But with stabilized camera bodies and all...
I've used the Sigma 300mm at below 1/1ooth, especially while panning with moving objects. If one is able to practically stabilize somewhat; one could easily go for a significantly slower shutter speed

To those that might believe that it would cost more to add in that aperture ring... It does not. Even Chinese nameplate lenses have aperture rings and also happen to be right in line with some of the least costly lenses on the market right now

This looks like a "K-3 replacement model announcement is imminent" thread!
That's why I asked how long the offer was on for
Interesting that two other people have noticed that one.
At the trade show in Vegas, some reps off the record indicated that the K3 might be "both still on the market but also replaced by a higher end model", but it gets better... This year. More than one rep said this, but unfortunately nothing quite official.
But it was also stated in the general audience of a Nikon rep, who did later state... That they believed the Pentax information was accurate, but at a "cost". The cost... That the new Pentax flagship would be priced **higher** than a planned Nikon entry level full frame

no one else has successfully developed such a retro camera to date
Could it mean incorporating retro camera features into a modern camera?
If so, I have several Leica outfits that fit the bill. Everything from Leica camera bodies such as the Leica Monochrom (sorry I do not wish to purchase the extra vowel) to the Leica MP, to most all of the Leica branded lenses - with a few exceptions. Even the Leica f o.95 still very much uses that front of lens aperture ring

Yet soon Pentax will not even be capable of making top five numbers

10+ Sigma lenses are not available on PK, but sell quite well in Nikon, Canon, and even Sony. One of the best lenses currently produced for PK is also a full frame lens; the Sigma 24-70 f2.8
Maybe if there could be a petition started to find what photographers really wanted to be available in PK, then forward both an email and a written copy to a few of the manufacturers

Anyone tried it on Sigma lenses? How does it fair with HSM?
The teleconverter combination does work AS WELL with the following Sigma hsm variations...
1. Sigma 50-500; at the most extreme telephoto end due to the aperture, but easily corrected if zooming out a bit or with a bit of focus hunting
2. Sigma 150-500; same issue as above
3. Sigma 18-300; same as above
But try to figure out this math... Using either the teleconverter or not... That focusing still works better using Sigma f6.3 (again, teleconverter or not) than Pentax glass at f5.6.
Proven case in point... Those Sigma lenses mentioned above (all Sigma hsm) using the minimum aperture at f6.3, versus Pentax glass such as the Pentax 16-85 or even the Pentax 18-135... The Sigma glass wins. Do not know why, do not know how

1. Which Pentax camera body?
2. If K3, which variation?
3. What firmware update shows as being updated to?
4. Have the attempts at photographs been tried in a variety of lighting conditions; time of day, even flash?
5. Does it appear over saturated on just one single computer screen, on camera screen only, or even when printed?
