slrclub (via dicahub) reports that Sigma will launch a universal lens conversion service. All Sigma lenses with 10 contacts can be easily modified to get another mount type, except for Nikon/Pentax version of Sigma lenses. For Nikon/Pentax versions, the aperture will be controlled mechanically after the conversion. There shouldn’t be such issues with Canon/Sony/Other versions of Sigma lenses. Tomorrow we will know more, since Sigma will officially announce the service on August 1st. The service will start from 9/2.

Wow!
Tamron, tamron, where’re you??
Also for mft?
Boring, my Sigma lenses have precisely the mount that I want them to have.
Then get the fukc out of here and go to a place where they talk about your mount. Everything is a fukcing negative comment around here
Luckily, we get to enjoy your positive comments.
My Sigma lenses already have an MFT mount 🙂 I didn’t mean it in a negative way, at least not as negative as some of the other posts on this site.
The irony.
I did not write that. It’s sad that you have to use my name to try and put me down.
Unfortunately not really useful for M43, as these lenses are presumable not really good for CDAF.
I’ve read somewhere that the conversion is possible from NEX to m4/3 and vice versa, so whoever has some of those three Sigma mirrorless lenses and can afford to spend a month without them, can have his/her lens with the other mount. Almost as useful as Samyang 16mm F2 in m4/3 mount if you ask me…
What is “9/2”?
9/2 is February ninth, or September second, whichever seems most likely. 🙂
or just means four and a half 🙂
So you will not need to sell your Sigma lenses if you change system, seems a smart move IMHO.
Regarding the asumed high costs of conversion, there are only very few lenses worth to be switched to a new system.
It is a step of sustainabilty that would fit much better to Leica oder Zeiss lenses.
This hurts my feels. For years I have always thought Nikon/Pentax are the only companies to do it right with the aperture control.
Does the service include 4/3 and m4/3 mounts ??
admin, you forgot to mention this: “the mount replacement service might be free, but you will still have to pay for the shipping and handling to Japan.”

Slow AF or not, the prospect of buying a brand new 120-300/2.8 or a 500/4.5 and immediately have it converted to 4/3 or m4/3 seems rather mouth-watering. After all, slow AF might be better than no AF.
Pimp my Glass
Does this mean the Sigma 18-35mm F1.8 DC HSM that is available only in APS Canon, Nikon and Sigma mount could be converted to m4/3 mount?
We will likely know the answer to that in about a month.
I would love to have an m43 mount version of the 50-150 2.8

but I suspect those who say it wouldn’t AF well are correct. But a fast 100 to 300mm equivalent would be a killer sports lens if it did AF quickly.
