I am a novice and I'm looking to expand my lens collection (I only have the kit 18-55 at the moment) mostly for use while traveling. I am probably going to buy the 55-210 zoom as I sometimes need a longer zoom (especially for wildlife) and feel it is the natural supplement to the kit lens. Between the two I will have a large range covered and should get a good sense of what lengths I am shooting most. I would also like to get at least one lens that is smaller and faster. I am trying to decide between buying the Sigma 2 lens set or the Sony 35/1.8. I know the Sony is a faster lens plus has the benefit of OSS, but I wonder if it will be that much better than the Sigma 30mm at more than twice the price of the 30 and 19 combo. I want to use it both for situations when I just want a smaller setup and also for indoor situations (museums, restaurants, etc.). Do you think I'll be happier if I spend the extra money now, or might I be better off trying the Sigma first and see if it is sufficient? For what it's worth, until I bought the F3 I was using a Canon S90, which has a 2.0 lens at its widest, but a much smaller sensor, so I was more limited in terms of increasing ISO if I wanted reasonable IQ.
