Yep, they are typically made 0.2mm too thin to "guarantee" to be able to focus to infinity. May negatively impact optical quality of wide angles with CRC to be off this much.

Dear Mr Andrew Reid, First, let me state that we deserve to be spanked for the quality problems with the initial batch. We had no excuse for having shipped it, that was a grave mistake and poor judgement on our part. We issued a recall before anyone had received the shipment, but by that time it was already too late. We learned a lesson from that and we sincerely ask for your kind forgiveness. We admitted to our mistake in front of the world by issuing a recall and we want to be able to move on. I sincerely wish one day we would be unshackled from this historical baggage and focus on bringing the photographic/cinematic community more new and innovative products, instead of draining our energy dealing with this PR stunt for the rest of our existence. Due to extreme shortage of our stock, we may not be able to fulfill every request even if it is from a member of the press. That you were not afforded the opportunity to use the latest fixed adapter for your review was unfortunate, but our hands were tied and we were not doing that to you or eoshd on purpose. I hope you would understand that point. I was not sure what you meant by being badly treated. If you meant the hassle of having to ship it back, you could have refused delivery of the defective unit and have it returned to sender. If you had not done that, Metabones promised to reimburse return shipping. If by having been "badly treated" you meant not sending you a spare review unit, sorry, but we really don't have stock! We @conurus had a grand total of ONE (1) Smart Adapter and that gives you a glimpse of how short we are on stock. Sorry, but we really didn't mean to not cater to your needs but we really, really have no stock in order to be able to help you. Unfortunately that means you would have to return your unit first and we fix it, but sorry we don't have a spare to help you with your downtime. You as a member of the press and we as a product innovator both share a common goal: it is in the best interest for both of us for reviews to be up-to-date. Neither of us want outdated information to be reported. As this incident proves, that is very hard to achieve unless you discuss and communicate with the manufacturer. Conurus had never received any email from you until today. Granted, I was not sure what exactly happened on the Metabones side, but generally, they forward us every customer email that we would need to act upon. In any case, if you had in fact informed them about the ghosting issue they would have told you that a remedy was readily available. While we were not able to provide you with the spare review unit, at least we would have been able to provide information, if you had asked for it. Anyway, I wish to express my appreciation for your blue ink update of your ghosting problem report. When I called Metabones on the phone, I was told that every adapter returned for firmware update also received anti-reflection treatment at the same time. Are you sure the cinema5D unit really had no anti-reflection treatment? If that was indeed the case, I will call them again to find out why any Ver.01 adapter would have received no anti-ghosting treatment. Conurus delivered Ver.01 to Metabones on January 30 and I would need to discuss with them and find out exactly when the anti-reflection treatment was first shipped. (I was under the impression it was before the firmware, but I could be mistaken on the exact date.) Bo-Ming Tong Founder Conurus Vancouver, Canada

Update: just spoke to Metabones on the phone about this ghosting incident. I was told that the name "Andrew Reid" was a very familiar name to them, as they have already printed out the shipping label for you and will ship as soon as your adapter is returned for firmware update. They said your adapter never came back - which implied your adapter may be missing the black felt treatment that everyone else had, and it may imply that you are reporting is a problem that we resolved over a month ago. Please advise us if that is not the case.

Dear Mr Andrew Reid, First, thank you for your reviews and criticisms. We @conurus discovered the internal reflection issue in January and immediately notified Metabones about it. Metabones' remedy was to apply black felt material on the inside of every adapter. Again only the first batch was shipped without the black felt material treatment and had a problem with internal reflection. All subsequent ones shipped in February and March were shipped with the black felt material already installed. All customers who ordered the first batch of adapters have been notified to reject the delivery and return the adapter to sender. For those who have taken delivery and subsequently returned the adapter to Metabones for firmware update, Metabones took that opportunity to install the black felt material in order to curb the internal reflection problem that you found. Our testing concluded that after the black felt treatment the adapters no longer suffer from any internal reflection or ghosting problems, and thank you wondo for confirming that with his/her Canon L glass. So Mr Andrew Reid, please kindly advise if your optically defective adapter had the black felt material installed. If not, it was a negligence on the part of Metabones' firmware update service for which Conurus would apologize on their behalf. If the black felt material is already installed and you still experience a problem with internal reflection, please advise us so and we will have to go back to the drawing board and redesign the adapter. We appreciate all constructive criticism. We are always listening and gathering end-user feedback from various sources, including monitoring the Internet for new forum posts, blogs and reviews (such as this one). Even so, the quickest way to get a problem resolved is to contact Metabones directly. Excuse me for stating the obvious but it is *us* who correct and fix problem. Even if all the rest of the world is aware of the issue they would not be able to do a thing to address it. If you find something, please let us know directly. If the first thing you do is to post it, we may not always be able to find your post and as a result we may not always be able to resolve the issue. If you always directly inform us about issues you find, not only us, but the photographic/cinematographic community at large would be very much appreciated!

Thank you very much for your suggestion. A comprehensive list of tested lenses have been added to the product page on our web site. As of today we have 47 lenses in the tested lenses list and the community added another 15. The list will keep on growing as we test more lenses ourselves and receive more reports of success.
