The SMC Pentax-DA 18-135mm F3.5-5.6 ED AL [IF] DC WR is a new prosumer walkaround lens from Pentax. The lens currently has an MSRP of $499.95.

This lens covers a wide zoom range and features Pentax's latest lens technology, including the Quick-Shift focus system, SP (Super Protect) coating, and a DC motor for the SDM focusing system. When this lens auto-focuses, the external focusing ring does not move, allowing for comfortable holding and fine manual adjustment on the fly as well as for excellent AF speed. The lens also features an aspherical element, internal focusing, and extra-low dispersion element, and weather sealing to compliment the weather sealing of the K-5. The aperture blades are rounded to help render a very smooth bokeh. Finally, the lens hood also features a filter window for easy use of CPL filters.

Note: this lens uses the KAF3 mount. Autofocus will only work on SDM-enabled bodies: The K100D Super and K10D (w/ 1.30 firmware or higher) and newer.

Lens Review Date: January 12, 2017 I can recommend this lens: Yes | Price: N/A | Rating: 9 

Pros: Sharp, bold colours, good AF, WR, hugely versatile
Cons: Corner IQ not great wide open.
Sharpness: 8    Aberrations: 7    Bokeh: 8    Autofocus: 9    Handling: 10    Value: 9    New or Used: New   

The strengths of this lens are: its compactness, the best AF on any Pentax lens I've had by a country mile, and WR. But beyond that, it's weaknesses are also very manageable.

My copy is properly sharp; unless your subject demands corner sharpness at the extremes of the focal range, especially at wider apertures. I find the colours bold but realistic, the contrast is excellent, and I can't remember having seen any flare. The bokeh isn't quite like a limited, but its perfectly fine. Distortion can get a bit wonky wide, closeup or tall buildings etc, but its a superzoom so it would be surprising if it did't.

If you look at any of the individual aspects of this lens' performance, maybe apart from its handling, it isn't really mindblowingly good. really is actually 'quite' good in so many ways, that when you put the whole lot together, you end up with something that is really mindblowingly useful.

Some reviews have focused on the individual characteristics and come to a negative conclusion, but in practical use, most users seem to be very happy with it, myself included. When walking around, I tend to set it to f8, adjusting only for shots which need it, and I get really super sharp results across the frame, from about 20mm to 100mm. Consistently. At 18mm it is still very useable, especially at f10 but you just start to see the corners lose it a tiny bit.

Haven't tried the 16-85, but its becoming easier to pick this lens up little a bit cheaper, and as a go anywhere do anything lens it becomes a must have I reckon.

Lens Review Date: November 13, 2016 I can recommend this lens: Yes | Price: $350.00 | Rating: 9 

Pros: Sharp, very flexible, light, waterproof
Cons: It is a zoom??
Sharpness: 9    Aberrations: 8    Bokeh: 8    Autofocus: 10    Handling: 10    Value: 9    New or Used: New    Camera Used: K5iiS   

I like this lens. I mean, I really like this lens.

I didn't expect to as I don't usually have a lot of use for zooms, preferring the greater IQ capable from a prime. And even after having used this lens for awhile I still prefer primes. They are almost always smaller, lighter, faster, with better IQ. But I will keep this lens in spite of this.

I really, really like this lens!

For starters, it is waterproof, and that was really the entire reason for buying it. So far it has not let me down on that front. But that isn't really why I like this lens so much.

I mean, it is pretty light, it handles nicely, and it is quite flexible due to the zoom range.But again, all that is nice but it isn't why I really like this lens.

It is sharp, even to the corners in my opinion. It just happens to be amazingly sharp in the center. It has low distortion. But that still is not the reason I like this lens.

Have I mentioned that I really like this lens? Well...I do.

So why do I like this lens so much. Because it is FAST!!! It focuses fast. It doesn't hunt around to find the correct focus, and that makes it even faster.

This will sound a bit weird to a lot of you, but I prefer manual focus because I am almost always faster and more accurate than auto focus. But not with this lens. I press the AF button and it is there...right now! Even if the subject is moving I can still maintain focus in almost all situations.

If Pentax is going to build all their lenses like this I may finally sell off my Canon equipment.

THAT is why I really like this lens!!! The rest is nice and is icing on the cake. But If it did not focus so quickly it would have been sold a long time ago.

Remember? I don't like zoom lenses.

