New Sigma 120-300mm 2.8

[An Exception]

This Sigma 120-300mm might be the long lens for me when I finally get a telephoto. Judging by Sigma's recent quality revolution, I have high hopes for this. (looks nice as well)

Well Sigma are using the term "almost prime quality in a zoom", so I'm pretty optimistic that it will be good.

Most of Canon's primes don't have sealing either though to be fair.

I wish Sigma would sort out their quality control issues on some of their lens.

I'm in the process of sending back the Sigma 1.4 50mm as I'm not after trying to create a hazy dream like photograph.

I'm giving them one more shot before I throw the towel in. The 50mm is riddled with people complaining about AF issues or soft issues, seems like Sigma haven't done a thing about this.

+1 completely agree, quality control is their main negative.
It took 3 attempt's to get an 85mm 1.4 I was happy with (one was truly FUBAR), but I was very happy when I did get a good copy (although I have the Nikon 1.4 now).

Most of the issues are with simple front or back focus (not really a physical fault and easy to correct), did you try to micro adjust the camera to suit the lens? I'm not saying you should do that and keep the lens, but at least that way you can see if the IQ of the lens is up to your expectations.

Most of these issues will be a thing of the past with the new USB dock thing. Due to this I would say it's highly likely you'l have less trouble in the future with Sigma lenses than buying first party lenses.

Imo, it is luck of the draw with any lens, especially fast primes. Just from my experience you have to be a little luckier with Sigma.
