    I found an Olympus OM 28mm 3.5 at my local Goodwill for $5, so I obediently bought it. I'm not sure how these lenses work, though. It's got a nice clicky aperture ring, but there doesn't seem to be any way to keep the aperture set at the desired setting, unless you depress a small, spingy button on the barrel near the lens mount. I can't seem to switch the lens to a manual aperture mode.

    Looking online for adapters, the ones I found don't seem to have aperture settings, so my question is, how the heck do I select aperture if I mount this lens on an adapter?

    When the lens is attached to the adapter, it will stop down as you turn the aperture ring. That is the way mine works, so I assume any other adapter will work the same way. I paid about $23 for a Rainbowimaging from a "large online retailer" (not sure if we are allowed to mention the name).

    Most adapters have a little arm that actuates the aperture for you.

    I figured this particular adapter would be one with an aperture adjustment (unlike the two other adapters I have for other mounts) but the OM adapters I see online don't seem to have one.

    The ones with aperture control built into the mounts are ones where the aperture is not in the lens, or cannot be controlled manually (Nikon G, Pentax 110, Canon EOS, etc). When on the adapter, the spring you mentioned is constantly depressed, allowing you to "see" the aperture change.

    Just get a standard adapter, rainbow imaging is where I have bought all my adapters, you'll love the OM glass, its sharp, smallish, and a joy to use, I have OM glass from 24mm to 300mm and can't seem to let any of them go.

    Ah, you've got on my point of confusion, thanks much! I'd better hop on Amazon then...

    Have you compared this lens to the Konica Hexanon 28mm 3.5? I have one and love it, for all applications f5.6 and upwards, f3.5 is useless due to softness that I'm pretty sure is a by-product of adapting. If the OM Zuiko manages to be crisp at f3.5, though (or even passable) it might get to go places more often than the Hexanon.

    Sorry to thread spoil, but what's people favourite OM adapter? I have a Fotga one, and the aluminium at the m43 end is wearing/shearing away... not good... I'd love to get the official Olympus one but the €€€/$$$s are a bit too high!

    Actually it was $9.99, but "housewares" were %50 off. I even asked my girlfriend if I could get it, she just commented on how I always manage to find awesome deals!

    Who doesn't like paying mere pennies for state of the art glass and metal optical instruments of intricate contemporary and historic value? Until my collection gets physically large enough to look like I have a problem... Then she might actually realize I've been 'converted.'

    I've been plenty happy with my Fotodiox branded OM-m43 adapter (as well as their EF-m43 adapter)

    I have rainbow imaging and have no complaints. Another popular one is the fotodix

    Thanks, might give one of those a go. Is the material the m43 end is made of good and solid? Have you noticed any wear at all out of interest?

    There's a bracket on a proper OM adapter that sets the lens in manual mode, allowing the aperture ring to control the iris. Shown in attachment. If you check the ebay adapter pics, they all have it.

    I've not seen the anodized aluminum on my adapters show wear, but don't expect much for the $10-15 that they cost.

    That is such a low-tech solution. I love it.
