I am going to Dragoncon (a sci-fi convention) this weekend and am unsure of what lens to bring. Of course I would love to only have to bring one lens, but I know that taking pictures can be hard at conventions. Sometimes subjects are really close, sometimes they're super far away, and more often than not- the lighting conditions are not what you expected. I still consider myself a little bit farther along than a beginner but not an advanced user, and most of my lenses were acquired as gifts. I've only ever bought one lens- the 18-55 that came with my kit. That said, I'm unsure of which of the lenses I have would be best to bring? I've narrowed it down to these two:
- Pentax DA 40mm F2.8mm XS Lens
- Sigma 18-200mm f/3.5-6.3 DC Lens
I really love the 40mm/2.8 and use it almost exclusively, but I am worried about moving around to much to get the right focus in a convention hall. Is this a right concern? It's the fastest lens I have for when it can get quite dark. My Sigma is not as sharp as the DA and I can look at my pictures and instantly tell which photos were taken with the Sigma, but it also has that range.
Thanks for your help!
