There is an in depth review on the site, from my phone I can't link to it. I found the review to be more critical of handling than the reports I'm seeing from users of the lens. I don't have it so I can't provide direct feedback but all of the users who I follow that have it seem to love it. Also the review and their shots seem to both agree this lens nailed the image quality above all else.

There are also two threads with comments and pictures. On my phone or I would give you the links but a quick search should find them. Both have been going for months so lots of content.

...then you definitely deserve this lens.

I do not own it but tried it at the Pentax (Ricoh) booth at a trade show when it was first introduced.

It is a large lens, which is expected from a lens of this focal length. The dozen or so images I shot with it exceeded my expectations. As you know the price is a little steep but if I were in the market for a lens with this focal range, I would not hesitate to purchase it. It is a pro class lens with the rugged body and excellent glass inside.

BTW, I shot the lens with a K3 and the focus was very fast and accurate. Especially given the dimly lit environment of a trade show hall.

Inevitably the lens is big & heavy - - there's no way 450mm will be like a 70mm f2.4. The image quality is very good, probably better at the long end than a 300 f4 + 1.4X TC. Accurate focus is idiosyncratic, sometimes spot-on right out of the box, but sometimes a particular K3 + 150~450 combination needs a focus adjust to nail the AF, so test and tweak as needed. DOF is extremely shallow @ 450mm. If the focus is off by a two or three degree twist of the focus ring with the aperture at f6.3~8 it can throw your subject into bokeh-land.

If you have the money, just buy it. It's the best available option from what I've seen. You can spend a lot of time messing around, buy something cheaper and in a few years still end up wanting it. Plus as the newest design, it has a recently designed ring motor, it's optimized for the faster AF capability of the K-3, K3II and beyond.

The problems you may have with handling will be true of any long lens, but it is worth thinking about if you don't have a 400-500mm lens. You don't just walk out the door with these lenses and get great images, on the first go round. They take some patience and perseverance., some new heavier tripods, some new portability issues and some gym time to build up your comfort level when carrying heavy gear. If you plan to have the same portability and flexibility you have with shorter lenses, the DA*60-250 and TC might be a better option.

I'm not sure, I think I've read the DA* 300 and HD 1.4x RC are better...

Maybe marginally better, maybe not, but focus is going to be much slower.

Not to mention a prime lens is much less versatile than a zoom.

Why?
Both are focussing at F5.6.

Because the DA* 300 is using the old SDM, and even before adding a TC the focus was never fast. The 150-450 is using a new ring motor and is optimized for focusing with the K-3/K-3 II. It also has the 4 AF buttons for focus presets.

+1 60-250 for example has lower keeper right in difficult focus tracking condition than the 55-300. SDM was a big mistake...Hopefully we are now at the end of this era with all new lenses using DC or another manufacturer implementation (like the 24-70 SDM that rely on a Canon AF motor).

The 150-450 on the other hand was designed to provide a great AF experience.

question on 150-450

It would be nice to see test of Pentax 300/f4, sigma 300/f2.8 and new pentax 150-450 used with k-3 ii. Thinking also getting new 150-450 but Sigma's big aperture is tempting especially because like to shoot in dim light. Still, if using tripod (which you most propably will do), aperture advance is not that major issue, and betting Pentax lens focuses better.

I do not have a Sigma 300 f2.8, and I have an original K3 not the K3 II, but I did a series of tests of the 300 f4 and 150~450, both with and without a 1.4X TC. Posted on the long lens (300mm or longer) thread.

Since the thread is huge can you link to the post that starts the comparison or summarize the results here?

If you can find the "The 300mm plus lens club discuss your long lenses" - my posts start on page 1259. I was testing four lenses (60-250, 300, 150-450, and Tamron 400 f4; without and with the 1.4X TC; and for the Tamron I also tested with the Pentax 1.4XL and 2XL converters. Here are some conclusions:

-
1) The 60-250 with 1.4X does not match the IQ of the 300 with no TC.
2) The 300 + 1.4TC does not match either the 400 Tamron or the 150-450 without a TC
3) The 150-450 with 1.4X TC seems to be a compatible combination that shows only minor IQ loss and is an acceptable way to get to 630mm
4) The 400 f4 Tamron works well with all three TC's
5) The Tamron 400 + 2XL gives very good results, probably the best combination among those tried for photographing a small bird. CAVEAT: This combination is extremely difficult to focus, the slightest touch causes major vibration, and two stops down from f8 (the test aperture) the effective aperture is f16. This is a combination for bright light, high ISO and a massive tripod, preferably with double support (lens & camera body).
