Thanks for all the info. Appreciated.
Idk but the entire thing just rubs me the wrong way. Here I am looking to spend nearly $700 on this somewhat high end lens yet we have all this talk of how it might not be ok and I might need to get some USB dock, if it doesn't work consistently just "send it back", Sigma is telling me it’ll be fine yet im reading from real users that it probably won’t be and will need AFMA, etc. If this were a $100 lens thats one thing, but at putting out $700 I have to be honest its not very appealing.
With all this talk, I have to ask since im still new to this world…. Are Sigma lenses considered slightly less desirable than let’s say Canon, Fuji and other well known brands lenses?
Canon lenses will almost always be guaranteed to work on Canon bodies, same with Fuji lenses on Fuji bodies. Third party lenses don't have this guarantee. If fact, some of Sigma's film era lenses (Canon EF mount) do not work properly on modern digital Canon bodies (camera body gives an ERROR message and aperture doesn't stop down) because of a Canon firmware update. This was not really Sigma's fault, and they did address it with some kind of fix (probably firmware update in which you needed to send the lens to Sigma). However, this fix was for a limited time and they do not accept older lenses anymore.
At one point in time, Sigma lenses were considered inferior. However, that is not the case anymore. The problem is Sigma offers far more APS-C lenses than Canon. And they are extremely well made and extremely sharp, for what seems to be a bargain price. Sigma has no competitor with their 18-35mm F1.8. Same with the 30mm F1.4. Canon has a 28mm F1.8 and 35mm F1.4. The 28mm is inferior and the 35mm is so much more expensive. That is why some of us live with the occasional AF miss.
Sigma reverse engineers Canon AF protocol and they use existing Canon lens data to fill in the protocol data in their own lenses. This is probably why it sometimes has issues with AF. We don't hear as many AF issues with Sigma lenses on Nikon bodies.
If possible, try to test a copy of Sigma's lens with your camera and see how it performs. Some shops will have a sample lens, or if a friend owns one, even better, and borrow it for a day or too. If these are not possible, you could purchase the lens and return it, if you do see issues. This is time consuming, but at least you know what to look for.
