That's correct, it's a question of geometry. Therefore those who buy cameras with extreme wide angle lenses capabilities should check if the camera has more to allow them than just bag bellows...:)Quote:

The 2" lens moves less far for a given change in focus. Thus, focus precision must therefore be greater for shorter lenses.Quote:

If the camera is three feet off the ground, the tilt for a 2" will have an angle of 2/36 (expressed as a gradient for clarity). That 2" lens on a 4x5 camera does the same thing as a 4" lens on 8x10. The 4" lens will have to be tilted at an angle of 4/36. So, for the same effect on the focus plane, a short lens needs more precision in tilts and swings than a long lens. And 8x10 cameras are easier to use without precision movements than 4x5 or medium-format cameras.

... and from reading posts in here for a couple of years it seems, that most of you like separate controls for rise and tilt - or at least zero detents for tilts, when using rise/fall... why not the same for swing and shift then? same thing, different axis...
I think the reason is a mechanical one. While doing tilts you need to hold the rise value with your hand in the non separate version of cameras. But making swings does not disturb the shift in the same way - the slight difference is perhaps the answer.Quote:

Does this take Sinar sized bellows?
I'm guessing that they already do!Quote:

I'm certain that there are a load of guys that surpass the Dusseldorf school photographers (Hoefer, Ruff, Struth et al) but because we can't read the abstracts about their bodies of work, we just think that they are boring snapshots :D
(This is only a joke. I love contemporary fine art)
The camera looks great BTW.

Hi Myoptic:
I didn't want to reply on this topic before, but I really don't think most foreigners understand China and Chinese well.
It is very difficult for Chinese people use their ability to its full potential, although China has a big population.
If u have a chance to live in China for a long time, pls pay attention to our bureaucracy, average salary level , real estate price, price level , education system, law system,etc.. U will get the answer.
I convince that, if our system become more healthy(I wish), we will produce giants in many aeras.
tks
Hugo Zhang tells me that Chamonix has sold several thousand 4x5's in the domestic Chinese market. They are selling large format cameras at a quicker pace than Deardorff ever did.
Now it is true that for generations many/most of all still and video cameras were made in Japan, a huge percentage was sold there, and less great art (and particularly film/video) has come from there than you might expect.
But my bet is on the Chinese to amaze us... and hopefully keep the world producing large format film.
