Filters....use or don't use?

[caa1277]

Is there any point to using filters like UV or polarizing? Just got my first SLR and I know they make them for them, but I've never used one. Any benefit to using them?

UV, not so much. A polarizer can be quite useful to reduce glare. For example, you could be shooting water or a window without a polarizer and the surface will just give you a lot of reflection. Put on the polarizer and you can see what's under the water or behind the window. Keep in mind that it will cut a stop of light when you use it.

I agree with wbeem. UV filters can cause more problems than they solve. But a polarizer is a very handy tool to have in your bag.

I started out using UV filter and now I feel I wasted my money. Photo Chick and wbeem mention polarizer filters which I agree with. Now I pretty much only use Neutral Dentistry filters to slow my shutter speed during the day.

Well I'm glad that I didn't run out and but a UV filter. I may look into the polarizer. I knew I could count on you guys to give great advice!

Any other suggestions or tips with filters?

Used a uv filter for past 20 years on every rebel I've had, don't like pictures without it

The UV filters are no longer necessary. They were a must using film. As film is sensitive to UV light, it would cast a bluish haze outdoors.

Digital sensors have the UV (and IR) filters built right into them. Adding an additional UV filter does nothing to improve the image. Many would argue that adding that extra glass would degrade the photo, make it less sharp or less contrast. Any improvement is a placebo effect.

UV filters (or plain clear filters) definitely increases the chance of flare and reflections in the lens. Here is my mistake. On the left, you can see the reflection of the bright lights from the right. This wasn't a cheapo brand filter either. It was taken with a Hoya UV Multi-Coated filter. Which is now collecting dust.

Polarizing filters can be very useful. Like others have said, they can reduce reflections off of water and glass, or have the sky a deeper blue and vegetation more vibrant. Here are my samples.

No filter

With a polarizing filter

I like my polarizing filter, but you really nned to be at the right angle to the sun. Or maybe I'm using it wrong. See this example where some of the sky isn't polarized becasue the light isn't at the right angle.

Is this avoidable?

Yep. They don't do anything good with digital. And newer films do not have color shift from UV as much as older films so a lot of film photographers forgo the UV filters now as well.

I do know polarizing filters can add vignetting at ultra wide angles. That looks like a fairly wide shot. Maybe that's what's going on here.

I like my polorizing filter....UV I don't bother with anymore.

Like Mom2RTK said, you get this uneven polarization with a wide angle lens. It's not really avoidable, though it can be more or less pronounced than you have here, depending on where the sun is in relation to the shot you are taking. My only advice is anticipate it will happen and either adjust your composition, or use the effect creatively in your composition.

I agree with most everyone about the UV filter. There is only one time that I use it and its only for added protection. I photograph Team Demolition Derby which is run on a wet, mud track. The mud and mud clods are flying everywhere. I can't count the number of times my cameras have been hit.

I use the polarizing filter (and my ND filter) quite frequently for reasons the others have mentioned.

 

[caa1277]

Thanks for all of the info and suggestions everyone. Is there a particular brand of a polarizing filter that is better than another or are they all pretty much the same?

I may get one and play around with it to see how it affects my shots. I'm not afraid of messing up or making mistakes. After all, that is how one learns the best in my opinion!

Digital camera sensors are not sensitive to UV so the filter does not provide a useful function unless we want it only for lens protection. A lens hood usually does better at this and has no chance of degrading the image (unless it vignettes). An inexpensive filter can degrade the image (slightly) and can also cause strange reflections when used in a dark area where there are light sources. This applies to polarizers or any other filter as well but the inexpensive (uncoated) filters are usually the worst.

A polarizing filter is useful for reducing reflections and atmospheric haze as well as improving color saturation. As long as there is sufficient light a polarizer could be left on the lens without any harm although in certain lighting it may not provide any benefit. For most dSLRs a circular polarizer is required, a linear polarizer may affect the focusing system.

Some good brands are B&W, Heliopan, Schneider; many others may be good also but the cheapest ones are probably not so good. They are definitely not all the same, some have color shifts, uneven polarization, glass that causes distortions, etc.

I have dxone the same Terry when shooting side by side mud bog racing. I also have a towel covering the lens and as much of the body as possible. Amazing the places the gets to.

I use my polarizer quite a lot. I just bought the size to fit my largest lens and bought some stepping rings and use it on all of them (except the wide angle).

I used to use UV filters, but no longer do.

I also use a neutral density filter, but that is for very specific situations and not something that is ever fitted to a lens and left on there.

I have a Canon T4i with an 18-135mm lens and a 55-250mm lens. What would you recommend filter wise? Any specific brand?

I've been on Amazon and seen kits that come with 3-4 different filters, but I'm not really sure exactly if they are what I need or if they are any good.

TIA!

I'd start with a polarizer. As far as brands, I personally tend to stick with B+W or Heliopan for filters like this. Buy one filter to fit the largest diameter lens then get step rings for the others.

Thanks photo_chick, I have the same setup as caa1277 and a "nifty fifty" and was going to ask about a step ring. Is there any kind of deterioration in quality with them?
