Is that unique to that lens John?

That's a good number, I recall my gx20 doing around 65,000 which I thought was a lot

Interesting you say that, Mercedes have just rebadged the renault kangoo van, will that be a good product?

But how will you know its the best if you haven't tried it???

Hmm the use of a teleconverter is a good idea for longer glass maybe the 300mm f/4

Is there a different motor in the 18-135 then???

Didn't SDM speed also improve on the k-7 / k-5 too???

Last quote I had was around £125 and that was with the new upgraded parts

When I compared my 50-135 on an old k110d (screwdrive) to my GX20 focus speed there was very little difference in AF speed. I think the noise of screwdrive creates an impression of speed.

Here are some shaky videos I made at the time

Screwdrive

SDM

How many of those voting actually owned or have used those cameras???

Its a similar issue to forums when someone asks what lens or body to buy? Most people answering only express opinion about the one lens or body they bought without being able to compare it against any other body or lens as they have nothing similar to compare it too. But as that person bought one the need to justify it as being a good purchase is necessary.

Post-purchase rationalization (buyers stockholm syndrome) is an interesting study and worth a google if anyone is interested in that kind of thing.

Why???

All those lenses will work with screw drive only bodies, if its to get around a broken SDM lens then repairs with the newer parts can be done fairly reasonably.

I don't see the point of this...
