Sony A5100 with Sigma 18-35mm f1.8 and Sigma MC11 adapter

Sony A5100 + Sigma 18-35mm f1.8

In this video I am testing the Sony A5100 with Sigma 18-35mm f1.8 + Sigma MC11 adapter, how well it can autofocus and also using it for actual job to see how well it actually works. I was quite surprised with the result and footage I have gotten from this combo. So if you are afraid of the autofocus not working, you don’t need to be, the video autofocus with surprisingly fast, much faster than I expected it to be. However the downside of the combination is that the Sigma 18-35mm f1.8 is quite the noisy autofocus lens, rendering the sound recorder inside of the camera unusable.

The autofocus for photo is not bad, but still usable for casual photo, but not great if you are going to do sports photography with this setup. But for the more casual photographer and portrait photographers this lens is able focus well and fast enough.

Surprisingly this lens is much brighter than I thought it would be, as I was surprised I was filming an indoor event with ISO100 and needed to bump up the shutter to get the right exposure at f1.8. And outdoor at night I was filming at ISO400 easily. The biggest drawback with this combination is getting a stable grip as you are holding the lens more than the camera, as the a5100 is quite the small camera.

Here are some screen grabs of the footages shot with this camera.
