Getting Acclimated with my 24-70

After getting off of work yesterday, I wandered around midtown (up to Grand Central Station, then down to 23rd Street) I took some pics to get acclimated to my new (used) 24-70 lens. Safe to say, I'm satisfied with the quality.

A little bit soft on the focus but the quality of the shots are really nice! :)

I had to use wider aperture (2.8 - 9.0) and ISO 250-1000 in most scenes due to the low light conditions. I did not lug my tripod with me yesterday, but I am planning on doing long exposures in NYC to when it gets cooler out.

Hi Paul,

Why don't you use a higher ISO and narrower aperture then?

Anything between 13-16 would have been underexposed and probably most of the images would have turned out blurry. The tall buildings in the city blocks a lot of the sunlight when the sun is setting in the evening.

Hi Paul,

Then why not use F11? (by the way, if you're in Av mode it should never under-expose - so it's really just a case of not letting the shutterspeed drop to a point where camera shake enters into the equasion (thus increasing the ISO)).
