If you want to avoid con­verg­ing ver­ti­cals in your shots of build­ings, this is the lens to go for

Most lenses project an im­age cir­cle that is just big enough to cover the sen­sor, but tilt-shift lenses cover a wider area. They work by slid­ing the lens el­e­ments up, down or side­ways, which has the ef­fect of slid­ing dif­fer­ent parts of the scene into view. The main rea­son for want­ing to do this is in ar­chi­tec­tural pho­tog­ra­phy, to keep ver­ti­cals ver­ti­cal. Oth­er­wise, if you stand rea­son­ably close to a build­ing, then even with a wide-an­gle lens you need to tilt the cam­era up­wards to take it all in, and the re­sult is a shot in which the sides of the build­ing con­verge from bot­tom to top.

The pro­ce­dure is to aim the cam­era level, which gives you a view with too much fore­ground and of­ten cuts off the top of the build­ing. But then, by shift­ing the front sec­tion of the lens up­ward, you shift the view up­ward also, but with all ver­ti­cals stay­ing ver­ti­cal. Adding tilt does some­thing quite dif­fer­ent – it tilts the plane of sharp fo­cus so that you can align the fo­cus bet­ter to a sub­ject (like still-life ob­jects on a ta­ble), or do the op­po­site to throw parts of the scene un­ex­pect­edly out of fo­cus. We’ll delve into this in a forth­com­ing is­sue, when we look at depth of field.

Ear­lier Nikon lenses, like the 28mm f/3.5 PC, of­fered just shift, but now the range of spe­cial­ist lenses com­bines shift and tilt. The Nikon 24mm f/3.5 PC-E, Nikon 45mm f/2.8 PC-E Mi­cro and Nikon 85mm f/2.8 PC-E Mi­cro all boast both shift and tilt. Third-party Nikon-fit lenses in­clude a range by Sch­nei­derKreuz­nach and Hart­blei.
