Replacing them is often equal to the cost of the lens...especially a zoom lens.<br /> I'd get a clear or a UV filter.

chris_leck Posted October 21, 2009 Share Posted October 21, 2009 <p>In the past, I always used UV or skylight filters to protect from damage. However, filters can damage images due to reflections. This is true with the best filters (presuming that Nikon and B+W make the 'best' filters). Lately, I have tried to avoid these filters, especially indoors.</p> <p>My somewhat casual testing indicates that filters introduce problems in many circumstances. I do professional stage work. Filters tend to produce unwanted reflections from stage lights. They also tend to add reflections to many kinds of contra-light.</p> <p>OTOH, I have shot in Oregon rain and snow (where one needs to continuously mop water from the filter or lens), in the SW US in adverse conditions, even Egyptian pyramids in blowing sand. I have had to replace filters due to damage (damage from sand, cleaning, cheaper filters, etc.). I've not had to repair filtered lenses.</p> <p>I have also damaged filters due to impacts denting the rings -- meaning that it was impossible to screw anything into the outer rings. Not necessarily carelessness, but things happen if you are out shooting. Lens repairs would have been more expensive than filter replacement. Lens shades reduce the possibility of this, but I didn't always use them.</p> <p>In summary, I suggest avoiding filters unless protection is paramount. If you use filters, employ the best. Lens shades supplement protection, but the primary use of them is to shield from off-axis light (where their use is variable, especially with zooms). Regardless, I almost always use a lens shade these days. YMMV.</p> <p> </p> Link to comment Share on other sites More sharing options...
kivivuori Posted October 21, 2009 Share Posted October 21, 2009 <p>Hi,</p> <p>Maybe this article can help you. I have used high quality filters last 40 years and only few times there have been flare etc. because of the filter. When I´m at sea I always use filters to protect lenses against salty fog.<br> http://www.lenstip.com/113.1-article-UV_filters_test.html<br> BR<br> Esa Kivivuori<br> Hyvinkää, Finland</p> <p> </p> Link to comment Share on other sites More sharing options...

oskar_ojala Posted October 21, 2009 Share Posted October 21, 2009 <p>Long lens users don't need filters because Nikon's superteles have a simple flat front element, call it a built-in protective filter. I don't know if this is the case for all big glass, but IIRC all the current ones have it.<br> Regarding ghosting and flare, this is highly dependent on the combination of lens and filter. It can't be generalized that filters cause/don't cause flare in backlit situations, this depends on many things.<br> I don't have filters for all of my lenses, I never take all of my lenses with me anyway. But there is crud that builds up on the glass up front. Typically it's dust, but could be pollen, seawater, rainwater, whatever.</p> Link to comment Share on other sites More sharing options...

Jim_Tardio Posted October 21, 2009 Share Posted October 21, 2009 <p>Thanks, Lex. But it's the real world outside of "controlled tests" that presents an opportunity for damage.

My real-world experience (40 years worth) is that protective filters cause more damage than they prevent - but I'm not going to say this is the norm, because I don't have any controlled experiments to demonstrate this one way or another. It's likely that a protective filter will prevent some damage, also likely that it will cause some damage but <strong>without controlled tests you cannot predict whether in a particular scenario a protective filter will cause or prevent damage.</strong> I'm not advocating for or against the use of protective filters, I'm advocating understanding the risks and benefits. Anecdotal evidence whether mine or Jim's is not evidence at all.</p> Link to comment Share on other sites More sharing options...
lex_jenkins Posted October 21, 2009 Share Posted October 21, 2009 <blockquote> <p>The poster didn't ask whether others believed in the efficacy of protective filters. He asked for suggestions on what filter to buy.</p> </blockquote> <p>Good point. I contributed to the usual pro/con filter debate with my own first post.</p> <p>I've had very good results with B+W, Hoya, Nikon brand and even Kenko's budget lineup of UV, skylight and protective type filters. Even the low priced Kenkos have been much better than the Tiffens. For some reason all of my Tiffens have become hazy over the years. For what it's worth, my older Vivitar filters, most dating back 20 years or so, are still in excellent shape - no haze, and the coating was reasonably resistant to flare. And I've never experienced any flare with the 52mm Nikon L37c, an excellent but rather expensive filter.</p> <p>While the Kenko I use with my 28/3.5 PC Nikkor lacks the sophisticated multi-coating of the better filters I've been able to induce flare only in one specific situation, and that was a deliberate choice. I wanted to echo the iris-shaped opening at the peak of the tall metal sculpture outside Fort Worth's Modern museum. Leaving the filter on was necessary to produce the multiple iris-shaped ghosting pattern.</p><div></div> Link to comment Share on other sites More sharing options...

joseph_smith3 Posted October 21, 2009 Share Posted October 21, 2009 <p>Regarding reflections, I do remove my KR 1.5 filter during sunrise and sunset shots to prevent the reflection of the sun ruining the shot. And I would do the same in any shooting situation like others have mentioned. I just find it so much easier to clean the filter than to clean the lens.

david_klaffenbach Posted October 21, 2009 Share Posted October 21, 2009 <p>Hey Lex, Nice idea about using the filters to intentionally add flare. I have some cheap filters in a box somewhere. I wonder what else they might be good for. Vaseline soft filter? Crossed screens?</p> Link to comment Share on other sites More sharing options...

Jim_Tardio Posted October 21, 2009 Share Posted October 21, 2009 <p>No real need for an argument, Douglas. Of course I don't <strong>know</strong> what would have happened every time something happened, but I do know that I've had several damaged filters...mostly from inadvertent impact with something. One time it was a urinal in a public bathroom (watch where you swing that camera when you unzip!) And I can safely say that the front lens element would have sustained some kind of damage had the filter not been there.</p> <p>Therefore, based on my repeated experiences, I keep a filter in place. Besides, I usually wipe off the filter many times throughout the day, and I'd rather it be the filter & not my front lens element.</p> <p>Incidentally, I don't use UV filters...I use the clear ones.</p> Link to comment Share on other sites More sharing options...
stephen_worth Posted October 24, 2009 Share Posted October 24, 2009 <p>I don't like to stop shooting to clean my lens out in the field. If I use a plain multi-coated protective filter, I can quickly wipe the dust off with a shirtsleeve and keep on shooting. I've never had any problem with filters affecting image quality.</p> Link to comment Share on other sites More sharing options...
