I am puzzled at the moment, I stalking around the internet for information off a good border to border performance lens with a bit reach. The two lenses that I checked out seems to be a good performancers on the paper. But the sigma even to be said be a nice lens when not used in macro shots. The shoots I want to pixelpeep is landscape and architecture shoots. Especially architecture shoots it is almost more important with nice contrast then plain resolution. The nikkor 180mm is in nice pricerange. I also been happy with my two other primes. My type off photos I rarely shoot with shallow Depth of field. I guess 75% of my shoots is above F/stop F8.0. Which the reviewers often mostly show off nature or sport shoots. Which mostly use a quite shallow depth of field. I just use OOF blur as effect which is rarely. Humans are my most rare subject. Which my 35mm has become my social lens. I am a tripod user, I setup the camera. Move around alot, wait alot for the right light. If you have 1000 dollar budget which lens would you believe make me happy? I checked out the 70-200 mm zoom but it is a bit to much money for a reach I rarely use. I think I will probaly get best border to border perfomance per dollar with a prime lens. I am quite new to photography. But I would like to say that I am dedicated amateur that like good performance.
