the lens is large enough for the movements that are built into the graflex.
Ian, all that you wrote is true, except for the unstated assumption that movements -- decentering, tilts -- are possible with Graphics.The 135mm Xenar has no room for movements and won't give good overall sharpness until stopped down to f22, wider open the corners and edges go soft very quickly - great for portraits. Even slight rise will cause vignetted corers, a 150mm Xenar or Tessar is only a little better.
Used carefully Xenars & Tessars are quite capable lenses but be aware of the restrictions, any tilt must be compensated for with rise or fall to prevent vignetting.

Hi,
Speed and Crown Graphics will take a fairly wide variety of lenses. The wider ones will be harder to use with movements, due to he fact that you just cannot get your fingers in there to turn the knobs and such.
Large format cameras don't really have proprietary lens mounts; they just have proprietary lens boards, onto which you can attach whatever lens you can manage to rig up.
So, the limiting factors are whether or not the lens board will be able to physically take the lens, and whether or not the bellows can stretch long enough or compress short enough to properly focus the lens.
Speeds and Crowns have small lens boards compared to many large format cameras, so the size of the shutter and rear cells is something that should always be measured or test fit first, before buying a lens. Generally, the widest lens a Crown can take is a 65mm, while Speeds have trouble with anything much shorter than 90mm (and I even find 90mm a bit awkward). This is because the Speed has a rear shutter that gets in the way of the wider lenses. I think (and you need to check Graflex dot org to make sure) that both cameras can take a 15 in. lens (nearly 400mm), and maybe a bit longer.
The rangefinder can be calibrated for lenses within a certain range, but I forgot what the range is. Check Graflex dot org. They will have that information, and instructions for doing the calibration. But, to tell you the truth, I'd just leave it be so you can use the 135 hand held without movements, and use the ground glass for the other lenses with movements.
It is good that you got one with a Graflok back. The cameras are much more limited without this back.

They allow front rise, which is useful, but not much. Front fall, no, except in very special circumstances. Lateral shift? Well, in principle yes but in practice usually not except with lenses so long that when focused the front standard is in front of the bed struts. When the front standard is between the struts they pretty well prevent shift.
Tilts? The bed drops and the front standard tilts backwards. At first glance, combining the two will give forward tilt and front fall (drop bed, tilt standard all the way back, it will then be vertical). Neither works for lenses that focus where desired when inside the box. Otherwise, its catch as catch can. Sometimes everything -- focal length, focused distance, fall or tilt desired -- is in alignment and the desired effect can be obtained. This rarely happens for me.
These cameras are for shooting straight ahead or with a little front rise to eliminate the foreground/avoid (if lucky) converging verticals. They're press cameras, and very useful, not proper view or technical cameras.
esPhotos, much as you want it, in LF its hard to avoid the technical stuff. I take it that you come to your Graphic, as I did to mine, from 35 mm. There's a big difference. Learning what it entails for, um, what one should know takes a while.
2f, the board isn't a constraint and neither is the front standard's throat. If you think about it, you'll see why the board is irrelevant. The front standard can be a problem. I have a couple of w/a lenses (35/4.5 Apo Grandagon, 58/5.6 Grandagon) whose rear cells are too wide to pass through my little Century Graphic's front standard. No problem. Unscrew rear cell from shutter, attach shutter and front cell to front standard, pass rear cell through the gate, screw back into shutter. Fiddly, possible, and I do it.
2f, flange-to-film distance, not the focal plane shutter, is what limits the use of short lenses on Speed Graphics. Again, think about it and you'll see why. The shutter is very close to the film plane. You probably meant to say that a Speed is thicker, i.e., has longer flange-to-film distance, than the equivalent Crown because of the focal plane shutter.
I certainly cannot mount my old Voigtländer Petzval copy on my Speed, even though it is only about 240mm. It is just too fat.
Great info guys.
The main reason that Ive chosen the Crown is its light weight that suits well for long hiking. Movement is not entirely necessary, I think, as I am use to smaller formats. But if I ever needed, I now know that there are lenses to adapt.
cheers
esPhoto, you are trying too hard to do the best thing. There's a law of nature to the effect that the first 4x5 camera is always the wrong 4x5 camera, regardless of what it is. Just get a Crown and use it.
After a while you'll learn what you really need to do that it can't and which aspects of using it really bother you. Then you'll be better prepared to look for a 4x5 camera that suits you. And if you don't pay too much for the Crown you should be able to sell it at no or only a small loss.
What would be the going price of a reasonably clean Crown ?
Checked the bay and they go for around $400.
