The Pentax O-ME53 Viewfinder Loupe magnifying eyecup works with all Pentax DSLR bodies and offers 1.2 times magnification over the entire image field. This is ideal for critical focusing (e.g. macro photography), and when using manual focus lenses.
Eyecup FQ for K-r Digital SLR Camera
This is a replacement Pentax Eyecup FR for the Pentax K7 SLR digital camera.
The Pentax Auto Extension Tube K Set contains three tubes of different length - 12mm, 19mm, and 27mm - which can be used individually or in any combination to obtain the desired magnification.
The Cable Switch 205 from Pentax has a 1.6' cable and will help prevent camera shake when shooting super telephoto shots, macrophotography and bulb exposures. Handy for taking pictures of subjects that are difficult to approach, or to minimize vibration for close-ups and time exposure.
