Take the lens off the camera. Turn off the S/R. Switch camera on and look into the mount. On the left you should see a steel pin with a plastic mount on it with a lug poking out.

Turn the on/off button to DOF preview ( you must have optical preview enabled). The plastic mount and lug should move up as you press the DOF lever and come back down to the centre position when you release it.

Does it do this ?

I like them Jerome, especially the portrait.

Hi and welcome

I have no idea what it is ....but i like it.

Jason

following todays threads.....sure you dont want to reconsider selling it !!!

Very powerful image. You have brought out the feeling of isolation. It must be a fine line to draw between reporting on someones situation, and exploiting them. I think your approach is a good one.

I am not sure I have the courage to take this kind of photo, so I applaud you for it.

It sounds almost crass to comment on the technical aspect of the phot, but the b+w treatment and the framing are spot on.

Ralf, I think the Mk. 11 18-55 is now the standard "kit" lens. I cannot now recall why they changed it as every review of the Mk. 1 lens was favourable.... "for the price".

The Mk.1 that I have needs to be stopped down for sharpness and to avoid vignetting, so I used it on f8 almost exclusively for the Sissinghurst series. It was a fine day so that was not a problem light-wise , and I am very pleased with the results.

I got annoyed on another forum a while back with someone who had bought a "kit" and before having posted any photos was describing the 18-55 as "crap". What nonsense.

Thanks to you both for your input. I am still debating. Of course the simple question "do I need it" is irrelevent. I do have a severe case of LBA !

My signature picture was with the 18-55 (mk 1)

Despite my praise for the 18-55mm lens in another post here, I am thinking of getting the DA* 16-50mm. I like to manually focus a lot and use a split prism screen which sufferes from balckout with the slow "kit" lens.

From the review I have read on http://www.photozone.de/pentax/405-pentax_1650_28 it appears that the DA* 16-50 suffers from CA, and indeed much worse than the "kit" lens.

I do seem to recall there were quality control issues when this lens first released.

I would be grateful for any members experience with the DA* 16-50, in particular with regard to the CA.
