Re: Lens suggestion for speakers at conferences

Two days ago I used my new Sigma 50-100 the first time during a talk.

I was quite happy with the lens. The venue was not really large (about 50 participants). If audience is larger, more focal length on both sides would be nice (e.g. a 70-200 on FF).

In this case I was happy with my FL of 50-100 and also the aperture. The venue was brightly lit. All the more, I was surprised about the ISO needed (mostly 500-1000) to get a shutter speed of 1/125 and shorter. I think noise is starting to be visible on 100% crops above ISO 640. Above ISO 1000 it is distracting.

The handling of the sigma is great. I like the smooth zoom ring. The weight is okay. I sometimes used my monopod, sometimes I hold it freehand. Freehand is working if you don't have to shoot the whole day.

What I found out: I need to be more accustomed to my gear. I tried P, Av, and M with and without Auto ISO. I used continuous and AI servo. The mid autofocus point (with recomposing) and dedicated autofocus points. But I definitely need more practice. I had too few keepers due making mistakes with my camera.... And whitebalance was quite off, when set to manual. I had to adapt it in post.

Here are some of my best shots. RAW, post processed (Exposure, sharpness & noise with DXO Optics Pro):

What do you think? Any tipps for improvement?
