>>4084407>with APO and ASPH elements.Uh... Wrong... While were at trash talking of Sigma and Tamron, I have something to add:
Not a single Sigma or Tamron lens in existence, in both of their entire manufacturing history, has ever had an APO glass element or a real aspherical lens design. Not one lens. In addition to that, neither company makes decent aberration control coatings for their glass, let alone having actual apochromatic glass elements. To top that off, Sigma was always known for having absolutely terrible, flat rendering, regardless of the lens being ''clinically perfect'' or not, not a single lens they have ever made, displayed even the tiniest bit of proper color saturation - micro contrast rendition or dimensional rendering of objects. Not one, single lens.
Speaking of Sigma, I still remember when my friend, who is a Leica dicksucker, thought that my lens was a defect lens when I borrowed him my 5DmkIV and my brand new Sigma 1.4/105. Took me 10 minutes of back and forth messaging, trying to figure out what he's talking about, before I realized, started laughing and told him that's just a Sigma lens. Yes, Sigma lenses are so bad that a person who shoots Leica thought I got a defect lens... Let that sink in.
Tamron does not have dimensional rendering either but at least some of their lenses manage to render in SOME micro contrast onto the image sensor, whereas Sigma lenses are just optically garbage all around, which is ironic, because their tip-top lens lineup is called; ''Art.''
