My great appreciation for the Pentax K-3ii having been well documented I have started acquiring lenses. In short on sensor image stabilization frees me to save a ton lens acquisition time since I can shop non-IS lenses. For little more than the price of one factory IS 70-200mm f/2.8 lens I can purchase three third party non-IS lenses of similar spec putting a lens trinity approach in fiscal reach. Tamron was chosen having had good luck with a Tamron 28-75mm on a Nikon D3300 in the past. The first step and long end of my lens trinity approach has been completed with the acquisition of the Tamron 70-200mm f/2.8 Di lens (28-75mm f/2.8 will be the last trinity acquisition). Next up was the wide end in the form of the Tamron 10-24mm.
Main draw other than being a Tamron? Last I checked it was the widest lens with the broadest zoom range among it’s most direct competition. A few days in and I am fully confident that I made the right decision. I will forgo listing cons since I have yet to identify any in real world use. There are no third party handling oddities like the 2 step Manual/AF switchover process on the 70-200mm. For pros I can say that operation has been seamless, it is fast to focus, pleasingly sharp, and I offer the gallery below as the final word. -ELW
