UV or not UV
UV has almost no effect on digital, so there's no need for a UV filter to improve image quality. You can use one for protection if you like, or a clear glass protector, but one can cause ghosting or slight loss of image quality, and you have another two surfaces to keep clean. Lens glass and c...

It may be illogical, but I would rather clean a filter than the front of a lens.

UV or not UV
Filters break more easily than lenses, and a broken filter can damage the lens underneath it. Also a UV/glass filter can noticeably affect the image in some circumstances. I've never scratched a lens in 26 years, and I've mostly used them without filters. I also don't wear a helmet when walkin...

UV or not UV
The filter issue (to get back to the OP) is an which is unlikely to meet with any agreement. I use them because I usually work in very dirty and dusty places. The argument that it just adds another two surfaces to clean is spurious as only the outside face of the filter gets dirty. I am also pu...

I am also puzzled that people who complain they degrade image quality will happily put a polariser or ND grad in front of their lens. When I can I use Pentax SMC filters and I doubt you could tell the difference. Because a polariser or ND grad adds an effect where an UV filter does so good as nothi...

UV or not UV
The argument that it just adds another two surfaces to clean is spurious as only the outside face of the filter gets dirty. Only if you leave it on all the time. Despite trying to be careful, I've found they get dirty on both sides when removing and storing in wallets. Shine an LED torch on your fil...

I would never say that filter should not be used for protection. I just think there are some reasonable arguments against. Zipper is American for zip. Maybe it's time to shut my zip!

... you end up with quite a pricey filter that only is there for protection... Pentax SMC UV filters are easy to pick up on ebay for less than a fiver. The argument that it just adds another two surfaces to clean is spurious as only the outside face of the filter gets dirty. Only if you leave i...

We will never get agreement over this one. It is always going to be a personal preference based on circumstances. I do agree with that statement, and I wouldn't try to disuade anyone who is happy to use a filter for protection. That's not the point of the arguments. The point is hopefully to help u...

Sadly, tomorrow isn't looking like being a good photo day, apart from the early mist maybe. Best wishes, K. You need a haze filter. :twisted::twisted:

I am in the camp that uses Protect, UV or Skylight filters to protect the front of the lens from dust, scratches, stone chips and splashes. However, I will not use a filter unless it is multi-coated. Of course Hoya, the owners of Pentax are one of the big filter manufacturers. Over the years ...

With the coloured ones I don't have anything to compare them with but as they are just to adjust contrast on BW film I don't think it would matter. With the others, I have neve noticed anything amiss. One looked patchy as if the coating had been rubbed off, but most are absolutely fine. A bit o...

Over the years I have had to replace a number of filters for scratches, chips, and breakages. I am glad I did not need to replace the lenses. Only this week I replaced a scratched filter. Filters scratch and break much more easily than lenses, in my experience.

Filters for DA15 limited?
Check out ebay too, there are usually quite a few filters and they rarely go for much. As Clarky says, I would be surprised if you couldn't get them in 49mm, that is one of the most common lens/filter sizes. K.

How long is too long?? (bulb exposures on K20D)
Coincidentally I fooled around with some 20 minute exposures on a K20D earlier this week. I was trying to shoot star trails at around midnight. Didn't encounter any problems apart from major condensation on the filter which I would imagine has major negative impact on the image. I couldn't tell sinc...
