The new Limited editions designed and optimised for DSLR, performing better on DSLRs. And the tests show this. End of story.
As far as "performing better" even that is purely subjective to taste and the subject matter of what you're shooting. I read all the same tests and reviews and studied all the graphs and charts when I dumped my Canon and "L" lenses and bought into the Pentax system not so long ago. I thought a lot of the FA Ltd hype was wanting to agree or be agreed with, having the more expensive lens, and such. Being one of those analytical technical minded people that I happen to be, I decided to purchase the DA limiteds DA40, DA70 and DA35 when it too came out. I had figured that the newer DA's were optimized better for digital and had better sharpness across the frame and were more "homogenous" (I've seen that one poorly translated quote from 1 particular website repeated over and over..) etc...
So, I was thinking the DA's would yield a better digital image than the FA's would. I was positive of it
I was also thinking that some of my old M lenses I had for 25+ years would also be a nifty novelty and not yield images as good as the DA ltds either.
But that was my arrogance (I define arrogance as knowing something without trying for myself)
Later and recently I purchased the FA 43 and FA77 (just because) and I tried them out and compared real world usage of my favorite model, and my favorite scenes, and I diligently recorded the details of handling and usage and focusing and how the raw images processed and skin-tones and overall image and tone, how they printed on my printer, and lots of other things that I tested just for myself for no-one else, and I kept the lenses I liked the best and sold the ones that came in second. I wound up with a mixed bag, and very much different from what I thought it was going to be...
But my point is that all the charts and graphs and reviews can only possibly help you to narrow down which lenses to try out for yourself, not which lenses to proclaim as the best and buy them on that basis alone. For instance I liked the way the DA70 rendered scenics and a bunch of other things a lot better than the FA77. But my usage in that focal length was for portraits, which I preferred the FA77.
One of my overall favorite sharpest lenses that I tested was an M lens that I've had all these years, it beat out the DA and FA in sharpness, color, detail, highlight and shadow detail - you name it. And that obviously was not designed for digital at all.
So my favorite primes set so far consists of (all by my personal testing, for my tastes) 1 25 year old M, 2 FA limiteds, 1 DA limited and 1 Tamron.
I haven't made my mind up yet on the below 40mm prime, it might be the FA31, it might even be something else. I just picked up a "something else" that is a 30mm and man it is a beauty, real sharp, rich colors, I want a FA31 very badly, but I'm willing not to own one, that's ok, but I will now rent or borrow a FA31 before deciding which one I myself like the best...
