I am looking to add 1 more lens to my collection (if 2 is a collection). Currently i have a 35mm 1.8 and a 50mm 1.8. I am looking to do more portraits (half and full body). I was looking at the 85mm 1.8 but a lot of people say it will be too close to the 50mm. I am also looking at telephoto lenses. I would like to keep the price down get get the best IQ for my money. I have a D90 BTW. Any help would be great. Thanks
