I was asked a while back about what Camera I use and I'm so so sorry that i'm just posting this now!
I use a Pentax Ist DS and I bought it from around £150 from a second hand camera shop in my uni town. I absolutely love my camera, it's almost like my child to be quite honest. I find the quality to be wonderful, the only downfall to it would be that it uses batteries rather than being rechargeable!
I love the way my images come out, I can get crisp sharp photos of impeccable quality, or I can get the slightly grainy old looking images that i love so much. I know generally in the fashion blogger world the most expensive Canon's and Nikon's are considered holy grails but to be honest in my opinion it's all up to your skill as a photographer rather than how expensive your camera is.
Hope this has helped! Any more questions hit me up on here or my twitter or my tumblr!
