Expensive glass + cheap filters
Would a cheap filter, clear glass for example for protection only, ruin the image quality of an expensive lens?..

It certainly would do much harm to image quality...wether that would be too much is up to yourself. I definitely would never do that (and stick to my B&W filters)...

So more expensive filters (for protection purposes) wouldn't affect the image quality of the lens at all?..

I personally wouldn't put a cheap filter on an expensive lens. That just seems common sense practice to me.Nikon D60 18-55vr & 55-200vrSB400Casio Z750..

Any time you put something in front of the lens, it will effect the image quality. A lesser quality filter will have more of an effect that a higher quality. A cheaper filter may or may not create images that meet your satisfaction - it depends on your taste. Other factors such as the lighting, depth of field, subject matter, etc. will also have an effect on the quality of the image..

What do you consider an "expensive" lens? If you're spending $1,000 or $2,000 on a lens, is there a reason you would want to put a "cheap" filter on it?.

Seriously - protection filters are highly overrated. A good lens hood offers better protection..

Feel like reading conflicting information for the next month, search this forum for similar posts. Define an expensive lens and define a cheap filter..

With the exception of two of my wide angle lenses for my rangefinder kit (a CV12 and CV15) and my Tokina 10-17 fisheye zoom, I've had a filter on each of my lenses. If the filter gets scratched, ruined or compromised in some fashion, I replace it..

Expensive glass + cheap filters. you are wasting the quality of the expensive glass. everything is reduced to the quality of the worst item in the optical stream. the best glass in the world is no better than what you have attached to it...

When I first satrted in slrs 38 yrs ago. I had protective filters on all lenses. I now have filters on none. and at no time in that 38yrs stretch has a single lens been damaged in any way for any reason. it ended up as a cost that I just did not have to pay...

From what I have heard and read, consider yourself very lucky. It just takes one time to ruin a lens..

You won't get reasoned answers if you start by asking if it "ruins" the image. Of course it doesn't "ruin" the picture. And, apparently, you will find those who swear any filter degrades the image - so spending outrageously for filters may not help either ..

The answer is someplace in the middle. Under some conditions, the poor optical characteristics (color, not "flat," coating performance) can degrade the image. As can poor post processing, lack of color calibration, bad printer/paper matches, bad room lighting, etc. It might be apparent that many of the same characteristics which are so abhorrent to the folks who don't like "protection" filters, it's the uncommon (if not unavailable) polarizer or ND grad type filter which is the highest quality glass, has super coatings, etc..

Hoods won't protect under all conditions, filters, especially uncoated filters, can add to flare, reflection and contrast problems..

There are times that it makes sense to consider using a protective filter. I tend not to but if around a lot of blowing dirt, sand, salt spray, etc., then I'll usually use one. Other times, general day to day, I don't...

I don't have 38 years experience, maybe more like 32. I've not ruined a lens nor protective filter given reasonable care and use of a lens hood. The only time I advocate protective filters is with water spray, particularly ocean spray, or dusty windy conditions. When I do use protective filters I use the best I can find. Top end filters last long and they're simpler to clean well. If you're going to buy insurance in the form of a protective filter be consistent in your logic and buy the best insurance. YMMV...

So, in order to have a paper thin filter to protect a lens, as if it would, you'd be willing to put up with a lifetime of lower contrast, sub-par images? No thanks.Cheers, Craig..

Depends on how you use the equipment also. If I were a shooter that stayed in the studio I would never have one on my lens. If I were back in the Amazon as one time where I found myself stuffing cameras and lenses into bunches of bananas on a small boat being pulled over by a Columbia patrol boat in Peruvian waters ( to people were killed in that area the year before by military just for their cameras)...then I would (as I do now) have B&W filters on my primes.'The moment you think you're great is the moment you quit learning.'http://www.gawalters.com..

Because I like travelling a lot, I keep filters on my lenses (different circumstances in jungle/desert/cities/etcetc). Highest quality (B&W) uv filters will not degrade your pics/lens...

LOL...There have been times when I wish I had been. In that case there was no good place to go. They were taking us down into their boat one at a time. I asked a guy in my boat that spoke english that if he heard a "POP" what was he going to do. Going overboard into the river wasn't a good choice either..

All went well and were sent on our way but I had some camera cleaning to do...

ALL glass in front of a lens will degrade the image, and a poor quality filter will degrade the image most of all..

Having said that, most filters are okay but it seems like false economy to spend large amounts on a lens only to lose the benefits by skimping on the filter. Some of the best filters on the market are made by B+W and Hoya and have some of the best multicoatings to reduce flare. And although in theory, these filters WILL degrade the image, the effect is negligible...
