My wife runs a local thrift shop and someone dropped off in donations a set of 62MM close up filters. She paid 25 cents for them and brought them home to me.

They are three filters in a leather case and are marked as follows:

Fuji Photo Film Japan - Close Up #1
Fuji Photo Flim Japan - Close UP #2
Fuji Photo Flim Japan - CLose Up #5

#s 1 & 2 are about 1/4 inch thick and #5 is 1/2 inch thick and aoppears to have a light green filter screwed onto the front of the close up filter...not sure about this as it not marked and may be part of the #5 package?

The only 62MM lens I have is the Sigma 30MM f/1.4. Will these work with that lens? Is there any instructions as to how one uses filters such as these? Are they worth 25 cents?

Thanks,

Yes, worth more than 25 cents, good deal. You can use them on the 30mm but may not like the results - you'll be too close perhaps. Using some step-up rings you could also use them on any lens that takes smaller than 62mm filters, like your 85/1.8 which will produce nice results. Get the light green filter off though. They can be used in different combinations as well.

Gasrocks,

Not really my thing...I have the 100MM Canon Macro for my macro photography.

If you want them you can have them for 25 cents plus shipping :) I could FEDEX them for +/- $10 bucks I would guess?

Jim,

I notice you have the 100 macro, but if these are decent quality, they make a good "poor man's macro" for someone. I bought a set, cheaply, from eBay for use when I had the Pro1. This shot was done with my 50 f/1.4 and 3 Hoya close-up filters.

Close up filters effectively alter the focus distance of any lens to the focus distance of the filter itself! Doubling the focal length of the lens it is use on will alter the MINIMUM magnification obtainable, but the max magnification does not double, although it is increased.

Focal length to subject (mm) = 1000 / Diopter rating

Magnification = image distance / subject distance

So with a 2 diopter filter and 50mm lens:
FL = 1000 / 2 = 500mm; then
Mag = 50mm / 500mm = 0.1x

Thanks guys,

I am putting them in the mail to Gasrocks in the morning. He is going to use them in his photography classes he teaches.

I keep hoping that some day my wife will come home with a Lecia lens or two from her store. At least these filters have found a good home :)
