Pentax only made one shift lens (for 35mm), the "K" series 28mm shift. It goes for between 300 and 600 pounds on ebay depending on condition. There is also a shift lens for the 6x7. Unfortunately, a 28mm shift on a APS-C sized sensor is not all that useful (but I'd still like one).

Canon and Nikon do indeed make tilt and shift lenses with the Canon 18mm TS lens being really very nice but costing well over three grand.

The Hartblei ones are difficult to get hold of (although they do come in K mount) but are not all that wide.

The alternative is a large format view camera. These can be got surprisingly cheaply on ebay provided you do not have your heart set on a Sinar. The Horseman LE which I have usually goes for about 300 to 400 pounds to which you have to add lenses and lensboards, bellows (both normal and bag), a very sturdy tripod, darkslides and a hand held lightmeter.

The large format world tends to be a little more formal how it describes the movements. "Shift" is when the front or back element of the camera (i.e., the lens or the film) is moved from side to side; "rise" and "fall" is used when the movement is up or down; "swing" is used when one element is set at an angle to the other from side to side (e.g., when the right hand side of the lensboard is nearer to the film plane than the left) and tilt when the angle is top and bottom.

HTH Kris.

Snow normally causes under exposure not over due to the meter trying to render white as 18% gray.

Best wishes, K.

I think most people think it is worth it so that you have full functionality of the lens. With the PK mount you can, essentially, only use the lens in manual.

I'm sure Mike will advise.

Best wishes, Kris.

I am very fond of my ES so I am sure you'll have fun with the ESII.

Taken yesterday. K.

Sounds like me trying to decide what kit to take when I go for a walk...

'More desirable' is almost always the more unusual variants. In the case of the ES/ESII most were black, the chrome versions are much rarer.

Well you won't miss one or two with the cupoboard full you have, would you? That FA31 is a bit old fashioned now, isn't it? And you don't really need that DA* 50-135...

Christmas wishes to all. May your images be sharp, your colours glorious and your subjects fascinating.

Kris.
