lens reversing ring

Hi all.

im after a 49mm ring to use on a A28mm lens (has aperture ring)
I bought a 49mm lens reversing ring off ebay for about £3.00, but i have been sent a 52mm ring. It doesnt seem very good quality, and it is really difficult to get it on one of my 52mm thread lens.

I was wondering if anyone can recommend a decent quality one.....i would rather pay a bit more if it was better quality. Any recommended sellers?

I dont really want the 52mm one, and cant be bothered to send it back (i dont want to use on my DA lenses due to no aperture ring), so if anyone wants it let me know. You can have it free, and free postage.

Cheers,
simon.

You could get or use a 52 to 49mm stepping ring.. Best of both worlds then..
