Purchasing older Lee Filters - Questions
« on: March 21, 2018, 02:44:14 AM »
I have an opportunity to buy a decent sized set of various 4x6 Lee Filters for a reasonable price. Apparently, however, the filters are about 20 years old and haven’t had much use.

Has their been any major changes to these things in the last 20 years? I profess my ignorance on Lee Filters, having always just opted for the traditional screw-in ND filters.

Is there anything I should watch out for with older filters in general - I.e., scratches, etc?


Thank you in advance.

Scratches. Most Lee filters are resin filters. Exceptions include Big Stoppers.

Thanks. I appreciate the response. I'll examine each filter before I go through with the deal.

OK. Firstly I'm connected (not an employee) to Lee Filters so let me answer some of your questions.

As long at the filters have been stored properly then they will be fine. A simple test would be to set-up a white background and check via the meter if NDs are altering the stops i.e. is a .3 ND / ND grad altering the exposure by one stop, two for .6 and three for .9 etc. This cannot be done for Big Stoppers /Super Stopper  your need to carry out a long exposure so download the Lee Filters App. for the little stopper / big stopper / super stopper, these filters are glass and the dyes used will not alter. 

Check for deep scratches (slight surface marks will not generally photograph or create flares as the plane they sit in is too far out of focus). The resin filters are made from the same resin used to make prescription reading glasses, and are of a type that resists yellowing from UV exposure just like reading glasses.

Lastly make sure they are flat and have not been exposed to long term higher than normal temperatures which could create a bow in the resin.

Other than that happy shooting.
