Review on Tamron 20mm f/2.8 Di III OSD M1:2 Lens: Perfect for Sony Full Frame/APS-C E-Mount Camera Enthusiasts by Candace Carpenter

I need a lens with a larger angle than 35mm for my Sony A7riii. Seeing samples of Sony G Master 16-35 2.8, I decided to check the price. After laughing at the $2200 price tag, I had to decide between this $300 Tamron and the $900 Sigma Art 20mm 1.4. I chose this lens because I had such great experiences with my 70-200 2.8 g2 work lens. For $300 I was expecting a mediocre lens that I will regret buying. After returning from a trip to the Smoky Mountains, I was amazed at the photos captured with the lens. COLOR POP and contrast really bring photos to life. (2 examples I uploaded are directly converted to jpg). This lens is "soft and creamy" rather than "razor sharp" like the Sigma Arts and Sony G Master lenses, which is both good and bad. You can sharpen to your post requirements and still get a great image. My 35mm Sigma art is sometimes too harsh for landscapes and can make blades of grass and tree leaves very noisy and uncomfortable, so this isn't an issue for me. At 2.8 it's too soft. f4 to f13 is perfect. F16 is a bit soft and needs a bit of crispness and sharpness in post-processing. No, the autofocus isn't lightning fast like other reviews say, but it's not sluggish either. I like that it's weatherproof, but wish it had an AF-MF switch, which is essential for astrophotography and shooting in very low light. You need to use the back button autofocus to fix this problem. It's a nifty little lens capable of capturing excellent image quality. For the price, I have no complaints about this lens other than there is no AF to MF switch. Grab it and use the dollars saved to buy that other lens you need!
