I cba to shoot in RAW (NEF on my camera, I believe) because I upload my JPGs online a lot, and it's effort converting them. Also, I'll probably have to adjust the lighting etc. on every photo as the camera won't do it if I use NEF.
I do believe I told you to use either A or S and maybe M down the road when you get comfortable though.
As fora new lens, as I said before, lenses with very large aperture will give a very shallow depth of field.
But you probably need to bump past a 1600 ISP to get fast enough shots at night. I suggest you simply take the camera and have fun and play around at night a few days, and use the camera screen to check brightness and motion blur so you know what settings cause what.
And as I said I the other thread, if you shoot to dark, as long as you use raw, you can bump the exposure 2 levels without losing details. Lightroom can also remove a lot of the iso Boise at the cost of smoothing out details.
I'm willing to put effort in, hence this topic, but not that much every time I put photos onto my PC and wish to upload them.
