Great sharp and colourful shots. What is that honeyeater doing in a Norfolk pine? No blooms to be had there.

also had trouble with back focus....... ended up at this point with +10 correction........ still doesn't quite match LV focus.
After further use, if it continues to display a lot of back focus at the very edge of your adjustment range, I'd consider sending camera plus lens back to CRK for adjustment and calibration together. Or ask them to swap you over to another lens sample, which might mate better with your K-3's tolerances.

With that lens you need both to be steady!

Curious if anyone with this lens also has or has used a Pentax A* 600mm? With the 1.4x TC this lens would give you 630mm f/8 as opposed to 600mm f/5.6. But loss of one stop aside is the image quality close? I've been eyeing a 600mm f/5.6 for sale and wonder if it would still hold up to this lens and the TC.

Aside from the points you mentioned, the AF would most likely struggle too.
Is AF important for you ? If not, consider my comment as useless

I have seen a number of posts indicating AF on the 150-450 works just fine with the 1.4x TC. But if comparing it with a 600mm manual focus lens I guess one should ignore the AF to be fair. So I suppose if the AF does work, even slowly, that would be a plus and if it does not then not really an issue as the 150-450 has quickshift.

I'm just curious if anyone has tried the 150-450 + TC combo and been able to compare it to the A*600. There are three or so available on auction right now at about the same price as the 150-450. I don't currently have a long lens and might just go for the 600mm but for the same price the 150-450 is a much more modern design.

Sorry, somehow I didnt get the A* (as opposed to F* or FA*). Of course in this case a AF even approximated is a bonus.
I'm curious too although I suspect the A* would not be much better. The 150-450 is that good but that's from my perspective, pictures i've seen and I never owned any of these.

I was poised to try this combo out on the super moon eclipse, had everything set up including the tripod. Unfortunately, Michigan, renowned for it's weather changes went from a sunny afternoon to a clouded in evening and I never even saw the moon, let alone try to take pictures.

LOL, we had the exact opposite. It was supposed to be overcast so I did not even bother to go out. Woke up early in the morning with the moon shining through the windows. Watched for a bit and decided to go back to bed...........

The only thing I saw that night was a brief picture on our local news of a vague reddish ball mostly hidden by clouds ... until more clouds moved in and completely hid it. Move a dozen miles north, and I would be in southern Michigan, so I guess it's not surprising that my experience was more like that of Tom S than that of jatrax.

Oh well..... first couple of HD DFA 150-450 shots from my back yard. Was having problems yesterday with the lens....... it didn't play well with the canon "S" screen in my K3 (exposure issues)..... so replaced it with the original (once I found it!)..... also had trouble with back focus....... ended up at this point with +10 correction........ still doesn't quite match LV focus. Anyway.... I bought this lens because I wanted about 450mm in reach (on APSC) and the flexibility of the focus range. Any shots you see from me are just walking around and shooting..... no tripod.

450mm, Iso400, 1/200, f7.1


450mm, Iso200, 1/400, f7.1

Looks like a great lens. Shot #1 is very nice, sharp, clear, good colors.

A field test report by Anton Tsyupko of using the 150-450 to shoot commercial and military aviation, with aviation images and some commentary about pros and cons of the lens and it's features. Via Ricoh Russia:
