Lens Review Date: September 2, 2018 I can recommend this lens: Yes | Price: $250.00 | Rating: 8 

 
Pros: Cheap cost. Convenient focal lengths for indoor photography. Saturated colors in the photo.
Cons: Large dimensions. With an open diaphragm, the photographs are not too sharp. The lack of protection from ingress of moisture and dust) on the quality of photos is not affected). Staggering design (the quality of photos is not affected).

I like the lens. Although in the beginning he frightened me with his large size. But the fact that thanks to this lens you get good pictures, completely excuses its large size.
Focal lengths of the lens are very convenient for photographing during walks and travel. In the rooms it is also convenient to remove this lens. Just do not forget about the stationary flash. Because the aperture to this lens, for shooting in not very bright rooms, is often not enough.
When I have this lens on my camera, I always snap a stationary flash on the camera. And I photograph with a flash even in the daytime (I also include the "contrast adjustment" function on the flash).
With an open diaphragm (F4), the sharpness of the image decreases. And chromatic aberrations appear. But if you shoot at diaphragms 5,6-11. And focal lengths of 20-40mm., While using a stationary flash, the images are sharp, and the photos have beautiful and saturated colors.

Lens Review Date: June 22, 2018 I can recommend this lens: Yes | Price: $120.00 | Rating: 9 

 
Pros: Constant f4, very cheap in the used market, sharp throughout range, very pleasing images
Cons: Construction could be better - the barrel tends to wobble with time
Sharpness: 8    Aberrations: 8    Bokeh: 8    Autofocus: 9    Handling: 9    Value: 10    New or Used: Used    Camera Used: K10D, K-r, K-S1   

I have had this lens now for a couple of years, and have not been disappointed. It is a work horse, and used a lot of times for family outings, indoor pictures (works great with flash), travels, events and so on.

It is not as sharp or fast as a prime lens, nor does it render as exquisitely as they can, but in what it does, I feel it does it well, and even exceeds expectations. It is sharper than a lot of vintage lenses (especially most 3rd party lenses I have tried), and the coatings are great - always contrasty and with vivid colors, and you can even shoot into the sun, at least my copy does with hardly any problems.

It is sharp wide open except the extreme corners in my copy. There is a bit of field curvature so f4 landscapes at 16mm can be affected depending on where you focus, but from what I can tell it is still much less than other similar types of lenses. In fact the distortion is quite low and what little there is, does not feel unnatural at all. It even focuses very close as well, it's supposed to be 1:4 magnification but in my experience it's more like 1:3 at 45mm.

Better photographers than me have taken some absolutely wonderful pictures with this lens, so I feel that if you like the way it renders, there's really no need to go for the third party 17-50 2.8 models which won't give the nice Pentax colors that this lens does, along with good flare control, sharpness, very low distortion and a relatively lightweight package.

Some samples.

Lens Review Date: June 22, 2018 I can recommend this lens: Yes | Price: $160.00 | Rating: 9 

 
Pros: Cheap, good average picture quality, useful range.
Cons: Quite plastic feeling and quite long to be only 45mm.
Sharpness: 8    Aberrations: 9    Bokeh: 7    Autofocus: 9    Handling: 9    Value: 10    New or Used: Used    Camera Used: K-30   

I have not tested the lens technically, only by taking photographs and honestly it is much better than quite many reviews in here are told.
What I'm missing is a little longer long end like 70 mm.
Anyway much more useful than the 18 - 55 mm standard zoom because of the wider end.

Pros: The constant of light intensity. Quick focus. Wide angle. Non-rotating front element.
Cons: I would like even more sharpness. At 16 mm there are distortions (works well with 18-20 mm). At 45 mm sharpness is not satisfied.
Sharpness: 8    Aberrations: 8    Bokeh: 6    Autofocus: 9    Handling: 8    Value: 6    New or Used: New    Camera Used: K10D, K-70   

I took this lens to K10D as an alternative DA18-55 mm. Not quite impressed with the result. With such a modest aperture, I would like good sharpness in the entire diaphragm range. This is the main claim to the lens. In the rest, he justifies his price.

Lens Review Date: May 26, 2018 I can recommend this lens: Yes | Price: $150.00 | Rating: 9 

 
Pros: Sharp, useful range, minimum focusing distance, light
Cons: None
Sharpness: 9    Aberrations: 8    Bokeh: 8    Autofocus: 9    Handling: 9    Value: 10    New or Used: Used    Camera Used: K-10D, K-7, K-50, K-S2   

A lens from *ist years. Still quite good. Although f/4 is a bit slow, the maximum aperture is close to the optimum aperture. Sharp from corner to corner. Classic color rendering. Very useful range and minimum focusing distance.

Look for a good copy and you will not be disappointed.

Lens Review Date: July 11, 2017 I can recommend this lens: Yes | Price: $350.00 | Rating: 10 

 
Pros: Great walkaround and travel lens
Cons: Reverse behavior for somewhat noisy zoom
Sharpness: 9    Aberrations: 8    Bokeh: 7    Autofocus: 9    Handling: 9    Value: 10    New or Used: Used    Camera Used: K-r and K-5   

This is my favorite lens. I almost always get good shots, be they landscapes, portraits, or even action shots. Sharpness is found at f5.6 and tighter, but face shots at f4.0 are very nice and slightly soft with natural and tungsten lighting. I prefer this to any zoom or single lens. It's a little on the heavy side and the zoom feature works reverse to what most people expect (it contracts when zooming).

Overall, just a great build and exceptionally good glass.

