Understanding Filters

[ReDDoG]

My lenses are the 18-55 kit and 55-250 zoom. Im not completely getting the different filter types .When should i use the following?

1- UV filter
2- Circular polarizer(My lense zoom out but dont spin i think)
3- Mulitcoated filter

Uv is good overall protection right?Circular P. is for shooting skylines with clouds/water shots right?Mulitcoated highest quality glass right?

Main concern is with the circular p. with either of my lenses.Will using a CP on my lense cause damage because it doesnt spin or turn?Ill stop asking questions now because im probably overthinking the whole filter thing.

Thanks

Multicoating applies to any glass you put between your subject and your sensor. Basically, glass is coated with microscopic layers of other material which are designed to prevent reflection at the glass-air interface. Each layer is carefully tuned, and the cumulative effect can be significant. It controls reflections and reduces backscatter which can lead to flare and loss of contrast. Better grades of multicoating on filters also generally go along with better (more uniform and plane parallel) glass. So the good brands/types are B+W's MRC multicoated filters, Heliopan's SH-PMC multicoated filters and Hoya's S-HMC filters.

There are a number of types of filters.

UV is used by many of us for protection against flying debris or small animals/children. It's avoided by many others because they fear it will adversely affect the images they capture.

Circular polarizers are used to control reflections off any non-metallic objects. They work on water, glass, glossy paint, atmospheric particles, shiny hair . . . You will need to rotate the filter for the desired effect. If your lenses (like your 18-55 and 55-250) have rotating front elements, focusing will cause the filter to turn along with the front element, so you'll have to readjust the filter after focusing

I use only B+W MRC filters - UV(0) and CPL (not together though). So, yes, it's a good choice IMHO.

Is the UV something like you use Jon?I wasnt sure about the model number.

Agree, I use the same B+W UV/Haze (MRC) F-Pro filters on all of my lenses.
The expensive Kaeseman (MRC) CPL filter works great.

Yep.

I'm a fan of the Hoya Pro1 Digital UV filters, as they are multicoated and have a thin profile for wider angle lenses. I haven't tried their circular polarizers yet (I've got one on the way), so I'm looking forward to seeing how well it works.
