Too soon to say for me... I've had the Tak20 for only three weeks now. I noticed right away that it has nice bokeh, flare resistance, handling, colors (Tak) and is plenty sharp, close focus... I really dig it. I've had the FA20 for almost a year now. It gave me some really pleasing images on K-3, and some nice ones so far on K-1 too, but we went through some tough times together, when I broke it in June (while trying to remove a cheap hood I bought on ebay that was stuck, and it could no longer auto focus...) so limped along with it until getting it repaired last month... It has many of the same strengths as the Tak20, and it's AF and F2.8... Both have barrel distortion adn weight about the same... So yeah, if it was a pry them out of my hands contest, I don't know which one I'd put in my right hand...
I need to take them both out on a nice sunset/landscape shoot and compare them more closely, which usually isn't something I'll do... I did compare them both indoors the other day, and here are the results.. Unfortunately didn't keep the exact framing (travel tripod on chair)... Both F8 and 1 second exposures.. Lighting a litte different on each as I was holding a lume cube:
Tak20:
Fa20
Starbursts are another (minor) factor for me... On crop I am a DA15 flare/starburst fan and hope that RP releases and FF clone of the DA15 someday... I was familiar with the A20 from looking at images from others here and flickr, with its 10pt starbursts, and had read that FA20 is the same optical design as A20, so was excited when I had my chance to score FA20 at a deal last year. But then it was a bit of a disappointment when I first saw the 6pt starbursts from FA20, which I just don't like as much as the 10pt from A20 or the 14pt DA15. Just a minor detraction though.. It's actually been good for me in a sense because it takes the whole 'fishing for starbursts' factor out the equation when I am composing shots...
One of the first things I did with the Tak20 was check for starbursts, as I hadn't been able to find examples online prior to purchase, and then I found out why... It doesn't really seem to produce them. So far at least I haven't seen them, but I need to try harder. When the lens is wide open, in my couple tests so far it produced flare off the sun similar to my Preset Macro Takumar 50/4, though they are obviously different designs. The Tak20 is 'automatic' diaphragm, which I don't know what that means technically but I'm sure you could explain to me... I can say that so far I prefer the Tak20 "no starbursts" over the FA20 six pointers...
Here are the couple test shots of the Tak20 wide open sun flare. (Don't know why I didn't stop the lens down too... Guess I was busy in the moment being too enamored with other aspects of the lens):
Originally posted by Dartmoor Dave Wow, that's a beauty. Everything about that one works perfectly for me.
The 24mm seems to produce cooler colours to my eyes, probably more natural actually, but without that wonderful romantic glow that makes the 20mm so addictive. And of course the SMC has got much stronger contrast, almost too strong for my taste because I prefer a lower contrast look. That's why I'll always go for a Super Tak over an SMC, but it's a purely personal thing.
Thanks! And yes, my Super-Tak 24mm does have the more natural colors and lower contrast comparitively. The other thing my copy doesn't have is the ability to focus to infinity. I was contemplating trying to adjust it myself but have put it off for now because I am probably not keeping the lens long term...
