Hi. This is my first post. I got my D50 in August. I got it at Costco and it came with 2 lenses: AF 28-80 mm f/3.3-5.6G and Af 70-300mm f/4-5.6G. I have purchased a Nikkor 50mm f/1.8D and a Tamron SPAF 90 mm f/2.8 DI macro 1:0, AND I have on the way a Tamron 200-500MM. I think I need/want 1 more lens. A wide angle. There are too many choices out there. I would like some feedback as to what a lot of you consider the best for the wide angle/landscape lens to purchase. I've spent a ton already, so it doesn't have to be the very best, but good. Thanks for any assistance. Julie
There are a lot of choices and all have their strengths and weaknesses.
The Nikkor 12-24 f/4 is probably the best of the bunch, but not by a lot, and since it costs twice what the competitors cost, many (including me) have questioned whether it's twice as good.
The Tokina 12-24 f/4 has the same range and speed of the Nikkor. Reviews say it's very sharp, built like a tank, but shows lots of color fringing.
The Sigma 10-20 f/4.0-5.6 is not as fast at the Tokina or Nikkor, but it's the widest of them all. I love this lens but it might not be the choice for you since your wide only goes to 28mm, you'll have a pretty important gap from 20-28mm. You're probably better served by one of the 12-24's, or consider switching your mid-range zoom to the 18-70.
The Tamron doesn't seem to rate much and is probably an also-ran in this category.
I just purchased the Tokina 12-24 this Saturday and had a chance to try a few shots. I love it!
There is a bit of CA at wide open and widest settings but nothing objectionable. Easily removed in PP. The lens stopped down to f8-f16 is very sharp, and the build quality is better than my Nikor 18-70.
