Nah. I want MOVEMENTS! Shift, shimmy, and tilt! I want to shoot landscapes with "infinite" depth of field (tilt), cliff faces (rise), local architecture (all sorts of movements). This is a bucket list thing. I might hate it after a year of putzing with it. I might be seriously hooked - a 30 x 40" print from a first-rate 4 x 5 color transparency is an awesome thing, and I have always liked analog B and W DIY.
That's how it starts, I've now got two 4x5 monorails (with 6x7, 6x9, 6x17, and 70mm roll-backs), an 8x10, two 4x5 Travelwides on their way, plus a whole bucketload of lenses, 65/90/135/180/270/465/600, and my latest (and oldest) addition, a 12"/21"/28" Turner Reich Triple Convertible uncoated Anastigmat. Hey, if it was good enough for Ansell Adams it's good enough for me (and this entire setup still costs less than a 5D3+lens kit).
But after a year or two of scanning film (epson v750), all I can say is, get an enlarger. But an 8x10 enlarger is huge, so all of my 4x5s, 6x17s and 8x10 are contact-printed with my 6x7 colour-head.
BTW, www.apug.org is where all of us film weirdos hang out, if you start there you'll really learn what GAS can be...
