Does that include the 300 f4?

There’s a story of something similar in New Zealand that included 3D printing a small broken component because official parts were just not available.

Great to hear you found a resolution on your trip Peter 👍

That’s great, thanks.

Can I ask some questions about this lens in general please?

Does the OS work in the lens in Pentax mount, or do you have to just use with in body?

And how’s the AF? Is that electric with this lens or Pentax in body screw drive?

Thanks.

It is indeed expensive and is already nearly 4 years old.

The K-3 iii was on my wishlist but it's been a really odd ride, in terms of pricing hasn't really changes much and it's fairly niche in terms of not many on the second hand market either. By the time I get there it will be quite out of date but still running at close to original pricing. The monochrome option is something else to filter out now and I find ebay hard to tie down to UK only (am I missing something here? - sort by near me seems to work ok but still a lot of Japan listings I'm not ready to commit to).

I'm still running an original K-3 so would very much like to upgrade that now. K-1 in a similar pricing area but obviously wildly different strengths and weaknesses. I believe most of my key lenses are crop so that's the piece that puts me off the K-1 addition personally.

I’m exactly the same. Long overdue for an upgrade but the K-3 iii seems quite rare and therefore holding its price longer than expected.

Nice!

Agreed. To make this more appealing it would need to adapt a new mount, which means developing a new range of lenses. Canon tried this with the M mount for example and it's risky and costly. Would be heading into partnership territory, like a native sony E mount but supplied with a fully AF capable K mount adapter, and option to purchase an adaptor for the earlier pentax screw mount too.

It's that extra line of lenses that I don't think would get this going, too much investment.
