Peter The only thing I wonder about with adapting larger lenses, is obscuring the viewfinder window. It should be possible, though obviously some machining involved. It is a little surprising that there are not more adapters to fit lenses to the XPan. I'd thought I'd just use an add on finder anyway for any of this - a 6x7 one marked down would work fine, or I could build something with wire. I don't see using the rangefinder - an adapter could be built that would couple, but it would be very lens specific, and of value only with wider lenses where the RF would have a hope of giving accurate focus. Guess focusing by distance scales on the lens would work okay most of the time with a super wide on the XPan. The combination would be much cheaper than the XPan 30 mm lens. Got one of them :-) Very nice it is too - bought it, along with the rest of the X-Pan kit, with some money left me by my grandmother, who _many_ years before gave me my first SLR. I think she'd approve. It has really surprised me that no one is making adapters for the X-Pan, I wonder if there is patent protection still in force for the mount. The one I saw a few months ago looked home built. Almost any place with a CNC could probably make up adapters easily, though a volume order would be better to drop costs; of course that brings a question of whether there is any market for adapters. There seems a steady market for adapters to put P6 lenses onto most 645 bodies, and (which I understand a little less well) most 35mm mounts too. I'm sure I'm not the only X-Pan owner who'd like the idea of shift lenses, glass longer than 90mm, faster glass, and/or that fisheye... If I was sure there'd be no problem with a patent on the mount (ie., if I had time to research it) I'd order up a batch of ten or twenty X-Pan to T-Mount adapters or something similar (so they could be given any front end) and sell the rest on *Bay. The lenses I'd like to use would be my shift ones (very tricky to compose though!) and more particularly to use something longer than the X-Pan's 90mm. Shift lens could be covered by an ALPA type of finder, in which lines for shift distance are etched into the finder. While the ALPA finders are very expensive, modifying another finder type might not be too tough. Silvestri et al use a tilting finder to deal with shift: shouldn't be too hard to build something like that. Of course, even more fun would be being able to use tilt for vertical panoramas - but that's definitely a bridge too far for the X-Pan (for me at least). I'll still go to MF (and LF) for that. There was a rumour of Fuji/'blad bringing out a 135mm for it at one time, but they never did. I'd love to use my Zeiss 120 and 180mm, and Schneider 150mm on the X- Pan. I'd cheerfully carry along the 150 (and some sort of finder) to use on the X-Pan on occasions when I didn't have an MF body with me. I have a feeling that the lessons of Bronica with the 135 mm for the RF, and some focusing problem reports with the longest Mamiya 7 lenses, might have caused them to think twice about offering something. Good point, the Bronica debacle would be enough to scare anyone off. If they added a viewfinder magnifier similar to what Leica have introduced, then longer lenses should be possible with accurate focusing. Scale focusing longer lenses would eventually cause some error. Yes, a magnifier would be a very nice, simple, solution. Wonder why not... And then there's the 30mm fisheye, come to think of it! Oh well, I can dream (don't think I can afford to hire a machinist to do the job...) Peter Around here, machinists are still $50 to $75 an hour. Unfortunately, a bayonet mount is not that quick an operation for manual or DRO milling. A CNC would be better, but the set-up costs are high. They charge more here, and as you say, a bayonet takes some time. I think the best would be to get the XPan bayonet, then cut it and resection it to take a different mount. A metal body cap could provide one source, or a broken lens could be another, though perhaps not common enough pieces. Alas the body caps are plastic. I suppose I could experiment with one just to see how rigid it is: it would wear out in use, but maybe be cheap enough to regard as a consumable. Broken X-Pan lenses seem to be rarer than hens' teeth. Peter |

Not something I know about - is that Nikon specific, if not where can I find more? (Or should I just do a search on the name?) Nikon specific.

