Just bought the FF Irix 15/2.4 Blackstone
for Pentax K-1 (More info about this lens - en.irixlens.com/15mm
My choice was because of answer from Samyang:
My letter:"... I'm the owner of the Pentax K-1 and before this Summer I'll plan to buy the hi-quality wide-angle lens for my FF DSLR.
On your web-site I saw that you designed the really amazing hi-resolution XP series of manual lenses and esp. the - www.samyanglensglobal.com/prod… . Have you any plans for produce this lens for Pentax K-mount?"
Answer:"... I appreciate you've been interested in Samyang lens.
Unfortunately, we have no plans to produce XP lenses for Pentax K-Mount which is not suitable (!!!!) for optical design of XP.
Please, stay tuned to our new announcement for launch of new lenses..."
A typical response from someone who does not know anything the matter...This is always just as pathetic. If Samyang can manufacture it optically for Canon/Nikon , of course they can do it for PK mount also....
