Hi, I'm considering acquiring an all-purpose walkabout lens to pair with my K5, I'd welcome your thoughts on the topic.

I have plenty of lenses covering the focal lengths, but that's the point, it's always two or more, and when I've got two young kids juggling a lens swap isn't worth missing the moment, hence the consideration.

Also I've got a friends wedding to go to soon at which I'll take some casual pics when I haven't got at least one eyeball on the little tykes ! Plan A for the wedding is to take the 17-70, and if I have space, the 50-135 and a flashgun. Or just the 50-135 and settle for closer in shots.

I had considered the 16-85 but at 500 it's a bit more than I'd like to pay, considering it's not much extra reach over the 17-70 I already have and it's not a DAstar.

On the surface of it an 18-135 appeals, it nearly covers the wide end (prefer if it went down to 16mm) and at 135mm it ought to be long enough to get close to the subject.

However the review here http://ww w.photo zone.de/pen tax/597-pentax_18135_3556?start=1 (just remove the spaces) looks dire quite frankly. I prefer lenses with relatively even centre to edge performance, which is my taste for landscape lenses. This definitely isn't the case if the review is typical. I see dpreview can't be bothered to test anything longer than 55mm in pentax.

So any 18-135 users have thoughts ? Is it worth the 350 ? Does convenience outweigh the image quality ?

Alternative is a 18-270 which is a bit pricey, I haven't located any reviews of this.

Or a sigma 18-200, poss the DC Macros HSM version, I haven't located any reviews of this, I fear that at approx. 200-250 this may fall into the you get what you pay for category !

Thanks for taking the time to pitch in your thoughts. I'll apologise in advance and say I've not got much spare time for forum chat so sorry if it takes me a while to get back to you and points aren't all answered. Cheers

All I can say, my 18-135mm came with my camera as a kit. I assumed I would just sell it on as I have the posh f2.8 zooms + others. NO WAY am I selling it, light compact and a good performer in my opinion. Mind you my KS-2 and 18-135mm together were not that much more than the price you quote above for the lens alone, I just happened to need a new camera at the right time.

I would have no hesitation recommending the 18 - 135....mine virtually lives on the camera. I bought mine new, but check the classified section on here, they come up every now and then.
I must admit that prior to purchase i was slightly put off by some reviews, but in contrast, actual user reviews were very good. I would put myself i that "actual user" group now, and i think its a great lens.
My advice would be to buy used, then if you dont like it, sell it on for what you paid....nothing to lose.

SRS have had offers on the 16-85, perhaps they still do. (Can only ask or try the coupon code at checkout!)

The extra at the wide end can be useful.

I love my 18-135 and it is my walk around lens of choice. The only real downside (at least with my copy) is a far amount of CA at the edge of the frame, particularly in very strong light. However, it is easy to fix in processing.

I'd have no hesitation in recommending it. These were all taken with it (just cut & paste into your browser):-

18-135 wouldn't go out without it

1. Sold 18-270 in both Tamron ( slightly shorter range) and Pentax ( not good outside mid range mid apertures, high shutterspeeds)

2. Sold 16-50 DA* SDM Issues

3. Now have DFA 24-70 and DFA 28-105 and still the 18-135 which I bought on a very special offer because the 16-50 was a little limited and a little unpredictable.

Read John Rileys test at the time and thought I would give the 18-135 a go.

I have kept my first well used and somewhat Battered K3 body just for the 18-135 which is my travel/ holiday and walkabout lens, even though I have a K1 and K3II .

However the 18-135 is much more capable than any old walkabout kit lens and my PU portfolio has numerous shots taken with this very underated but fantastic little lens.

See below ( sharpness is stunning)

Like you i wanted the 18-135 and was put off by the price and after reading the review was even more put off about how soft it was in corners and towards the middle, so in the end i went f or the Tamron 28-75 and it is sharp, Tamron has made a different modal now 24-70 but it is a good few pounds more

All the best Dave

Thanks for your thoughts and the pointer to Mr Riley's test. I haven't been on the site in ages and I hadn't realised the PU reviews included MTF info now so didn't even think to look there !

I've been surprised the passionate endorsements here, I was expecting a trend something more like 'it's okay at f8 / it's handy not to have to change lenses / keep it away from the extremes and you'll be okay !

Hmmmm, food for thought !

I've a copy of the latest Sigma 18-200 and I'm rather impressed by it.

Haven't tried an 18-270 or an 18-200. It just seems too much of a compromise to me.

3 years ago, I went to Appleby Horse fair with the K5, and purposely only took the 18-135. Here's some photos.

I've had my 18-135 for about 4 years and used to have it on my K30 or, more recently, K3-II most of the time and have been generally happy with it as a "walkabout" lens. However I've recently been using it a lot less as I've become disappointed with the accuracy and speed of the autofocus at the long end of the range, particularly with moving subjects. This also happens when using back button focus.
I recently picked up a Tamron 17-50 f2.8 cheaply and am impressed with it and leave it attached to the camera. If I anticipate needing something a bit longer I just put my Tamron 90 mm and, sometimes, my Pentax 1.4x convertor in the bag. I know it means a extra weight and changing lens, but I reckon it's worth it.

FWIW, my walk-around lens are the 18-135 and Sigma 4.0-5.6 10-20 Sigma (very early non-HSM version) - and the latter was used for 90+% of the shots I took in Tuscany a few weeks ago because of the confined spaces we visited. OTOH, would not sell the 18-135 because it is very useful in more open spaces - although I think my very old, original version (399 when I bought it!), does not have the best in the way of contrast. Hopefully the later versions are better in that respect.
K-3 II, K-3 and a K-70 from SRS (having now relegated the K-30 with the Hacked K-50 f/w to being a backup body) , & some Sigma and Pentax lenses (and a lot of old 35mm gear!)

Hi Blade,

I too have a k-5, which has a 18-135 WR on it permanently. Go ahead and buy the 18-135 from the classifieds as suggested by Unlocker, and believe me, you will not regret. It is a quiet and very efficient lens.

K-5, K-7 and K10D, Pentax 18-135 WR,18-55 WR,Pentax 28-105,Sigma 28-300, Sigma 28-80 (Macro) and Pentax 50-200 WR.

I have the 18-135 and the 16-85. I like both!

The 18-135 is compact, light and gives a very good range. The 16-85 is a better lens but it is bigger, heavier and does not have the higher end range. Most of my photography is landscape and the 18-135 does this well, especially when you only want to take one lens, climbing a mountain or no room for lots of kit. It likes the light and if it is reasonably bright (i guess when its stopped down a bit) it gives good results.
The 16-85 is sharper and is very resistant to flare. It is a fair bit bigger and heavier but if i'm doing photography, rather than just taking the camera, I will chose this one but will need to think about taking another lens as well, if I may want a bit more reach.
It's the old problem. Do I need the best quality or do I need to have it ready to get that picture. The best camera/lens is the one you have with you when the picture presents itself!
I have shots with both these lenses in my gallery, feel free to have a look.

I thought I would sell the 18-135 when I got the 16-85 but it hasn't happened yet and i don't think it will. Best thing to do is just buy both!
