| p.1 #1 · Bad Sigma 35 1.4 copy? |
I've been testing over the last month or so, my copy of the Sigma 35 1.4. It's an amazing lens, and when it works, takes outstanding photos. I am shooting and testing with a 6D, 90% of the time with center point focus. But here are 3 things I've found that are bothering me:
- When I use live view, it takes a long time to focus, almost as though it's "ratcheting" itself into focus, if that makes sense.
- Often times, I get back focus, where a wall will come into focus before the subject in front of this. Mostly I've noticed this when there's some action/movement, and more so in the horizontal movement between the subject, and myself.
- And finally, focus speed in general is quite slow. Now, I don't have a 35L to compare to, but if I don't pre-focus, it often times will hunt more than my 85 1.8. The 85 snaps to focus extremely quick, even at infinity and back. The 35, easily 4-5x slower, if not more.
That's the short list. Often I find low contrast surfaces are nearly impossible for the Sigma to lock focus on. Anyone else running into these problems? Do I have a lemon? QC issues? What's the course of action for sending it back to get exchanged or calibrated? I purchased this lens over 30 days ago at Adorama. So at this point, assuming I'd have to send it to Sigma directly.
Now, don't get me wrong, this lens takes phenomenal images when it's working properly, or I pre-focus for some scenes. Just these potential QC issues are annoying. Build quality is also quite impressive.
