Pentax Lens Power Zoom

Which Camera Bodies Support Power Zoom?

All five modes are supported by the PZ series of film bodies.

Certain other bodies like the K10D, MZ-5, MZ-5N, ZX-5 and ZX-5N support the first two modes mentioned above.

The lens will zoom electrically, with 2 or 3 speed settings depending on how far you turn the lens. You'll definitely get a smooth zooming experience- however, the zoom motor might be audible in your videos.

I also own a K-5 and bought a Power Zoom 100-300 from ebay. Although the lens is usable, the powered zoom works, none of the 'fun' Power Zoom functions seem to be available - I dont know if this is because there is a problem with the lens or the K-5 does not support them.

I am a bit dissapointed as the K-5 manual and website clearly states that Power Zoom lenses are supported.

With modern SLR's having video recording capabilities, these additional Power Zoom functions become even more interesting...

I have asked Pentax support about this... I'll post the reply (which is likely to be ambiguous, defensive and non-committal :-)

PS: although I am not an experienced photography, I think the lens is great, especially with the K-5 SR system.

The only thing the functions with the Pentax DSLR's is the power zoom, the other functions such as zooming during exposure that worked on the PZ-1 do not work.
