Yes, mainstream photography many would need autofocus right - weddings, events, sports, journalism.
I agree. I once read that the modern lens designs (Sigma Art being the prime example) which have a ton of elements can be very sharp but the images have a flat quality, lacking depth. The speculation was that they sacrifice depth and character in order to beat the "tests" which many consumers use to make purchases, because these qualities don't show up on the tests. I had a Sigma lens for my canon at the time, and once I saw this, I could not unsee it. Now, when I buy any lens or fixed lens camera, whether it be a point and shoot or Super Ikonta, I go on flickr and search for images taken with it, and look at the intangible character of the lens that doesn't show up on a test chart. I have since bought a few Zeiss lenses, they are great! As are many lenses from many manufacturers, going all the way back a century. "How do the pictures make you feel?"For me the "look" a lens gives me is way more important than MTF charts etc. Generally speaking you can't find a lens that blows your mind pictorially by looking at measured stats. In the past Sigma lenses were total crap mechanically speaking and not much better optically. I know they are trying to redeem themselves but I wouldn't touch one for at least five years so see how they are standing up to steady use. Image quality wise the photos I have seen made with them are too "clinical/technical" for my liking. They have no personality. Zeiss has a specific look that I like on my Blad, but then again I prefer the older lenses over the newer ones.
Competent photographers were taking great iconic photographs of all these disciplines before autofocus was ever invented so it's not absolutely essential.Yes, mainstream photography many would need autofocus right - weddings, events, sports, journalism.
I would choose a Zeiss lens any day of the week. Their glass is far more superior and the build quality could only be surpassed by a Leica lens. Also, there is the Zeiss pop effect that you get from good quality glass, that you simply don't get from the Sigma. Don't get me wrong, if you are just looking for sharpness from your images, sure Sigma makes sharp Art lenses. But the image is flat and the colour is not that impressive imho.
Voightlander also makes fantastic lenses. They are cheaper than Zeiss but the quality is very very good.
If you are shooting sports or wildlife, the autofocus is a massive help, so I would choose the Canon L series instead. I have 100-400L mk2 and it is an awesome lens for that. For everything else is definitely Zeiss or Voightlander or Leica if you can afford it.
I wouldn't worry too much about brand names. In my experience, I've got a few Zeiss lenses that aren't as sharp as some other lenses from other, much cheaper manufacturers. It often depends on the design and the individual lens itself. Beyond that, I try not to worry about sharpness too much. Of course it matters, but rather than limit myself to only using the sharpest lenses available, I try to get to know each lenses characteristics, and use them in situations where they will perform the best. Sometimes a soft lens, or a lens with a sharp center and soft corners will give me a better look than an overall sharp lens. They're tools. If you use the right tool for the job, it makes things easier. Scroll saws are great, but sometimes a coping saw will do a better job, even though it's much cheaper and generally harder to use.
I am just a Beginner Photographer, but......i have a Long History with Guns and Guitar Amps.
What have i learned.?....all the specs, prices, testimonies.....i do not believe "Anything" anybody says about a product until they can pick it out of a blind test, Ten Times out of Ten.
Be it powder, brass...strings, speakers, tubes...or lens, paper and developers.
The ability for people to recall with their Visual or Auditory memory is horrible.
What some guy SAYS he can see or hear is almost meaningless.....unless he can repeat it at random from samples that are unknown to him.
I have seen Thousands upon Thousands of awesome pictures that were taken with Ceil Phones and "Entry" level cameras with a kit-lens.
No piece of paper, and no bad guy ever cared what powder or bullet they got punched with.
No audience ever cares what strings or speakers a guitar player used on stage.
Nobody in a gallery ever cares what brand lens or camera a photo was taken with.
Not saying this discussion has no place or no merit.....just saying sharpness and quality of glass are the photo equivalent of Strings/Speakers/Tubes in the Guitar World.
Are we talking about Looking through a lens, or what it looks like when it is printed.?Then look through an slr with a Zeiss lens and you will see the difference.

I really do not care to compare lens when on the camera. I can see fine through any lens when it is on the body.
