Hi,

FredBG pointed me to Rhinocam by Fotodiox. It may be that this is a solution for us having MF lenses but not waging the jump to a Phase One back?

The idea is smart...

Best regards

I've just bought one at their (Fotodiox) current discount offering, which includes all three (Mamiya, Pentax and Hasselblad) medium format lens adapters.  I did so based on my good previous experience with the Fotodiox lens shift adapter for use with 35mm film lenses with m4/3 cameras.  Both these adapters take advantage of the larger image circles of their lenses vis a vis the sensor size of the cameras they're mounted on.  As I do not yet own a medium format lens, I am waiting to try this adapter when the used lens I have ordered from KEH arrives later this week.  I have ordered a Hasselblad because its image circle is a bit larger than the image circles of the Mamiya and Pentax 645 cameras.

One "creative" aspect I perceive for this new adapter, which hasn't been mentioned yet to my knowledge in the advertising and other forum discussions of this adapter, is that is it is equivalent in concept to a mosaic with eight tiles.  As such, each tile can be photographed a number of times to include a possibly changing (moving) aspect within its frame to modify somewhat the basic restrictions of this adapter to primarily static images.  In the PP stitching process, the preferred multi-image tile can then be chosen for inclusion in the final picture.

I can't wait to try this out when my lens arrives.

Finally got a chance today for my first test of my RhinoCam with my newly arrived used Hasselblad-V 80mm lens (after the clouds lifted a bit here in Seattle) mounted on my NEX 5n.  I photographed the house and lawn across the street.  (No photo attached.)  I took a similar picture with my somewhat equivalent 28mm Nikon (35mm film) lens mounted on my Sigma D15 DSLR.  As I had lots of previous experience with the Fotodiox shift adapter for my m4/3 Panasonic Lumix (with 35mm film lens), the principle and operation of the RhinoCam were not entirely foreign to me.  Anyway, as was to be expected, the definition of the stitched RhinoCam image was far sharper in detail than the DSLR image, but in other regards color was comparable.  However, I process most all my images with DxO, which may be the primary reason for the color compatibility.  Anyway, much more experimentation must occur, but so far I'm quite satisfied with this brief, initial trial of the RhinoCam.   One initially experienced disparity was that I seemed to need to focus the picture on the LCD of the attached NEX, as the focus distance markings on the Hasselblad lens themselves didn't match up.  Of course, I need to investigate this apparent disparity further.

I would not expect the flange to medium distances to match. However can you focus on something that is effectively at infinity?

Ellis:  I've performed further testing, and images focused on distant (infinity) objects on the camera's LCD, and which reproduced sharply on the monitor when processing, in every instance had a flange marking (setting) of 15-feet.  I've queried Fotodiox as to whether this disparity hasn't something to do with the (faulty?) manufacture of their Rhinocam adapter for Hasselblad lenses.  i haven't heard back yet.  While I can take photos all right with the adapter as is, it renders inaccurate the flange's depth-of-field indicator for various apertures.  Jim
