I have an Olympus E-510 with the 14–45mm lens. I am interested in buying the Cokin P Series Gradual ND Filter Kit with Holder, but it does not say for which lenses it is suitable.

Is it going to be alright or it needs a ring? And if yes which diameter?


As the advert says...

"Everything you need to get started, apart from adapter ring specific to your lens diameter."

Google tells me that lens has a 58mm thread, indicated by the ⌀58 on the front.
[Double check that my info is correct before ordering.]


This is just me, but if you're buying everything new and not adapting an existing set of filters, I think going with Cokin P series is overkill unless you're getting a supertelephoto zoom. You can probably get away with the series A adapter.

The P filters are designed for lenses with a maximum size of 82mm. The A series maximum size is 62mm. The biggest filter ring I've run into on an MFT lens is 58mm. You may still need a step-up ring to use the adapter ring with a particularly small lens, like the m.Zuiko 45/1.8 which is Ø37mm, or if you want to avoid buying multiple Cokin adapter rings.

And the adapter ring is a Cokin adapter ring for the specific series that will fit on the front of your lens, it's not just a step-up ring, but has a flange onto which the holder slots. B&H lists the Series A adapter rings here. If you want to put it directly on your 14-42, then get a 58mm sized one, since that's the size filter thread it takes.
