hmmm...maybe you had a bad copy? Mine is tack sharp at 2.0-2.8 and up. I don't really shoot a lot of things needing a 1.4...unless really low light, but that's not that often. Portriats most likely wont be shot at 1.4-1.8 anyway...

Maybe I am lucky with my copy?

My experience with the FA50/1.4 is it is starting to look like it will get sharp at f/2. but isn't really sharp until f/4 (there is a huge improvement in sharpness from 1.4 to 2).
However, this only describes one parameter of the lens. I'm finding the DA55/1.4 has much more exquisite rendering abilities than the 50/1.4.
It's a bit hard to describe, but detail rendering on the 55/1.4 seems sharper, but at the same time less harsh, like as is it is is making smoother tonal transitions.
In a way, it reminds me of the difference in look between a picture shot on 35mm film and one shot on medium format film.
In short, the FA50/1.4 is not a cheap replacement for the 55/1.4. The 55 makes the 50 look like a cheap lens on many levels.

How often would you shoot a portrait at anything less than 4.0? 5.6? I would love to see the exif info on the shots in this thread.

The examples of this lens are very nice, I am not knocking it at all...just think the FA50 is a fine lens, and just as fine as before the DA55 was released.

Anyway. price comparison wise...I think I'll keep my FA.

Good for you. No one if forcing you to buy one.
I do wonder what the purpose of your post is though.

I tried the 55 in a store along with other da* like 50-135 and 60-250 and it was my impression that it was very slow to focus, the 60-250 was very fast, it was like *ziip* vs the 55's *ZIiiiiiiiiiiiiiiiiiP* maybe its just me... I found it surprising because I thought normally large aperture lenses focus faster and this being a da* lens.

Hmm...very strange, cuz I found the 55 to be pretty dead on for locking and not as slow as some make it out to be. If anything, it was maybe a smidge slower than my DA*50-135 (and this was in a dark store too). But most importantly for me, the autofocus accuracy was like my DA*50-135 - very good even in dark areas. Heck, these DA* lenses seem to be able to find focus even when it's too dark for my eyes to manual focus!

I'll double check this, but when I tested the DA*55 I had to think really hard about the speed of the AF cuz I didn't notice it being slow. And if AF fails, this lens is still awesome to manual focus with.

...

For me, the purpose of getting a prime DA*55 F1.4 would be the ability to blur the background more by adjusting aperture instead of zooming in (for me, that means going below F2.8 at times when I'm stuck at F2.8). With my DA*50-135, I have to zoom to a longer focal length to get the background to blur. The problem with this is that zooming compresses my image when I may not want it to.

Also, the weather sealing (for rainy/snowy days), the SDM (for autofocus), the manual focus feel and the very sharp and usable F1.4 make it very attractive, even at it's price point. I was initially skeptical about this lens but after trying it out, I'm quite impressed.

...

I just went for a walk with my dad's old SMC Takumar 55mm F2 and found out that: (a) 55mm is definitely a natural focal length for me. More so than 50mm. (b) Takumars are awesome!! (c) The ability to go wide open beyond F2.8 is an asset for me and my style development.

As much as I like my Dad's Takumar lens, I think I'd probably still grab the DA*55 for the various reasons noted above.

Folks, I suggest you stop and take a closer look at these 'snapshots', and the
shots from wheatfield, as they're showing me some IQ I haven't seen yet in a
Pentax 50mm. The level of resolution is astounding at these apertures, (and note
that the ISO is very high, so keep that in mind.)

I think I saw some larger images in another thread from TKH also.

This is a pretty impressive lens...