.net... If you have the Nikon 8000/9000, it's just large enough to do 6x17 in two scans. Film flatness is a bear, though, so if you've got the ventilation, the Kami-fluid carrier sounds extremely attractive. You can also use flatbeds a number of current flatbeds. While initially the scans are not as sharp as the Nikon's, very acceptable scans can be achieved with the right post processing skills and you can scan a 6x17 in one pass. Canon and Microtek now have some decent 6x17 holders standard with their higher end models. Thanks for that thought. I use my old flat bed to do low res. scans of 4x5 (I have to send it out for really good scans, but this is OK for making thumbnails and images to email). Unfortunatley the transparency hood for it isn't long enough to cover a 6x17, so I think I'm stuck with the two pass approach in my Minolta scanner for now. Still, it's something to bear in mind when/if I replace my flatbed, since it isn't going to last forever. Doug -- Doug's "MF Film Holder" for batch scanning "strips" of 120/220 medium format film: http://home.earthlink.net/~dougfishe...mainintro.html Hmmm - I've archived the link so that if I ever get a better flatbed I can go back to that. Thanks. Peter |

I think she'd approve. My grandmother encouraged my painting skills, and is one reason I finally got an art degree. I think if she were still alive, she would be happy at some of the achievements I have made.

I'm sure I'm not the only X-Pan owner who'd like the idea of shift lenses, glass longer than 90mm, faster glass, and/or that fisheye... I know a CNC programmer who would jump at the job, though of course the issue of patents needs to be solved. Perhaps Hasselblad could be encouraged to allow a short run to test the concept. If I was sure there'd be no problem with a patent on the mount (ie., if I had time to research it) I'd order up a batch of ten or twenty X-Pan to T-Mount adapters or something similar (so they could be given any front end) and sell the rest on *Bay. I am not so sure about T-mount adapters. The Xpan lenses are basically a 645 style of construction, though the size makes a few other choices possible. Current Hasselblad SLR lenses might be one direction. A Nikon mount, considering how many manual focus lenses they have on the market (new & used), is another consideration, and that would allow using other adapters. A Leica M mount would unfortunately not work due to the too short mount to film distance. The lenses I'd like to use would be my shift ones (very tricky to compose though!) and more particularly to use something longer than the X-Pan's 90mm. Shift lens could be covered by an ALPA type of finder, in which lines for shift distance are etched into the finder. While the ALPA finders are very expensive, modifying another finder type might not be too tough. Silvestri et al use a tilting finder to deal with shift: shouldn't be too hard to build something like that. I have looked at their design. I think it would be complicated to graft onto an existing camera, though I agree that it is a nice solution. Of course, even more fun would be being able to use tilt for vertical panoramas - but that's definitely a bridge too far for the X-Pan (for me at least). I'll still go to MF (and LF) for that. Consider something like a Nikkor 35 mm Shift lens has a view angle like a cropped 21 mm (approx.). Using a 21 mm finder, and etching lines to show changes of shift amount, would work nicely. Any shift lens with marked shift distance could use that type of solution. The medium format shift lenses might be a better choice due to greater coverage. There was a rumour of Fuji/'blad bringing out a 135mm for it at one time, but they never did. I'd love to use my Zeiss 120 and 180mm, and Schneider 150mm on the X- Pan.

Good point, the Bronica debacle would be enough to scare anyone off. I still like the RF645, and think it is a wonderfully ergonomic design. Unfortunately, it seems that Tamron will not put any more development into it. If they added a viewfinder magnifier similar to what Leica have introduced, then longer lenses should be possible with accurate focusing. Scale focusing longer lenses would eventually cause some error. Yes, a magnifier would be a very nice, simple, solution. Wonder why not... Sales might not be good enough currently to entice Hasselblad to manufacture something. This is another thing that a third party company might be able to produce in small quantities, if permission is given by Hasselblad. And then there's the 30mm fisheye, come to think of it!

They charge more here, and as you say, a bayonet takes some time. I am still working on my project camera, though it is going slowly. I have a couple different shutters now, but a few details still need to be worked out. I am leaning towards doing a 6x6 version to allow some shift, and make it more like an SWC.

I would not trust a plastic mount with any lenses, even though some companies sell cameras and lenses like that currently. Ciao! Gordon Moat A G Studio http://www.allgstudio.com |
