I'm new to stitching. I've done a little research and I think a Nodal Ninja head would suit me as they are relatively compact, lightweight and affordable. I just need some help in choosing the right head.

Objective: To use a Nikon D700 to shoot high resolution images to match the quality of the best medium format backs (e.g. P65) or scanned 4"x5" film.

Subject Matter: Urban Landscape, Architecture, Interiors

Aspect Ratio of final image: 4:5 or 2:3. (I'm not interested in panoramas)

Focal length: The final stitched image will have a wideangle field of view, somewhere between 20mm and 35mm on a single 35 frame. (Nothing ultra-wide)

Current equipment: Nikon D700, Manfrotto tripod, Manfrotto 3 way head, Nikon manual focus primes (20, 24, 28, 35, 50, 85). I intend to use one of the wide angle lenses to create a master, single-frame reference shot, and then the 50 or 85 to create a spherical stitch (I think that's the word (?) - 2 or more rows, with the camera vertical).

Software: I'm looking at Autopano Pro and PTGui. I'm on a mac.

Quick Release: In general I like to use QR plates for speed of operation. I juggle between the Manfrotto system (rectangular plates) and Kirk (arca style).

I hope this is enough info for some advice.

Thanks in advance.