Lens Review Date: November 5, 2016 I can recommend this lens: Yes | Price: $230.00 | Rating: 9 

Pros: versatile focal length, fast AF
Cons: CA is kinda bad sometimes, no infinite focus mark on focus ring
Sharpness: 8    Aberrations: 7    Bokeh: 7    Autofocus: 10    Handling: 10    Value: 10    New or Used: Used    Camera Used: K3   

Great lens, especially if you are a beginner or you want a WR kit. This lens is very nice overall, and I'll recommend it if you are looking for a cheaper, but good quality lens that is WR. I've used it for astrophotography, landscapes, and portraits, and it's never let me down.

Lens Review Date: October 4, 2016 I can recommend this lens: Yes | Price: N/A | Rating: 7 

Pros: WR, Handling, Reasonable IQ for range
Cons: Soft here and there, slow
Sharpness: 7    Aberrations: 7    Bokeh: 6    Autofocus: 9    Handling: 9    Value: 6    New or Used: New    Camera Used: K-50, K3II   

I don't believe in rating a lens based on its price, or its competition, or what you would expect...otherwise if a poor lens is a '9' because it is cheap and a good lens is a '7' because it is expensive and xyz lens is cheaper, ratings can't be compared.

So, to the 18-135... I got mine included as a kit for a bit more than the standard 18-55. I'm glad I chose the 18-135, it is a good amateur kit lens upgrade, but I wouldn't purchase it now, and certainly not at the standalone retail price. I have kept it in my drawer because it is WR, and none of my other lenses are, but that is the only reason....and it still barely gets used, only for family shots when it is wet out.

It is fairly sharp in the middle of the frame in the middle of the range and at narrower apertures. But it is soft at the corners, at the long and wide ends and 'wide open' (as much as it ever is wide). Because of this it is quite limiting if you desire easy bokeh, want to use it in low light, or use it for anything where edge sharpness matters.

On the plus side, autofocus is excellent...nearly silent, but without the SDM worries, very fast and fairly accurate with very little hunting. It has quick shift, which is great, and overall it handles well although maybe the focus ring could be a bit wider if you tend to manual focus much. It is small for its range, and light.

Overall, a great upgraded kit lens, but still a kit lens nonetheless. If you want absolute IQ, look elsewhere, but if you're looking for an all-round WR kit lens for general purpose photography or where weight is a factor, it is worth the extra on a kit.

Lens Review Date: October 3, 2016 I can recommend this lens: Yes | Price: N/A | Rating: 10 

Pros: compact, rugged, very versatile zoom range, very sharp in the center, fast and silent AFAF
Cons: corner weakness at the long end and also when fully open at 18
Sharpness: 8    Aberrations: 8    Bokeh: 9    Autofocus: 10    Handling: 10    Value: 10    New or Used: New    Camera Used: K3 and K30   

Got this lens bundled with K30 30 months ago, and it has been my most used lens since.
Works fine on K30, works better on K3, thanks to its much improved AF.

This lens must be rated as regards to what it has been designed for: a compact and rugged do-everything super zoom.

Dont expect the optical performance of a DA limited prime: I have DA15, DA21, DA35macro, DA40 and DA70, and also DA35f2.4 and FA35 f1.7. I enjoy their outstanding image quality when carrying a bag with several lenses or changing lenses is not an issue.

I also have the DA17-70 f4, which has much better optical performance and is brighter at 70. Today it has been replaced by DA16-85, which I probably would have bought if I had not had the DA18-135.

But these lenses are much bigger, the difference is quite sensible when hiking or sightseeing, they start wider, which is very nice, but you do need another lens for telephoto, for instance I have DA55-300, which is OK for shooting wildlife handheld, but is a big lens to add to your bag, and DA50-200, which is very light and compact but not so good as DA18-135 on their common range.

What I like in DA 18-135 is it is a no-brainer, which delivers nice pictures all across its range.
The center sharpness allows severe cropping on the 24MP K3. The edge softness doesnt matter that much, as the corners are out of focus in portraits or action shots, and you get acceptable sharpness for landscapes when stopped down at f8-f11.

There are better specialized lenses, but, when I go out not knowing the kind of scene I will be shooting at, I know that DA18-135 can be my only lens and yet will do the job, even in dusty or wet environments, without having to carry other lenses and change lenses in the field.

