Stumbled across this lens and used the feedback of this forum to purchase this lens. Love the focal length and IQ for portraits even wide open at F2.8. To me, not an everyday lens but, I can see me using for specific events.

Lens Review Date: July 22, 2014 I can recommend this lens: Yes | Price: N/A | Rating: 10 

 
Pros: IQ, AF, Close Focus, Metal Construction, Size
Cons: CA, noisy AF.
Sharpness: 10    Aberrations: 8    Bokeh: 10    Autofocus: 10    Handling: 10    Value: 9    Camera Used: Pentax K-5iis   

I'm a huge Pentax F series fan, over the years i've collected some nice F-series primes. I've had always wanted the 135mm f2.8 and after a year of unproductive auction attempts I finally won one. I bought this lens in rough condition, I knew I'd never sell it, front element has scratches, marks and few chips but you wouldn't notice such issues from the amazing images it produces.. This lens arrived the same day as my much awaited and obscenely expensive Sigma EX DG 300mm f2.8. It took both lenses for an outing and although i shot with the sigma for over an hour on the way to my car i decided to give the Pentax a chance. I started with some flowers and i was amazed at the creamy, macro like bokeh it produced. Taking some pictures of Mallard ducks i noticed I was getting amazingly sharp pictures. The lens nails focus with its aggressive, loud screw drive operation. Although i expected the Sigma 300mm f2.8 to be the outstanding performer, the little Pentax performed flawlessly stealing the Sigma's thunder.

Autofocus on the Pentax was far more reliable then on the Sigma. CA was an issue on bright spots such as water droplets even at smaller apertures.

One reviewer complained about size and weight, but considering that this lens is as long (but marginally heavier) as the 18-55mm kit lens and doesn't extent i could not think of a better walk around short telephoto. People are intimidated when they see the Sigma EX 300mm f2.8, but the 135mm is so unassuming that I found it easier to take candid pictures without being overly noticed. I like the reach of the 135mm on a crop sensor, and with the K-5iis i can crop and still get good results,

The close focus distance is also very convenient. You can shoot portraits wide open from a couple of feet away with amazing bokeh and subject sepraration. This is a speed/bokeh monster without equal. This lens will stay by my side and when my Pentax DSLR is gone I'll still keep it as a souvenir. If Pentax were to make a modern version of this lens with HD coating and better CA control i'll buy it in a heartbeat. Highly Recommended 10/10


Buying advice: These lenses are sturdy, all metal construction. Dont be dismayed by scratches and small imperfections. As long as the optics are moderately clean this little gem will outlast your DSLR.

Lens Review Date: May 4, 2014 I can recommend this lens: Yes | Price: N/A | Rating: 10 

 
Pros: Stunning sharpness fast and accurate AF Brilliant colours
Cons: rarity perhaps CA but PP sorts that out fast
Sharpness: 10    Aberrations: 9    Bokeh: 9    Autofocus: 10    Handling: 10    Value: 10    Camera Used: K30   

This is a rare beauty.

I managed to stumble across one for I price that I cannot share. If I did it would cause a riot

The reach is simply amazing on a cropped sensor (200mm). Add a 1.5X teleconverter and you get even more reach with almost NO IQ loss (Kenko Teleconverter 1.5X DG - another rare beauty).

It is on the heavy side but I like that. Balances well with the camera and actually improves handling.

Colours are very fine indeed. Contrast is excellent. Sharpness compelling. A little CA but that disappears the moment you wave Photoshop near it

I'll let the photos exhibit the genius this lens is

Pros: Autofocus, bokeh and sharpness at f2.8, manufacturing
Cons: Aberrations, vignetting at wider apertures
Sharpness: 9    Aberrations: 7    Bokeh: 9    Autofocus: 10    Handling: 10    Value: 10    Camera Used: K5   

Excellent 135mm, focal length is really interesting for the portrait.
The results are truly amazing at f/2.8 although under certain conditions chromatic aberrations are present. Past f/4 is really impeccable and sharpness is amazing. The construction of the lens is magic, metal is really something other than plastic !
But the pictures speak louder than words ...

Bokeh at f2.8


Sharpness at f4

Pros: Size, sharpness colors, generally good bokeh
Cons: Bad PF at wider apertures
Sharpness: 9    Aberrations: 7    Bokeh: 9    Autofocus: 9    Handling: 10    Value: 8    Camera Used: Pentax K-r   

I haven't had this lens too long but figured I can contribute some here.

First, the one main negative of this lens is purple fringing. Pretty much at f/2.8-4.5 if you have branches, fence posts, any other thin object in front of a bright sky, you're gonna get PF. I haven't really come up with a successful way to fully remove this in post. I have successfully fixed some less-pronounced PF in other parts of images.

Now, the good: this lens is really great at medium distance portraits where your subject is close enough that you're not approaching infinity. Then it's nice and sharp but gives you good separation from background. These were all at f/4 (and hey, no fringing!)









Other aspects: it's pretty much all metal best I can tell. Has a nice little built-in hood that slides out. AF is quick without much hunting. It's not nearly as loud as my F 70-210/4-5.6 but it's louder than my small primes (DA35/2.4 & FA50/1.4) which I suppose is to be expected since the focus group on this lens probably weighs more. MF is kind of loose and the focus ring isn't very big but this is common for (perhaps too) many AF lenses.

Pros: fast and accurate focus, build quality, f/2.8, great image quality
Cons: none (slightly noisy focus does not bother me at all)
Sharpness: 10    Aberrations: 10    Bokeh: 10    Autofocus: 10    Handling: 10    Value: 10    Camera Used: K-5   

I have been looking for an excellent lens for the portrait photography. I have tried Sigma 85mm f/1.4, but its inconsistent auto focus made me return the lens. I know that 135mm on crop camera would be a little long for portrait, but to me it is not a real problem, I may step back several meters. But instead, I would have nicer bokeh with this focal length.
I am so amazed at its fast auto focus. It is as fast as my Sigma 50mm HSM prime. And the most important thing here is that it focus very accurately.
So far I am very happy with its performance. It was lucky that I got this lens from ebay for only about $545, great deal.

Pros: quick AF, IQ, DOF control, build quality, internal focus
Cons: small amount of PF

This is simply an amazing lens. Super compact, auto focus is as quick as many say, build quality is excellent. The internal focus is nice, as the lens always stays the same size. It's a lot of fun to shoot with, and I've gotten many images I love with it in a short time.

Pros: Sharp, smooth bokeh and fast AF
Cons: Slightly noisy AF, PF

IMO this lens is comparable to my FA limiteds, the FA77 and the FA43, except the pixie dust of the limiteds. Also, it is not as fast as them. I'll just post some images.

Pros: f2.8, contrasty and sparp
Cons: large and heavy

Another I saved from the dumpster at work. I have used it in all sorts of situations where I thought 135mm would be too long but the f2.8 makes it worth carting around.

Pros: IQ, build, focus speed
Cons: none

This is a wonderful lens. I use it wide open with no hesitation, it is sharp and contrasty. I have had the lens for almost a year, and have still not seen CA/PF, not even at 2.8.

AF is very fast and precise, but a bit noisy. The lens is built like a tank, all metal exept for the focus ring.

The only reason for not giving it a 10 is that OOF highlights could be rendered slightly better/smoother.

I believe it is optically identical to the FA version, so this review goes for that one too.

Pros: sharp wide open, solid construction
Cons: suffers from a little CA wide open

This is a gem of a lens. If you come across one, buy it. It focuses very well, and the built in hood is handy for outdoor shooting. I'm continually impressed with it every time I use it.
