| 1dx help: squeaking sound (video included) with sigma 35mm 1.4 |
Hey all. Just looking for some input from those that are more experienced.
Some background. I started shooting with Nikon DSLRs, I owned a lot of their cameras (d70, d40, d80, d90, d300, d700, d800). I also have extensively used the D3s, and more lately my friend's D4. I shoot weddings, events, and also do photography when I travel.
Since I wasn't heavily invested in Nikon, I was easily able to switch to canon w/o much loss. I switched because of the mark iii. The d800 just wasn't working with my work flow because of the 36 mp, and I wanted a more well rounded camera. Could have gotten D4 but didn't have the funds at the time. So I ended up with Canon and the mark iii.
Eventually I was able to save up and I sold the mark iii and am now a proud owner of a 1dx. I love it so far. I just have 2 main issues with it thus far and I'm hoping someone can chime in.
1) When focusing, it makes this squeaking sound. I'm not sure exactly where this is coming from. I would guess the lens but when I move the focusing ring on the lens there is no sound. Only when the camera drives the lens, then there is a squeaking sound. See video below. Excuse the quality, just shot it on my cell phone.
*Update: video removed, issue resolved. Lens was defective*
2) Just a general question, it seems like the one shot and servo mode in canon are completely different. The servo mode has a very difficult time locking focus in low light, while the one shot just locks with no issues. I'm not even talking extremely low light, just say like a dimly lit reception hall... I am unable to lock focus at all with my servo mode. I tried using single point spot, single point, single point with 4 and 8 surround points....but no luck still. The camera will just hunt back and forth and won't lock.
My question is, this huge different in acquiring focus between single shot and servo, is this normal? In the D4 there is no difference between the continuous and single mode and both lock in the most extreme low light w/o any hesitation. That's just my one issues with this body, the servo mode in low light.
Overall I do prefer the camera over the D4, but the servo mode has been disappointing in anything but ideal light. I can upload videos to show proof as well.
****UPDATE: it was a lens issue, everything works fine now that lens was changed****
