• UPDATE



    The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being.

    I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure.

<p>We’re told that Sigma will announce the 85mm f/1.4 DG Art series lens in late August, in time for Photokina in Germany. Availability may not be until early 2015. Perhaps this is to steal some of the thunder from the expected Zeiss 85mm f/1.4 OTUS lens that will be announced at Photokina.</p>
<p>It’s also possible that Sigma will announce something like a 300mm-600mm supertelephoto zoom lens. Although that may not come until 2015. There was no mention of whether or not the lens would have a constant aperture, or even what the aperture would be.</p>

Looks like Sigma will have to deal with AF reports first and check this before release of the 85mm f/1.4 Art. This is not good advertisement for Sigma and their products.
My 50mm f/1.4 Art does not have AF problems. I am extremely happy with my copy.

I thought all the Arts were very, very well reviewed. Are you saying there is an AF problem with the 35 or 50 Art lenses? And is it something the USB firmware tool cannot fix?

Just to be clear, I do not have AF problems but at least 2 forum members here experience AF problems - there is a thread about it.
It is about the 50m f/1.4 Art and not the 35mm f/1.4 Art.
It just seems that there is a chance to receive a copy that suffers from AF problems. Given the history with the previous 50mm f/1.4 of Sigma, also AF issue, it is not good advertisement. It does not mean that it is consistent with AF problems. But the doubt is there....
And so

My price prediction: $999.99. It's like a staircase of $50 increments from the 35mm to the 50 mm to the 85 mm.

n=2 data points are hardly enough to suggest further data points.

it needs only 2 points to draw a straigth line...
so it is entirely possible.. the question is how accurate predictions based on this will be.

I do not doubt you one bit, but I have to ask if this is a case of confirming that 'buying third party lenses is risky' or that we now hold new offerings from Sigma to a spectacularly high bar for AF. Sigma has burned folks before on AF, but so has Canon.

Virtually every review of the Sigma 35 and 50 Art ranges from very good to stellar. The only thing I've heard is this passage from TDP:

http://www.the-digital-picture.com/Reviews/Sigma-50mm-f-1.4-DG-HSM-Art-Lens.aspx
(go to the butterfly mouseover interactive section and read the text above and below it)

I know this is a Sigma 85mm thread, but I am still trying to gather if the boogeyman of 'bad AF of Sigma lenses past' is fair for their more recent glass. From a how-I-think-it-will-work-right-now (without any testing) standpoint, I would argue native Canon lens AF is usually innocent until proven guilty, yet with Sigma, it often seems the other way around...

Look, I bought the 50mm f/1.4 Art and I am extremely happy about it. I would say, you need a 50mm? Try the Sigma because it doesn't mean you get one with AF problems.
If the Sigma 85mm f/1.4 Art will get the same review praise as the 50mm f/1.4, I would buy it - if I would need this focal length

I'm pretty sure that I could find two people that have focus issues with any lens that's mass produced (this includes Canon, Nikon, etc.)

Or even people with more than one Canon lens with which they have focus problems.

Does that mean we should all stop buying Canon lenses?

The biggest issue with the new Sigma lenses is that they don't have the word Canon written on them. ;D
