I hope that means I may finally find a replacement for my Tokina 28-70 ATX-Pro f/2.8.
The Sigma 24-70 is all right, but I really loved that Tokina lens. On 10/27/2017 14:45, Igor PDML-StR wrote:
Although I cannot find the official announcement on the Pentax website, the way it is quoted (or possibly paraphrased?) says: "Newly developed ring-shaped SDM" See it e.g. also on this site: http://www.photographyblog.com/news/hd_pentax_d_fa_50mm_f1_4_sdm_aw_and_hd_pentax_da_11_18mm_f2_8 So, we can hope it will not have the same problem. Regarding Tamron origin. I sort of doubt that. I just googled, and there is no 11-18 /2.8 lens from Tamron so far. Tamron 11-18 is f/4.5-5.6, which is much slower, and also a variable aperture lens. That tells me that the optical design is most likely different. However, there is a Tokina AT-X PRO 11-16mm/2.8. Remembering the previous collaboration and association of Pentax with Tokina, I wonder if there are common roots of that Tokina lens and the upcoming Pentax lens. If you were to look at that Tokina lens, - it seems to be very similar: https://www.bhphotovideo.com/c/product/882235-REG/Tokina_atx116prodxc_ii_AT_X_116_PRO_DX_II.html Regards, Igor Collin Brendemuehl Fri, 27 Oct 2017 07:26:38 -0700 wrote: We are long past the time for retiring the FA50/1.4. And the FA35/2. HD coatings are critical. Has SDM been made reliable? All-weather (AW) looks like useful thing. And really expected these days. I hate to say it, but they *look like* Tamron packages. Hope I'm wrong.
