I have a decent supply of Takumars that I use with my Pentax DSLR. All I want is something 1. That doesn't get in the way of my setting the aperture on the Takumar; I don't want to shoot wide open all the time on my E-PL3 2. That isn't ridiculously huge ore heavy (otherwise, I'd just use my Pentax K-r) 3. That isn't going to get stuck on my camera, or require shims, paper, etc. Just something I can put on and use reliably. Ideally, recommendations would come with links. p.s. Tellng me "lots are available on E-Bay" isn't helpful. I want to know what people actually have with their Takumars. Thanks.