When mounted with DA 18-135, my K3 or K30 are not bigger than my superzoom Fuji X-S1 small sensor bridge, has almost the same versatility, and is about the same weight (lighter with K30, a bit heavier with K3). And it delivers APS-C IQ and DSLR instant PDAF even in darkness.

Lens Review Date: August 26, 2016 I can recommend this lens: No | Price: $500.00 | Rating: 6 

Pros: Range, silent focusing, WR
Cons: Horrible fringing, corner sharpness
Sharpness: 6    Aberrations: 4    Bokeh: 7    Autofocus: 9    Handling: 8    Value: 4    New or Used: New    Camera Used: K-S2   

When I got this lens in a kit with my K-S2, I wanted to love it but I just can't bring myself to. The silent focusing is nice, the WR is convenient and the range is pretty good. But it is expensive, especially bought on its own, and the lack of corner sharpness and horrific fringing which seems to be a different colour in every photo and is often hard to completely remove in Camera RAW, mean that I look at a lot of photos thinking how good they could have been if I hadn't used this lens - even if I'd had to use a shorter but better lens and crop. It also makes the K-S2 front heavy, and it hangs awkwardly off the strap.

You would expect some compromises in a long range zoom, and I accept that, but my copy of this lens, at least, does badly compared to my Tamron 18-200 Di II. The Tamron also struggles with fringing, but its corners are much better and it cost a third of the price of this lens. My 1st generation 18-55 gives the same quality photos as the 18-135 within that range.

If this lens was cheaper, I would overlook a lot more of its optical issues. But since it commands such a price premium over other long range zooms and the 18-50, I can't recommend this lens at current prices.

Lens Review Date: August 10, 2016 I can recommend this lens: Yes | Price: $415.00 | Rating: 9 

Pros: Build quality, WR, great zoom range, sharpness
Cons: Soft in the corners
Sharpness: 9    Aberrations: 8    Bokeh: 9    Autofocus: 9    Handling: 9    Value: 10    New or Used: New    Camera Used: K-3   

The 18-135 is a great general purpose lens. It is ideal for beginners and enthusiasts as well IMO. When I am not sure exactly which lens to take, I generally pick this lens. It is wide enough to get good street shots, and just long enough to get that tele shot you might have missed with a shorter lens. It is not " macro " but it can focus quite close to give some impressive nature photographs of insects and flowers etc. The WR is a bonus with this lens if shooting close to moving water on in the snow. The autofocus is very reliable and trustworthy on my copy. It is a very good companion for the K-3. I can highly recommend this little gem of a lens

Pros: Weather Resistance, Walk around
Cons: not enough sharp in the corners

There are many reviews for this lens in this forum. I have just used this lens for three days.

My points:

1. Best walk around lens, I still haven't utilized the WR option, though I used it without fear during misty day on hill station. All other super-zooms Tamron, Sigma 18-200, 18-250, you can not take it out during rainy season. Also you may miss 135-250 range!
2. If you compare with Tamron superzooms 18-200, it is sharp. But the images from 18-135 are not sharp at the corners. So you tend to keep the subject at the center.
3. The lens produces sharp images at f8, but you must know in which condition you really want to use it.
4. Autofocus is not a big trouble.
5. Manual Focusing is bit difficult.

I suggest this as a beginner lens instead of 18-55 WR.

Here are my photos taken two days before.

Lens Review Date: April 10, 2016 I can recommend this lens: Yes | Price: $200.00 | Rating: 9 

Pros: Convenient range, build quality for the price, excellent AF, IQ notably better than 18-55 kit zooms
Cons: Some aberrations, not so sharp towards the long end
Sharpness: 8    Aberrations: 8    Bokeh: 8    Autofocus: 10    Handling: 10    Value: 10    New or Used: Used    Camera Used: K-5 IIs   

Since I started with Pentax, Iíve been through a number of cheap normal zooms: the DA18-55 version 2 was OK at first, but after getting some better lenses, the output seemed flat; the F35-70 was very nice, but prone to flair and limited in range, the FA24-90 was a pretty good lens, but my copy did not inspire confidence mechanically and eventually the AF starting playing up. Now Iíve got the DA18-135 and I think I could have saved myself a lot of hassle and frustration by just getting this as soon as it was released.

