Distortion and vignetting in the Excellent range, plus super sharp optics. Very well constructed, but on the heavy side. Maximum magnification: 1:0.91.
Excellent sharpness at all but smallest apertures. Smooth, but underdamped manual focusing. AF limiter for full or macro range. Maximum magnification: 1:1.
Built like a tank, Pentax’s flagship DSLR has a well- designed body and records pleasing video, but its image quality and AF speed fall short of similarly-priced competitors.
Update of the D3 was the first DSLR to break the ISO 100,000 barrier, and adds video capture. If 12.1MP sounds low, superb color accuracy and clean images up to ISO 6400 make up for it.
More tele than the usual 100mm, yet lighter and faster than a 180mm—f/2.8 allows faster shutter speeds for wind-blown flora. Maximum magnification: 1:1.
With all the good qualities of the 24mm f/1.8, this offers an even lower price and better distortion numbers. AF was slightly noisy, but a newer (untested) version fixes that.
Slower by one stop, lighter in weight, much lighter in price than Canon’s 16–35mm f/2.8L, but comparably sharp, this lens is a favorite of landscape shooters. Distortion goes to Very Visible barrel at 17mm, though.
This L-series superstar has dust- and moisture-sealed build, and fast and quiet autofocus. The low distortion numbers at the longer focal lengths (0.12%, 0.19% pincushion) promise straight subject lines. Close-focus? An amazing 10.6 inches.
