I am brand new to this site and just got into photography the past 2 to 3 months. Ive been taking a bunch of pictures and editing them and i feel as though my sharpness or quality isnt as i guess you can say as good as i would hope. I currently shoot with a NIKKOR 18-55mm f/3.5-5.6G VR II and a Sigma 10-20mm f/4-5.6 EX DC HSM with a NIkon D3300 body.
Now i was wondering to get a better sharper picture would it be best to think about upgrading lens or think about possible getting a higher end camera possibly a full frame. Which of these would get the best results, spending 2,000 on a new camera or maybe getting better lenes? I primary shoot Landscape photos and i notice the sharpness issues when it comes to the trees in the background.
If the lens may be a better bet are there any suggestions as to what top nikon lens would be when it comes to getting a clearer sharper picture?
Thank you so much for your time and im sorry for the beginner question.
