Just about acceptable for a long term investment?
The Canon 400mm f4 DOII is 6799,- in Europe. The DA560 is 5699,- in Europe. The Canon of course still needs a 489,- 1.4ext.
For me, it is possible to trade in the DA560 + HDDA1.4tc. So I am not starting from scratch. Honestly, the few thousand that I will lose on the DA560 trade in, will have been more than worth 5 years of images that only such a lens can get you, and let's not forget the satisfaction that using such a lens brings. So it is a bit different than with more regular lenses.
Ultimately though, portability and BIF AF are the decisive points. I cannot e.g. take the DA560 on a plane in hand luggage, and I am planning to go on various trips in coming years.
I know Pentax does not make such specialty lenses, they would only sell a few, and the DA560 itself was somewhat of a surprise. But chosing such a lens also has some very practical considerations. A compact 400/4 lens that takes converters very well is definitely a niche lens.
