if it would be STAR it would be SMC Pentax-DA*.....
since the tape is at the end of the writing, I'll put my pennies on DA......WR

Maybe it's a foldable lens?

Rather than a zoom lens, perhaps what's listed is the focal ranges when other modules are attached.

I think it's a foldable lens. And the abrasions are confirm this situation.

Do Pentax telescopes use the foldable lens approach?

ogunturkay · 02-09-2012, 09:37 AM

And please look this patent. I think this system applied to middle part!

Patent -> Pentax patents telephoto lens that can be taken apart for easy transportation

first the new xs lens and then this one. Pentax's lens are so interesting IMO

Holy Cow! It's like Ricoh walked into the Pentax skunkworks and greenlighted everything! Go Ricoh! Go Pentax!

I know nothing about len design. but is it possible:

1. optics used in astronomical telescopes allow pentax to deliver a affordable but good quality long telephoto lens
2. but pentax needs to solve the problem of an extremely long tube issue
3. and they solved it will a new idea (to make it as a foldable len)
4. and the texts hidden in the lens' info is not related to * or wr but a new description for this foldable len (that's why they hide it now)?

Sony with its $13,000 500mm f/4 lens may have lots of bragging rights now, but in the end only a few will be sold (to order, at that). However this seems to be an affordable solution for everyone wanting more reach, at the expense of a longer than normal tube... (which hopefully can indeed be transported in two separate pieces).

I can hardly believe it. Such a price makes no sense...

ElJamoquio · 02-09-2012, 10:21 AM

Yeah, that seems WAY out of line, especially with the sigma at $5k.

The DOF is so small at 500 f/4.5 anyway, tough to imagine scenarios where I'd want it smaller.