My intention in getting this lens was to have a convenient walk-around lens for when Iím on trips of with the family and I donít want to hold people up by swapping primes all the time. I was also looking forward to quiet focusing and having a solidly made WR lens to go on my K-5 IIs. It has quickly proved to be pretty much perfect for this purpose.

I was pleasantly surprised by two aspects of this lens. Firstly, the quality of the bokeh is really quite nice at the long end. It means I can get some nice isolation in portraits if I have the space to step back far enough (not always easy here in Japan). Also the autofocus is much better than any other Pentax lens I have used - very quick and with little hunting. On my first trip with this lens, I was on the back of a boat with seagulls swooping around chasing the vessel. I have no experience of shooting birds in flight, but I was amazed by how well the lens and the K-5 IIs could keep up. I ended up getting a lot more focused and sharp shots that I would have expected.

Considering the quality and convenience on offer, Iíd recommend any newcomer to Pentax to get this as part of a kit as a first lens. Itís a lot better than the cheaper kit lenses, and it's a lens youíre likely to want to keep in the long term.

Lens Review Date: April 4, 2016 I can recommend this lens: Yes | Price: $450.00 | Rating: 9 

Pros: AF, sharpness, focal length range, practicality, price
Cons: purple fringing, placement of quickshift focus ring
Sharpness: 8    Aberrations: 7    Bokeh: 7    Autofocus: 9    Handling: 9    Value: 10    New or Used: New    Camera Used: K-30   

None of my ratings are relative to price or being a 7.5x zoom lens, I'm comparing sharpness to the Tamron 90mm macro (I've done 100% crop comparisons of the same scene), aberrations to a DA 50 (which doesn't need any corrections) and the SMC A 50mm f1.7 for bokeh (if the Tamron's colours were better, I would favour it for bokeh over the A 50 but that's not the subject of this review). I always apply distortion correction in post-processing and often have to correct for purple fringing in PP as well. There are situations (mainly indoors) where I wish I had a wider aperture in a zoom lens and it looks a bit silly or intimidating (depending on who you ask) when it is extended out to 135mm. I can't find anything else negative to say about this lens, which I've had since September 2013 (I just realized today that I had never posted a review of it here.)

Flare resistance is good for a zoom lens and slightly soft corners shouldn't be a concern unless you are doing art reproductions. Auto-focus is fast, quiet and accurate. It isn't too heavy for the K-30 and the focal length range covers what I need 90% of the time. It's the ultimate walk-around or all-purpose lens, in my opinion. Other lenses can do one or two things better than the 18-135, but none can match it for convenience and overall value. Highly recommended.

Lens Review Date: January 15, 2016 I can recommend this lens: Yes | Price: $455.00 | Rating: 8 

Pros: WR, zoom range, sharp center
Cons: Soft edges with slight CA
Sharpness: 8    Aberrations: 8    Bokeh: 9    Autofocus: 9    Handling: 10    Value: 8    New or Used: New    Camera Used: K-3 and K-5II   

Got this to substitute DA 18-55 and 50-200 KIT-lenses as the zoom range is more suited as a walk around lense. Autofocus also hunts less and sound level of course lower.
Center is sharp, but I have a bit of a problem with soft edges and CA. I use it more or less exclusively when I need a complete WR unit.
Overall it's what you can expect from a low range super zoom.

Lens Review Date: January 6, 2016 I can recommend this lens: Yes | Price: N/A | Rating: 9 

Pros: Nice feel, Weather Resistant, Covers every use
Cons: Dark in low light, Autofocus slow in low-light, expensive
Sharpness: 10    Aberrations: 8    Bokeh: 7    Autofocus: 9    Handling: 10    Value: 8    New or Used: New    Camera Used: Pentax K-50   

It is a really good lens, it does everything, it's WR so you can take it anywhere. It is incredibly handy.

The downside is that the photographs it takes are not the best. It's sharp but dark, the colors need a little boost in post-process and it doesn't really performs well in low light. BUT it is really better than any 18-55mm I've tried (which are Pentax kit and Canon kit). So it's definitively a good zoom for a kit lens, and it is worth the extra bucks, especially for its handyness and the pure happiness it is to hold handheld in video.

This 18-135 definitively is the best "everyday" lens I've tried, it covers everything you could do, but... it's a little dark. Not a biggie as a little post-process gives excellent results as it captures really well the shades of black, allowing to play with exposure and curves without any trouble.

