UV Vs Skylight For L Lenses

Thu Feb 23, 2006 6:51 pm

Hello all,

I've just bought a Canon 70-200 F4 L, and now I'm a bit confused about which filter to buy to protect the front element. I know there are UV filters and Skylight filters, does anyone here knows the difference between these two types? Which one to get?

Also, is there a recommended brand and filter model thats better? I'd like to protect my investment, but also don't want to degrade the picture quality by getting a bad piece of plastic in front of great glass.

Advices, anyone?
Thanks in advance

I'm not a big fan of filters.
When i first got my 70-200 i also put a filter on the front of it and i lost a lot of shots due to light bouncing of the filter and back on to the lens.
If you are shooting with the hood on i don't see the need to protect the lens as the hood does a good job.
Anyway enjoy your new lens and happy shooting.

I agree with JumboJim747. A filter will protect your lens from mishaps, but may degrade image quality. Every added layer of glass risks to increase internal reflections and diffraction.

If you are decided to use a filter, buy a good-quality one - they are not cheap. Whether it's UV or skylight will make no difference on a digital camera.

I used to have filters on my lenses. They now make excellent drinks coasters and my lenses produce better images without them.

Get a Hoya or B+W filter. They don't degrade image quality at all. The Skylight adds a slight warm tone. There's clear filters too.

I use UV filters for protection, I wouldn't feel comforatble without one on the end of the lens, as the camera gets put down all over. Skylight filters have a slight rose tint to them, which a digital camera will automatically try to correct, but the difference is hardly noticable.


Obviously missing something....

I always use B+W MRC (multi resistant coting) for the protection of the lens. My advise is not to save money on a filter, that would be like a Ferrari with cheap tiers  Smile. UV filters are IMO the best, they don't have a color tone. Skylight filters have a brown/red colortone (with are filtered out with a dSLR) but always costs a little bit of light (however you won't notice this)

I have just bought a Hoya Skylight for my 28-300L and so far see no problems with the results. It cost £20 on ebay (new and unopened).

In relation to the cost of the lens, a filter is small change. I would suggest you Start with a Hoya and then if you dont find it to be satisfactory go upmarket to a Pro filter, (Or alternatrively if you decide you dont like filters at all just stop using it!!!) Most serious photographers use some kind of filter to protect their investment unless they have very deep pockets.
