Just a little test of my new lens a Sigma 17 - 50 f2.8 ex dc os. I quite like this lens. It's very well built and feels as good as nikons own 17 - 50 lens. Optical quality for still images is in the process of being tested at the moment . But the video looks good, contrast is nice. And if you wanted more you could dial it in o the camera settings or do it in post.
These shots are hand held with the sigma Optical Stabiliser turned on (this helps to keep the camera stable for still photography but also works for video which is great), I think it gave good results for hand held shooting with no planning. As with anything a bit of planning and i should have rested my arm on something as i took the shots. But hey, i'm not judging my hand held skills here.

Sigma 17 - 50 f2.8 ex dc os
I think this lens is very well made. It all feels very solid, as solid as the nikkor 17 - 55mm f2.8 lens which is several hundred quid more expensive. I think i'll run this video through the editing suite again this time colour grading the image and adding some post stabilisation to make it look smoother.
The Depth of focus is really nice on the lens and although the focus has a small motion, turning from close to infinity in just a quarter turn, there is some resistance in mechanism which makes pulling focus quite smooth. The bokeh (the out of focus blurriness) is really nice at f2.8. I'll do more little tests on this lens in the next few days, both video and photography. I'm going to use it to video a few interviews tomorrow!
Anyway this has been a bit tech heavy compared to my usual blogs so if you've made it this far and have questions don't be scared to leave them down below.

I am interested in this lens. But I heard that some sigma lens did not autofocus with live view mode on D7000. Is this video taken on live view mode?
ReplyDeleteYou can only record video in live view mode. But this video is all manual focus because auto focus looks rubbish when shooting a video. The sigma lens auto focuses nicely in live view mode, though. I've noticed that whe using face priority mode the af is slower when there are no faces in view. Probably because it's looking for faces first, then focuses on what your pointing at.
ReplyDeleteHope that helps.
Any more questions or videos test you'd like to see guys just let me know.

Good quaility there mate,never really had a lot of look with Sigma lenses.The last one i had was the 50-500mm it was never really as clear at 500mm as the Canon 100-400 L is at 400mm,good lens though wa sreally naffed off when my 50-500 braoke earlier on this month.
ReplyDeleteThis is my first sigma lens and I'm loving it. Quality for what I do is spot on. Though im sure if you where to print billboard size images you'll notice a difference between this and the nikon gold band 17 - 55.
