Hi,

Anyone has tried to use the DA* 60-250 with the old (not the cropped version) RC 1.4x? Are they compatible without the risk to damage each other?
Thanks

Bernard, please add a purple fringing test (above all for the 77mm) and, if you can, a color balance test on film. Thanks!

Great work!

I changed the backup battery of mine k-r and now no more main battery drain and no more 10 shots then empty. I followed this guide:

Is 60-250 really full-frame?

I know that there is an optional tripod collar but it is very awkward, it's huge, you have to disassemble it to remove or install, no click stop at 90....

Ehm... a lens must also be carried and in my backpack the space for the "70-200" zoom is exactly the size of the DA*. I can't also add the huge and "not so smart" extra tripod collar.
When the lens is attached to the camera the length is not that important, above all if this means an advantage in the focal range. Another plus is the CPL window in the lens hood.

Sure it hasn't the circular iris, the HD coating, the new SDM and the AF is a problem (mostly because is prone to fail so often a slowness report is in reality an SDM fail report) but my experience with it says that it can be used with a K-1 with great satisfaction.

My DA* 60-250 AF almost die one month after the warranty expire... the service center is charging me of 200 euros...
I have not changed it because the 70-210 is a little longer and does not have the tripod collar.

Was a (not mine) K f/1,2 at minimum focus distance, camera was an MX and the film was the Ilford HP5 plus 400 ISO.
The shot is to demonstrate the field curvature, not the sharpness.

The smc hasn't ED elements and the HD hasn't one less element, both diagrams on PF are wrong.

p.s.: about the name the only hint about the optical construction is AL that is for Aspherical Lens, ED is not present.

HD Pentax DA 560mm f/5.6 ED AW replacement : what are your thoughts ?

I think that they will replace it with a prime lens with less focal length, maybe more speed but surely two dedicated RCs. I bet on the 400mm f/4.0 .

Almost true :cool:



True but you can do focus stacking programming the focus point of a certain number of shots.

Questions about:
- the future developements of the full frame (OVF and tech from the K3 III ? ... without the lack of GPS and articulated LCD...)
- the future developements of the 645 (full 645 sensor?)
- the future developements of the lenses (a companion for the 70-210 f/4 like a fixed f/4 24-90 or 24-105? They want to extend the in lens SR technology also to the FF and APS-C lenses?)

extra question: they are aware of the poor sharpness delivered by theirs JPEG engine compared to other softwares that develop RAW like Camera RAW?
