Some different processing to change things up a bit - monochrome (I don't really know what I'm doing here, but there's a circle and a bunch of colours in darktable, so I moved that around and adjusted the size of the circle until the green background got pretty bright...), then just a little bit of brown split toning to add a bit of colour back to the bear.

Cool - it looks almost infrared.

I had an enjoyable weekend with the K3iii and DA 560.
This combo will never match the focus speed and light weight maneuverability of the D500/500PF combo, but it's still a joy to work with.
Chris, I compared the image quality of each on similar objects and both produced excellent images.
Here's a California quail again, this time with a nice green distant background.

Thanks, I suspected as much! I used the DA560 for over 4 years, and the 500PF now for 1,5 years. What they have in common, is true prime image quality. Both have very good light transmittance, and that means your relative iso will always be a step lower at a given aperture compared to e.g. a superzoom or a shorter prime with a tc that render dimmer images at identical apertures. I noticed that especially when I went from the bare DA560 to the Canon 400DOII+1.4TC. The bare Nikon 500PF has a t-stop very close to the aperture no doubt. With the bare DA560 I was also always able to keep the iso down. With the K3III this may be less of an issue when it comes to noise, but high light transmittance still renders better images.
Apart from the AF, purple fringing and bokeh fringing, the DA560 is still a tremendous lens, and outperforms the 500PF when it comes to reach and pure detail i.m.o.

I read though, that it is now officially discontinued, and when I asked my camera store on possible delivery time (it is nowhere in stock anymore) they could not give me an answer.

First day back home, and I was able to receive the Tamron 65B 400mm F/4 as well as do a few test shots.
So far I'm impressed, it has very little CA even wide open, and seems to be sharpest at F/8. The 1.4x Teleconverter also doesn't seem to degrade image quality, and from pixel peeping side by side, using the TC actually seems to yield better image quality than using the lens stock and cropping in post

I'll have to see how well I can hand-hold it in real-life situations. In test shots, I was able to get decent results down to 1/250s with 560mm focal length (840mm equivalent on APS-C), which seems almost too good to be true. Maybe due to the relatively short length and high inertia?
Or maybe because I've done some air pistol and air rifle shooting a few years ago there definitely are similarities.

Cheers, everyone
Leon

I've been having a long look at picking up an Adaptall 300/2.8 (I believe you have one?) as the 60B pops up fairly often on ebay and the likes - thinking it would be nice to have something for lower light in the backyard mornings where I can get close to birds and not needing quite the range

Mind you that the mount from the 60B does NOT fit the K-3iii as it protrudes and hits the side of the mirror box! It was difficult to unmount it and thanks god it didn't damaged the mirror or leaved any marks on the side of the box that seems to be the point of contact...

PS: no problem with the K-1 though! Plenty of space inside the FF camera!

Which adaptall mount were you using redpit?

[moggi1964]

Apparently I haven't posted this one here before despite it being one of my fave photos. I've no idea what camera/lens combo I used though*



*it might have been my D300+500mm which would explain why I hadn't posted it - in which case, close your eyes and imagine it better quality taken by my K1+500mm

Not baaaaaaad!

[redpit]

Which adaptall mount were you using redpit?

You’re right, I forgot to mention I use the original adaptall to K-mount adapter that offers equal to Pentax A-lens aperture control. It might not be a problem with other kinds of adapters.

[marcusBMG]

Interesting - do you think it was the aperture lever itself that was catching? You can test to see if it is the guard by removing that - two small screws.
The PKM mount is a bit different - it doesn't have the guard, the aperture lever pivots (slides on the PKA). The length of the lever is the same on both.
If it is the lever, I suspect this might be fixed by taking off a few thou off the end.

I don’t get it. I use the PKA adaptor on my 200-500/5.6 and have used this lens on my K5. I would be surprised if any other body is different internally in the mirror box area

So would I. I have used all the generations of adaptall PK mounts on: K-r, K5, K3-ii, K30 and KS2, without a problem like this. But it might only take a very slight difference. Another possibility: the slight difference is actually on the mount, the plastic guard slightly bent out of straight for example.

The red necked grebes have hatched.

That's good news - I was worried that the eggs might not hatch after the soaking they had a few weeks ago,