Pros: useful range of focal, light, fast AF, sharp from wideopen
Cons: build feel plastic, could be a little shorter, hard to take off lens hood
Sharpness: 9    Aberrations: 10    Bokeh: 8    Autofocus: 9    Handling: 8    Value: 10    New or Used: Used    Camera Used: K-70   

I have to say i don't use this lense much ...BUT everytime I use it i take a shoot im glad with! I don't know why this lense have so poor reviews.
I haven't noticed ANY ABERRATIONS! Every! So that's weird especially in compare to the other lenses that have so much better "abberations" rates at pentaxforums/lensreviews ...but in real life they suck with chromatic aberrations ( like a Vivitar 70-210 by Tokina for example )

Im useing it for wide shoots - landscapes etc

Sharpness is very good from wide open! And it doesen't change till the end. Seriously. I wanted to post some shoots with different /f 's but almost nothing change with the sharpness so don't need to post it here

Aberration - as i said, i never noticed ANY!

Bokeh - I didn't know how to rate it - most shoots I take I Take at infinity, so there is no bokeh. I might don't even seen the bokeh of this lense

Autofocus - is fast and accurate. Never have any complaints.

Handling - well it's not a small lense, but the biggest issue is a hood. It's hard to take off. When it's mount upsidedown you can't reach focus ring! Lense doesen't feel strongly build - plastic feel weak but i've never broke anything.

Value - it's very useful lense. I guess you won't find any wider lense with af for such price. Im always have it with me no matter what

edit. i've tested the lense for sharpness and i get STUNNING effects at f11! anyway it's nice even from f4 but the f8 and f11 are kind of a breaking points

Cons: Maybe f4?, not WR
Sharpness: 9    Aberrations: 8    Bokeh: 9    Autofocus: 9    Handling: 9    Value: 10    New or Used: Used    Camera Used: k3II   

I got this lens 6 months ago and i thought it was great but now I want a zoom with more luminosity. After trying the Sigma 17-70 2.8-4.5 I have decided to keep the Pentax.

With the Pentax you get really great results at all focal lenghts and at all apertures. You also get stable results not like the Sigma which in some focal length and aperture combinations you get different results. Furthermore the Pentax results are reasonably more stable throughout the frame, not like the Sigma.

Maybe the best "standard" zoom lens out there.

New or Used: New   

Did anyone know this lens becomes a 20-45mm on the K-1 and covers the full frame with no vignetting at those focal lengths? I tried it and it does. So if you still have one this breathes new life into it and an obviates the need to go scrounging for the out of production 20-35mm, also an f/4 constant aperture lens. If I am not mistaken the 16-45mm is pretty highly regarded.

So I just saved you $500 !!

Pros: Better than 18-55 kit
Cons: Awkward handling
Sharpness: 9    Aberrations: 9    Bokeh: 8    Autofocus: 8    Handling: 5    Value: 7    New or Used: Used    Camera Used: K-30   

+ Goes waaay close even though it's not advertised as having macro capabilities: magnification ratio is 1:3 at 45mm.
+ Because of close focus ability you can have nice blurry backgrounds even though the lens isn't that fast.
+ 16mm is useful to have both for cramped indoor shots as well as landscapes.
+ Uniformly sharp at f/4.0
+ Focus ring is ok for an AF lens.
+ IQ and especially image rendering is superior to the 18-55.
+ Not that heavy.

- Feels clumsy in use, difficult to remove lens cap when the hood is on, extends very long when zoomed in.
- No WR.
- Tele is on the short side.
- Hood interferes with on-board flash casting shadows.
- Hood casts shadows if used when doing extreme close-ups.

In conclusion it's a class above the 18-55 and its close focus ability in combination with 16mm does make it easier to be creative. Worthy upgrade. Wouldn't pay more than I gave, though.

Pros: Closer than the 18-55, Fast AF, decent IQ
Cons: BIG/HEAVY vs DAL kit lenses, light/bright and soft in "auto", some purple fringing
Sharpness: 8    Aberrations: 6    Bokeh: 7    Autofocus: 9    Handling: 6    Value: 8    New or Used: Used    Camera Used: K-70   

Cons and Pros pretty much say it all...I would just keep the kit lens (depending on which one you get) as this just doesn't feel like an upgrade... I wanted the shorter throw and the DA lens, would stick with a regular DAL 18-55 if I did it again... THAT being said I haven't tested them side by side as I usually prefer - PLUS I want to try the 17-50 or 17-70 by sigma/tamron, etc... I will post if I try one of those and do not keep this lens :-)

The feather pic is stopped down to 8 (it typically stays in 4f with "auto" selected), as this yielded the best results.

Pros: Sharpness, f4, good zoom range for me.
Cons: Not WR.
Sharpness: 9    Aberrations: 9    Bokeh: 8    Autofocus: 9    Handling: 10    Value: 10    New or Used: New    Camera Used: K-3 and K20D   

This lens is a little gem. It started its life as the kit lens on the K20D, but has proved itself to be a very versatile piece of glass. It is a very sharp lens that renders colors beautifully IMO. For landscape and street photography it is excellent. The only shortcoming of this lens is the lack of weather sealing. Everything else is above average. I can highly recommend this lens.

Pros: Colors, Sharpness, Wide Angle
Cons: Not long enough sometimes
Sharpness: 9    Aberrations: 9    Bokeh: 9    Autofocus: 9    Handling: 9    Value: 8    New or Used: Used    Camera Used: K3   

Very versatile lens. On my K3 this is quite sharp from f5.6 on, and very decent at f4.

Shot below is a 2/3 crop of Caesar in Vegas


This one is of a fountain with a lot of detail. Obviously the un-resized picture has greater detail. But the colors here are great.

And lastly Caesar's Palace. Again, the un-resized picture has more detail.
