There is a Classified Ads section to this forum, otherwise I'd suggest eBay.

It did come in the box, but I'm not sure it still does.

Cannot begin to mention how many cameras I've seen damaged by this
I think the answer to that would be "none", probably nobody thought a response was necessary?

Please keep to the Classified Ad guidelines. I've removed an alternative offer for a lens, please start your own ad rather than joining in somebody else's!

Many thanks!

Centering means all the lens elements being assembled so that the centre of each element is correctly aligned to the optical axis. The last general testing I have of all marques relates to 1980s lenses, so it's a bit out of date.

What was revealed then was that Pentax were actually above average in terms of accuracy of assembly. What was also revealed was that even the highest quality lenses could have decentering of even 16% and still deliver superb results.

You can't tell anything about this subject from a picture of a boat. Apart from anything else, boats move, as AP were embarrassed to realise when they stopped using HMS Wellington as a lens test subject.

That will do it. At one time one was supplied with the cameras.

I use such a lead into a digital projector as well to do teaching sessions on how to set up a camera. It will display all the menus, in fact whatever the camera screen is showing.

Both my daughters were married in the last two years, I gave up the will to live when I saw the cost of the story book albums which although they were breathtaking are produced with one tenth of the time and application of a 36 shot album of x 7x 5 and 12x8 prints or some other older enlargement size
Congratulations to your daughters!

I'm going to have to disagree on the rest of that statement though. producing a wedding book that runs to maybe 120 pages is actually very time consuming and intense. I'm doing one quite soon and Sue and I will be dedicating at least three days of intensive work to the post production of the images.

When I disappear into making the book it will be some time before I emerge, blinking, into the light of day.

That does not disparage in any way those who want to make an album of prints, I've done that too, but we shouldn't dismiss the photo book as a quick and easy option.

The term "kit lens" has become almost synonymous with the expectation of a low priced, moderate quality introduction to a range. I think that's a pity, because Pentax have some very good "kit lenses" - that is, lenses that are often supplied coupled with a camera body.

When the 645D finally came along, after years of lots of people insisting it never would, it of course arrived with a new standard lens. I'm sure if and when the Pentax Phoenix FF body arrives it will have a lens attached to it.

That must be something of a record Algi - Pentax have it all wrong before they've even announced it, whatever it may turn out to be.

150-450mm would meet my needs very nicely and could be just the lens for my bird photography.
