just received my Pentax 18-135 mm lens
Dec 29, 2010

Very nice lens indeed. Small size and well build.
Did some comparisons between this lens and the 50-135 mm and the 18-55 kit lens.

Its IQ is indeed somewhere between the kit lens and the 50-135 mm but closer to the 18-55 then to the 50-135. My educated guess an improvement of 30 % over the kit lens. As such not a spectacular improvement.

Very happy with the lens as it is an ideal walk around lens. But for the more serious work i will return to the 31mm/77mm and the 50-135 mm lenses.
Considering the image quality rather expensive.

Conclusion: very convenient, improvement of kit lens but somewhat expensive, very usefull addition to my current lenses.

Maybe not a spectacular improvement but given the much greater focal range and the compact size I think it's a good achievement.

Yes, it's not quite cheap.
I ordered one too 7 weeks ago but it's still in backorder..

How does it compare to the 55-300?
Thanks for the report BTW

But if you would like to stay within Pentax lenses and have the same range with same or better IQ you would need to go with either...

DA16-45 + DA55-300

+ ~ same price
+ 16-18mm and 135-300mm

\- Dual lens
\- No WR
\- No 45 - 55mm
\- Heavier, bulkier

DA17-70 + DA55-300

+ 17-18mm + 135-300mm as a bonus

55-70mm Overlap

\- ~ 2x price
\- Dual lens
\- No WR
\- Heavier, bulkier

DA*16-50 + DA*50-135

+ WR
+ Better IQ
+ 16 - 18mm

\- ~3x price
\- Dual lens
\- Heavier, bulkier

Even as a pretty expensive lens, I would like this one.

+ Seems to have good IQ, I am happy with the sharpness with my copy of the 18-55II, but the bokeh isn't really to my taste. Rounded ap. blades on the 18-135 might make a huge difference here.

+ 1 lens. One compact super zoom with decent IQ to complement my primes when on travel. This is what I use my 18-55II for today, this lens will probably do a much better job.

+ WR - Very useful for a "go everywhere" lens.

Very usefull indeed, when shooting and requiring or desiring at least WR, the 50mm split in the DA* line up can be very annoying.

Despite what s being said in many * vs WR debates, I think the 18-135 WR feels more solid compared to at least my 16-50 (maybe due to compactness). Also one of the sliding tubes is metal and not plastic (I know, I scratched it already )

Good question.
Will do a comparison and report back.

You are quite right.

A lovely lens and an excellent match with the K5. The build quality matches the quality of the K5 and the range is very usefull. I did have the 16-45 mm lens but did not use it very often. Despite the good quality i did find its range somewhat limiting.
Sold this lens recently.

Most of my pictures exceed the 50 mm range hence my love relationship with the fantastic 50-135 mm lens.
I can only recommend the 18-135 mm lens.

Untill now i always took 2 camera's with me. The Pentax k7 with the 50-135 mm lens and Leica Dlux 4 for the range below 50 mm. For the longer range i use the 50-300 mm.
This lens was a surprise to me, low price combined with an amazing quality.

I do have a 31mm ltd and a 77 mm ltd. The 31mm did disappoint me but i love the 77 mm. I consider to sell the 31mm and use the funds for a 60-250 mm lens

Following your question i did a comparison between the 18-135 mm lens and the 55-300 mm lens.
My observation are as follows:

at 135 mm:

  • the 18-135 performs slightly better at 5.6 and 8.0

  • the 55-300 performs slightly better at 11.0

at 85 mm

  • the 18-135 is slightly ahead at 5.6, 8.0 and 11.0

at 55mm

  • same as at 85 mm

The iq differences are small. My copy of the 55-300 is really very good and the 18-135 is marginally ahead of the 55-300.

This again proofs that the 18-135 to be a very usefull lens with the right balance between convenience and image quality

In reply to Johan Josefsson, Dec 30, 2010

My solution is:

for convenience - walk around:
Pentax 18-135 plus Pentax 55-300

for best iq

  • Pentax 50-135

  • Pentax 31 mm

  • Pentax 77 mm

These are the lenses i own and i am aware that for the best iq i have no solution for the wide angle range.

Thanks for that comparison Goto, if its as good as the 55-300 has rounded aperture blades, light & weather sealed I can't see you can go wrong - fast focus too I hear.

Zooms allow you to get the shot and if its something really special you can always mount a * or prime.

Yes, but how about the 18-55 WR and 50-200 WR? Slightly cheaper I suppose...

The 18-135 does look good as a one lens solution in that range, for the money and goodies you get with it.

Good comments..
In reply to gotompoes, Dec 30, 2010

Not sure it would be a reasonable expectation for it to equal the 50-135 f/2.8. However, compared to other similar range offerings it has some very attractive features (at least IMHO on paper - don't have one yet).

First: I "think" it is the only WR zoom of this broad a range (FOV range) out there regardless of the manufacturer.

Second: Combined w/the WR K200, K10/20 or K-5/-7 that is a very very attractive feature set/kit!

Third = Price: I'm not sure that given the WR (and no one else offering that) the price should be considered too high. I think we would all "like it to be" cheaper... :-); however, in reality the WR feature I believe justifies the additional expense.

So - given the "good" IQ, I see it as a total winner! Again, thanks for the comments!

Yes there is 1 solution for wideangle range that is Sigma 8-16 f 4.5-5.6 the best IQ
in this class.

I thought a thread about a lens without any pictures would not do. Bought this lens a week back and had the time two days ago to go out and take some pictures. It is about what I expected in image quality. Build quality is way beyond what I had imagined.

All shot with K10D, converted in LR 3.3, no pp done except for one horizontal flip.

But if you would like to stay within Pentax lenses and have the same range with same or better IQ you would need to go with either...

From what I have read so far, the 18-135 seems to be a little bit above the 18-55 and 50-200 wrt IQ, more like DA55-300. But let's wait for some additional tests before drawing too far reaching conclusions.

Before the 18-135 I had a DA 16-45/f4. Since quite some time has passed since they designed this lens, I expected lens quality in general to have improved. Furthermore, the 18-135 costs about 2 times as much as the 16-45. Thus, I hoped (expected) that the 18-135 (7.5x zoom) would be comparable to the 16-45 (3x zoom) quality wise. I hoped that the pro's of the steeper price and newer design would make up for the con of the bigger zoom range. This is what I expected and this is what I found to be true, looking at the pictures I took (I did not shoot any test charts). I did not expect an improvement over my 16-45 because there is just so much you can expect from a 7.5x zoom lens.

The build quality of the 18-135 is much ahead of my 16-45 which had a wobbly inner barrel. The 18-135 feels very solid and the focusing feels faster (on a K10D). Furthermore, I like the hood of the 18-135 more than that of the 16-45. The 18-135's hood fits neatly around the lens when reversed where the 16-45's hood was quite a bit bigger and bulky.

Ahead in what way? MTF resolution? It's hard to believe the 50-135 would be better for vignetting and PF. What about colour and contrast? Most of the 18-135mm photos I've seen so far seem to have a weird bluish colour cast, but I don't know if it's the way the lens produces colour or the K-5, or the combination.

Thanks Bert. My 16-45 is very good, I rate it just above my 55-300mm. If the 18-135 can match the 16-45, I will most definitely get one. I no longer use the 18-250 because it was too much of a compromise in IQ compared to the 16-45 + 55-300.

Have you noticed anything different about the colour rendition of the 18-135 vs 16-45?
