Review Lens: Lensbaby Sweet 50mm F2.5 Pentax

Lens Overview - Lensbaby Sweet 50mm F2.5

A bright normal-length lens with a unique tilting design, the Nikon F-mount 50mm f/2.5 Sweet Spot Spark Lens from Lensbaby affords you extensive control over selective focus effects for producing creative images in-camera. Compared to the original Lensbaby Spark, this dedicated optic is notably faster and offers an adjustable aperture range from f/2.5 to f/22 for controlling how large the sweet spot of focus is. The distinct tilting lens body also allows you to position your area of focus about the scene in order to draw attention to off-center subjects and dramatically blur away other portions of the image. The lens itself is a multi-coated glass doublet, which produces the distinctly sharp yet ethereal image quality Lensbabies are known for, and the flexible housing permits manual focusing on subjects as close as 9" away.

Normal-length 50mm f/2.5 lens is suitable for use with FX-format Nikon F-mount DSLRs, however can also be used with DX models where it will provide a 75mm equivalent focal length.
The f/2.5 maximum aperture is notably brighter than the standard Spark optic, and its adjustable range to f/22 affords more control over how large the selective focus portion of the image is.
Flexible lens body produces the distinct Lensbaby look and allows you to control where the sweet spot of focus is in the image area.
Lens body also permits manual control over focus, with a minimum focusing distance of 9".
Multi-coated glass doublet optical design.
