The new Pentax DA 18-270mm F3,5-6, 3 ED SDM is a versatile lens that will improve the 18-250mm one launched back in 2007. Designed for digital SLR cameras with an APS-C sensor (Kx, K-30, K5II …), it will find its place in frequent travelers camera bag. It is updated with the SDM ultrasonic autofocus motorisation that offers better speed and silence focusing. The lens diaphragm gets 7 circular aperture blades to get smooth and soft bokeh. Pentax has used some ED glass in the optical formula and the Super Protect treatment (SP) is applied to the front lens which limits the persistence of fingerprints and is water repellant. But albeit this SP treatment, the lens is not weather-sealed and therefore not “WR” as the smc DA 18-135mm f / 3,5-5,6 ED AL (IF) DC WR recently announced with the weather sealed K-30 , a bit annoying for lens dedicated to travel and that will possibly have to face tropical moist or desert dust, etc..
