Two weeks in the past, DPReview discussion board member Stig Nygaard made a submit within the Canon EOS R Discuss discussion board inquiring why the product web page and all accompanying data surrounding Viltrox’s AF 85mm F1.8 lens for RF mount cameras was now not accessible.

Over the next days, numerous discussion board members speculated the explanation all point out of the product was eliminated, with many coming to the identical conclusion – that Canon should’ve informed Viltrox to stop promoting the product or face some form of authorized consequence. Because it seems, that seems to be precisely what occurred, based on a Viltrox consultant.

The unique discussion board submit from Stig Nygaard.

Two days in the past, on August 27, DPReview discussion board member lowkeyguyo shared a submit with a picture displaying a dialog he had with a Viltrox consultant on Instagram. In it, the Viltrox consultant stated the corporate has ‘been informed by Canon to cease promoting all RF mount merchandise.’ As such, it ‘won’t launch RF associated data on the official [Viltrox] web site’ and suggests individuals who want firmware updates for Viltrox’s RF mount lenses e-mail ‘information@viltrox.com’ as a substitute.

The consultant went on to say it’s ‘not the primary firm to be stopped’ and says it could rethink ‘if Canon opens up permissions sooner or later.’ In a remark to DPReview, a Canon consultant stated ‘No remark presently.’ Now we have additionally contacted Viltrox for additional data

The follow-up submit from lowkeyguyo with a screenshot displaying the Instagram DM dialog he had with a Viltrox consultant.

Assuming the data from the consultant is true, it’s nonetheless unclear why Canon would concern such a warning. Previous studies have recommended Samyang acquired the same discover from Canon after asserting its 14mm F2.8 and 85mm F1.4 AF RF-mount lenses. It’s unclear whether or not third-party lens producers utilizing digital connections with Canon’s RF-mount alone is the problem or whether or not it’s the code, reverse-engineered or in any other case, enabling AF that’s inflicting the problem.

Because it stands, with Viltrox’s 85mm F1.8 AF lens out of the dialogue, solely guide RF-mount lenses stay accessible to buy from third-party producers (barring second-hand gross sales elsewhere). This alone suggests some form of limitation with both the code required to energy the AF performance contained in the lenses or a difficulty with utilizing {the electrical} contacts in any respect.

The Viltrox 85mm F1.8 AF lens makes use of the 12-contact array utilized by first-party Canon RF mount lenses.

DPReview discussion board member antonio-salieri notes the lens’ metadata reveals it as a Canon EF 85mm F1.8 in captured photos, which may counsel Viltrox is illegally utilizing older EF-mount code from Canon’s personal 85mm F1.8 lens to energy the AF protocols in its AF lens. This, nonetheless, has in no way been confirmed and sure by no means will probably be, until Canon or Viltrox explicitly come out and say as a lot.

What is obvious is that until Canon reverses course and begins licensing its AF protocol expertise to third-party producers, it seems as if any third-party lenses with native RF-mount AF assist gained’t be making it to market.

Apparently, the Viltrox AF 85mm F1.8 RF II Lens for Canon RF remains to be accessible to buy from B&H Picture for $399, though it’s not clear how for much longer you’ll be capable to buy it.
