I'd be happy to pay the reviewer what he paid for his to use it on my PEN. ;-)
Originally posted by Blue A person just posted a review of the Auto 110 70mm lens based on m4/3 via an adapter and gave it a 6. I have used all of the 110 primes and have no doubt the 70 is the best of the bunch. The problem with adapters is that most are homemade and the registration distance needs to be perfect. Plus, there is no way that the aperture can be adjusted meaning the lens is only usable at f2.8. There are ways to use disks but then again that is also going to affect design parameters just like improper registration distance would.

Edit: for an article or thread about the "experiment" would be fine. However, to rate a 110 film prime via an adapter to m4/3 lenses is stacking the deck.
