Seriously though, can you imagine the little -F 135 all metal, with round blades and modern coating, how good would that lens be. I'm all for updating every prime F/FA/FA* except the Ltds....
I'm personally not a big fan of the "one eye in focus" portrait photography that the modern f1.4 lenses like the Sigma and Samyang can produce. I'm not saying you cannot achive such effects with older glass heck my 30 yr old 8-element super takumar can match the EX 50mm f1.4 both in sharpness and aberration) but I just don't see the point of a ultra sharp f1.4 lens (what am I to do with the rest of the aperture stops?)
Yeah for me the ltd should be last and I think the F135 would work just fine on the FF maybe except the chromatic aberations. But I had to get it used on ebay and this didn't give Pentax any money.
That do not concern me much for intended use in all honestly and there nothing better anyway in term of size/weight/price/sharpness compromize I could get. If there a great modern DFA135, it will be more like 800-1000€ while I paid mine 318€ shipping included.
But I mean FF wise, the longest tele prime we have is DFA100 macro... Not that long tele if you ask me APSC wise is equivalent of 66mm. Using all the time my 77 I pretty well know it is a bit short sometime. I feel like there would be a need for 135mm lense in the line up again
As for being sharp at f/1.4 I don't know honestly why even f/1.4 in the first place, in particular on FF, that not a big priority for me... I understand very large apperture do help isolate big subjects like a full body portrait or a small boat.
Look at the following shoot... Was FA77 at f/2.8. I tried at f/1.8 or f/2 I don't remember but prefered the better colors/rendering I go at f/2.8. But I wonder, what if one could isolate the boat with lot of background blur and keep highly constrasty and colorfull shoot ? I think that could be fun...
And well if you want 1 eye in focus, I'am not after that I all but when I see such shoot, I tend to prefer them if the thing in focus is really sharp/colorfull/crispy. It help the effect.
But me ? Buying a huge/heavy f/1.4 lense ? Not at all what I'am after. Quite unlikely for now. If I need wide appertures this would have to be with FA77 f/1.8
