Filters

[am7787]

So I'm somewhat new to filters in general and had a pretty simple question, hopefully at least.

Basically I have a Sigma 28mm f/1.8 prime lens. I want to buy a UV filter and may a ND filter, but am totally oblivious as to how to make sure the filter is the right size if I'm buying online. Do I just look for a 28mm filter? Or are there other way filter makers market their products compatibility.

Also any middle of the road recommendations that wont break the bank?

Thanks Guys!

28mm is the focal length: filters are measured by their diameter. If you flip the lens upside down, you should see a symbol that is a circle with a line through it, then a number. That's your diameter for the filters.

Hi am7787,

I really like Tiffen filters. They have varying models and one of the best priced and working polarizers that I've found. It was about $80 with a 77mm thread (you can look up the filter size on the camera companies website). Brands are personal preference but I think they make a good product for the price.

Thanks,

Wow, 77mm? I like Hoya filter, different brand makes different grade of glass on the filter. You can get a Hoya (hd) 20 bucks filter that had cheaper glass and it thicker and heavier or get the better one Hoya pro1 digital I think, are made with better glass and thinner.

B+W makes great filters too.
