Don't worry Martin I thought the same thing when reading his first message.
Certainly when he said this.
So he has some explaining to do.

But to get a real figure you need to have an amount of lenses sold and the amount of lenses failed to get a true number.

For the DA*55 for example one 2 or 3 users on this forum have one, so if the fail rate will let's say be 10% how big would the change be one of the three would fail?

As for the 16-50 and the 50-135, problable the most used SDM lenses on this forum, there is a higher number of them and most of them also are older.

So all in all the figures you get now doesn't say a thing since you can not put them in perspective


Edit:
for example.
Of the 2 failed 16-50 how many good ones do you have of the members voted in this poll?
So what does those 2 failed lenses say?

You should do a poll per lens to get an at least usable figure. Since you then have failed lenses relative to working ones.

Gary, you don't need to defend Pentax.
It's one of the only brands I believe that didn't want to put behind users with an older camera that can't use SDM so also put a screwdrive with them (KAF2 mount).
Canon I believe switch systems completely in one go, leaving behind users with older camera's.
Only recently pentax have brought out SDM only lenses (KAF3) so lets wait what Pentax can do when they put more effort in that.

The DA*55 is a KAF3 mount and I must say I had higher hopes for the AF with that one, maybe the K7 speed it up a bit, does anybody knows that?

Here you go link

Would go for the metz as well because of the swivel head.
Although it support wireless it's a tiny bit crippled because it can't act as controller to trigger other flashes but you can fully use it as slave though so no worries about that.

The way to do it is use the highest F-number of the lens and overexpose the photos quite a lot.
Any dust on the sensor but also the lens will be shown then.

Only when you read his second post though, I don't think he's switching

Ken, I only see the photos.
With some of the other standard simpleviewer you can add comments, titles and such.

Interesting series.
I like the second last one since on the elements are distributed the best although the one above that push the focus more on the building (can't come up with the name :blush

The lens looks very sharp and the bokeh is smooth, just what a prime should be.

How does it compare to the 35Ltd?

Nothing wrong with the photo but simply not really interesting.
I do notice that the bokeh is very busy though but that isn't your fault.
