Portrait lens.
The "traditional" portrait length for 35mm was an 85mm lens and all of the Pentax offerings at that length are superb, as is the FA 77mm Ltd. One alternative is the slightly longer SMC Pentax-M (or -A) 100mm f/2.8. These were, however, designed for film cameras and are probably a bit long for APS-C. The DA* 55mm seems to be the intended replacement lens and has a good reputation. If you want a modern autofocus lens, the DA* 50-135mm f/2.8 is excellent choice which also gives some flexibility. Not the fastest AF in the world, but gorgeous image quality.

Lots of film bodies, a couple of digital ones, too many lenses (mainly older glass) and a Horseman LE 5x4.

Pricewise - DA50 f1.8 is a good portrait, followed by the FA50....
Quality wise 55 and 77 are stellar...ultimate portrait lens is of course the FA*85...

Hi all,
I would like some suggestions on what are some good portrait lenses with good quality sharp images.
Thanks.
I'd've thunk your 90mm tamron would do a pretty sterling job???
Is it too long? Maybe look at a fast-50-ish offering (M/A/F/FA50 1.4 or DA50 1.8 or DA*55 1.4 or even DA70Ltd are all shorter) or maybe even a 35mm (FA's 31Ltd or 35-f2 or DA35-2.4)...
There's lots of suggestions but unsure of your usage or budget...

If cost is not a consideration then the DA* 55 f1.4 is the current Portrait offering from Pentax (as said earlier in the chain - the replacement for the FA*85) and has the advantage of being a digitally optimised, weather-resistant, SDM (advantage?) powered lens

Hope that helps

“We must avoid however, snapping away, shooting quickly and without thought, overloading ourselves with unnecessary images that clutter our memory and diminish the clarity of the whole.” - Henri Cartier-Bresson -
But if you want a very fast prime, then the 77mm Limited, Sigma 85mm F1.4 or DA*55mm. Also the Manual 55mm F1.8 in various guises is a cracker!
For zooms, the default choice for me is the DA*50-135mm - an Outstanding lens for studio work.
For full length shots, The DA35mm F2.4 is a little gem, and cheap too.
Hope this helps

Star, you already have a great portrait lens in your collection, namely the Tamron 90mm Macro.
Isn't this going to be way too sharp for a portrait lens?
It'll surely show every pore, skin blemishes, and facial hair.
It may well be a suitable focal length, but I think that too much post-processing would be needed to soften the pin sharp images.
Portrait lenses are normally designed to be somewhat soft wide open, as is the FA 77mm Ltd lens and I believe, the FA* 85mm.
I don't do portraits, so I may be completely wrong.

weather with filters or other techniques, or photoshop it is always easier to make a sharp lens look soft than the other way around..

may fav lens for digital portraits is the Pentax 100 mm macro..followed by the 50 1.4 then the 16-45
Fired many shots. Didn't kill anything.
looking.

I used to hate using a 135mm on film anything bigger than
a postcard print looked terrible.

A general rule of thumb with prints from 35mm is that they
should be viewed from the same distance that they were
taken to show the proper perspective.... that's about 6ft
for a 10"x8" print.... It would be more for APS-C

I would use a 50mm/55mm.

I just got a Carl Zeiss 35mm F2.4 Flektogon the other week and i find it to be a wonderful portrait lens , but saying that you can pick up a lot of manual lenses that will do the job , like i say its what your willing to pay , I don't mind using manual lenses especially for portraits , its not like there going to run away lol
If you do prints from a 100mm lens Don, isn't it very flat
looking.

I love the 100... and no they don't look flat...

I find my 100mm macro a joy for portraits...
