Effects filters ?

[Florida_Bear]

Further on to my thread about my old flash gun I have also come across some effects filters that I used with my old film SLR.
They dont seem to work to well with my 350D.
Any ideas anyone ?

In what way don't they work?

Size? =)

Polarising filters can be odd with new autofocus systems, if thats one of the problems. They need to be circular polarisers not linear.

Thanks Andy.
For example I have some 'shape effect' filters, ie the shape of binoculars, key holes various shapes etc.
When I use them the shape is not clearly dined as it was with my film slr and is all blurred around the edges.
I have a prism and starburst filters that work fine.

I wonder if it's due to the different size of the imaging sensor (smaller than a 35mm film neg) and changes in focal lengths on DSLRs?

Did they come out sharp before?

One wonders how the focus would work with shapes right smack on the lens.

Have you tried manually setting a wide aperture?

See more...

Hmmm, I havent tried the aperture yet.
Funny enough Andy, I was just searching through some old photos and found some where I had used the filters and they did indeed come out sharp.
