I had and have a lot of different lenses for both Sony and Canon. I shoot on crop and ff. There were other systems. In short, there is something to compare. There was sigma 30 / 2.8 and 30 / 1.4 - in general, I am a photodro. Er :) And yes, I look at the pictures pixel by pixel (with the exception of helios), because I buy photographic equipment to get the maximum quality, otherwise take off the phone. This lens is flawless. Yes, I would like a stub, but I would like 1.4. But it’s other money to take at least 56 / 1.4 - on the secondary it’s about 28K and it’s also without a stub. And with a stub, you can take Sonya 50, but terribly lame at 1,8 and then cover up to 2,8 :) In general, there is no ideal in life - but there is savings - this sigma, due to the low aperture ratio, weeds out photo maniacs and bokely lovers, so any whoever wants can afford a top picture for a penny, which will not burden either a wallet or a photo bag!
