I put a UV filter on my 18-140 lens and noticed it took 3-5 attempts before the focus locked on target correctly.......took off the filter and things worked fine.

Is that normal? If I use a filter should I be focusing manually?

Should I even bother with a UV filter.....did it mainly for lens protection but...

off the subject at hand, I attached a shot of my grandson that I am rather proud of all things considered.

Never had an issue with a filter on and to be honest the only time I use a protective filter is in real rough conditions with lots of dust, sand or the possibility of salt water exposure. Most or 95% of the time I just use the lens hood and cap.

Art, get control of your lenses before they get arrested :lol: :P

Seriously that is odd. Never had that problem with a UV filter. Try a different brand.

For bump protection, just use a filter ring with no glass. I had an 80-200 with a UV on it that took a hit. The filter shattered and I had to have the lens disassembled and cleaned. Wasn't cheap.

Digital: D610 backed up by a D1x.  Quoted from an unknown source by a fellow planeteer, "Never get rid of a working D1x." I've got to agree.

Film: N90s, F3, F100, F4s, C330s. A few lenses.

Why film photography? I like shooting with the equipment. 6x6 Velvia slides from a C330 have an appeal all their own.

Why automated 35mm/Digital cameras? Event photography is about capturing moments. It often requires quick response. Well done automaton can be your friend or your enemy. It all depends on knowing what it can and can't do. "A man's got to know his (camera's) limitations." paraphrasing Dirty Harry...

Hi Ed,

Firstly, that is an excellent image!

 

That is unusual, what brand of UV filter?

FWIW, you do not need a UV filter on a digital camera but there are "protector filters" available to protect your lenses from a harsh environment, like salt spray, blasting sand from the wind, chemicals etc,

The best way to protect your lens is from having accidental damage clause in your insurance

If you feel happier with a filter, thats OK as well, we all have our own personal preferences (I have a 14-24 so I just try to be careful  :) )

 

Lastly, if you have a polarising filter, make sure it is a circular polarising filter as some linear polarising filters can cause focus problems,

I haven't seen this personally but be aware it can happen

And if you put a "high end" protective filter on a cheap lens, like the AF-S Nikkor 50mm 1.8, the filter may cast more than the lens!

......Gary

Art, you too? It must be catching. :)

Ed, like Art, I don't use protective filters anymore. I used them for the longest time - until I realized that the happiest person was the sales guy at my local camera store. PP can look after haze and I always use a lens hood.

Despite the above, filters are useful. I have several ND filters plus an ND grad. If I ever stop buying bigger toys, I'll be buying a Lee big stopper, for long exposure photography.

If you disagree, I suspect you'll have lots of company. This debate has been going on for some time. :)

First, nice image.

 

Second, well, everyone already said what I also do, not have one. I use a lens cap most all the time. And buy a new one when I lose it. I have hiked over rocky places and banged my camera and lens a few times.  B) And, while my tripod head did not survive a clusty mountain biker, my camera and lens did.

 

Is the filter dirty? Even a thumb print? Does it do it all the time? Your pretty near the sweet spot of a lens at f5.6. And, looking at this sample, bright sunlight, it might be possible that you got interference from smudge marks and sun going through the marks. I have never heard, or had happen to me a focus problem with a filter.


Thanks, Dennis.

Forgot! 

LensCoat sell neoprene covers for all size lenses, cheaper than replacing a Nikon lens cap

One place you DEFINITELY want a UV or Skylight filter is at the beach if there's high surf. It's not so bad on the Great Lakes (yes we have surf -- have seen 10-foot waves on Lake Erie), but when you're at the ocean, there's an oily / salty film that'll build up on the front element from the surf spray. Having the camera in a plastic bag and a UV on the front element can save your gear in such an environment.

Lots of great information here, and for that I thank you all.....I will take note of everything, but for now I should say I ordered the filters out of desire and should have done a little homework first and saved the money. I do have lens hoods for both lenses now and will use those first and foremost. One day I will experiment with the filters just cause that's how I roll...lol

Thanks for the nice words on my grandson's image......He has seen them all.....(I took several) The black and white one I felt attracted to the most, but they all look good I think.

I think there is something else going on if you are having a hard time locking focus.  I'm not sure what focus mode you are using, but if the AF sensor is not on a good AF target, or if you are using a group of AF sensors, the camera can have a hard time with focus.  What AF settings were you using?

 

Just about the only time a filter is likely to affect AF accuracy is shooting into the sun with a low contrast scene or lots of lens flare.

That was my thought too, Eric. Filters are tested to NOT affect focusing. My shorter lenses have filters for protection from elements. 300 and 150-600 are "hood protected."

I cringe every time I clean those huge front elements.

I am not a big fan of cleaning glass.  Something about touching them.  I typically blow dust off and only clean the odd finger print I accidentally put on it.

Well, my fingerprints aren't "odd" like yours, Art... they are usually just big and dirty.
