I have been looking at a lens that would be suitable for taking out when you only want to take one lens and noticed the Sigma 50mm - 150mm and wondering if any one has it and how they find it. (For Nikon D5000 still considering the D610). I know size wise it's about the same but it is about 500g's lighter and at 50mm rather than 120mm at the lower end is a better range I think
I did try the 85mm f/1.4 Nikon and was very surprised at the low price over the counter without even asking for their best price so that is definitely on the list. $600's lower in price from the first shop where I actually tried a couple of shots with it. So at this stage I may not even try the grey market.