It is perfect for beginners, for video (in good light) and for your everyday life. Just take it for what it is, don't expect taking the best portraits + the best landscapes + the best astrophotography + the best... etc. It is good at everything, in contrario of prime lenses that do better in their own range of pictures.

A great all-in-one !

Lens Review Date: January 2, 2016 I can recommend this lens: Yes | Price: $250.00 | Rating: 9 

Pros: color rendition, handling, build quality
Cons: low-light capability
Sharpness: 10    Aberrations: 9    Bokeh: 9    Autofocus: 8    Handling: 9    Value: 9    New or Used: Used    Camera Used: K-50, D-3   

Firstly - Pentax, you have to do something about all the acronyms in this lens' name... it's just ridiculous....

After that being said, this is a very versatile lens.... it has a permanent spot in my bag and is probably mostly likely to be used as a walkabout lens... Typical Pentax color-rendition, which is to say a bit warmer than what you find with Sigma or Tamron lenses, which is a good thing.

It does not like low-light situations; if you can't bring up the ISO to help it, the AF will do a fair amount of hunting before either finding your spot or just giving up.. fortunately, it is a quick-shift lens, so you can always take control away from the AF system and do it yourself...

This is my first 'modern' DA zoom lens, in that the focus ring is between the zoom ring and the camera body; that took some getting used to; plus, with the quick-shift, the focus ring has almost no tactile response whatsoever and will spin all the way around the barrel.

I switched about halfway through the month from my K-50 to a new K-3 and did start seeing better resolution and overall better shots.

About the only truly negative feedback I can give is the low-light performance; but that isn't why you buy this lens to begin with...

I used this lens in the December Single In Challenge; here is my Flickr album for the DA 18-135mm:

This lens has become a favorite and accompanies me on all outings. I find it very useful indoors and outdoors. IQ is satisfying and I have taken hundreds of shots in the few months I have had it. This is a good lens from beginner to advanced level users. I bought This lens at a good price and they are cheaper now. Buy one and enjoy it.

Lens Review Date: June 21, 2015 I can recommend this lens: Yes | Price: N/A | Rating: 8 

Pros: Sharp, WR, Versatile Range, Excellent Build. Silent DC Motor
Cons: Distortion at the wide end, Calibration issues (my copy)
Sharpness: 9    Aberrations: 8    Bokeh: 8    Autofocus: 10    Handling: 10    Value: 10    New or Used: New    Camera Used: K5, K-01, K-r   

I've had this lens for at least two years and thought it's time to share my experience. As with most Pentax WR lenses, the build quality of the 18-135 is excellent and a perfect match for a K5. Unfortunately, my initial experience with this lens was rather disappointing. The images produced were mediocre at best and easily shamed by a 3-Megapixel point-and-shoot. My first thought was the negative review by Photozone was accurate and that I should just return this lens and forget about it. In the end, since it was still under warranty I decided to give it a second chance and sent both the body and lens to CRIS for evaluation. As it turned out, it was just a calibration issue. Not only CRIS recalibrate the lens to factory specs, but they also calibrated both the lens and my K5 together.

Coming back from CRIS the lens had a whole different attitude. It may not outclass primes but the IQ produced by this 18-135 were impressively sharp across the frame especially stopped down at the longer end. Color rendition and contrast are typical of Pentax DA lenses (Excellent). Focusing is quick and accurate. Some users have commented on this lens at its best around 24mm-40mm range. Strangely enough my copy's weakest point is at the wide end, while the sweet spot is at 80mm-100mm range.

Excellent build quality
Silent DC Motor (Ideal for live-video AF on a K-01)
Sharp especially stopped down at the long end (My Copy)
Fast and accurate focusing
Versatile range

CONS: (Typical of Long-Zooms)
Barrel distortion at the wide end
Boarders tend to get soft especially at the wide end at large aperture
Calibration issues which needed to be sent in for warranty services. (My Copy)

Being a WR super-zoom capable of delivering very good to excellent IQ, this lens ended up as my most used for general walk-around on a K5 and produced hundreds if not thousands of keepers. Oddly enough, for my usage I found it to be better suited on a K-01. Not only for its versatility and good IQ, the silent DC motor is also ideal for live-video AF. If it weren't for the initial ďnegativeĒ experience I had with calibration which required sending the lens for services, I would have no problem giving it a higher score.
