This sounds very interesting. It seems to be a lens that some people love, others loathe. There also seems to be a 24/1.8. > I am thinking that anything else starts at f/2.8.

I hadn't realized that there was a DA 14/2.8 until I started poking around today. I thought that they were 4.0, but looking at my shots from the pdml gathering I guess that it was a 15mm. > If you want a single lens solution then Sigma 17-70 is an option. > Thanks to Jaume I had a chance of using it and mechanically it is ok. > Given the darkness outdoors I cannot say too much about its optical > performance though it seemed ok. It may not be as fast as I like at the long end, but I'm mostly looking for speed at the wide end, as I have primes for 30 on up.

It seems that the wealth of possibilities may spare my pocketbook just through the mechanism of indecision. Last year at Dickens Fair (which starts again next weekend), I was thinking about the lens I needed for it, and pretty much came up with 16-50 f/2.8, without knowing that the lens already existed. -- The first step is learning to take great photos, the second step is learning to throw away ones that are merely good.
