Try lenses from Canikon and you will see that all three lenses have very average AF (like all Pentax set up). They are all semi MF lenses.
That isn't the lens, AF is the camera. Geez. None are semi-MF lenses. If you like Canikon so much then use those but don't come in and say this one has AF problems and is "semi-MF" when that's just simply untrue.

Sory, I didnt mean to hurt your feeling about Pentax AF, but the true is that I was Pentax user for 10 years and now I am Canon user (for one year) and the difference in AF is really big.
Yes the AF is camera and not lens, but Sigma HSM works better than Pentax SDM on the same body. SDM is much slower. Not to speak about sound of screw drive from Pentax. It can be really annoying.

(just nitpicking) :
Try a Canon 50/2.
No way a Pentax lens can do more noise than that one.

DA 35/2.4 instead of FA 35/2, DA 50/1.8 instead FA 50/1.7. What's next - DA 28/3.2, DA 135/3.5?

Yes, Nikon cameras do automatically crop to APS-C when a DX lens is attached. I can't speak for 3rd party lenses, but I suspect they would be the same.
You can turn the auto-crop off, though.

These lenses are already exist. I do not see any idea to re-badge them.
I'm talking about future (or forecoming?) lenses in DA L category, based on true past F/FA. I.e., we have FA20/2.8, A24/2.8 , FA28/2.8, FA 135/2.8 or M 135/3.5 fixes. These small lenses with good focus length and optical quality could be re-badged in DA L version - portable and light, even with 1/3 stop slower. We also already have those 'juniors' FAJ 18-35, 28-80 and 75-300 in production to fullfill the line of cheap plastic FF.

It is $100 less than the FA50/1.4 (about the same as a used FA), but one gives up FF capability, an aperture ring and a good deal of speed. It is also four times the cost of an A 50 of similar speed. My FA50/1.4 performs superbly on my DSLRs and film SLRs. I can look at a set of photos and pick its result out immediately. With this DA lens, you give up both backward and forward compatibility. I'm having a tougher time "getting" this one, than, say the DA 35/2.4.

There are soooo many 50mm prime options. I own 4, and I'm not even much of a lens hoarder. I suppose if you are just starting with APS-C and need to scrimp and/or keep the same filter size as the kit lens (but not the DA 35) or just like this particular rendering.

Retailers have described the lens as FF. Pentax never has officially announced that it is FF compatible, but until someone shows me severe vignetting I'll assume it is compatible.

One thing I don't like about the FA 50 f/1.4 is the hexagon bokeh in certain cases. I don't know if the DA 50 F/1.8 is an improvement or not in that case, but the specs suggest it would be.

The bokeh in the examples linked from the other thread was not more pleasing to my eyes than that I get from the FA, but YMMV. For me, that wouldn't outweigh losing a stop and compatibility with my dear friends MX and LX, as well as 35 years of filters.

I tend to assume the opposite from the "DA" designation, and I am gratified when I find that assumption to be incorrect. For example, the DA 55-300 was a big, positive surprise on a film body. I'll be interested to see what happens when someone tries this lens on film.

Have you ever shot 'small points of light' with the FA? I get either hexagons or outlined blobs of light, neither of which are beautiful, IMO. I'd much prefer a few extra, rounded, blades.

That said I'm not running to go buy a DA 50mm F/1.8. If I get anything it'd be the 55mm, but the SDM, the cost, and the weight keep me away from it. When I get the Pentax FF I might revisit that decision.

I owned the FA 50 and didn't like it. The DA 50 is a half stop slower, but otherwise, I don't see that much difference. Build quality isn't that great on the FA 50, sharpness isn't that great on the FA 50 below f2.8, either. The FA 50 doesn't even have quick shift or, a lens hood with it. As far as I know, the DA 50 is full frame compatible, so for the 100 dollars the only difference is the half stop.

Edit: Let me be clear. If you are satisfied with the FA 50, I think you would probably be satisfied with the DA 50. I wasn't satisfied with the FA 50 and doubt I would be with the DA 50 either. I ended up getting the DA *55 which, to me, has nicer bokeh, is sharper at similar apertures and has nicer colors and micro contrast. Just my two cents.

I can't compare it to the DA* 55, but the FA 50 compares well to the other 50s I've owned over 4 decades, even one from a famous German maker. Perhaps I would love the DA* 55 so much that all others would pale; I don't know. Not working on my favorite film bodies was kind of a nonstarter. However, I couldn't be much happier with the FA 50. I'm even OK with the plastic body.
