I've been toying with the idea of having a go at large format photography for many years, but now I think I have the resources to cope with it. I know some on here have substantial experience with LF stuff (I know David Martin does for sure), so I'm hoping for a few pointers.
Initially I fancy 5x4, because its comparatively handy, and lenses for the type fo thing I am interested in are moderate prices. I should point out that what I am interested in is landscapes, and some architectural photography. I have considered buying a secondhand (I suppose someone must buy new LF stuff, but I have no intention of doing so!) 5x4 field camera, possibly a Toyo or Wista. A lens such as a Schneider Super Angulon 90/f8 or maybe 6.8 seesm reasonable, and there seem to be loads of them out there.
However.... I do fancy building my own camera, and whilst its quite an undertaking, I do have some engineering skills and the equipment (lathe, milling machine, friends with laser cutters and CNC mills). This opens up the format question again. I do lust after a 6x17 panoramic camera, and this could be achieved with a roll film back on a 5x7 field camera. Obviously building or buying a 6x17 back is a major undertaking, but what the hell, it can't be harder than an articulated live steam locomotive.... Obvously I'd buy sheet film backs, darkslides etc, and would intend to tank develop the resultant monochrome sheets, and then scan them. I could actually scan 6x17 on my present scanner, but 5x4 would need me to cough up for an Epson V700 or 750...
I have past experience in medium format, with a pair of Mamiya C33s, quite a few years ago, but I've always had a hankering for landscapes done very calmly and slowly in 5x4 or thereabouts.
Its no good me asking you lot if I'm crackers, I know I am, but is there some sense in my train of thought, and should I be looking anywhere specific for secondhand field cameras, other than Ebay? Embarrassingly, I've never actually even seen a 5x4 camera up close, and I'm fairly sure than none of you that have such things are anywhere near me, I believe David Martin is at the other end of the land mass in question...
