Hi all! I have a Nikon D3000 and currently have the following lenses: - Kit lens (Nikon 18-55mm f/3.5-5.6G AF-S DX) - Wide angle lens (Sigma 10-20 mm) I'm looking for a lens to complement these. I LOVE my wide angle Sigma, but only use it for landscape and architecture photography. So I've been using the kit lens for almost everything, and I'm looking for a higher quality "walk-around" lens to replace it. What I'm looking for, in order of importance: 1) Easy to achieve bokeh - I do a lot of close-up portraits where I prefer a small depth of field. 2) Good/decent performance in low light - I live in a very cloudy rainy place 3) Versatile enough to be used for group photos and landscapes on occasion 4) Not too big and bulky - I travel a lot, so I prefer shorter lenses Looking to spend ~$300 or less. So far, I am leaning towards the Sigma 50mm f/1.4 EX DG HSM. Is this my best option? If not, what would you suggest? (I was also looking at the Sigma 18-250mm f3.5-6.3 DC MACRO, but I figured that the 50mm prime lens would give me better bokeh and a less bulky lens) Thoughts? Thanks!
