Sigma MC-11 Mount Converter?
« on: March 05, 2016, 04:14:18 PM »
With the arrival of this mount converter from Sigma - presently being released in 'Sigma' and 'Canon EOS' mount to Sony E - I'm wondering what other A7 series owners are considering doing?

"The Sigma MC-11 Mount Converter allows the use of Sigma’s Global Vision (e.g. Sport, Art, Contemporary) range of Canon fit lenses on Sony APS-C and full-frame E-mount compact system cameras. The MC-11 Mount Converter incorporates the digital data necessary to support fast, smooth autofocus performance when used with a compatible camera body."

As it appears to allow ALL (or nearly all?) inbuilt focus functions - eye focus etc., - that the a7 series cameras have, is it worth 'dumping' the LA-EA3 & 4 adaptors as well as Metabones etc., and getting all the functions these others don't give? These 'functions' being built in to the mount itself which can be updated via USB. It's seeming somewhat bazaar that Sony can't (?) make one that allows all the functions when using A mount lenses but Sigma can - even if only, at this time, for their own mount and Canon!

I'm starting to think this is the way to go and sell up all/most A mount glass I have and change over to either Sigma mount ART glass - - - but in Sigma mount or EOS? The Sigma ART glass gets rave reviews in most cases and is better priced than the forthcoming FE GM appears to be priced at.

Others thoughts?

 I'm sticking with what i have for the time being but it certainly opens up some interesting options particularly in the Sigma Art line of lenses.
 I'm sure the FE GM lenses are very good but the prices are rather crazy.

With posing the question it means I'm still waiting to see how others feel when they get to use it - with it being 'pre-order' at the moment on the WEX site.

I've got the LA-EA4 + the range of A mount glass (Minolta, Sony, Tamron, Sigma) listed in a previous post. I'm feeling somewhat limited because of the unavailable bits using the 4 - - - did try the LA-EA3 but wasn't impressed and this Sigma one appears to open up a whole new area for getting the best for available focusing areas etc.

If it was released in the Nikon mount I may have been drawn to that - - - my son having (had) to go to that brand for use in his Uni course - - - either Nikon or Canon for FF to make use of the other kit available at the Uni. He still has his Sony 77ii and glass plus a few bits of my glass :( :)

Sigma / Canon - - - which mount? Hmmm... Either one would mean they'd be 'my' glass and not 'borrowed' by my son.... hahahaha

Frank, I see you point and agree to some extent, however I personally have no plans to dump my LA-EA4 anytime soon. I admit that it has some limitations with my A7, principally No image stabilization with A mount glass. I don't know if that limitation could have been avoided if Sony had wanted to. If so then that would help confirm my suspicion that Sony are more interested in selling cameras than they are in keeping loyal customers.

More to the point, the sigma MC-11 Mount Converter together with all the other adapters that are available will no doubt allow Sony to sell more cameras at the cost of Sony E mount lens sales. I can't see Sony standing for that for long though. Lenses are a big part of any camera makers business and I wouldn't be surprised if, at some point in the not so far future, they modified their future cameras to prevent the use of third party adapters. That may or may not be possible but knowing Sony's abilities and propensity for innovation, I am sure it is. They still have to build up their lens base for mirror-less cameras and these third party adapters help keep them in the game until they do so. But make no mistake, that is probably the only reason they are allowing it. Some time in the future they will correct that, as I said above.

Then again, perhaps Sony have decided to be good guys and help Sigma, Canon, Nikon and all the others sell lenses, while they concentrate on cameras only? Somehow I doubt that, Sony want it ALL. :|

Sony will try to make it difficult for them as much they can for example after body firmware upgrade the camera will not communicate properly with lens adapter.

But sigma was smart enough to put USB port for future firmware upgrade. This is going to be a push for Sony to release all functionality that Sigma adapter MC-11  offers and will offer.

The temptation is still there to go down this road but I'm hanging back a while until I see/read 'reviews' of how it does in others hands before I decide on the glass to go for. I've no intention of just dumping all the 'A' mount glass I have with having the LA-EA4...

The Sigma 'ART' range does appeal, gets very good reviews and is reasonably priced when compared to the 'native E/FE mount glass... and prices being given for the new GM glass put it a bit out of reach - hence the appeal for good quality and priced glass. Some initial reviews do say ALL Sony A7 mount menu lists are accessible with this mount (for Sigma ART and Canon glass) which aren't with the LA-EA4 'A' mount: eye focus etc.

Okay... only touted as for Sigma mount or Canon mount glass at the moment - - - not Sony 'A' mount which is disappointing and would prove to be an easy fix for many 'A' mount glass owners :(

I'm still undecided - should I decide to go for this later with more feedback available - on the mount to go with? Sigma's own mount or Canon mount? Canon of course would give me acess to all the glass available in that mount... si is probably a 'no brainer'? :lol:

I've no problems with you posting here if you want to John. I wouldn't see it as a 'hijack' and would be interested in the discussion going further :)
