Which diameter filter

[Fermat]

Hi all,
Having lenses with front screw diameter for filter 82mm, 72mm, 67mm and 52mm, i would like to buy 3 filters yellow, orange and red to cover all the lenses with rings Adaptor.

What do you suggest as a diameter for filter? 86 or 82mm?

Thanks
Mario

All of my filters are 67mm and I use adapters for some of my lenses as you suggest.

Therefore I would use 82mm filters if possible - provided adapters are available.

If 82 mm is a wide angle lens and you need all of the lens coverage, then get 82 mm thin filters. If you don’t need all of the image circle then rethink your needs.

Yes 82mm is a WA.
What do you mean with rethinking my needs?
Thanks

Since your widest lens has 82mm threads, if you want filters for all of your lenses, then they probably need to be 82mm.

However, that is pretty expensive.

If cost is not a problem, then use 82mm.

Tell us exactly what lens has 82mm threads. Sometimes, the threads are wider than what you will need, and it might be possible to use a step-down ring to a small thread. That will save you a lot of money. I have a very-wide-angle lens with 82mm threads, but I can use 77mm filters on it without a problem.

If you are shooting 4x5", you won't have a problem using 77mm filters on this lens -- which are much less expensive, and in a wider selection.

You will need to get step-up rings to 77mm for your other lenses.

High quality filters are a long term investment that can last and be used for decades. With this in mind, 82mm high quality filters are preferred (penny wise_pound foolish). They can be obtained new or good used. Minor surface defects are not going to make that much if any difference in the image quality recorded on film.

Anti-reflection coatings on the filter surfaces can and do reduce light flare impacting image contrast. The other image quality aid is using a GOOD lens shade, ideally a proper adjustable compendium lens shade. If presses, shading the lens/filter with the dark slide can do ok enough.

Alternative to 82mm filters with step down rings to fit other lenses in the set, 100mm or 4" square filters with the appropriate filter holder works very good too. Exampled in post# 92 of this previous discussion.
