Description:
The SMC Pentax-FA 50mm F1.4 is a film-era 50mm lens with a very long production run. It was introduced in 1991 and not discountinued until 2023. It has an aperture ring and is therefore fully compatible with all Pentax DSLRs as well as film bodies.

It was replaced with the Pentax-D FA* 50mm F1.4 designed specifically for digital cameras with a full frame high-resolution sensor. APS-C shooters have the Pentax-DA* 55mm F1.4 as an alternative.

There really isn't much more to say.

A real contender for best 50mm ever.

Pros: Natural rendering, bokeh, fast, sharp
Cons: AF problems, cyan fringing, warm cast

From f/2.8 this lens is very sharp with very high contrast and smooth bokeh. Results can be spectacular.

Dreadful contrast and soft below f2.8 but real achilles heel is cyan and magenta fringing which is particularly evident in OOF areas. AF under incandescant light is infuriating.

Since acquiring the 77/1.8 I find the 50mm focal length a little too short for individual portraits and too long for two person portraits so I have replaced it with the FA35.

Pros: Excellent sharpness and OOF rendering
Cons: Build could be more solid?

This is an excellent lens usable wide open, razor sharp stopped down. Creamy bokeh. Good focal length for portraits.
Build doesn't feel to solid, but it is not a problem (I am comparing to SMC Pentax K and the Limiteds here

Pros: Edge-to-edge sharpness, bright
Cons: None

I've used many 50mm lenses for 35mm and digital SLRs and I can honestly say this is the best 50mm f/1.4 lens I've used for any camera.

There is no better 50mm f/1.4 lens.

'Nuff said.

Pros: price
Cons: plastic, soft wide open

I will say more or less the same. Soft wide open. Quite sharp from 2.8.

Overall must to have for all pentax users.

Pros: The best 50mm every produced by Pentax
Cons: none

As other reviewers have stated, "Soft wide open"? I guess. But if you don't want to use a flash in interior low-light situations, there is not much choice, and I do shoot wide open often with this lens. Images are quite acceptable to me, but maybe my standards are a little lower.

I won't add anything to the other reviews, as they've covered it pretty well, but will say...

If you can find a new copy of this lens . . . purchase it immediately! They are becoming more and more difficult to purchase new. You will not be disappointed!

Pros: Tack sharp lens.
Cons: None that I can think of.

As others have stated, this lens is best when it's stopped down a little (like most lenses). Considering it's average price, it's a fantastic bargain. Even at a higher price, this would be a winner.


My favorite lens.

Pros: Sharp a stop down, small, quick AF, low price
Cons: bit prone to PF/CA when near wide open

A stop down it is very sharp.. The lens is small and handy, good for portraits with its 75mm equiv FOV..

Only problem I have with this lens is it has pretty bad PF when wide open or near enough... Though I tend to only use it less than f2.8 in dark environments so it doesn't often exhibit this flaw..

The manual focus feel of this lens isn't so nice after having owned an A series version, though if you mostly use AF its not an issue ;-)

Pros: Excellent image quality once stopped down past f2
Cons: A little soft wide open
Sharpness: 9    Aberrations: 9    Bokeh: 9    Autofocus: 9    Handling: 9    Value: 9   

Once stopped down, the FA50mm f1.4 has excellent sharpness. Bokeh is also excellent as is colour rendition.

Wide open it is a little soft and lacks a little contrast, but sharpens up nicley at about f2 or more.
