Sigma 50-100mm f/1.8 DC HSM Art Lens 4K Video Test\r
This is the Sigma 50-100mm f/1.8 Art Series 4K Video Test. Sigma Arthas been one of my favoritelens. I like their extra aperture lens idea. It works really well on crop sensor cameras such as the Sony A7RII (In video mode). I dont normally talk about behind the scene. But this video I have to say, it was the longest video test I have ever done. I did not mean the video length. I mean this lens took me over 2 months to work on it. In November last year, I went to Melbourne for a wedding shoot. And after the wedding shoot, I spent over few days in Melbourne to work on this Sigma 50-100mm lens video test. First, I have to mention that I always shoot S-log on my videos. So this Sigma 50-100mm is just the same. I set the camera in S-log 2 and I put the ND filter as usual. Because A7RII does not have camera colour assist. So when it comes to focus, its just very hard. And as you may know, the zoom in focus and peaking are kind of useless when shooting S-log, everything looks like in focus. I see all he red line on the peaking. But when you put it up on your computer. They are just very soft. Over 50% of my video was out of focus. So I had to go back to Melbourne again in December to re-shoot most of my shots. I know I should not be complaining too much because this lens isnt the Sony native lens. So you cant really rely on the auto focus. But one thing I have to say, when its in focus, the image is just very lovely, its really sharp. The image quality wont let you down. But the only down side is the weight. This lens is very heavy. If the lens had the build in IS. Then I would accept the weight. But no IS and no weather sealed and still 1.5kg. Thats a bit overkill.\r
