Tamron SSP 35mm f/1.8 Di VC USD and SP 45mm f/1.8 Di VC USD full fame lenses which were announced a several days ago and now you could see the reviews of about this lens and you could get some knowledges about these two amazing lenses.
“Eventually it all depends on the price tag. Tamron surely scores off the competition a little bit with their two new lenses. Of course we are talking about bits and bobs at a high quality level. Nevertheless Tamron has succeeded in setting a whole new dimension regarding the quality standard of camera lenses. Both new lenses are absolutely high-end and provide outstanding quality even for megapixel-monster cameras.” (krolop-gerst)
“Overall, I’ve found the lenses to be rather impressive, especially when you consider the $600 price tag. That puts it right at the same price point as the Nikon 35mm F/1.8 (which lacks image stabilization) and the Canon 35mm F/2 IS, which is a little bit slower and lacks the close-focusing capabilities of the new Tamrons.” (Popphoto)
“To suppress ghosting and flare, Tamron has applied both eBAND (extended bandwidth and angular-dependency) and BBAR (broad-band anti-reflection) coatings to critical elements to reduce reflections and provide maximum light transmission. This reduces internal reflections that can cause ghosting and flare to a minimum.” (layersmagazine)
“Finally, and probably most importantly, Tamron included what I consider to be the best optical stabilization available, Vibration Compensation, in both the 35mm and the 45mm. This is a big deal, as getting super-reliable image stabilization allows you 3.5 additional stops of light when shooting hand held. Shakey hands or minute vibrations to a tripoded camera are nothing to worry about with these new Tamron SP lenses.” (resourcemagonline.
