One thing that doesn't get mentioned as much as resolution & bokeh on the alt forum is how much better most of these old, manual lenses are in regards to their focus rings. Most modern AF lenses have very poor focus rings which makes critical focus using liveview difficult. The smooth, longer-throw of the Olys and Zeiss lenses are a pleasure to use, if you're into "doing it yourself." I don't know how the Sigma 20 is in this regard, but most of my Canons, including my Canon 100 macro non-IS, have focus rings that rate from okay to...Show more →
Yeah, this is kinda true. I always use MF. I don't even own a lens that will AF on my current body. Don't want/need one either. But I just wanted to say that Asahi Pentax RULEZ in this department! Pentax SMC are great lenses and much smoother focusing than Nikkor, Rokkor, Zuiko, Canon, Zeiss, etc.
The S-M-C/Super Takumar 24mm F3.5 is a zeiss quality match easily as good and probably better then either the Nikkor 20/4 or the Zuiko 21/3.5. And it's $50 to $100 - no debate.
Similar things can be said of the S-M-C/Super Takumar 20mm F4.5 too for about $80. It's a very sharp lens! A little distorted but not too bad really. I kinda like that anyway.
The SMC Pentax-DA 21mm F3.2 (Limited) also has superior focusing like that and additionally can AF on a matched body. I think I can say that it is sharper than either the Zuiko or the Nikkor I spoke of testing (above). And it's gotta be the smallest of all of them. And the price is right in line with what most people here are calling "reasonable" slash "cheap" - at about $350. It might even be the sharpest 21mm there is - I dunno. It's still in production too - always a bonus.
If you wanna go even wider but with the same supreme sharpness and uber-smooth focusing the SMC Pentax-DA 15mm F4 ED AL (Limited) is also very nice but it's like $500 as I recall.
