I have the tamron 17-50 non vc. Would using that to take landscape be more ideal than using my 18-200 kit lens? As i don have a CPL yet so deciding which thread size CPL to get. or should i just get 72mm thread CPL and do a step-up if i want to? Kinda redundant question but i just hope for advisable answers.
 

I'll prolly get a 77mm thread just incase you get another lens. E.g:16-35mm.
That way, you save $ by just getting a ring instead of another CPL.

I will get a bigger size and step up like you said, you can use it with both lenses if you get a bigger size.

Good move, but test first if you can still use a lens hood with the step up ring attached.
 

stepping up is always better than stepping down in most cases.

why do you still wan to use a lens hood when u are using CPL filter? how do u turn the filter then?

With your fingers? Are you a 7-year-old kid who can't find your way around things? It's not very hard to turn the filter with the hood on considering how shallow the hood is on UWA lenses, you know.

If flaring is an issue then I don't see why anyone would have a reason at all to not use a lens hood. It's always best to keep options open rather than stumbling like a fool when you find yourself stumped.

In this regard, Pentax users have it easy...

You don't need a lens hood because you'll shooting at right angle to the sun when using CPL.

Hi bro. For me I only use CPL to cut reflection from the water so it doesn't really matter where the sun is positioned.

I've found myself countless times shooting towards the sun while doing seascapes and flaring can be quite a bugger. The lens hood has helped me in those situations.

Anyway, I'm not saying it's a must to have a lens hood on. We all have different approaches. If TS finds that my advice is helpful then that's good. If TS finds that others is then that's fine as well. Either way, no advice given is wrong.

then ur whole hand will be blocking the lens, and u can see thru the viewfinder to see the maximum effect of the CPL, whats the point? :dunno:

A CPL will not reduce reflection from the water if you point the lens towards the direction of the sun.

I don't know about you bro but I can rotate my CPL easily with just my fingers. I nudge my fingers in the grooves of the petal hood and that's it.

You seem to be right. I'm reading up on it now. Good thing you brought this up. Thanks.
