around spraying water such as ocean surf, covering a foreground scene, water sports, PROTECTION FILTER ON ()

In-studio and most out-of0 doors portraiture. FILTER OFF (). In all the years I am working, I only had one kid projectile vomit on my camera!

Product shots, still life, etc., NO PROTECTIVE FILTER.

Landscape and exterior architecture- In rough terrain FILTER ON (), in most urban and suburban settings FILTER OFF ()

Lens shade- all the time- I can think of any occasion where I need to stay lig striking the lens. In the studio and on-site, I tend to like dramatic side and backlighting so the deepest lens shade possible is my usual approach. As for les protection? Yes, it can preclude finger smudges and certain scratches, however, if the shad is big enough and firmly mounted, it can exacerbate damage if the camera/lens is dropped or impacted against a hard surface.

These skinny filters. What is the big controversy? Unwanted vignetting is NOT usually caused by the poor light transmission in the edges of a clear high-quality filter. It IS caused by the rim or edge of the filter entering the light path at the periphery of the frame, thereby acting as a gobo. It may not be apparent in the viewfinder with the lens wide open but as the les is stopped down it will come into focus and cut into an appreciable portion of the image. It can more easily occur with a wide range of ultra-wide-angle lenses. Depending on the focal length, the design of the filter mount, the adapter rig, if any, and the (not advisable) stacking off multiple filters. Vignetting can also be caused by an inappropriate lens shade. A thing filter may or may not be requr for any particular setup and a filter of regular thickness may work. It depends on all of the aforementioned factors.

If you use high-quality optical glass and coated filters of the proper size for the application, they should not cause any interference or serious loss of IQ.

If you must have a rule of thumb. approach filter like medications. You need to weigh the benefits and possible side effects and make a decision.

Shootg in a war zone or covering a violent riot? well, the last the yoy need to worry about is gettg your lens scratched.
