step-up or step-down rings?

Showing my ignorance here. Oh, well.

I have the 18-55mm kit lens (52mm ring) and have just ordered the DA 55-300mm (58mm ring). I need to get some filters. I don't know if it makes more sense to get 58mm filters and a 52-58 step-up ring for use on the 18-55 or to get 52mm filters and a 58-52 step-down ring to use on the 55-300mm. The 55-300mm will have a hood, obviously, where the 18-55 kit doesn't, if that matters.

I don't have a wide angle lens yet but like landscape photos. I'm sure I'd like a polarizing filter for use on the 18-55 until I get a better wide angle zoom or prime in the future.

Any advice is appreciated.

I prefer step-up to step-down. Smaller filters cost less than larger filters, but you're less likely to see vignetting with step-ups. That said, I've used my Raynox 150 on my DAL50-200 with a 52-43mm step-down ring and had no vignetting.

HTH!

Honestly, if you're going to go the step-up route (much better option) anyway I'd say go with 77mm filters and step up rings for the lenses you have. Filters can be spendy, SU rings not so much. One filter for all your lenses.

Add a rubber lens hood and you're good to go for almost any lens you ever use now or in the future.

YMMV

In general I advocate keeping it to two sizes: usually the biggest of your smaller filters (Say, up to about 58mm) and then about the biggest of your larger-threaded lenses, if any.

In this case it's just possible you could share a stepped down 52mm polarizer between those two lenses, and this would work with the stock hood of both. Could be a handy combination. (That is, if the stepping-down doesn't vignette on your tele. Maybe someone who has that lens can try. )

Either way, I wouldn't go out of my way to deal with (and pay for) a big nice polarizer before you actually have a lens in that size range.

I got a 58mm Polarizer and a 52-58 step ring to do exactly what you are trying to acheive

The cost difference of a 52mm CPL and a 58mm CPL is only 10 bucks (eg B+W).
I regularly use the 55-300 with the 58CPL with hood as normal.
I dont use the 18-55 much and only once used the 52-58 and the 58CPL (no vignetting issue obviosly). It actually fits under the 18-55 hood but is damn near impossible to screw in with the hood already on (fat fingers), so I used without the hood.

Would have though that vignetting would be and issue on the 55-300 using the 52mm (?) and you're only saving max $10 if you get the smaller filter.

Agreed. Why buy that filter multiple times anyway?
