    This lens was manufactured in the mid-80s by Cosina and sold under various brand names (Cosina, Vivitar, Exacta and even Carl Zeiss Jena). It's rumored to be very sharp. Despite it's macro designation, it's not really a macro lens, but it focuses really close for a wide angle: its MFD is just 15 cm from the image plane, which is impressive.

    My copy of the lens is labeled as Exacta and comes in the Canon FD mount. I bought it for about $12 to replace my late Tokina 24mm f/2.8 which drowned in the Dnieper 3 weeks ago. Actually I wanted to buy the Canon FDn 24/2.8, but couldn't find one in time for upcoming holidays. I will be mainly using this lens in my film setup, but also did a couple of test shots on my GH2 to see if it's really good.

    What can I say? I'm very impressed. The lens is already sharp (but slightly hazy) at f/2.8, and at f/4 it's very sharp.

    This one was shot at f/8 to achieve reasonable DOF:


    Full size:

    And this image shows sharpness in the center of the frame at f/4 (this is 100% crop):


    The bottom of the "GIII QL" badge is soft because of limited DOF, not because the lens is soft.

    Just to add to this, in the UK this lens was also sold under the Miranda brand (like Exakta, another defunct camera brand resurrected for re-badged Cosina products). I've not tried this lens on my Olympus, but natively on my Pentax it really is sharp and I'm struggling to find any evidence of CA whatsoever.

    A really, really great lens for £30... now I just need to get a K-m4/3 adaptor :smile:

    It depends on what mount your lens is in...

    I got hold of one of these (the Miranda version) years ago from eBay. Used it quite a bit on my old OM-2, and now it's spending most of its time attached to my new OM-D as a 50mm(ish) equivalent, until I've saved up enough for the Panny 25mm, or indeed an Oly 25mm 1.8 if/when it ever appears...

    Here are a couple of macro examples of literally what was in front of me at my desk... :smile:
