Dear all
I have Pentax K70 and a Nikon D500. I love them both equally. K70 is not the best APS-C camera but small enough and cheap enough for me to walk around the city at night

I never use or seen an all-in-one lens. I hear lots of good reviews about the Nikon 18-300mm VR f/3.5-6.3 DX AF-S G ED (I think It has a few versions). But I did not hear much about the Pentax.
How are they both compared? using with K70 and Nikon D500

Can the Pentax-DA 18-270mm F3.5-6.3 replace both the kit lens (18-135 and the 70-300 (like the Tamron AF Di LD Macro 70-300mm F4-5.6))?

Thank you all

The 18-135 is the better of the two. As the 18-270 is not a Ricoh/Pentax designed lens it misses the quick shift manual focusing. The 18-135 is not really a kit lens, but it is sold in a combination with the later camera's. The 18-55/18-50 and the 50-200 are the "real" kit lenses. The 18-270 is also sold together with the K70 and it was not introduced as a kit lens...
The 18-270 could replace the 18-135 and the 55-300, but you loose some IQ!

@pepperberry farm you’ve used some super zoom lenses in the past. Care to add your thoughts?

I have the Tamron 18-270mm (the basis for the Pentax 18-270mm) for my Canon 40D. I also have the screwdrive Pentax 18-250mm. Of the two, the 18-250mm is the sharper, as reflected in the user ratings on this site. On the plus side of the the 18-270mm is the silent - but slow - focus motor, on the plus side of the 18-250mm its slightly better IQ. The choice is up to you.

Thank you all. I have the 18-135 for years with k70 and quite happy with the results but sometimes I need a quick reach.

How about the comparison with the nikon?

Ah I see. I just remembered that I got them together 😜.
I'm sure going to 18-270 the quality would be lower but hope still acceptable.

I have the 18-270 in a box, waiting for the day my wife's Sigma 18-300 becomes unrepairable. She loves the Sigma on her K-70 and I kick myself for not buying two when they could be had new. I suspect the Pentax lens will not perform as well, based on reviews. Too bad a better option is unavailable, new.

You already received some good advice.
I have the DA18-250mm, DA18-270mm and DA18-135mm. Let me share my own experience.

I love the WR and small size of the DA18-135mm, A great lens, but a little short to be an all-around zoom lens IMHO. I tend to use it when I need WR.
The DA18-250mm is a great lens. The AF is a bit noisy, but this 'oldie' is a 'goody'. While not WR, it is solid and rugged IMO.
The DA18-270mm is a good lens, small, a bit longer than the DA18-270mm and much more silent.

On my K-7, K-01 and K-3 camera bodies, these 3 lenses are all very good for what they are: decent 'all-around' lenses. This would be true also on a K-70.

But,... my K3iii outperforms the DA18-250mm and DA18-270mm. I starts to see (too much) the optical flaws of these lenses. Thus, I use mostly my primes on my K3iii.

I hope that my comments may help.

I have the Sigma 18-250. It's decnetred and useless on most cameras. Not so bad on the 12 MP K-x we bought it for, but still noticeably soft on the left side of the frame. These lenses are always a crap shoot. You can get good one, the top of the sample variation is acceptable, the middle and low end of the sample variation curve, not so much,

When I discovered the Sigma 18-300 was not available, I bought their 18-250 used, which I keep on my first DSLR, a K-5 (which incidentally, was mfd. on my birthday the year I bought it, new: 2011), and get acceptable results from it as a "just-in-case" camera I keep in my pickup truck.

That's not right for Germany. I still have the original Pentax Box where both K-5 and DA18-135 were packed inside - bought, I think in April 2011.

My k-50 was boxed from Pentax with my 18-135 in a single box kit and I’m so glad it was! It was a premium kit rather than an entry level kit. I paid $700 for the kit and look at that as money well spent as it brought me back to the hobby after a hiatus.

The kit lens is the 18-55. The DA 18-135 was specifically designed to be a step up from the kit lens. That was actually in the release information way back in the day. They do include them in the box, but if you choose, you can save a bit by finding one boxed with the 18-55. The DA 16-85 is way above lit, but still packaged and sold with the camera. I've also seen the 40XS, 50 1.8 and other primes in the boxes.

I'd be a little concerned about labelling anything that comes in a box with camera a kit lens. Many of the lenses that come in the box are upgrades from kit. Something that when I had 3 18-55s I was grateful for.

So was the 16-85 with the K-3 Mark II, just in one box the two of them, but you can call the 16-85 hardly a kit lens...

I know that it differs from country to country which lens is sold in a kit with a camera. As far as I remember here it was with only the 18-55 on offer.

Question is, is it allowed to call a lens delivered as part of a camera lens kit in an original Pentax box that names both items, a kit lens - or not. In the end it isn’t important to me.
