Pentax 50mm f/1.4 SMC P-FA User Reviews
9 out of 10 points and recommended by kiwijono (7 reviews)Small, very sharp stopped down, fast, full frame, very good valueLow contrast at f1.4, bokeh can be a little nervous wide open sometimes
IMO this lens really comes alive on the K-1. The focal length is now a perfect "normal" lens and very general purpose. Yes it can look a bit soft wide open but this is mostly low contrast (although sharpness is not that great either).reviewed December 10th, 2016 (purchased for $200)
Its size is very compact for the speed and is very easy to carry around. I have found on my K-5 the bokeh can sometimes be a little nervous wide open but much better at f2. Not sure if this will change on the K-1 yet but first test shots look promising (possibly because focus distances are nearer for same subjects).

For portraits optimalreviewed January 31st, 2014 (purchased for $100)
I use it for astronomic photography, too.
colors, contrast and sharpness very nice.
Best sharpness on f4. My best lens - besides excellent PENTAX lenses as 1.8/50 DA and 2.4/35 DA.
Excellent results with 7/5-elements-tele converter with aperture cosed to f 4 - f 5.6.
9 out of 10 points and recommended by shatz (2 reviews)from 1.8 sharp, from 2.4 really sharp, solid constructed, fast AFsoft and CA at 1.4, not WR
I bought this lens for my K5II for portrait shots, its really usable in all aspects, even at 1.4 the images are good, contrast is a bit low and it cut look like it is a bit foggy, can be put in use greatly! betweens F2 and 8 pictures are really sharp, rich in contrast and all in all really good! if you dont have one, get one, its always a usefull lens!reviewed January 28th, 2014 (purchased for $250)
9 out of 10 points and recommended by Tord (30 reviews)Fast, cheap, and compactVery tiny focus ring
This is quite like the Pentax 50 I had 40 years ago, but it is optimized for a modern camera, and has autofocus, and an aperature ring, so you can set the aperature manually, if you want (excellent for 'dumb' extension tubes).reviewed September 5th, 2010
Slightly bigger than the Pentax pancakes, it has excellent sharpness and is faster than any Pentax pancake (to date).
I use it mostly reversed, for macro phtography, but it works well as a short tele as well!
9 out of 10 points and recommended by phoxhill (2 reviews)Very sharp from f/4 to f/8 / ideal for protraits / cheapsoft wide open
A very usefull small telephoto, sharp with a wonderfull bokeh.reviewed February 20th, 2009 (purchased for $262)
Ideal for portraits but also flowers...
Even sports if you're close enough to the action
My best lens up to now!

This is a top quality and rather cheap lens alternative to the highest quality and expensive lenses from the Pentax brand. I often use it as a all round lens under any situations; from the poor light indoor, in the sharp sunlight and in the portrait studio. Seereviewed September 1st, 2008
with images taken with this superb lens! At it's best stopped down to 8 or 11.
I also have the Pentax SMC F 50 mm 1.4 (discontinued from production years ago)....
...and I tell You; it´s even better!!!! :o) Rob
8 out of 10 points and recommended by grim grimsson (6 reviews)Cheap,Soft wide open
This lens is reasonably sharp from f2.8, but at wide open it is a bit soft. It is cheap, and for the price it is a good lens. If the extra cost is no issue, I prefer the 40mm limited lens, which is better in any aspect.reviewed June 30th, 2008 (purchased for $300)
9 out of 10 points and recommended by joekashi (7 reviews)Small, very sharp, cheap, good short portrait or tele lens, very compact and lightNone
Build quality is more than adequate. This lens is a very nice addition to a Pentax bag. It's certainly a lot faster than the kit lens and also quite a bit sharper by F4.reviewed January 26th, 2008 (purchased for $194)
9 out of 10 points and recommended by amonsul (1 reviews)fast, resolution, bokeh, cheapcorner softness wide open
Nice lens. Some weakness if you use it wide open, but at medium apertures the lens is superb.reviewed August 15th, 2007 (purchased for $200)
9 out of 10 points and recommended by wavefunc (5 reviews)Excellent image quality, very fast aperture, great bokeh, small and light for the qualityNone that I've noticed, except that it's hard to find it in stock!
This was my first purchase after the 18-55 kit lens, and I was looking for a sharp lens with a bright aperture for low-light indoors stuff. This has fit those criterea well. Stopped down a couple stops it's about as sharp as you can get, and even wide open it's still not bad at all. The bokeh is very smooth and pleasing too.reviewed February 4th, 2007 (purchased for $230)
If a 50mm is indeed what you want (it's more of a portrait lens / short telephoto for digital) then you can't go wrong with this lens. Personally, I think I would have made use of a 30mm more, but when I can use a 50, this is ideal.
10 out of 10 points and recommended by mjbamigo (4 reviews)Contrast, Color, and Sharpnessslow focus for a prime, weird, plasticy body
This was an upgrade from my 15-55 kit lens. It is absolutely worth it. I miss the wide range, 50mm on a cropping DSLR makes it a right-up-in-your-face view on most things. Now that I'm been shooting with this, I think I'll start saving for a wider Pentax prime.reviewed January 14th, 2007
But I had no idea my *istDS could get such results. The pictures are sharp and contrasty. It's bright; the pictures, and even the viewfinder are much more light than with the 18-55mm. The photos seem to glow.
highly recommended.... (also consider one of Pentax's older versions. I have a beautiful 50mm f1.7 that also gets very nice results. Pentax, though, seems to have a tradition of building these things in a strange, plastic casing..)
9 out of 10 points and recommended by nighthunter64 (5 reviews)Cheap, great opening, very sharp image.none so far
- Great for low light pictures.reviewed January 12th, 2007 (purchased for $219)
- a little bit above average for built quality coz plastic feeling but its just a feeling great image quality!!!
8 out of 10 points and recommended by dppa (3 reviews)Scharp, nice bokeh (but not great)lose manual focus ring
This is a very fine lens. A bit soft wide open, especialy in the corners, but stoped down (past f3.5) it's extremely sharp. On a digital SLR is becomes a nice portrait lens.reviewed December 23rd, 2006 (purchased for $223)
De manual focusring on my sample is a bit lose and less damped than the manual focus lenses (K, M, A)
9 out of 10 points and recommended by kjao (1 reviews)good bokeh, sharp imagenone
FA50mm/f1.4 is one of my best lenses. It is a just a little soft wide open but very good for portraits (when used on DSLR). Stopped down one or two stops, the images are tack sharp!reviewed February 4th, 2006 (purchased for $220)
Physically, it is quite small but dense than it looks. Built quality is very good, plastic body with metal mount. Manual focus ring is very smooth but not as good to use as Pentax's old A and M series.
