Polarizer Filter & Graduated ND Filter

[miki33]

Hi all

i own a 550D with 18-55mm kit lens and Tamron 18-270mm F/3.5-6.3
i would like to get Polarizer filter and also graduated ND filter

mine canon kit lens is with 58mm filter size while Tamron is 62mm filter size
i'm planning to get filter adaptor and step up or step down ring

anyone can advise me, should i get the filter size 62mm and get the step down ring or vice versa?
Any model recommendation?

thanks

regards

Can you use CPL on your kit lens? It's front element rotates when you half-press the shutter to focus. Well, unless you are happy to do manual focus.

No experience with step-up/down rings, but I think the latter will cause vignetting...

Get a 77mm CPL filter and two step-up rings (62mm-77mm & 58-77mm). Makes life so much easier.

Wait a minute, I think Cokin filters also can't be used on the kit lens, for the same reason that the front element rotates. Can somebody please confirm on this?

If my guesses are right, then the TS just buys 62mm filters for the Tamron...

all polarizer is the same...need to twist left twist right ...

What I mean is, you rotate the polarizer, get the right angle; then you press shutter to focus... since the kit lens rotates during auto-focus, the polarizer's angle will be out.

hi

if this is the case, what brand is recommended?
i mean since the lens will rotate?


Aren't the bigger filter size much expensive than smaller filter size?
as advise by Ralverd to get a 77mm CPL filter and two step-up rings (62mm-77mm & 58-77mm)?
will this more expensive?

Generally, it's always safer to get the largest size filter and then buy some step up rings to the lens filter you have. You must remember there is always the possibility that you may upgrade your lens in the future and the better lens are generally with 77mm filter. I would go with that plan and never have to worry about buying other lens in future.....just buy step up rings( roughly cost about rm 20-30) to suit the newer lenses.

Just correct the filter after focussing. Shouldn't be a big deal.

applies to all no only cokin...

Since the kit lens will rotate, you buy filters for the Tamron, which is 62mm thread size.
For CPL, Hoya multi-coated should be good enough. As for graduated ND, I have never used one and can't recommend. Beware of the fake filters out there...

Hi Fong

Did you mean only cokin cannot be used with kits lens?
