Good day!
A hobbyist here and I'm getting a chance to buy my next lens.
I only have kit lens(18-55) for my D5000 and I'm looking for an upgrade.
What I'm looking for right now is good for landscape and portraits..
Large Maximum appertures and can produce sharp images.. All-around lens in short.. I currently have my Eyes on Tamron 17-50mm 2.8, 28-75mm and 18-270mm (Yes they are all tammys

)
Are these lens sharp Compared to the nikon's kit lens?
Do they even fit and AF on my D5000?
Do you know any other lenses you can suggest?
