Particularly hard-hit is the Diopter Correction Lens Adapter M, for which list pricing will double in just over three weeks time. The Rear Converter-A 1.4x-S and two of Pentax's lens hoods--the PH-SA49 and PH-RA49--are all set for list price increases of nearly 80%. In general though, most products affected by the price adjustment look to have seen a more modest 30-50% increase, and in some cases customers will pay less than 20% more than was previously the case.
