For your info:

1. You could up the shutter speed or lower the ISO or find shade to shoot in.

2. Dunno cause don't have NEX cam.

3. Small f number = easier to get bokeh but no guarantees that bokeh will be nice. Different lens give different bokeh. When using telephoto lens, the tele effect also makes it easier to get bokeh. Depending on the distance of lens to subject and subject to background the bokeh will be different. The more tele, the better the bokeh generally.

4. EXIF data can be seen when you right click your pic and choose properties and there is a button in there that will display the info. You could do a screen capture from that page and post it if you do not want to type it out. Basically don't get too hung up on EXIF data. It's much better to spend your time understanding how ISO, aperture and shutter speed work together to give you the exposure you want rather than digging up the EXIF info on every pic you see. I've said it a hundred times but I'll say it again - EXIF data are only good for troubleshooting some issues. They are not much help otherwise.

Just my 2 cents.
