Oh sugar, you mean to tell me PRY, that its the same issue as in the older SDM lenses, that is in the body of the K70.
"I don't believe it"
Just to add a bit of context, my K70 performs very well indeed and my secondhand da200* is top notch and very much older second hand purchase of a da50 135* performs perfectly even if left for six months or more.
i know this because of my newer K1 which i could not leave down.
On the other hand for balance purposes, My brand new 16 50* (older SDM model) later that year 2019 sadly packed up its SDM drive about !8 months later.
Now you could be onto something also PRY because i attached the same lens 16 50* that was a dead SDM to my K1ii and guess what, it slowly started to wake up and i mean very slowly and by the end of the day the lens was performing adequately for my purposes, i never revealed this as im sure plenty have tried this long before myself.
But you do have me wondering Note to myself give my K70 ago more often than not

Well regardless of the perceived improvement in the new K70 updated version because of component shortages and probably no other reason in that, they had no other choice.
I am so glad that i purchased my own k70 from SRS for the princely sum of £399 brand new in January 2019.
I hope not to curse it but aperture block is only highlighted by the people it happens too, and that would be a tiny proportion of k70 owners that might be rattling off photos in rapid modes for extended periods, filling the buffer on a constant basis and expecting every single model to be able for that continuous abuse. I prefer a gentle approach with entry level equipment.

I wouldn't be to harsh on your self Loadoftripe, as they were contrasty conditions with harsh light so the shadows are going to be blacker and the highlights will be whiter as in the histogram. The sky can be the enemy in daylight photography.
Some of your night photograghy of city scenes and sunset skies are excellent and processed very nicely.
I think you use Rawtherapee if i remember correctly for your editing and excellent it is for raws, but applies Its edits globally(the entire image) but does have a graduated filter to position around so on can lighten or darken separate areas of the photograph and it also has a lot more but it is nerdy to navigate.
Less is more and when you click local contrast for instance, the preset built in is usually pretty accurate, same with sharpening and other settings
it also does my downsizing for this sight

No 3 for me jvs, it has the dept and scale of a wonderful landscape scene, very nice holiday

Absolutely agree with that comment, it is indeed a stunner

I used MPB to buy a lens that was described like new
I am happy to report, that is was like new.
It was MPB Germany, but i tried one day to get a quote on on a couple of lenses that i was willing to sell.
Even though the description was honest, No quote but i would ave to send the said lenses to them for evaluation.
Disappointing really considering the hassle, so No i said not willing for that long drawn out process

That needed to be said, and welcome MXLX, Hope you have a few photographs to show.
When I first visited i couldn't even downsize a photograph to appear correct on the site.
So many helped and that's what matters

My limited experience of the Pentax DFA 28mm to 105mm
An excellent lens but it does require good lighting conditions to show it at its best and it is excellent for that purpose, or else a tripod is needed, yes you can bump up iso on the K1ii pretty significantly but it won't render as nice on the K1ii as some other lenses with similar high iso (probably user error on my behalf) .
I would consider it an excellent daytime lens in bright conditions and it is a match for all and betters most in that category
A great travel companion because of the lightness and range but difficult in low light conditions as in the heavy overcast northern hemisphere, wet, damp, drizzle, lowlight winters.
A summer lens is where it shines unless you bring a tripod.
Loads will disagree my thoughts but

Great set Lenny, love no 4 for the B@W contrast and no5 for the punch of the poppies and no6, how on earth did you manage to walk up such a steep incline but i see later on, that it was for a call into the Weavers Real Ale House
Thoroughly enjoyable, all of them

Just tuned in and this needs to be viewed large to witness wonderful detail, yet softens the heart.
Great photography and stunning model
