The purpose of this thread is only to count the Pentaxians interested in this nice lens that is currently only available in Canikon and Sigma mount for now, although it was initially announced for Pentax too.
120-300mm F2.8 EX DG OS APO HSM
As changing a mount should be neither complicated nor expensive for Sigma, it is important that Pentaxians prove their motivation and show a potential market for the lens manufacturer.
For the moment, there is no 300mm f/2.8 in AF version for Pentax, except the Sigma 300mm fixed focal ! But the 120-300mm is less expensive, has the same optical quality, is weather-sealed, has HSM and most of all is a zoom (you cannot be too close of an animal anymore). With a doubler, you obtain a splendid 240-600mm f/5.6, which is a superb competitor to the mythical Pentax FA* 250-600/5.6 ED [IF], but with 2kg less and a shorter minimal focusing distance.
So please, all of you interested here in long focals, make hear your voice ! When we get 1000 signatures, we will send it to Sigma. A market of $4700 x 1000 Pentaxians= $4 700 000 cannot be neglected !
Come on, sign below !
