Hi members!

Just released a new podcast moments ago. It's on neutral density filters, and graduated neutral density filters, polarizers, reverse grad filters and more. It's an interview with Darwin Wiggett and I think it turned out quite well.

77 – Neutral density filters – Graduated neutral density filters – Interview with D. Wiggett (http://www.photography.ca/blog/?p=681)

Thx all!

Thanks for another great podcast Marko. Is it possible to use a polarizing filter on my kit lens where the front element rotates? will it just be a case of focusing the lens first and then adjusting the filter before shooting?

My pleasure on the podcast.

"front element rotates" :confused: Which camera and lens do you have?

What exactly does that mean? Is there no threading at the front part of your kit lens to attach a circular polarizer.

I have the Canon 450D with the kit 18-55mm IS and the canon 55-250 IS (both have the 58mm thread) As the lens zooms and focuses the front of the lens rotates, and so does any attached hood or filter.

I made the mistake of buying a petal hood, and it doesn't work to good due to rotating with the front of the lens. So now I am waiting for some 'tube' hoods to arrive.

Once it finishes rotating though why can't the attached threaded polarizer work? what am I missing?

I don't think your missing anything, Just me being a bit slow, so I focus the lens, then rotate the filter...

cheers..

Cool, as long as you can still use a polarizer :highfive:

I can't believe I asked such a stupid question...

what do you do on every lens with polarising filter?

focus the lens, then adjust the filter...

It's really strange when mfgs do this...both my cheapie kit lens and my not-so-cheapie replacement zoom have non-rotating front elements. I zoom and focus and it stays right side up. Having to chase and catch up with every single frame would make me squiggle-eyed.

But when your autofocus is on, you'll still have a lot of trouble because it is constantly focusing... That is my experience.:confused: I don't think one can use PL efficiently on moving subjects.

Thanks for the heads up Yisehaq,

I see your point on moving objects... I guess a lens upgrade would be the only real solution. Also the canon hoods don't screw into the filter thread, they sort of screw around the out side of the lens front, so reaching the filter to rotate it will be a bit tricky.

I think for the moment, for me a polariser will be most useful on stationary shoots where I have a lot of time to set-up the shot. ie. landscapes.
