or should it be free lensing? I've seen it written both ways and it bothers me that I don't know which is correct.
Years and years ago, the thought of a using a tilt-shift lens didn't really interest me. Possibly my accountant side was a bit turned off by the results. In the past year or so, I've tried to branch out and explore other areas of photography and tilt-shift has become more appealing to me. (Never say never.) But I have a whole bunch of lenses on my wish list and it takes me a long time to really decide what I'm going to purchase. I research, and then research some more, and then explore other options. Over the summer, on instagram, I noticed other photographers freelensing, which gives you a tilt-shift with the added bonus of not having to purchase a tilt-shift lens.
If you're interested in freelensing, I recommend this tutorial. It was the only one I found as a Nikon user that really explained in detail what needed to be done with my lens before I could freelens. If you have no idea what freelensing is, you are basically taking a photo without your lens attached to the camera. The tutorial that I linked to was super helpful as well because I have the same 85mm lens.
I don't freelens very often (rarely actually) because I'm not a fan of exposing the inside of my camera to dust and other particles, but I do like the results and keep moving a tilt-shift lens up on my wish list.
As you all know, I mostly take photos of my kids. Of all the photos I've posts on instagram, this has been the only one featured. Ironic.
