This new lens from Samyang may provide a cheap entry into the PC range. http://photorumors.com/2012/09/02/first-image-of-the-upcoming-samyang-24mm-f3-5-tilt-shift-lens/ Need to wait until after Photokina to see if it arrives and at what price.

I have the Nikon 35mm f/2.8 PC Lens 1, which I don't use much for perspective control shots anymore as they aren't as useful on the smaller sensors. Mine looks exactly like the B&H one. http://www.bhphotovideo.com/c/product/800882482-USE/Nikon_35mm_f_2_8_PC_Lens.html It rotates on the mount with click stops every 30 Degrees. There are white dots showing on the B&H pic. The Samyang T-S 24mm 1:3.5 ED AS UMC lens looks interesting, especially if I go for a D800. Will hold off till the reviews are in. By the way, if you have a Hasselblad wide angle sitting around, there is a mount, the Kipon Hasselblad V mount CF lens to Nikon F Tilt & Shift Adapter for D3X D4 D800 that runs about $350US or a plain shift adapter for about $150. Since those lenses were meant for Medium format, there is no problem with edge sharpness.

JK- Samyang just announced a 23mm PC lens. No idea if they make quality stuff or not - though their name does seem to come up quite a bit lately. No price announced yet, but I think they are generally about 1/4 to 1/3 of Nikon price? Tom

Yes I posted a link to the new Samyang PC lens above.. Rumours says that the lens will be $700 in US so maybe £500-600 in UK. Samyang produce very good quality stuff both in build and optical quality but only with manual focus so it shouldnt be a problem. Autofocus is superfluous with PC lenses as manual focussing is a must. That looks fine for the use it would get but if I could get the Nikon 24mm f3.5 PCE at a good price I would probably go for that.

I can't help thinking that nobody can make a $2000 lens and sell it for $700. The reason for using a tilt shift is to extract the last ounce of perfection from the image, can that be achieved with a lens 1/3 the price? Even the Nikkor suffers noticeable CA at the edges according to the review I read. Because of the construction of a DSLR it's impossible to use a true tilt shift , so it appears the PC lens is split onto two sections, an image gatherer and an image projector. The tilt shift effects happen at the intersect of the two sections of the lens and the resulting image is projected to the mirror/viewfinder or the sensor during exposure. I think the wide angle Hass idea is a good one but I wonder how the DSLR snags are overcome, if they are? Seems to me there has to be vignetting at the more extreme tilt-shifts?

What's different about the construction of a DSLR vs. a film SLR, except that there's a sensor in the same location that the film would reside? The shutter, mirror, and mirror box are pretty much the same. The lens bends light rays around and shoots them out the back of the lenses mount. The tilt affects the angle at which they emerge. The shift affects which portion of the image circle is used. How does what's behind the lens mount change any of this? There's also all those extra electronics in a DSLR but they don't affect this discussion.

I was comparing it with a true, say 5x4 technical camera. The Nikon tilt shift lens is in two parts, the front part which does the tilting and shifting, and the 'projector' part which projects the image straight onto the sensor (or film) A DSLR (or SLR) has a narrow port where the lens attaches, the image must be projected straight into the camera, the entire lens can't tilt or shift much or the edges of the lens mount would obstruct the sensors view of the image, it's like the body has tunnel vision. A technical camera has none of these constraints and can tilt and shift using any standard lens. An SLR or DSLR can't, at least not more than a degree or two, and not with a standard Nikkor lens. The PB4 bellows allows slight tilting and shifting, which can be useful but if using a standard Nikkor the image circle could be a problem, and it's only any use with either the 105mm F4.5 Bellows Nikkor or a similar lens like an EL Nikkor. That's why the PC lenses bend in the middle.

It should work OK on a smaller format but as you say lens coverage may be an issue. PC lenses tend to cover more. Chromatic aberration is fairly easy to correct these days
