Originally posted by Uluru I think DA Ltd and FA Ltd should be the bottom line of Pentax optical performance. And that means setting up a pretty high bottom line.
I call it a bottom line because technologically lenses are from film age (screwdrive), but optically they are unique and very, very good. So on top of that optical performance, make a next step up: keep the optical quality, great build quality, but introduce DC motors and WR, ll new coatings, for example.
And people will react to it, and appreciate.
To best honest, I appreciate the recent coatings of the DA ltd I tried (DA15, DA21, DA35 macro) and I have seen both HD and SMC coating depending of the lens I still prefer overall the rendering of the FAltd and I think that partially due to the coating in question.
Having used the FA77 for few years already and the FA31 for now something like 1-2 month I can say to you that yes, there a bit chromatic aberation at time that you don't see on the DA (or not as much) and also the flare resistance that is already good on the FA is better on the DA. Still for most photos, the FA just render better.
There maybe an exception for DA15, but that's it for me.
So I wonder, should we put as a standard something that is really necessary in 1% of the shots so that we win review award and get 99% of our shots noticably worse? Is that really progress?
Screw drive allow for smaller design, different focus group (you may have to change the optical formula to adapt in lens motor) and has proven to be VERY robust. My FA ltd lenses focus fine and fast and are nearly silent in practice. No hunting no whatever. Maybe they are not the ultimate best for sports/action but that would be more for me DFA24-70 and DFA70-200 then.
I don't know what Pentax should do with them. Keeping them as they are exactly, look good to me at least while they focus on huge optical perfection of f/1.2 and f/1.4 lenses for people that buy specs and not photos (like 99% of the internet enthousiasts theses days). Maybe once they finished the rest, they can carefully update them.
Anyway, that sure that theses lenses should not be considered as the bare minimum, there lot of place for value lenses. Despite all we think here Pentax likely made much more money on 18-55, 50-200, 55-300 and 18-135 than FA31, FA85, FA600 or other exceptional lenses.
It would be quite nice to expend a bit the plastic wonder line for example. The lenses don't have to be perfect, but just "good enough", cheap and small.
Then a limited line that focus on build quality, real optical quality rather than spec sheets, small light again and finally the perfect lenses.
If you have only part of the offering, people will be limited in their choice.
I think Ricoh is aware what the FA ltd are, and there a reason K1 was presented with FA31...
