The 17-70 hardly ever leaves the front of my K20D despite owning the DA*16-50, could I ask if you've had the AF sorted because it sometimes won't lock focus between 50-70mm? I'm using the "rest your finger on the focus ring" trick with mine, but if there's a relatively inexpensive fix I'd be interested. It's a fine lens if a little frustrating when it won't lock focus. BTW mine wiggles a little when extended, just a little bit though.

No problem

Hi Alexander, one listed here:

These were early attempts, I got better with practice I still find the combination more than acceptable even with the SHQ 1.7x. I agree with Philip, that's a lovely image. I find the Out-of-Focus rendering (Bokeh) harsh/busy with many longer zooms. I've thought about Sigma 120-400 and 150-500 many times but decided to stick with what I have.

Used it with the Teleplus (Kenko) SHQ 1.5x and 1.7x also the Tamron 1.4X, SDM works, slight loss of resolurtion but mainly at the edges, slight loss of cantrast was more noticeable, never noticed any CA. 1.7x is worse then the 1.4x or 1.5x (obviously) there's a tendency for the AF to hunt either side of the subject with the combo unless tripod mounted. Some sample images K20D + DA*300 + SHQ 1.5x:

Thanks for the interest, sorry I can't be of more help.

Regards,

Ditto.

Hi Steve,

PM replied, thanks.

Hi Alexander,

It would be rather too big I think, the case you need would be soft case: S80-160.

John

Still looking.
