I own a real estate management company. We currently provide tenants and owners with a set of images of the condition of our rental properties on a DVD. People like it because they feel they have a true record of the condition which is much better than a checklist. The images show sections of walls or inside cupboards and draws they are not real estate marketing images.
I am currently using a hand held Nikon D5200 with an AF-S Nikkor 18-55mm f/3.5-5.6 lens, mostly shooting at 18mm f/3.5 and ISO 250.
For light, I have two professional standard units. One on the camera and one remote unit.
I would like to shoot at as lower ISO as possible to reduce granularity when the images are blown up on a screen. I have been looking at getting a Sigma 18-35mm f/1.8 lens. Would I do better with a full frame camera?
Before I do make any new purchase, has someone tried something like this? Do you have any suggestions about equipment and/or techniques?
