Question: Which UV filter for my DSLR!?
I want to buy a UV filter for my Canon 400D (aka Rebel XSi), but dont know anything about them!. I cant spend too much, around the AU$30 mark!. Will something in that price range effect the quality of my photos!?

Would one like this suffice!? http://cgi!.ebay!.com!.au/ws/eBayISAPI!.dll!?!.!.!.

Thanks!.Www@QuestionHome@Com

Hi dahnik,

Good choice!. I was going to suggest Hoya before I looked at your link!. Getting the filter from eBay is going to save you some money!.!.!. and the Hoya filters are considered to be very good!. Retail, you would be spending more than what you are here on the auction!. Your photos will be fine as long as you keep the filter free of smudges!.

Hope that helps!.

Hello there!

Since they already have the (very) good answers to your question, I just like to correct the model of your camera which you had mentioned!. Canon 400D is Rebel XTi and not XSi (450D), "misleading you honor!."Www@QuestionHome@Com

buy one for each lens you own, and keep the on all the time!.

that's a good one!.Www@QuestionHome@Com

If you go into a camera store that sells used equipment, there is usually a box of filters sitting out for people to look at and buy!. I get them for $5-10 USWww@QuestionHome@Com

Stock answer alert!.!.!. But it is exactly what you have asked!.

UV Filter

Many people use a skylight or UV filter to protect the front glass of the lens, but you can also buy high quality plano glass filters for that purpose!. Whatever you do, at least buy a decent quality filter instead of trying to get off cheap!.

Personally, I'd say the first place to start for effects is a polarizing filter!. You want a "circular" polarizer!. Check these examples and you will see what it does:

You might also find a neutral density filter (varying degrees of darkness are available) useful for taking shots of bright subjects at wider apertures or slower speeds!.

As far as all the rest, you can do this in Photoshop or Photoshop Elements!. Okay, I don't want to argue with anyone about how it's better to use the real filter, but our asker can try a few in Photoshop (etc) "for free" and see which ones will be the most useful before you start spending money on the real thing!.

Or, go here http://www!.thkphoto!.com/products/hoya/in!.!.!. and see what you can learn!.

Or here http://www!.tiffen!.com/tiffen_filters!.htm!.!.!. Tiffen makes a kit to get you started on filters, if you think you want more than one!. They include a polarizer, a UV filter and a warming filter!. B&H Photo and many other places sell this kit!.

Many people use a UV filter simply to protect the front element of their lens from damage!. "UV filters absorb ultraviolet rays which often make outdoor photos hazy or indistinct!." (from: http://www!.thkphoto!.com/products/hoya/gf!.!.!. )

We get this question often enough that I decided to upload a sample to Flickr showing the same subject taken with and without a UV filter!. Download the image, cut a small section out of the top half and drag it to the same section in the bottom half and see what you think!. The photos were taken about 15 seconds apart in subdued sunlight, so I think the lighting was virtually identical for each!. There was no post-processing at all so you can make a fair comparison!. I will not comment any further and let you decide for yourself if there is any color shift!.

The picture was taken with a Nikon D200 at ISO 100 with the Nikon 18-200 VR lens @ 112 mm at f/5!.3!.

Here's a comparison that I did by accident!. Read the comments and you'll understand:

Buy a name brand like Hoya or Tiffen!. Don't get cheap junk to put on the front of your fine lens!. Personally, I am now switching over to plain high quality optical glass "filters" from Nikon for lens protection, even though they cost more than a good UV filter!.Www@QuestionHome@Com
