<p>Would anyone be able to confirm whether all the 6x6 Mamiya TLR c330 lenses have aperture 'click' stops or do some have 'friction' setting? would appreciate help, many thanks Stephen C.</p>

<p>I've got a 65 blue-dot that has click-stops, but my 135mm black barrel lens is just a friction slider</p>

<p>Eric, Thanks for your response, I have just purchased a 55mm f4.5 black Mamiya TLR Wide angle lens and it has friction slider aperture control, while the black 80mm f2.8 lens I have is 'click' stops, I was not aware of these differences in the Mamiya TLR lens lineup, not that there is that many! Many thanks, Stephen C.</p>

<p>It's a difference in the shutter units, really. The Seikosha ("silver") and Seiko ("black") shutters in the Mamiya TLR lenses are the same as the shutters in the Mamiya Press lenses, which I have. Some of the Seiko shutters have click stops on the aperture ring, some (the earlier ones, I believe) don't.</p>
